摘要： A surgical instrument includes a rotatable electrical coupling assembly having a first part and a second part that electrically couple and rotate relative to each other. The second part is carried by and rotates with a tube collar coupled to a transducer. A portion of the transducer is inserted through an aperture of the second part, but does not contact the second part. The first part of the assembly may electrically couple to the second part via pogo pins, brush contacts, or ball bearings. Alternatively, the first part may comprise conductive channels formed in the casing. The second part may comprise a rotatable drum with a conductive trace. In some versions, one or more components may comprise MID components. In another version, the rotatable electrical coupling assembly comprises a rotatable PC board and brush contact. Further still, a circuit board may be provided with the transducer inside a transducer casing.

摘要： An ultrasonic surgical instrument includes a body, a shaft, an ultrasonic transducer, a waveguide, and an end effector coupled to a distal end of the shaft. A rotation knob is rotatably coupled to the body and is configured to rotate the shaft, the waveguide, and the end effector together relative to the body. A torque transfer structure is positioned radially outwardly of and in direct contact with the waveguide at an acoustic node thereof. The torque transfer structure is rotationally fixed relative to the waveguide and is configured to rotationally couple the waveguide with the shaft and the rotation knob. The waveguide includes a first axial constraining feature defining a distally facing surface, and the torque transfer structure includes a second axial constraining feature defining a proximally facing surface configured to abut the distally facing surface to constrain the waveguide axially relative to the torque transfer structure and the body.

摘要： An ultrasonic instrument includes a housing, an ultrasonic transducer support by the housing, and an integrated usage indicator. The housing is configured to removably connect to a shaft assembly. The ultrasonic transducer is configured to be acoustically connected to a waveguide and operated a predetermined number of use cycles. The integrated usage indicator is operatively connected to the housing and includes a used state indicator. The used state indicator is configured to indicate to a clinician in a used state when the ultrasonic transducer has been operated at least the predetermined number of use cycles for limiting usage of the ultrasonic transducer to the predetermined number of use cycles.

摘要： Disclosed is an ultrasonic surgical instrument comprising a transducer base plate, first and second piezoelectric elements positioned on opposite faces of the transducer base plate. The transducer base plate is coupled to a waveguide. The waveguide is electrically coupled to the first and second piezoelectric elements by a conductive adhesive. The first and second piezoelectric elements are electrically coupled to an ultrasonic signal generator through an electrode. A thermal conductor conducts thermal energy away from the first and second piezoelectric elements. Also disclosed is a method of fabricating such an ultrasonic surgical instrument.

摘要： A surgical instrument includes a shaft, an ultrasonic transducer, a waveguide, and an end effector at a distal end of the shaft. The end effector includes an ultrasonic blade acoustically coupled with the waveguide, a clamp arm movable relative to the ultrasonic blade, a first RF electrode provided by the clamp arm, and a second RF electrode provided by the ultrasonic blade. The first RF electrode is electrically coupled with a first RF electrical path of the instrument, and the second RF electrode is electrically coupled with a second RF electrical path of the instrument. The RF electrodes are operable to seal tissue with bipolar RF energy. An electrically insulative layer is provided on at least a portion of at least one of the ultrasonic blade, the waveguide, the shaft, or the clamp arm, and is configured to prevent shorting between the first and second RF electrical paths.

摘要： Systems, devices, and methods are operable to track usage of a surgical instrument and modify the performance of the surgical instrument based on the prior usage of the surgical instrument. Some surgical instruments are designed to have a limited service life beginning at their first use, or a limit to their overall usage in order to ensure safe use of the sensitive instruments. However, a lack of ability to track usage characteristics when the instrument is separated from an external power supply allows for user abuse and avoidance of such safety mechanisms. Adding a battery or capacitor to the instrument may allow for an ability to track usage when the instrument is separated from an external power supply. Implementing special user prompts, device use ratios, and device use half-life upon powering down of an instrument may additionally be used to prevent circumvention of safety features.

摘要： Ultrasonic surgical instruments including a handle housing, a switch frame, and a switch assembly are disclosed. The switch assembly may include a first switch arrangement movably supported on a distal portion of the handle housing and selectively movable relative to a first switch contact supported by the switch frame. The switch assembly may further include a second switch arrangement including a right switch button movably supported on a right side of the handle housing and selectively movable relative to a right switch contact supported by the switch frame, and a left switch button movably supported on a left side of the handle housing and selectively movable relative to a left switch contact supported by the switch frame. The first and second switch arrangements may be configured to be selectively actuatable by a single hand supporting the handle housing.
