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.

Surgical instrument use indicator

Various ultrasonic instruments are disclosed. The ultrasonic instruments include an ultrasonic waveguide acoustically coupled to an ultrasonic transducer. Several techniques for acoustically coupling the ultrasonic transducer to the ultrasonic waveguide are disclosed.

Ultrasonic transducer to waveguide acoustic coupling, connections, and configurations

Aspects of the present disclosure include various ultrasonic surgical instruments. At least one disclosed surgical instrument includes a waveguide including a blade and a transducer base plate. The transducer base plate may be coupled to the waveguide to define a tapered joint at an interface between the waveguide and the transducer base plate. The transducer base plate may include first and second sides defining corresponding first and second flat faces configured to receive first and second piezoelectric elements. The first and second piezoelectric elements are configured to operate in a D31 mode.

Ultrasonic transducer to waveguide joining

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.

Electrical and thermal connections for ultrasonic transducer

A surgical instrument includes a shaft assembly and an end effector. The shaft assembly includes a shaft having a proximal end and a distal end. A lumen extends along at least a portion of the shaft. A lateral opening is formed in the shaft at a longitudinal position between the proximal and distal ends. The lateral opening is in fluid communication with the lumen. The shaft assembly further includes a movable member that is configured to selectively cover the opening. The end effector is at the distal end of the shaft. The lumen and the lateral opening may be used to flush debris and bodily fluids from the lumen and other regions of the shaft assembly.
