Abstract
A surgical instrument having a locking mechanism for preventing an output shaft of the surgical instrument from rotating and a further locking mechanism for mounting a battery pack to a distal end of a housing of the surgical instrument. The surgical instrument further includes a clutch mechanism for limiting the torque of a drive shaft of the surgical instrument. The locking mechanism for preventing the output shaft from rotating includes a locking switch which mates with a locking cap disposed on the output shaft. The locking mechanism for mounting the battery pack to the housing includes a groove at the distal end of the housing and a retaining ring which engages the groove when the battery pack is mounted on the housing. The clutch mechanism includes a clutch plate that interfaces with both the output shaft and the drive shaft and prevents failure of the motor shaft.
