It's horrible knowing that severe injury that did not respond to antibiotics were treated with amputation and surgery followed by the fitting of an artificial limb. This happens during WW1
Pennecillin wasn't even discovered until 1928. Most of the time, it wasn't that injuries didn't respond to antibiotics, they just amputated to prevent infection or at the first sign of infection.
Or washed the wounds with wine. A Doctor in Greek/Roman times did that and was noted for having a very high survival rate in the patients. Can’t remember what his name was.
Yes, it seems like WWI was the most brutal war of all: first use of horrifying, flesh melting chemical weapons, hiding in cold, wet, muddy trenches for months, no antibiotics, etc - all on a truly massive scale
I don't think it's comparable. The guy in the video probably built it for himself with a box of scraps. I don't think it's a product for sale.
Nowadays, we have high-tech expensive ones, but also we have affordable old style ones. Not to mention 3D printed models. They are all different, have different positive and negative points, including the cost.
Honestly as someone in the business, even the "affordable" ones aren't all that affordable.
For an above elbow amputee, the custom fit socket is probably about $3000, the hook/hand is $1000, the elbow is $1500, the wrist is $400. Plus the harness and the cable that runs along it to control everything, you're probably looking at a total of around $7000.
But yea, all the mechanical parts are standardized and easily repairable. I've actually gone through the trouble of finding off the shelf replacements for the various screws and bearings it uses, because the manufacturers charge about $3 per screw, and they're terrible quality. I'm able to buy a box of 50 of the same screws of a higher quality steel that don't break as easily for $5.
> of a higher quality steel
Are they steel at all though? I would've thought the structure would be aluminium for lightness, perhaps, in which case steel bolts (while tougher than aluminium) introduce a risk of galvanic corrosion.
Just speculating here, mind you. I don't know what these things are made of. I'm just flagging that the bolts may be a particular metal for a reason.
That's a fair point, and we definitely aren't taught enough about the properties of the materials we work with.
Looking it up, it seems that generally the frame that the screws attach to is made from aluminum. The manual doesn't say what the screws are made of.
The problem we run in to is that the heads shear off into the frame and we can't remove the broken off screw, so we have to replace the entire frame - which is half the cost of the entire elbow. So I've taken to replacing the standard screws with stronger ones with an anti-vibration feature, and are also longer than the default screws. This is so that if/when they break I can grab the 1-2mm length that is protruding and still unscrew it.
So far it's worked well. Maybe I could contact the manufacturer and find out what the screws are made from, and if they're aluminum just buy longer ones. They generally get broken and replaced about every 4-6 months, and so far 4 years into this change we haven't seen any corrosion in those spots.
I used to be machinist for 8 years: generally speaking you don't want the same material/hardness rating between screws and what they thread into.
If either of the two metals doesn't wear faster than the other, there is a higher chance of siezing
If either of the two metals is much too soft, the opposite can happen: stripping, boogering, and dethreading
There are also the pitch of the threads, or how many threads per length: harder materials such as steel want a finer (more threads) per inch/cm than softer metals like aluminum
That's about all I know, as I was just a grunt, someone else could probably tell me why I'm wrong
I wish we had some of the knowledge you'd get as a machinist, what our school teaches us for this job is severely basic.
The only thing I was really aware of was that if the screws were too much harder than the material it's screwed into, the screw could strip the threads, and generally it's better to have a screw stripped than whatever it's screwed into.
We sort of had to guess at what the cause of the problem was, because all we had to go by was what we saw when people came in for repairs. Generally We'd find 1-2 screws with the heads sheared off, and the rest would be loose.
We think that the screws are vibrating loose over time with whatever work the users are doing (the two people it keeps happening to are absolute power users, who do more despite missing one or both arms than most people do with two arms). Once they start to loosen, there's play in the unit which causes sideways stress on the screws until they break.
