    • An ultrasonic dissection and coagulation system for surgical use is provided. The system includes an ultrasonic instrument, a control module, and a pedal actuator. The ultrasonic actuator has a housing and an elongated body portion extending from the housing. An ultrasonic transducer supported within the housing is operatively connected to a cutting blade by a vibration coupler. The vibration coupler conducts high frequency vibration from the ultrasonic transducer to the cutting blade. The cutting blade has a cutting surface which is angled with respect to the longitudinal axis of the elongated body portion and, thus, with respect to the axis of vibration. A clamp member having a tissue contact surface is positioned adjacent to the blade member and is movable from an open position in which the tissue contact surface is spaced form the cutting surface to a clamped position in which the tissue contact surface is in close juxtaposed alignment with the cutting surface to clamp tissue therebetween. The clamp member and the angled blade combine to enhance contact between tissue and the cutting surface of the blade member.
    • 提供了一种外科用超声波解剖和凝血系统。 该系统包括超声波仪器,控制模块和踏板致动器。 超声波致动器具有壳体和从壳体延伸的细长主体部分。 支撑在壳体内的超声换能器通过振动耦合器可操作地连接到切割刀片。 振动耦合器将高频振动从超声波传感器传导到切割刀片。 切割刀片具有相对于细长主体部分的纵向轴线成角度并且因此相对于振动轴线成角度的切割表面。 具有组织接触表面的夹紧构件定位成与刀片构件相邻,并且可从其中组织接触表面从切割表面间隔开的打开位置移动到夹紧位置,在该夹紧位置中,组织接触表面与 切割表面以夹紧组织。 夹紧构件和成角度的刀片组合以增强组织与刀片构件的切割表面之间的接触。
