摘要： An electrosurgical device comprises a body, an end effector, a cutting member, and a shaft. The end effector includes a pair of jaws that are operable to deliver RF energy to tissue that is clamped between the jaws. The cutting member is operable to sever tissue that is clamped between the jaws. The shaft extends between the body and the end effector. The shaft includes an articulation section that is operable to selectively position the end effector at non-parallel positions relative to the longitudinal axis of the shaft. Some versions include a rotation section that is distal to the articulation section. The rotation section is operable to rotate the end effector relative to the articulation section.

摘要： The surgical instrument may be operated in a first operating mode in which a transducer of the surgical instrument produces mechanical energy, or vibrations, that are transmitted to the end effector and a second operating mode in which electrical energy, or current, can flow through the end effector to perform electrosurgery. The surgical instrument may comprise a clamp, or jaw, which can be moved into a closed position to hold tissue against a waveguide, or blade, of the end effector. In the second operating mode of the surgical instrument, current can flow from a power source, through the waveguide, and return to the power source through a path comprising the jaw. The surgical instrument comprises an ultrasonic generator module. An electronic circuit is coupled to the ultrasonic generator module to monitor an electrical characteristic of the ultrasonic drive system.

摘要： In one general aspect, various embodiments are directed to a surgical instrument that can supply mechanical energy and electrical energy to an end effector of the surgical instrument. The surgical instrument may be operated in a first operating mode in which a transducer of the surgical instrument produces mechanical energy, or vibrations, that are transmitted to the end effector and a second operating mode in which electrical energy, or current, can flow through the end effector to perform electrosurgery. In another general aspect, the surgical instrument may comprise a clamp, or jaw, which can be moved into a closed position to hold tissue against a waveguide, or blade, of the end effector. In the second operating mode of the surgical instrument, current can flow from a power source, through the waveguide, and return to the power source through a path comprising the jaw. In one general aspect, various embodiments are directed to an ultrasonic surgical instrument that comprises a handpiece housing that operably supports an electrical contact assembly therein that is in electrical communication with a signal source. An acoustic assembly is supported within the handpiece housing in rotatable contact with the electrical contact assembly. In various embodiments, the signal source produces at least one of an ultrasonic signal and a radio frequency signal. In one general aspect, various embodiments are directed to a surgical instrument that can supply mechanical energy and electrical energy to an end effector of the surgical instrument. The surgical instrument comprises an ultrasonic generator module coupled to an ultrasonic drive system, which comprises an ultrasonic transducer coupled to a waveguide and an end effector coupled to the waveguide. The ultrasonic drive system is configured to resonate mechanically at a resonant frequency to generate a first ultrasonic drive signal. An electronic circuit is coupled to the ultrasonic generator module to monitor an electrical characteristic of the ultrasonic drive system. A processor is coupled to the electronic circuit to control the ultrasonic drive signal in response to the monitored electrical characteristic of the ultrasonic drive system.
摘要翻译：在一个一般方面，各种实施例涉及可以向外科器械的末端执行器提供机械能和电能的手术器械。外科器械可以在第一操作模式中操作，其中手术器械的换能器产生传递到末端执行器的机械能或振动，并且第二操作模式，其中电能或电流可以流经末端执行器执行电外科手术。在另一个一般方面，外科器械可以包括夹子或钳口，其可以移动到关闭位置以将组织保持抵靠末端执行器的波导或刀片。在手术器械的第二操作模式中，电流可以从电源流过波导，并且通过包括钳口的路径返回到电源。在一个一般方面，各种实施例涉及一种超声外科器械，其包括可手动地支撑其中与电信号源电连通的电触头组件的手机壳体。声学组件被支撑在手持壳体内，与电接触组件可旋转接触。在各种实施例中，信号源产生超声波信号和射频信号中的至少一个。在一个一般方面，各种实施例涉及可以向外科器械的末端执行器提供机械能和电能的手术器械。外科器械包括耦合到超声波驱动系统的超声发生器模块，该超声波发生器模块包括耦合到波导的超声波换能器和耦合到波导的端部执行器。超声波驱动系统被配置为以共振频率机械谐振以产生第一超声波驱动信号。电子电路耦合到超声波发生器模块以监测超声波驱动系统的电特性。处理器耦合到电子电路以响应于超声波驱动系统的监测电特性来控制超声波驱动信号。