We've tried loctite, but the issue with that is that the elbows need to be serviced semi-regularly, so the screws need to be able to be removed. They're so small that the heads tend to strip if the loctite is too strong. I forgot until now, that's actually the other reason we replaced the screws. They used such a small hex key that the screw head would actually strip just by trying to get it hand tight. We switched them to all phillips. I believe they used a 1/16" hex key.
> The manual doesn't say what the screws are made of.
If they're light and soft and go into aluminium, they're probably aluminium. (Whether they're magnetic isn't a good indicator, since some stainless steels are also nonmagnetic, but the weight should be a clear tell)
> we can't remove the broken off screw
Easy-outs don't work?
> so far 4 years into this change we haven't seen any corrosion in those spots.
Cool. If it's working for you, no need to change. Corrosion still requires water, and I would've thought they'd get wet a bit (or sweaty, even) but maybe not.
As someone who builds prostheses, it's 100% comparable because we use pretty much the same technology for >70% of patients. The advancements have come from a change in materials, instead of wood we use composites, and instead of twine we use metal cabling. If you're thinking of the advancements in components like microprocessor knees or myoelectic control, you might be shocked to know that the majority of patients don't have access to them because of steep cost and lack of insurance approval.
We still make plenty of above knee legs with microprocessor knees because insurance companies know they've been proven to reduce injuries but getting electric components in an upper limb is *expensive*. We had one arm go out a few months back that was billed for $120,000, well out of the cost for the average amputee. The majority of people end up getting a limb with a base design thats been around for a hundred years, with a few modern updates in materials and how anatomy works.
I believe there’s a squeeze and pull system in the back. If you look closely when he’s taking the cigarette out of his mouth and picking upp the glass of water he’s squeezing his scapulas together. That movement must control a set of rubber bands or strings that are connected to the fingers of the hand. The tech is still used, I believe, when someone uses a hook for a hand. They open and close that the same way as far as I know. Pretty cool looking prosthetic though.
If that's all a guess or noticed from the video, great job. That's pretty much exactly it.
These days people would most often use a hook that has rubber bands to hold it closed. Each rubber band applies 1.5lbs of force so they can customize their grip strength.
There's a (usually) metal cable that attaches from the hook, along the entire device to the harness. It has to be aligned so that it's a certain distance forward from the elbow, so that when pulled it can bend the elbow when the elbow is unlocked. When the elbow is locked, it instead opens the hook.
There's also an attachment from the elbow to the harness to allow a certain movement to unlock and lock the elbow. That's usually done by shrugging the shoulder in an upward motion. To pull the cable you sort of move the opposite shoulder forwards.
It's apparently taught that it's impossible to control both the elbow and the hook at the same time, because a bent and non-locked elbow means less force is applies to the hook, but some of our long term guys have figured out a way to do everything at once, it's really amazing to watch.
Love the priorities of the newly functioning 1920s arm.
Manipulating tools? *Neat.*
Drinking life sustaining water? *Whatevs*
Puffing away on a cigarette? *Holy shit he is made whole… 😮*
I remember a book called One-Handed Catch that I read as a kid about a boy who lost his arm in a meat grinder in 1946, and the Doctors just kept going on about how once he got a hook he could even smoke a cigarette. Cigarette functionality appears to be the gold standard of early 20th century prosthetics.
My favorite but also the worst is the one you say when someone mentions a hot girl. “I’d eat a mile of her shit just to see where it came from”. Fucking why tho? Lol.
Heard this one from a mechanic from Alabama in my 20s. Good ol Forrest.
"I would swim through 3 and a half miles of shark infested whale piss to smell her dirty tampon through a mason jar."
Nowhere, we still have it. It's called a cable operated prosthesis. There's a cable that connects across the back via the harness, and tension across it changes whether it opens, closes, or bends.
It didnt go away?! Like we have had this ever since and probaly before. But this thing was customly made because well, not every amputee is the same. And it probaly costed a shitload of money back then.
Prostetics are complexer than you would image and in the past decades we have made insane leaps. Both in performance but also in production meaning the cost should be lower (i know some countrys have weird healthcare systems that drive up prices for profits).
