Abstract
An instrument drive assembly includes a housing assembly and a coupling assembly. The housing assembly includes a drive assembly. The coupling assembly releasably couples an instrument drive shaft to a drive member of the drive assembly and an instrument sleeve of the surgical instrument to the housing assembly. Actuation of a retention mechanism of the coupling assembly between a locked and unlocked configuration couples and decouples the instrument sleeve of the surgical instrument therewith.
Claims21
An instrument drive assembly for use with a surgical instrument, the instrument drive assembly comprising:
- a housing assembly supporting a drive assembly therein;
- a coupling tube supported at a distal end of the housing assembly and extending distally therefrom;
- a coupling assembly supported on the coupling tube, the coupling assembly configured to releasably couple to an instrument drive shaft of the surgical instrument;
- a retention mechanism configured to releasably couple to an instrument sleeve of the surgical instrument;
- a drive screw defining a threaded portion;
- a drive nut threadingly engaged with the threaded portion of the drive screw such that longitudinal movement of the drive nut along a longitudinal axis of the drive screw results in rotation of the drive screw;
- and
- a drive member coupled to the drive nut and extending distally therefrom, wherein longitudinal translation of the drive member drives a function of the surgical instrument.
