具有开关激活控制的手术器械
摘要：
手术器械包括壳体和可操作地联接至致动机构的细长轴，所述致动机构能够在已致动位置和未致动位置之间移动。端部执行器包括一对相对的第一钳口构件和第二钳口构件，并且适于连接至电外科能量源。开关能够在激活位置和释放位置之间移动，所述激活位置用于启动将电外科能量输送至端部执行器，所述释放位置用于终止将电外科能量输送至端部执行器。开关激活构件构造为在激活位置和释放位置之间移动开关。开关控制构件构造为在致动机构从已致动位置至未致动位置的至少一部分运动过程中将开关维持在激活位置中。
摘要（英）：

A surgical instrument includes a housing and an elongated shaft operably coupled to an actuating mechanism moveable between an actuated position and an unactuated position. An end effector includes a pair of opposing first and second jaw members and is adapted to connect to a source of electrosurgical energy. A switch is moveable between an activated position to initiate delivery of electrosurgical energy to the end effector and a deactivated position to terminate delivery of electrosurgical energy to the end effector. A switch activation member is configured to move the switch between an activated position and a deactivated position. A switch control member is configured to maintain the switch in the activated position during at least partial movement of the actuating mechanism from the actuated position to the unactuated position.