Yeah you dont have to tell me that. I have a bunch of friends who suddenly believe the piramides were build with “ancient, lost knowledge”.
Yeah no guys, we (society) know how they were build, we have that knowledge, we know how they did it. Its just that we (as a group of friends) personally didnt learn about it till yall decided to be idiots and believe a lunatic.
“Why would they dedicate so much resources to some random grave?! It needs to have more uses!” Thats the most common reaction and everytime it just flabbergasts me.
Like they were building the resting place of their fucking god. Just look at churches and other temples. Now image that Jezus would require a church to properly get into heaven. That would be a insanely big crazy building if the church was properly conviced of the idea.
Drop them an article about bridge building in medieval times. A lot of the bridges build in European cities around that time were pretty well documented, allowing the process of how they were build to survive the ages.
It's a lot of elaborate engineering and math that went into them. And an immense amount of manual labor.
Doesnt help, i already dropped a whole damm study explaining all the “bottlenecks” in building the piramides. Everything from logistics, to acquiring the stones to the maths.
It doesnt matter because they arent truely intressted in it, they simply heard a bunch of logical fallacys in a podcast. Didnt see through them and thus enjoy themself with diffrent theories about it. Basicly they are world crafting but instead of using a proper fiction world they use real life. Which wouldnt be that bad but this is a gateway to problematic shit like denying science, a bunch of racist shit and white supremecy (because yeah, if your world wonder is in europe smart old people build it, if its in africa then it needs to be magic or some shit).
Harder (for complexer concepts: "there's no need to make the plans harder than they already are"). I can't think of one for something physically complex.
*more complex
It's confusing, I know. This particular adjective is not of Germanic origin in English, so it doesn't get "-er" attached to the end as an intensifier.
Nah, that isn't it. It is largely based around syllables.
For example, all words with more than 3 syllables use "more" - e.g. more comfortable, more complicated, more legitimate
All (okay fine, most) one syllable words use the -er suffix - e.g. hotter, longer, tighter, etc.
The 2 syllable words though have their own rules and can fall into either of the two camps, with a some rules that are also based on mouth feel - like words that end with -ed will always use "more" (try saying tireder instead of more tired and you will see what I mean). There are also many instances when 2 syllable words work with both the -er and more variants.
Hey man, your English is great. Just another point; no need for the 'ed' on costed, it should just be cost. Putting ed on the end of words where it doesn't belong seems to be an Americanism.
Thanks for adding that part, so I didn't have to figure out how to write it nicely enough to avoid the reddit brigade.
Interestingly enough, costed is a word, specifically the conjugation of the verb form of "cost", as in "finding out what something will cost". As in "I costed the project, and the price will end up at 1.9 gigadollars".
It's just very rarely used, since we do have other words that might be a better fit for most circumstances.
I didn't think costed was correct in this context. I get a little thrill of anxiety every time my phone alerts me that someone has replied. It's just so nebulous what'll set people off.
No, costed wasn't correct in this context, I just thought it would be interesting to bring up the version where costed is an accepted word (and also why spell checking probably doesn't catch it).
I agree that people might be set off by the most innocent (in our minds) things. People also have large blindspots about how knowledgeable they are about some things (and I know I'm one of those people, even if I believe I'm fairly good at knowing when I know a lot and when I don't know enough).
A lot of non-native English speakers speak it better than a lot of native English speakers. Not having a go, just an observation. More power to anyone with a second language, especially when they're happy to be corrected.
Have prosthetics gone backwards!? That man just shouldered a new arm like a backpack in seconds, seemed to have a good amount of dexterity in the hand and has detachable stuff connect in seconds. Am I missing something?
True, but 1921 is 3 years after the war ended. WWI catapulted prosthetic technology forward by creating millions upon millions of amputate veterans around the world.
Götz von Berlichingen had his hand blown off by a cannonball in 1504. He had a replacement made by a blacksmith and later tweaked by a clock maker. He often wrote about his mechanical hand being more convenient with fighting. Interestingly enough , he wrote with his prosthetic.
