About five minutes after we finished filming, I realised that my last line should have been "thank you for your as-cyst-ance". Ah well!

@Bot Jake No

hello

Everyday when Tom Scott uploads always a banger

We love you Tom

REUPLOAD!! the Pun's must flow...

Finally. The Tom Scott unboxing video.

...this piece is referred to as a cyst in the users manual. It was kind of hard to get out of the packaging, so unfortunately it burst in the process.

@Jannik Heidemann i guess you will just have to order a new one, i dont think they sell replacement parts.

With your subscription, every month, you'll get a new box, with a random part of Tom Scott.

Franka Potente would be proud.

@Fity Bux that is creepy af and I wouldn’t wanna be known as the guy who orders Tom Scott parts. But I’ll wish I know someone who does.

I find it hilarious that the surgeon emotes with the little grabbers while he talks just like how we would normally gesture with our hands.

The robot speaks Italian fluently 🦾🤌🤌

Anybody that's used any kind of robot for a long time will eventually develop that kind of habit. I've seen a construction worker point and gesture with a backhoe.

It's a natural human instinct that comes from familiarity with the tool. Just like how we point with sticks.

@HiddenWindshield yep! It’s part of how we subsume our sense of self into the tools we hold as we’re familiar with them. Happens with musical instruments and vehicles too

@Kaitlyn L dude, we're all humans, we know we emote with dead things, the OP even said so, you all don't need to mansplain this to us.

Every horror movie names their medical companies Lazarus for a reason

That reason is because it references a Bible story, and cultural references work well for brand awareness, which is why we have so many reboots and sequels instead of a constant stream of new properties

Usually it's less of company and more of a product, procedure, or project, but sure.

And Doctor Who

You'll see it in a lot of storytelling, especially stuff that isn't original within the last 10-15 years. It is being phased out because people are a bit sick of it. But tying things to religious and/or biblical notions is a stone cold classic in narrative and storytelling due to symbolism and what not.

Hey the Lazarus Project brought Shepard back and it wasn't all bad

"So they have artificially given me a cyst on my left kidney" -Sentences only Tom Scott can say with excitement

Imagine they didn't give him an artifical cyst and that was just what the 3D scan actually recorded

@Freddols “so, good news and bad news…”

@Freddols At least it would've been good timing. He's already in a hospital room.

​@Vigilant Cosmic Penguin hello Tom Scott

​@StalinWasBallin Tom Scott

"Lazarus 3D offered to show me my own organs, not in a screen, or in a visualisation, but in a back alley behind Greggs"

First robo Tom, now copied Tom's abs. Tom is definitely attempting to find a way to clone or otherwise copy himself.

Tom will eventually make a brain scan of himself, create robotic organic copies of him to achieve inmortality (he doesn't seem to age anyhow) and make videos forever, we will have Tom Scott, tenth iteration talking about the colonies on mars and why one of them is called BigChungusburg

They will all be called Musktown, just different numbers

I for one welcome our red shirted, soft spoken, informative replicant overlords.

@francisco L Well, he already made that brain-uploading video - Welcome to Life(TM)...

With enough videos/"excuses to copy parts" and then a finale, he WILL succeed.

5:56 Love how the surgeon says he goes for "style points" by trying to take out the cyst intact.

... a la Dr. Pimple Popper 💦

SSS Rank

@Blue Boy Smokin' Surgeon Style!!

I don't think it's impossible to have a Davinci accessory that does a little bit of suction. They could pop the cyst and vacuum the fluid.

That's what happens when DMC players become surgeons

I always come away from your videos feeling educated and entertained, but this one was a whole 'nother level. Thank you!

Diddo

This was a really good one

Watched tensely lmao

It's "whole other" not "whole nother"

@ToTheHorizon *whole 'nother

Dream: face reveal. Tom Scott: 3D printed abdomen reveal.

I love that she said it’s a trade secret. I think it’s pretty public knowledge that biocompliant multimaterial printing has existed for a while now. I work in the research and production of biocompatible replacement matrices for big printers like the Stratasys j750 and j850 (and would love to show Tom) and for bespoke bioprinters for specific circumstances. BoneMatrix and TissueMatrix are both mass produced and regularly used. Other custom options exist as well for various research purposes

Maybe theirs is a slightly improved model? Or just which they use how is the secret?

I worked with the 750 for 4 years. The 850 DAP is a gamechanger with the new bone and tissue matrix! Can't wait to play around with it.

Contact him on his contact address. I am sure if your company are willing, his team can set something up.

please contact him!!

