Cable retainment features for cable-actuated surgical tools

Abstract

A surgical tool includes a drive housing, a drive input rotatably mounted to a bottom of the drive housing, and a capstan assembly arranged within the drive housing and operatively coupled to the drive input such that rotation of the drive input correspondingly actuates the capstan assembly. The capstan assembly includes a capstan that provides a cable pulley with a pulley groove sized to receive a drive cable wrapped at least partially about the capstan, a crimp pocket defined in the cable pulley and sized to receive a termination crimp secured to an end of the drive cable, and a cable retainment feature provided on the cable pulley and operable to retain the termination crimp within the crimp pocket once received therein. The termination crimp is received within the crimp pocket by forcing the termination crimp past the cable retainment feature.
