An ultrasonic surgical instrument includes a body, an ultrasonic supported by the body, a shaft extending distally from the body and defining a shaft axis, a waveguide extending distally through the shaft, and an end effector arranged at a distal end of the shaft. The end effector includes an ultrasonic blade coupled to a distal end of the waveguide and having a primary blade treatment surface configured to treat tissue, and a clamp arm coupled to the distal end of the shaft. The shaft and the waveguide are selectively rotatable relative to one another about the shaft axis through a predefined range of angular motion between an assembly state and an operational state. In the assembly state, the clamp arm and the primary blade treatment surface are rotationally offset from one another. In the operational state, the clamp arm and the primary blade treatment surface are rotationally aligned.

Ultrasonic surgical instrument with pre-assembled acoustic assembly

A surgical instrument includes a shaft assembly, a handle assembly, and a latch system configured to operatively couple the shaft and handle assemblies. The latch system includes shaft and a handle lock members respectively connected to the shaft and handle assemblies for inhibiting operative uncoupling of the shaft and handle assemblies. The latch member has a cam surface and a latch member. The latch member is configured to selectively move from a locked position to a released position such that movement of the latch member causes the shaft and handle lock members to disengage and uncouple the shaft and handle assemblies. The latch member is further configured to selectively move from the released position to a removal position such that further movement of the latch member causes the cam surface of the latch member to engage the cam base and urge the shaft assembly in a removal direction.
