1. A surgical tool, comprising:
a drive housing;
a drive input rotatably mounted to a bottom of the drive housing;
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;
a static actuation limiter arranged within the drive housing; and
a dynamic actuation limiter provided by the capstan assembly and engageable with the static actuation limiter as the capstan assembly is actuated,
wherein engaging the dynamic actuation limiter against the static actuation limiter stops actuation of the capstan assembly.
