    Abstract: 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.

  • Patent number: 11744636
    Abstract: A surgical system comprising a generator and a surgical instrument configured to receive power from the generator is disclosed. The surgical instrument comprises a housing, a shaft defining a longitudinal axis, an end effector, and an internal charge accumulator. The housing comprises a motor. The end effector is operably responsive to actuations from the electric motor, transitionable between an open and closed configuration, and rotatable about an articulation axis transverse to the longitudinal axis. The generator is incapable of supplying a sufficient power directly to the motor to perform the actuations. The internal charge accumulator is in electric communication with the generator and supplies power to the motor. The internal charge accumulator is chargeable by the generator to a threshold value at a charge rate dependent on a charge level of the internal charge accumulator. The charge rate is independent of a charge expenditure by the surgical instrument.
