Abstract
An ultrasonic surgical instrument includes a waveguide for transmitting ultrasonic energy, the distal end of the waveguide connected to a blade; a jaw member pivotable with respect to the blade; an inner tube sleeved on the waveguide; and an outer tube sleeved on the inner tube. The jaw member is pivotally connected to the distal end of the outer tube, the distal end of the inner tube acting on the jaw member, and the inner tube sliding with respect to the outer tube and driving the jaw member to pivot with respect to the blade. A first abutting portion provided on the distal ends of the inner tube and the outer tube forms a support between the inner and outer tube, so as to avoid a radial clearance change between the inner tube and the outer tubes without affecting the relative sliding movement of the inner and outer tubes.
