Abstract
A surgical tool includes a drive housing defining an indicator aperture, a drive input rotatably coupled to a bottom of the drive housing, and an indicator assembly arranged within the drive housing and actuatable to provide visual indication that the surgical tool has exhausted its useful life. The indicator assembly includes a capstan assembly operatively coupled to the drive input such that rotation of the drive input correspondingly rotates the capstan assembly, an indicator mount secured to the drive housing, and an indicator shaft extending from the indicator mount along a longitudinal axis coaxially aligned with the indicator aperture. The capstan assembly is rotated with the drive input to actuate the indicator assembly between a non-activated state, where the indicator shaft is recessed into the indicator aperture, and an activated state, where the indicator shaft extends out of the drive housing via the indicator aperture to provide the visual indication.
