摘要：
A surgical instrument comprised of a stapling end effector having a staple-applying assembly with opposing stapling surfaces defining a closure distance therebetween, wherein at least one stapling surface is movable, and a handle connected to the stapling end effector and comprising a staple-firing assembly that causes the staple-applying assembly to staple tissue between the stapling surfaces. The handle further comprises a power source, electric motor, and closure assembly that has a drive part movable by the motor, detection mechanism, a controller. The drive part is connected to the stapling end effector. When the motor is supplied with power, the drive part advances the movable stapling surface towards the opposing stapling surface. The detection mechanism detects a position of the drive part along the drive-part axis and the controller is configured to prevent stapling unless the drive part is at a position corresponding to a closure distance within a pre-defined range.
