Hey Krysztof! CAD engineer here. I can’t view the mp4 file. I understand the person cannot move their fingers, but you can move them with external help, right? The bottom line is this: WHY does the person want a device? is it for aesthetic purposes? is it both aesthetic and basic functionality? or do they want something that is purely functional and don’t care how it looks? It is very important to ask them first what exactly do they want to do with a device. There is no wrong answer, and every extra detail helps! Let me know if I can help with the design/mechanical work!

We just did one that was very similar,,, the kinetic worked perfectly.. see attached..

I agree, the Kinetic hand looks like a great option. I have made the kinetic for several recipients and they all are happy with the design.

she has a ‘surgically’ created pinkee on each hand ..

Kinetic Hand

Again, what do they want? There is a good chance even if the kinetic is useful, it might not help with what they need. Even if they need something crazy, we can figure out designs around that. There are many of our devices that \*could\* work, but that doesn't mean it's what they \*need\*.

Individual solutions for a particular application should not be ignored. I would expect that if a keen golfer lost his hand, there would be a solution available. Whether he wishes to spend $20,000 or look around for an alternative is up to himself. The dynamics of a golf swing is understood, although you may lose the distance it is unlikely that you will lose the accuracy. Well Ed Furgal did OK.

That I believe is the problem today. The emphasis should be on measurement , and std standard components, and the ability to adjust them to meet the particular requirements. It is not enough to provide a child in a third world country with a one off prosthetic limb, you need the ability to provide continual limbs as he or she grows up. The slicer, not the cad cam program can provide this solution, and the individual guy who 3d prints can provide the adjustment in size over the years. To be honest I reckon the school kids will provide a long term solution to any kid who requires this long term service

I don't think we are on the same page, so I'll try to fill in the blanks. What you are talking about is parametrization: having a couple parameters that can be adjusted so the device is regenerated accordingly (these can be size, width, length, diameter, printing offset, etc). This is something that is currently worked on, and I have already finished a Phoenix print-in-place that does just that, and should soon finish a normal Phoenix with even more params. HOWEVER. My position, and the position of every prosthetist I've ever had the pleasure of interacting with, is that we first need to know what the user WANTS, then see if our devices fill that need, or it should be a bespoke design. during my time with e-nable I’ve made a number of such designs, specific to each case, and I'm not the only engineer available for that either. Make use of us! Don't just try to do everything yourselves! That's what makes us a community!
