Abstract
A surgical device includes a power source, a motor coupled to the power source, and a transmission assembly movable by the motor. The device also includes a reload coupled to the transmission assembly. The reload includes a plurality of staples ejectable by the transmission assembly. The device further includes a distance sensor configured to monitor operation of the transmission assembly and output distance data. The device additionally includes a controller configured to operate the motor to move the transmission assembly proximally from a distal position until a hard stop is reached, and determine whether the plurality of staples have been previously ejected based on the distance data.
