Abstract
A surgical device includes a handle assembly having a power source, a motor coupled to the power source, and a controller configured to control the motor. The device also includes an adapter assembly configured to selectively couple to the handle assembly, the adapter assembly including a stapling transmission assembly movable by the motor. The device also includes a reload configured to selectively couple to a distal portion of the adapter assembly, the reload including a plurality of staples ejectable from the reload by the stapling transmission assembly. The device also includes an anvil assembly selectively couplable to the distal portion of the adapter assembly, the anvil assembly being movable relative to the reload, where the controller may be further configured to control the motor to move the stapling transmission assembly to eject the staples while compensating for mechanical losses of the stapling transmission assembly.
