Abstract
A surgical instrument. Various embodiments of the surgical instrument include an end effector comprising a firing member for acting on tissue positioned at the end effector. A rotatable drive shaft assembly may be connected to the end effector. A handle may be connected to the drive shaft assembly and may comprise a motor for actuating the drive shaft assembly and a firing trigger. A proportional run motor sensor may sense actuation of the firing trigger. When actuation of the firing trigger is sensed by the run motor sensor, the motor may be signaled to forward rotate to cause advancement of the firing member, and wherein a rate of rotation of the motor is proportionally related an amount of actuation of the firing trigger by a user of the instrument.

30. A surgical instrument comprising:
-
an end effector; a rotatable drive shaft assembly coupled to the end effector to actuate at least a portion of the end effector; a motor for actuating the drive shaft assembly; and a firing sensor positioned to be actuated by a clinician, wherein the firing sensor senses an amount of movement provided by the clinician; and a control circuit in electrical communication with the firing sensor and the motor, wherein the control circuit is configured to modify a rate of rotation of the motor based on an amount of movement of the of the firing sensor provided by the clinician. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37, 38, 39)
