POWERED SURGICAL INSTRUMENT
A surgical instrument including a housing, an endoscopic portion, a drive motor, a drive tube, a firing rod and an end effector is disclosed. The endoscopic portion extends distally from the housing and defines a first longitudinal axis. The drive motor is disposed at least partially within the housing. The drive tube is disposed in mechanical cooperation with the drive motor and is rotatable about a drive tube axis extending through the drive tube. The firing rod is disposed in mechanical cooperation with the drive tube and at least a portion of the firing rod is translatable with respect to the drive tube. The end effector is disposed adjacent a distal portion of the endoscopic portion and is in mechanical cooperation with the firing rod so that the firing rod drives a surgical function of the end effector.
1 . A surgical instrument, comprising:
a housing;
an endoscopic portion extending distally from the housing and defining a first longitudinal axis;
a drive motor disposed at least partially within the housing;
a drive tube disposed in mechanical cooperation with the drive motor, the drive tube being rotatable about a drive tube axis extending therethrough;
a rod disposed in mechanical cooperation with the drive tube, at least a portion of the rod being translatable with respect to the drive tube; and
an end effector disposed adjacent a distal portion of the endoscopic portion, the end effector being in mechanical cooperation with the firing rod so that the firing rod drives a surgical function of the end effector.
