摘要：
A surgical instrument includes a housing, a movable handle, a trigger, a drive assembly operably coupled between the movable handle and an end effector assembly such that movement of the movable handle from an initial position to a compressed position manipulates the end effector assembly, and a linkage operably coupled between the trigger and a knife such that movement of the trigger from an un-actuated position to an actuated position rotates the linkage to deploy the knife relative to the end effector assembly. A drive housing of the drive assembly inhibits rotation of the linkage when the movable handle is disposed in the initial position and the trigger is disposed in the un-actuated position. The drive housing cams along a surface of the linkage to urge the linkage to rotate when the movable handle is returned towards the initial position, thereby returning the trigger towards the un-actuated position.
