A surgical instrument (100) including a housing (110), an endoscopic portion (140), a drive motor, a drive tube, a firing rod and an end effector (160) is disclosed. The endoscopic portion (140) extends distally from the housing (110) and defines a first longitudinal axis (A-A). The drive motor is disposed at least partially within the housing (110). 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 (160) is disposed adjacent a distal portion (142) of the endoscopic portion (140) and is in mechanical cooperation with the firing rod so that the firing rod drives a surgical function of the end effector (160). |
