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.

[ Having thus described our invention, what we claim as new and desire to secure by Letters Patent is as follows:] [1.]1. A surgical instrument, comprising;means for preventing rotation of an output shaft, said preventing means being housed within a housing of the surgical instrument, said rotation preventing means including a locking switch slidable between a first position and a second position, said locking switch being lockable in said first portion and said second position by biasing a ball engaging with a first groove and a second groove of a drive housing associated with said housing, respectively, said ball being biased by a spring and said locking switch being non-rotatable;means for preventing failure of a motor shaft, said motor shaft driving said output shaft, said failure preventing means including:apertures positioned on said output shaft for holding contacting balls,a clutch plate having a plurality of detents, said contacting balls being contained substantially within said detents when a torque on said drive shaft is within a predetermined limit, said contacting balls disengaging from said detents and remaining within said apertures when said torque exceeds said predetermined limit; andmeans for mounting a battery pack to said housing, said mounting means including a retaining spring communicating with a groove of said housing.
