A powered stapler configured to adjust the force, forward speed, and overall stroke of the cutting member based on the sensed parameters of the launch or clamp.

摘要

Surgical staple fasteners are disclosed. A surgical staple fastener is an end effector configured to clamp tissue, a cutting member, and a motor connected to the cutting member, with the cutting member between a first position and a second position. Includes a motor configured to move in and a control circuit connected to the motor. The control circuit senses the parameters associated with the firing of the end effector clamp or cutting member, or the combination of the end effector clamp and cutting member firing, and the torque applied to the cutting member by the motor, the motor is the cutting member. The motor is configured to control the speed at which the motor is driven, or the distance at which the motor drives the cutting member according to parameters, or any combination that adjusts the torque, speed, and distance.
