Abstract
A surgical instrument includes a handle assembly, a shaft assembly, an end effector and a clamp force sensor. The handle assembly includes a closure trigger that is pivotable between a released position and an actuated position. The end effector is coupled with the shaft assembly and includes a cartridge that includes an anvil and a cartridge housing. The cartridge housing is slidable with respect to the anvil between an unclamped position and a clamped position to facilitate selective clamping of patient tissue therebetween. The clamp force sensor is associated with the end effector and is configured to detect a clamping force between the anvil and the cartridge housing and facilitate generation of a notification as a function of the detected clamping force.
