Abstract
An apparatus for operating on tissue comprises a handpiece, an elongate shaft, an end effector, a firing beam, and a modular motor. The end effector has a pair of jaws configured to open and close upon tissue. The firing beam comprises a blade insert with a sharp edge operable to sever tissue captured within the end effector. The modular motor is insertable into the handpiece. The modular motor comprises a drive gear that engages a plurality of components disposed within the handpiece. Rotation of the drive gear drives longitudinal translation of the firing beam within the elongate shaft. Longitudinal translation of the firing beam opens and closes the jaws of the end effector relative to tissue. Longitudinal translation of the firing beam also severs tissue captured between closed jaws of the end effector.
