    摘要： An ultrasonic surgical instrument comprises a shaft assembly including a waveguide, and an end effector arranged at a distal end of the shaft assembly and including an ultrasonic blade and a clamp arm. The instrument also comprises a base translatably coupled to shaft assembly. The base includes a first mechanical input and a second mechanical input. The instrument further comprises a closure actuation mechanism operatively connected between the first mechanical input and the clamp arm and configured to actuate the clamp arm from an open position toward a closed position upon selective drive of the first mechanical input. The instrument also includes an insertion actuation mechanism operatively connected between the second mechanical input and the shaft assembly and configured to actuate the shaft assembly from a proximal position toward a distal position upon selective drive of the second mechanical input for insertion of the end effector.

    摘要： A tool bit for an ultrasonic osteotome includes a bit body, an arbor fixed to the bit body, and a flat end portion fixed to the arbor. A toothed edge extends linearly along a length direction of an end portion of the tool bit, and recesses are distributed evenly on the toothed edge to form teeth spaced apart from each other. The toothed edge extends linearly along a length direction, and the cutting edges of teeth are distributed linearly, e.g., instead of having a sharp structure, thus will not scrape and hurt other tissues during cutting. Since the thickness of the cutting edge is the same as that of the back edge, when cutting bone tissues, the incision is wide, thus the end portion is not easy to be clamped by bone tissue, which effectively prevents the end portion from breaking and reduces occurrence chances of surgery accidents.
