Surgical device having multiple drivers
First Claim
1. A surgical device comprising:
- a jaw portion having a first jaw and a second jaw;
a shaft assembly coupled to a proximal end of the jaw portion, the shaft assembly defining a longitudinal axis;
a handle assembly supporting the jaw assembly; and
a drive assembly supported in the handle assembly, the drive assembly being configured to apply a plurality of control motions to the shaft assembly;
wherein the drive assembly includes a gear train operably communicating with a firing input bevel gear for actuating at least one gear of the gear train to transversely communicate with at least one other gear of the gear train; and
wherein the gear train includes a first bevel gear and a second bevel gear, the first and second bevel gears being coaxial with the longitudinal axis defined by the shaft assembly.

Abstract
A surgical device is provided, the surgical device including a first driver for performing a first movement function; a second driver for performing a second movement function; a first rotatable drive shaft configured, upon actuation, to cause selective engagement of one of the first and second drivers with a second rotatable drive shaft, wherein the second rotatable drive shaft is configured to drive the selectively engaged one of the first and second drivers. Third and fourth drivers may also be included. The drivers may function to rotate a shaft portion of the surgical device relative to, and about the longitudinal axis of, a handle; move a jaw portion relative to the shaft portion; move a first jaw relative to a second jaw; and/or move a surgical member within the second jaw.
