POWERED STAPLING DEVICE CONFIGURED TO ADJUST FORCE, ADVANCEMENT SPEED, AND OVERALL STROKE OF CUTTING MEMBER BASED ON SENSED PARAMETER OF FIRING OR CLAMPING

摘要

A surgical stapling instrument is disclosed. The surgical stapling instrument includes an end effector configured to clamp a tissue, a cutting member, a motor coupled to the cutting member, the motor configured to move the cutting member between a first position and a second position, and a control circuit coupled to the motor. The control circuit is configured to sense a parameter associated with clamping of the end effector or firing of the cutting member, or a combination of clamping of the end effector and firing of the cutting member, and control the motor to adjust a torque applied to the cutting member by the motor, a speed at which the motor drive the cutting member, or a distance to which the motor drives the cutting member according to the parameter, or any combination of adjusting the torque, the speed, and the distance.
