A handheld electromechanical surgical device, capable of effectuating a surgical procedure, includes a handle assembly having a power source; at least one motor coupled to the power source; and a controller configured to control the motor. The surgical device includes an adapter assembly having an electrical assembly having a proximal end in communication with the controller of the handle assembly. The surgical device includes a reload configured to selectively connect to a distal end of the adapter assembly. The reload includes an annular array of staples; an annular staple pusher for ejecting the staples; and a data storage device selectively connectable to a distal end of the electrical assembly. The data storage device receives and stores performance data of the surgical device from the controller of the handle assembly.

Handheld electromechanical surgical system

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. The surgical device further includes a surgical end effector configured to couple to the distal end portion of the adapter assembly.
