Functional hand prostheses with traction control - control of grip force and speed

Features of a functional prosthesis with traction control

Functional upper limb prostheses with traction control — this is a modern solution for people with amputees who seek to restore not only aesthetics, but also active hand function. Such prostheses allow the user to fully control the movements and grip strength, using the natural movements of the shoulder girdle.

Easy to learn: the user quickly gets used to controlling the prosthesis using the rods.
Control of force and speed: during the grip, the user determines the force and speed of movement.
Feeling of resistance: the prosthesis allows you to feel contact with an object, which significantly improves functionality.
Driven by shoulder girdle movements: no electronic mechanisms — everything works mechanically and reliably.
Reliability and durability: prostheses with traction control are less susceptible to damage, easy to maintain.

A functional prosthesis consists of

A stump-receiving sleeve — provides reliable fixation on the stump.
A traction system — a mechanism that transmits the movements of the shoulder girdle to the prosthesis.
A prosthetic hand or forceps — performs the grip and working functions of the hand.
Cosmetic shell (optional) — for a natural look and comfort.

This type of prosthesis allows you to perform many everyday activities: holding a cup, pen, small object, writing or using tools.

Frequently asked questions about functional traction-controlled prosthesis

This is a mechanical arm prosthesis that is powered by movements of the shoulder girdle through a system of rods. The user controls the force, speed, and direction of the grip.

A functional prosthesis allows you to perform active actions — hold objects, control your grip, and feel resistance. A cosmetic prosthesis is intended for aesthetics only.

The user moves the shoulder girdle, which, through a system of rods, transmits movements to the hand or forceps of the prosthesis. The user's effort determines the strength and speed of the grip.

Yes. The main advantage is ease of use and intuitive control, without complex mechanisms and electronics.

Hold light and medium objects, perform simple manipulations, write, use cutlery or tools.

Yes. The pull system conveys the feeling of contact with the object, which allows for better grip control.

For people with upper limb amputations who want to fully restore active hand functions and control movements with their own efforts.

Mechanical prostheses are reliable and easy to maintain. It is necessary to periodically check the traction system and the sleeve, avoid heavy contamination and impacts.
