KAS Finger Prosthesis

Title: KAS Finger Prosthesis: Restore Grip Strength and Functionality

Description: The KAS finger prosthesis harnesses residual muscle strength, utilizing a combination of stainless steel levers for powerful, intuitive control. Securely mounted on the back of the hand, the prosthesis provides fingertip force proportional to the user’s effort; a typical male user can achieve 3-4.5 kg of force at each fingertip. A unique hook-grip posture allows for lifting significantly heavier objects by effectively transferring the load to a wrist-mounted suspension. Powered by the intact MCP joint, the prosthesis requires sufficient remaining tissue for secure ring fixation. Even amputees not meeting these minimum requirements can benefit from the device’s functionality, although individual considerations should be discussed prior to ordering.
