Abstract

Features for prosthetic digits are described. The digits mimic natural fingers by having multiple articulating segments, for example three, that can rotate varying amounts. Rotatable and / or linearly expandable mechanical links are configured to provide the digit segments with multiple degrees of rotational freedom. The digit may have an actuator that outputs linear actuation to cause rotation of the digit segments. The digit may have an expandable proximal link to allow for variable relative rotational positions of the segments. Middle and / or distal digit segments may fully rotate independent of rotation of a proximal digit segment. The rotated digit may thus fully surround and grasp small or large objects, objects with irregular outer contours, etc.

Description

technical field [0001] The characteristics of the prosthesis, especially the prosthetic fingers, are described. Background technique [0002] Prosthetic fingers are useful for amputees who have lost their natural fingers. Existing prosthetic finger solutions do not adequately mimic natural fingers and therefore cannot fully restore function. Accordingly, improvements to prosthetic fingers are desired. Contents of the invention [0003] The implementations disclosed herein each have several aspects, no single one of which is solely responsible for the desirable attributes of the present disclosure. Without limiting the scope of the present disclosure, its more salient features will now be briefly discussed. After considering this discussion, and particularly after reading the section entitled "Detailed Description of Embodiments," one will understand how the features of the embodiments described herein provide advantages over existing systems, devices, and devices for pr...
