摘要：
An ultrasonic surgical instrument includes a transmission assembly extending from a body assembly that is configured to selectively couple to a disposable clamp arm. In some versions the clamp arm may include a tab that is insertable into a slot of an inner member such that actuation of the inner member rotates the clamp arm relative to a blade. In other versions the clamp arm may include a ball recess and the inner member may include a rod and ball. The clamp arm may be configured to snap onto the ball and rod. Alternatively, the clamp arm may include living hinges coupleable to an outer sheath and the inner member. Such living hinges may be unitarily formed with a clamp pad on the clamp arm. Further still, the clamp arm may be part of an end effector configured to couple to the transmission assembly via resilient tabs and slots.
