Zusammenfassung:	A surgical apparatus comprises a body (220), a user input feature (228), a shaft assembly (230), an end effector, and a blade cooling system (270). The end effector comprises a clamp arm (244) and an ultrasonic blade (260) that may be coupled with an ultrasonic transducer. The clamp arm (244) is configured to pivot toward and away from the ultrasonic blade (260). The cooling system is operable to deliver liquid coolant to the ultrasonic blade to thereby cool the ultrasonic blade. The user input feature (228) is operable to both actuate the clamp arm (244) and actuate the cooling system. 本发明公开了种外科设备，所述外科设备包括主体(220)、用户输入特征结构(228)、轴组件(230)、端部执行器、和刀冷却系统(270)。所述端部执行器包括夹持臂(244)和可与超声换能器联接的超声刀(260)。所述夹持臂(244)被构造成能够朝向和远离所述超声刀(260)枢转。所述冷却系统能够操作以向所述超声刀递送液体冷却剂，以由此冷却所述超声刀。所述用户输入特征结构(228)能够操作以既致动所述夹持臂(244)又致动所述冷却系统。