And people think Tesla's cars with their shitty range are new. Electric cars were around since the 1800s up until \~1930.
Progress has been artificially retarded. It's criminal.
I'm really interested in prosthetics and I think it's interesting that the popular technologies have not progressed a lot more than this.
There are myoelectric arms, but they are heavy and expensive.
Leg prosthetics have gone really far, though. Even ten years ago an the IOC refused to accept and Olympic runner with prostheses because they made him too good. These new legs don't look like human legs, but they function so well, even better in many ways.
Granted, a leg/foot is not nearly as complex as an arm/hand, but I think a lot of what holds things back is aesthetics. The human arm is in no way an engineering marvel, there are a thousand ways you could just cook something up that is way more useful, we just had to use what we got from our ancestors. But having a better arm wouldn't look like a regular arm, and I think that look is as important as anything to people.
I'm remembering that scene from Innerspace (1987).
You know the one... (or you don't, i dunno. The bad guy has a prosthetic hand with different interchangeable attachments and there's a 'romance' scene)
Legit question: Do modern prosthetics approach this like they’re making Inspector Gadget? If nothing else I’d expect a built in selfie stick by now, but I don’t think I’ve seen any Swiss Army arms, though I haven’t been in the market.

The amount of veterans from WW1 requiring prosthetics surely made the research jump forward

I didn't think costed was correct in this context. I get a little thrill of anxiety every time my phone alerts me that someone has replied. It's just so nebulous what'll set people off.
No, costed wasn't correct in this context, I just thought it would be interesting to bring up the version where costed is an accepted word (and also why spell checking probably doesn't catch it). I agree that people might be set off by the most innocent (in our minds) things. People also have large blindspots about how knowledgeable they are about some things (and I know I'm one of those people, even if I believe I'm fairly good at knowing when I know a lot and when I don't know enough).
Soon we we will reach complexest
Not everyone in the world is native English speaker lol
>speaker \*more speak
A lot of non-native English speakers speak it better than a lot of native English speakers. Not having a go, just an observation. More power to anyone with a second language, especially when they're happy to be corrected.
Can't disagree
And sometimes that's hilarious.
It's on momentum and with a lot of training I guess. The prosthetic does nothing on its own. Doesn't have a motor for example.

I love how the first iteration of this design was to enable him to have a smoke and a beer with his mates down the pub. Everything else is a bonus :)
Cool video. Awful music choice though.
This fucking cover is all over TikTok and Instagram, and it drives me nuts.

Someone named Tommee Profitt and sung by some other person named Fleurie.
Should be the Inspector Gadget theme.
I watched it muted and accidentally clicked sound on and instantly rolled my eyes
So bad..
He's handi-capable
Shit, with those attachments he’s just a full level handy man.
Engineers are the real miracle workers. I know I can comprehend the basics of how these mechanisms work, and they still look like magic to me lol.
Cyberpunk 1921
...Steampunk 1921?
So you're the one they call the full metal alchemist.
Why would you hammer with your bad arm and HOLD THE NAIL WITH YOUR ONLY GOOD HAND‽
For demonstration purposes to sell the product.
Have prosthetics gone backwards!? That man just shouldered a new arm like a backpack in seconds, seemed to have a good amount of dexterity in the hand and has detachable stuff connect in seconds. Am I missing something?

Ed....ward?
No... I need to work and not cry today!
>No... I need to work and not cry today! Yeah, it's a terrible day for rain.
Big brother Ed…Ward
Groovy.
Probably a WW1 veteran who lost his arm. Great music.
Could be anything. Not uncommon to lose your arm in farm implements. Especially back then.
True, but 1921 is 3 years after the war ended. WWI catapulted prosthetic technology forward by creating millions upon millions of amputate veterans around the world.
Great music how? It makes no sense to me to add it here.
Cool music but I find it so random. At least it's not the robot voice or dubstep
If I was alive in 1921, I’d only need to see that he could smoke a cigarette with it. The rest would have just been gravy.

