  • Publication number: 20210259725
    Abstract: An ultrasonic surgical instrument and method of assembly with a predetermined alignment includes first and second modular assemblies and an electrical lockout. The first modular assembly includes at least a portion of an end effector configured to manipulate a tissue. The second modular assembly includes a transducer power circuit and an activation switch electrically connected to the transducer power circuit. The electrical lockout is electrically connected to the transducer power circuit and configured to inhibit the activation switch from powering the ultrasonic transducer with the first and second modular assemblies misaligned from the predetermined alignment such that the first and second modular assemblies are in a locked-out state. The electrical lockout is further configured to allow the activation switch to power the ultrasonic transducer with the first and second modular assemblies in the predetermined alignment such that the first and second modular assemblies are in an operational state.

  • Patent number: 10842517
    Abstract: A surgical instrument includes a body assembly, a shaft assembly that releasably attaches to the body assembly, and an end effector at a distal end of the shaft assembly. The body assembly includes a first support structure, a first electrical contact supported by the first support structure, and a first sealing surface. The shaft assembly includes a second support structure, a second electrical contact supported by the second support structure, and a second sealing surface.

    Abstract: Various systems and methods for determining the state of an end effector of an ultrasonic surgical instrument are disclosed. A control circuit can be configured to measure a complex impedance of an ultrasonic electromechanical system including an ultrasonic blade and compare the measured complex impedance to reference complex impedance patterns that each correspond to a state of the end effector. Accordingly, the control circuit can further be configured to determine the state of the end effector according to which of the plurality of reference complex impedance patterns the measured complex impedance corresponds.
