ProDigits™

ProDigits™, short for Prosthetic Digits, are the self-contained fingers that are individually powered and controlled to provide new fingers for partial hand amputees.

Partial Hand Solution

Not having fingers or a thumb to act in opposition to one another makes simple tasks such as holding a fork or a cup difficult and frustrating. The ProDigits prosthesis gives renewed function and confidence by providing myoelectric control to each individually powered ProDigit or prosthetic finger. Now patients or users with between 1-5 missing fingers have a solution for what was once a highly debilitating condition.

There are physical criteria that dictate whether ProDigits are appropriate or not – candidates must have ‘Amputation at Transmetacarpal Level’ or higher of one or more fingers. It is possible to support candidates with a portion of the finger remaining, however, this does affect the aesthetics of the overall prosthesis.

Articulating Digits

The articulating digit underpins of the ProDigits partial hand provides the biggest benefit to the patient or user. With the ability to bend, touch, pick-up and point, and when used within an overall prosthesis, movements reflect the function of a natural hand. A unique stall feature allows patients or users to point single digits for typing, hand gestures or the use of a telephone – amongst other everyday tasks.

Prosthetic Build and Design

The modular nature of each ProDigit and the individually powered motor located within each digit means that the clinician can build a replacement prosthesis that is close to the patient or users missing anatomy. Solutions can be built to match the sound side or any remaining fingers. Thumb solutions can be built using either powered or non-powered options. Sockets are custom-designed and fabricated for each individual’s needs.

Take Control

ProDigits can be controlled via inputs from either FSR (Force Sensitive Resistor) or Remote Electrodes – either input option is chosen on the basis of either the signal site, the available space and patient or user preference. The control strategy is based on a traditional myoelectric regime, however, Touch Bionics has developed Bluetooth™ enabled solutions that mean the clinician can adjust the finer motor functions to the specific patient or user.
