The endoscopic portion (140) extends distally from the housing (110) and defines a first longitudinal axis. The drive motor (200) is disposed at least partially within the housing (110). The drive tube (210) is disposed in mechanical cooperation with the drive motor (200) and is rotatable about a drive tube (210) axis extending through the drive tube (210). The firing rod (220) is disposed in mechanical cooperation 10 with the drive tube (210) and at least a portion of the firing rod (220) is translatable with respect to the drive tube (210). The end effector (160) is disposed adjacent a distal portion of the endoscopic portion (140) and is in mechanical cooperation with the firing rod (220) so that the firing rod (220) drives a surgical function of the end effector (160).1/8 cCo CD ；IcczV