They likely have a different way to do it with its own qualities, that they may want to capitalise on. Just because we can already do it, doesn't mean the process or the end result can't be greatly improved in some ways.

Idea for a Nebula original: get a 3D scan of Tom's entire body and use it as the basis of the world's largest game of Operation (or the closest legally distinct knock-off). Get a bunch of other YouTubers/Nebula creators to play and Tom can only watch (in horror)

Please link to the Kickstarter 🤣

William Osman will bring his battle bot.

Never mind random YouTube and Nebula creators - can you imagine the Technical Difficulties crew playing that?!

You went to a company called "Lazarus", referencing a bible story where Jesus brought a guy back to life after being dead for four days, and let them 3D print a copy your organs. Tom, this is how you get evil clones running around.

the truth

Don't forget the talking robot head. Tom is aiming to be come primus-borg.

Tom can never be evil

@Aryan Tyagi Tom can't be evil, but what about his twin Evil Tom? hmmmm

All I can ever think of is Ra's al Ghul.

As a bonus, if you do develop a renal cyst you now know a surgeon who's practiced on your torso and is ready to operate!

Tom: "So they have artificially given me a cyst on my left kidney?" Doctor: *Grits teeth* "About that..." *Pulls out medical folder*

Let's hope evil Tom doesn't write a cease and de-cyst letter.

Good job. I was thinking there must be a "cyst" related joke somewhere in there but I couldn't find one that worked :)

ahahah :D

Evil Tom would only start uploading videos less frequently. wait.......

I was a humanities major but I was able to use the da Vinci machine for ten minutes when I was at uni as part of a event. It is truly amazing. The system has a depth correcting lens system and it feels like you are one inch tall and a coin is as big as you are. It was so intuitive I was able to place a rubber band around a penny using only the tweezers after a few minutes. I still think about that experience

Weird flex for a humanities student but ok

Around the faces of the coin or around the edge?

@Unknown I’ll have you know ALL my flexes are weird.

@Jannik Heidemann across the faces of the coin, dividing it in half so to speak. Placing it around the perimeter was too unstable

I had to have my gall bladder removed, it was a similar type of surgery. Fortunately I was asleep through the whole procedure. I did feel some sympathetic twinges, watching this too.

Right!? I have a renal cyst on my left kidney so it was fascinating to see what the surgery to remove it could look like.

I have upcoming cholecystectomy - how was your recovery?

I've also had a laparoscopic cholecystectomy. Watching this, it was like "that's what was inside of me? I know it's ridiculous, but for some reason, that makes me feel uncomfortable."

@Emma Byrne I'm not the OP, but I had one too and my full recovery took about a month. They said I could go back to work after a week (I was disabled & didn't actually work at the time) and honestly, I can't imagine if I had actually had to go back to work after a week. I was NOT ready. Maybe at the 2 week mark I would have been. THAT being said, I did pop a stitch or 2 in the belly button incision & it didn't really close up until more than a few days afterwards (after I figured out how to tape it closed in a way that every time I moved, it didn't pop open again). I can say that there was a marked improvement in my energy levels after that little bit finally closed up. (but that was a few short days before that week mark.) If that hadn't popped open, I may have been ready to "go back to work" after a week. (All THAT being said, I've had gastrointestinal complications usually for about a day or so roughly once a week ever since. (~8 years later) They said only 4% of people have complications afterward but from the number of people I"ve talked to that had the surgery, far more than 4% have had some kind of issue.)

@Emma Byrne I had a laparoscopic chole a couple of years ago. My recovery was fast and uneventful. I had a tender belly for a few days but I was back at work in a week and back to 100% in about a month. Modern surgery is amazing.

Combine this with the animated head that other company made and you'll have a full facsimile of yourself soon.

Tom Scott Plus Plus

@12 Feet Up Tom Scott Plus Tom Scott.

Replicant Tom is going to be awesome

@12 Feet Up the next one would be Tom Scott sharp

@Julia Fletcher He's been in many situations where if things went wrong we would've gotten Tom Scott Flat.

my mom had complications in a surgery last year to remove a brain aneurysm resulting in brain damage and memory loss. Systems like this could lessen the chances of error in the future and i'm thankful people are spending their lives doing this type of research and development.

I do find it interesting that the feedback from the surgeons was "can we make it less realistic" which actually isn't uncommon for practice tools like this.

