Powered surgical stapling device platform
First Claim
1. A powered surgical system comprising:
- a housing;
a battery disposed in the housing;
a motor coupled to the battery;
a flexible shaft extending distally from the housing and defining a first longitudinal axis;
an end effector disposed adjacent a distal portion of the flexible shaft, the end effector including a first jaw member and a second jaw member;
a flexible firing rod disposed within the flexible shaft and defining a second longitudinal axis, the flexible firing rod rotatable by the motor about the second longitudinal axis; and
a cam member disposed adjacent a distal portion of the flexible firing rod and having a pair of opposing camming surfaces, the cam member rotatable by the flexible firing rod such that one of the camming surfaces moves the first jaw member between a first position and a second position.

Abstract
The present disclosure provides for a surgical instrument which includes a housing and an endoscopic portion extending distally from the housing and defining a first longitudinal axis. The surgical instrument also includes an end effector disposed adjacent a distal portion of the endoscopic portion. The end effector includes an anvil assembly and a cartridge assembly. The anvil assembly is pivotally coupled to the cartridge assembly to be movable from a first actuation position to at least one other second actuation position. The surgical instrument further includes a firing rod having a shaft defining a second longitudinal axis, the shaft having a cam member which is in mechanical cooperation with the anvil assembly and is configured to move the anvil assembly from the first actuation position to the at least one other second actuation position upon rotation of the firing rod about the second longitudinal axis.
