    摘要： A surgical stapler includes first and second elongate members, a clamp member, and a firing assembly. The second elongate member is configured to receive a staple cartridge. The clamp member is operable to releasably clamp the first elongate member against the second elongate member. The firing assembly is translatable to fire the staple cartridge. The firing assembly includes a slider and an actuator configured to be selectively actuated by a user. The slider includes inner and outer engagement features. The actuator includes inner and outer engagement features. The inner engagement feature of the actuator is configured to engage with the inner engagement feature of the slider at a first interface when the actuator moves relative to the slider. The outer engagement feature of the actuator is configured to engage the outer engagement feature of the slider at a second interface when the actuator moves relative to the slider.

    摘要： A surgical clip applier comprising an electric motor system is disclosed. The electric motor system is configured to drive a clip firing system of the surgical clip applier. The surgical clip applier further comprises a control system configured to control the electric motor system. The control system is configured to monitor a strain gauge circuit to assess the crimping force experienced by the clip firing system. In at least one instance, one or more strain gauges (71720, 71730) are mounted to a drive shaft and/or jaw (71700) of the clip firing system. The control system modifies the operation of the surgical clip applier when the voltage of the strain gauge circuit exceeds and/or falls below a threshold. In at least one instance, the control system modulates the width, or duration, of voltage pulses applied to the electric motor system to control the speed of the electric motor system.