Did they let you keep your 3D printed stomach? That would be a very bizzare living room decoration

That would be interesting. A guest asks 'what's the liquid leaking out of it?' 'Oh, that's just the cyst juice. The surgeon was halfway through successfully removing a cyst when they got bored and decided to pop it, just for extra style points. It's very realistic, so they can rehearse all the actions they will then do in the real surgeries' :)

Actually... This is brilliant. My dad currently has a benign tumor on the back of his pituitary gland and he doesn't feel comfortable getting it removed since it's a very rare surgery. This would be a great option

I love how the surgeon is waving his tiny tools as he talks.

I never thought 7 minutes of Tom looking at his own internal organs would be so interesting

Advanced Navel Gazing

He missed the opportunity to massage his own back. That's something I so badly wish I could do :D

@WTFBOOMDOOM I need the 3-d printed body to massage mine...

Based azur lane pfp. Hail ironblood!

Many years from now, this could be a fun novelty gift. You could get someone a copy of your own heart; that'd be very romantic.

And if you get one with lifelike blood, and they later break your heart, you can then ruin their living room :)

Tom is the only person who can get an email from a robotic surgery company and we will all just go along with it

5:34 They really did surgery on a grape

This is seriously amazing technology. I'm sure it's quite expensive and time consuming. But I'd feel MUCH more comfortable doing a dangerous surgery knowing the doctor rehearsed it successfully

Those surgery robots are so cool. The 3d print is neat even as a 3d printer owner and lover the robot is more interesting to me.

"Like you're peeling layers of a grape" They're still doing surgeries on grapes, huh?

Grapes are the practice for when they need to extract the brain from a pea. Sewing it up again with colour-matching thread is the hardest part

they did surgery on a grape

I'm literally going to be operated on my left kidney with a robot in 2 days. The timing to see how this works couldn't be more perfect.Thanks!

Hope it goes well!

Wish you all the luck!

The answer to how they print these, in general terms, is fluid jetting. Essentially, it's the exact same thing as a regular 2D printer except that it has to cure each layer and stack them up. Usually it's done with resins, but this looks like they're doing it with silicone or TPU or some other "rubber" instead of normal resin. The exacts on how they're curing the layers and the type of materials being used are where the "trade secrets" come in. Given the size and weight, I also suspect the process is being done inside of a bath of some sort, otherwise it would collapse on itself as the layers built up.

A stratasys polyjet j8 will do it. They specifically market it as capable. Probably with the research package for the fluids. I use one at a work for similar parts.

@Bobby Dazzler I literally haven't seen Westworld. Didn't know they were showing off 3D printing in it. Cheers though!

Yep, you can have all the correct ingredients, but without procedure, proportions and timings in the recipe, you're going to make a mess. Or spend a lot of time and money finding out, as Lazarus clearly have.

Sex dolls industry would love it. Having different structures inside with different consistencies. If they are able to do that, adding layers of heating, etc. There is research already on artificial muscles that contracts and expands with electric stimuli. That could be the start of animal/human-like robots. Well, even if they are just passive, that's a start.

Michael Reeves made a chaotic version of this robot.

In that case the title would be "I let a madman stab me with a robotic knife"

@Sample text here coming soon on Tom Scott Plus

@Urbanistiq Tom Scott plus Michael Reeves would be the most chaotic video in history. I can just imagine Tom trying to adhere to a semblance of structure while Michael goes off on his seventh tangent of the past five minutes.

A lot cheaper too

@CyclopsDragon I believe they did collab once before, but it might've been in a William Osman video

A hospital near here aquired the same robot and made some public demonstrations where you were able to try it out yourself. I must say, it's completely surreal how the robot is able to 3-dimensionally recreate your movements so perfectly. It feels like you are grabbing the tissues with your own fingers. They also had the equipment that is normally used for surgeries like that and it is way more complex and demanding to work with, truly an impressive feat of technology

I’ve been in the OR with a robot, and it’s absolutely mesmerizing. The surgeon is like a ninja in there, they just tear through tissue so quickly and super precisely. If anyone gets a chance to see a robot in action, I highly recommend

Came for 3d printing but got impressed by that claw machine

If they were at the arcade, that would mean a lot more plushes.

“The claaaw!”

@Bobby Dazzler and like in many videos of tom scott he has introduced old things that I didn't know existed 🤷‍♂️

It's so weird to see the surgeon using the robot arms to gesticulate inside the patient

While the techs, surgeon, and anesthetists are talking shop in a routine, easy part, "I caught a fish THIS big" the surgeon exclaims and motions tearing the patient's artery.

