In 2013, we began developing a functional prosthesis for partial truncation of the hand in a federal prosthesis institute. During that time, for patients with partial truncations or undeveloped hands in Russia, only cosmetic prostheses were manufactured. We saw 3D prostheses appearing at that time for children and we understood that such constructions could be applied only during childhood due to the fragility of the construction and commonality with toys.
We started developing a universal system of components for most partial truncation options and incomplete hand development. Work was conducted at the engineer and doctor levels, backed up by many trials and tests within the bounds of dissertation research. At this time, the work has been completed and a manufacturing package for the hand’s active prosthesis with assembly instructions is ready for sale.
Features of active hand prosthesis:
-
- lying at the foundation of the prosthesis is an active phalange module of the finger;
- the artificial phalange fingers are covered by silicon cosmetic pads;
- the thumb has acquired a fillet for the first time in its class, passively regulating the resistance angle, for realignment of grip;
- a technical prosthesis filling is placed in the carrying socket wall, which makes prosthesis lengthier;
- the appearance of the prosthesis can be both as anthropomorphic and futuristic as possible, according to the patient’s desires;
- a silicon insertion prosthetic socket for as sturdy and comfortable attachment as possible;