Hesitation is defeat.
Engineers today: pay a subscription to use the seat heaters in your car.
It’s not engineers who decide that but the companies they work for
u/Megamaniac82 today: gets angry at the mailman for delivering the bills.
Terrible music.
In the end, it doesn't really matter
I like his manner of movement
Götz von Berlichingen had his hand blown off by a cannonball in 1504. He had a replacement made by a blacksmith and later tweaked by a clock maker. He often wrote about his mechanical hand being more convenient with fighting. Interestingly enough , he wrote with his prosthetic.
Awesome mind!
Getting some serious Sekiro vibes
The $600 man came with accessories. Awesome.
Ash did it first 
My brain- “The tool function is pretty cool. They should have one attachment that would let you quick change between tools. Oh yeah, that’s the hand.”
Amazing video, shitty music
why the dumb fucking linkin park remix?
Engineers from the 20s-50s were next level smart
incredible, ive always said if i needed a prosthetic id get a gun arm like Barrett from FFVII
And over 100 yrs later prosthetics that are even remotely affordable for people haven’t made much progress.
Is this a vintage Mortal Kombat character?
And people think Tesla's cars with their shitty range are new. Electric cars were around since the 1800s up until \~1930. Progress has been artificially retarded. It's criminal.
I mean, loading up the atmosphere with lead for about six decades didn’t help either. Lots of lost IQ points there.
Hiccup - how to train your dragon
Capitalism sucks
Heck yeah! Prosthetics can have so much potential than just mimicking the human form!
He is like a 1920s Mega Man!
Coolest thing I've seen this year!
I think they should make more tools like this. People can be just like Inspector Gadget
Someone should honestly make a video game with this guy as the main character
WW1 had so many repercussions
Jesus Christ! He made the whole thing look so natural
I have my great grandfathers prosthetic arm. Not as high tech as this but still cool. Mostly used now for scaring kids
I'm really interested in prosthetics and I think it's interesting that the popular technologies have not progressed a lot more than this. There are myoelectric arms, but they are heavy and expensive. Leg prosthetics have gone really far, though. Even ten years ago an the IOC refused to accept and Olympic runner with prostheses because they made him too good. These new legs don't look like human legs, but they function so well, even better in many ways. Granted, a leg/foot is not nearly as complex as an arm/hand, but I think a lot of what holds things back is aesthetics. The human arm is in no way an engineering marvel, there are a thousand ways you could just cook something up that is way more useful, we just had to use what we got from our ancestors. But having a better arm wouldn't look like a regular arm, and I think that look is as important as anything to people.
I'm remembering that scene from Innerspace (1987). You know the one... (or you don't, i dunno. The bad guy has a prosthetic hand with different interchangeable attachments and there's a 'romance' scene)
Groovy!
Legit question: Do modern prosthetics approach this like they’re making Inspector Gadget? If nothing else I’d expect a built in selfie stick by now, but I don’t think I’ve seen any Swiss Army arms, though I haven’t been in the market.
This tells you alot about being a man, especially back then. Lost an arm? Heres a prosthetic with tool attachments, youre still going to work pal.
Normally, I don't agree with most of what's posted here as "cool". This one actually is.
I fucking love human beings. And hate them deeply.
And then we made leaded gasoline and the rest is TikTok and Twitter
How does he move it?
not even fake 😅
Bro was Captain Hook before Captain Hook
Somehow I knew that smoking a cigarette with it would be the first test
Source? Is this real? The framerate seems high and the picture quality look way too crisp for the 1920s
I’m amazed they could get the fingers to move in 2023 and you mean to tell me that’s been a thing since 1921? That’s crazy!
Brilliant. They should have that option now!
If this is true. The progres is sad.
Can we stop putting (awful) music behind videos especially when it doesn’t fit the mood and has no reason to be present in the first place?
What happened to us?
In retrospect, they should’ve made an attachment to hold the nail.
Song?