@BlackWolf42 Literally lol'd

good stuff, wish we would spread these techhnologies much faster and make them more widely available ... independend from national/personal wealth etc.

Honestly with the huge costs involved making the organs, then the use of an OR room with surgeons I doubt this is going to take off. It might be helpful in extremely difficult surgeries but it is just too time costly and expensive to be used at all. Even with reduced costs, the fact it would take double the amount of time to perform the same surgery for perhaps a few percentile increase in terms of success rate makes it not viable.

Indeed. There's so much stuff humanity CAN accomplish, but doesn't get done for those who need it for empty financial reasons (not for lack of actual resources, but the whole game of capital/politics/IP stuff). Every day I hate that I live in a world that lets people die so others don't make less money, in thousands of ways across the world.

@05Matz Let's change that by protecting the free internet so it can be used to distribute knowledge regardless of those restrictions! We need to show the world the absurdity until people rebell against the restrictions the legal concept of intellectual property burdens society with. The data must flow on the streets!

@Boop You obviously have no idea what you're talking about.

"We do make models that bleed" made me laugh out loud

This is absolutely amazing. I've never been as excited for the future of medicine as I am now after this video

Finally, an organ reveal. Edit. Reveal not review.

I help teach anesthesiologists through scenarios on a $200k very lifelike dummy. This was cool to see because I've seen exactly how useful something like this is.

YouTube doesn't suck

@Alpaca Fluffy the creators dont. The platform as a whole is a shadow of its former self.

@Youtube sucks now i think they censored your criticism

this is actually quite nice, i think ive learned quite a bit about surgery

That is a) deeply disturbing and b) super cool It's really neat that they can create such a detailed and accurate model for surgeons to practice on and hopefully that shows benefits in surgery outcomes. But oh my goodness, I don't think I ever want to see a realistic model of my own organs and viscera.

Wow Tom, thanks for letting us get to know you on a "deeper" level.

He really laid out his heart in this video.

@Vigilant Cosmic Penguin Yes, he showed some guts and let us see everything he's made of.

@Jason Pogue or showed that he's gutless! What if the lack of digestive system organs in the model is because Tom doesn't have them?

As a squeamish person, this was both fascinating and icky. However, I can see this being an important tool for medicine.

We wish you a speedy recovery, Tom!

I got a 3D printer a few days ago, and I have never wanted to make internal organs more. This is fascinating!

I'm getting an abdominal surgery in a few weeks and this is surprisingly reassuring.

With how great Tom is at explaining stuff, I kinda wanted him to have a go at the robot doing the surgery.

I just had a similar surgery, and I not only watched this video with my jaw on the floor, but with a greater appreciation of their skill and the technology behind it.

2:30 I love the gesturing this guy does with the arms, it really shows how intuitive the mechanism is to use, and/or his skill with it.

Dude, this is amazing!!! This will help save so many lives!!!!

My Job is, to produce medical Videos for training purposes and ive seen lots of real interventions with the Davinci system. Since I see this stuff on a regular basis, I completly forgot how special this actually is and how advanced we humans are. You reminded me of that. Thank you!

Wow, it's amazing how far 3D printing technology has come. I was already amazed by the level of detail that can be achieved with modern 3D printers when I used a resin printer for the first time, but the material range presented here is simply mindboggling. It's a shame they wouldn't tell you anything about the process. Might have to look into wether there's some publicly available research on soft tissue printing.

This whole idea is brilliant. Practice is such an important thing and medical mistakes are so potentially life-changing that giving surgeons a chance to have a dress rehearsal for difficult surgeries could be game changing.

I would love to just keep watching robot surgeries, especially on these models

This has to be one of the coolest videos I've ever seen on YouTube. Not only are the creators of the da Vinci robots absolute geniuses, but then creators of a realistic 3D printed abdomen... wow!

This was fascinating to watch! I am a mental health nurse educator - due to the nature of mental health, we don't have many 'toys' or models; we have to work with real people to develop and refine our skills. I sometimes wish we could have these other options for teaching & development!

This is amazing. It’s a really important technology and should help doctors to train to do robotically assisted laparoscopic surgery. I’m alive today because of such surgery, done by a highly skilled surgeon using a DaVinci robot, so this is something close to my heart, for obvious reasons! Thank you Lazarus 3D for your amazing work, and thank you Tom Scott for making this video 👏👍

This is awesome- especially since I personally knows the doctor performing this surgery. He’s a awesome person. I’m so very proud of him. Great job Dr.

This is one of the coolest videos you have done imo.

