Abstract: Surgical instruments include a first drive assembly having a first drive gear and a lockout mechanism positioned for releasable engagement with the first drive assembly to inhibit rotation of the first drive gear. The lockout mechanism includes a pawl and an actuator means for moving the pawl from a first position in engagement with the first drive gear to a second position spaced from the first drive gear.

Abstract: A surgical device includes a handle assembly having a controller and an adapter assembly including a tubular housing having a proximal end portion configured to couple to the handle assembly and a distal end portion. The adapter assembly also includes a load sensing assembly disposed with the tubular housing. The load sensing assembly is configured to measure a load exerted on the tubular housing and includes: a sensor body having a pocket defined therein; a load sensor circuit disposed within the pocket and coupled to the sensor body; and a signal processing circuit disposed within the pocket and electrically coupled to the load sensor circuit. The load sensing assembly further includes a cover disposed over the pocket and enclosing the load sensor circuit and the signal processing circuit therein, the cover being coupled to the sensor body thereby forming a first hermetic seal therebetween.
