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.

An ultrasonic surgical instrument includes a body such as a handle assembly and an acoustic transmission assembly. The acoustic transmission assembly includes an ultrasonic transducer and an end effector. A mounting ring is positioned on a horn of the transducer. A rotatable drum is positioned distal to the mounting ring. Piezoelectric components of the transducer are positioned proximal to the mounting ring. Electrical conduits extend from the drum to the piezoelectric components and are routed over or through the mounting ring. The drum is coupled with a power source through a slip ring assembly to selectively activate the transducer.

A surgical instrument includes an ultrasonic transducer, a body, and a transducer carrier assembly. The ultrasonic transducer is operable to deliver energy through the surgical instrument to a surgical site. The body is operable to house the ultrasonic transducer. The transducer carrier assembly is in communication with the body and the ultrasonic transducer. The transducer carrier assembly is operable to enable the translation and/or the rotation of the ultrasonic transducer within the body.

In one general aspect, various embodiments are directed to methods for treating tissue within an aqueous environment. Various methods may include introducing a cutting implement of a surgical instrument into the aqueous environment. The cutting implement may have at least one cutting surface thereon and at least one ultrasonic portion thereon and be selectively rotatable within a hollow sheath. The methods may include rotating or rotatably oscillating the cutting implement within the hollow sheath for tissue cutting purposes. The cutting implement may also be retained in a position wherein the ultrasonic portion of the cutting implement may be applied to tissue and then have ultrasonic motion applied thereto.

In one general aspect, various embodiments are directed to an ultrasonic surgical instrument that comprises a handpiece housing that rotatably supports an ultrasonic transducer assembly therein that may be selectively rotated by various motor configurations. Various slip ring arrangements are disclosed for supplying ultrasonic electrical signals and motor drive signals from a control system. Various forms of blade and cutting implements are disclosed for attachment to the ultrasonic transducer assembly such that such implements may be selectively rotatable within a hollow outer sheath. Vacuum may be applied to the cutting implement or through the outer sheath to draw tissue through an opening in the sheath and into contact with the cutting implement.

摘要:
An ultrasonic surgical instrument includes a reusable handle assembly and a removable and disposable transmission assembly. The handle assembly includes a trigger, a housing having a distal aperture formed in a distal end of the housing, a button disposed on a top surface of the housing, and a biasing member in communication with the button. The transmission assembly includes a proximal shaft, a rotator knob having a coupling feature, a distal shaft assembly extending distally from the proximal shaft, and an end effector at the distal end of the distal shaft assembly. The biasing member of the handle assembly is adjustably coupled to the coupling feature of the transmission assembly. Another version includes a movable yoke configured to engage an inner tube of the transmission assembly. Yet another version includes a waveguide of the transmission assembly non-threadably coupled to a transducer via a biasing force.