I work with these robots daily. I love that you did a video on one with a very skilled surgeon to showcase the abilities of it. Well done.

I watched the surgeon do that with child-like amazement. He's definitely a master of his craft.

I’m amazed by the surgery robot 😧 That panning with the camera made it look like a video game, very cool!

Tom, this was the coolest thing I've seen in weeks! Thanks! :)

My mom's surgeon practiced on 3d printed pieces like this before her shoulder replacement, it was really cool! The surgery went perfectly because of it.

This has got to be one of the most fascinating videos you’ve ever done. There’s so many different interconnected things going on!

"Let's open it up," is a great phrase to start a surgery.

This sort of thing is why i love science and engineering. 👍👍👍

Just for the people who want to know how it's printed. They have a special floating liquid where a printer arm goes in and 3D prints the tissue. The tissue is a special rubberized material that stays flexible even when 'hardended' They can easily inject fluids or blood into closed systems because the printer will then simply continue to close off the top sealing any liquid inside.

I wonder if doing this with a virtual model would be as effective. Imagine unlimited practice attempts on a specific patient before surgery without needing to create an actual 3D model.

That just blew my mind. As a frequent patient with a long list of medical issues I see the benefits of this. As noted every other profession has the ability to practice in exact circumstances, situations, playing fields, rehearsals, etc. Surgery is the only one where we’ve all said, “Well you operated on Fred and Martha, surely they are similar to me, have at it! This is brilliant, we’ll done folks.

I toured Lazarus 3D this summer with a group of teachers. They were so cool and so nice! If I didn’t love teaching so much I’d definitely apply there! They gave me a bit from a failed kidney print and I keep it on my desk 😂

I always knew that doctors in general and surgeons in specific had a lot of "talent" ... but wow seeing it really brings it home I am the type of person that will not watch medical things because im a little bit squemish ... but I can watch this and appreciate that levels of talent, learned skill, and practice that a surgeon has to put in to be able to do what they do

The surgeon was extremely well-spoken and helpful! I loved his explanations!

Wow, the 3D printed organs for practice are an amazing technology to go along with the already amazing robot assisted surgery!

That is awesome! Now I know one of the fields I should go into as a software engineering student.

Loved the intro to this. Always appreciate how clear you make it with things that may possibly influence the video.

Not able to endure staring at guts, but listened for entire 7 minutes cause I like Tom’s videos and the topic is interesting 😅

This is incredible technology! Additive manufacturing is such a powerful tool in so many fields that you wouldn't immediately expect to see it in. Great video Tom!

WOW, my jaw had a hard time staying closed this episode! What an amazing video and amazing feat of technology and medicine! Excited to see all the good this can do! Thanks for the video as always :)

That was fascinating. The next time I have to have any kind of major surgery I kind of want to spend some time with the surgeon and ask them if he's had the chance to practice on something similar. Might be an opportunity for me to educate the surgeon on something for a change.

This is going to save so, so, many peoples lives! This is really, truly amazing technology. It will allow surgeons to train as much as they need to in an almost-life accurate setting, that is completely customised to each individual patient, that will seriously improve the chances of the surgery being successful! This should really be the future...

This video was down right incredible! Thank you for sharing!

Doc using robotic arms as body language to explain things is hilarious 💀💀

Hope your recovery goes well Tom. 😆👍

I can't help but think of how absolutely beneficial this will be for those insanely complex surgeries that are once in a lifetime... like separating conjoined twins or delivering six babies or something. i mean, they do rehearse those things... but to physically practice it, and not just on a computer. Mindblowing!

hopefully more companies reach out to show off to you because we love it it's great and it's fun to watch new great things

That was the the most fascinating thing I've seen in months; maybe a year! Thanks!

What a time to be alive. This is amazing!

My god… soft 3d printing (with fluids inside) is very fascinating!

Omg imagine if they'd found an actual cyst or something and Tom's real surgeon could have a practice run at his real surgery

I love how you can see the surgeons little hand expressions through the robotic scalpels

Cheers for the emails, Tom, and for the incredibly interesting episodes

This was very interesting to see. 7 years ago I had a cancerous tumor removed from my right kidney along with half the kidney as well. The surgeon used the DaVinci robot as well. Always wondered how this all worked.

You could tell the Lazarus 3D rep is doing what he loves!

Oh my GOD words cannot describe how utterly *cool* this is.

There are people there who have fright of surgeries, to the point they might refuse to undergo one, but if they were told that a doctor specifically practiced the upcoming surgery, I feel like that could sway people to not opt out of a potential surgery.
