A surgical instrument (100) including a housing (110), an endoscopic portion (140), a drive motor (200), a drive tube (210), a firing rod (220) and an end effector (160) 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. |
