Ultrasonic surgical instrument having a handle assembly, a waveguide extending distally from handle assembly, an end-effector at distal end of the waveguide, and a clamp assembly removably mounted to the handle assembly. The clamp assembly includes a pivotally mounted clamp arm for pivotal movement with respect to the end effector, and is removably mounted to the handle assembly by axially aligned first and second bayonet mounts. Each of the bayonet mounts includes a female bayonet coupling having at least one bayonet slot configured to matingly receive a bayonet mounting pin of a male bayonet coupling, wherein the bayonet slots extend circumferentially about the longitudinal axis of the waveguide. A method of removing the clamp assembly of the ultrasonic surgical instrument is also provided, as well as an ultrasonic surgical shears instrument and a clamp assembly.

Ultrasonic surgical instrument

An engagement detection system ('EDS') adapted to be positioned between, and in electrical communication with, an electrosurgical generator and an electrosurgical instrument. The EDS adapted to electronically detect that the electrosurgical instrument is inserted into a trocar cannula, and thereafter deliver electrosurgical energy to the instrument. A method of operating an endoscopic electrosurgical instrument inserted into a trocar cannula, as well as a switch assembly are also provided.

Electrosurgical systems and methods

A modular signal interface system for providing electrical communication with a surgical instrument when the surgical instrument is inserted into a cannula of a trocar. The system includes a signal interface adapter and an instrument connector. The signal interface adapter is provided on, or adapted to be mounted on a trocar, and includes central aperture extending therethrough and a proximal face having a plurality of conductive contacts. The instrument connector is provided on or adapted to be mounted on a shaft of a surgical instrument, and includes a central aperture extending therethrough and a distal face having a plurality of conductive contacts. The signal interface adapter and the instrument connector are adapted for mating engagement such that, when matingly engaged, their central apertures are axially aligned and predetermined ones of the plurality of contacts of the signal interface adapter are in conductive contact with predetermined ones of the plurality of contacts of the instrument connector.

Modular signal interface system and powered trocar

An ultrasonic surgical device including an elongate waveguide having a longitudinal axis and a distal end, and a blade extending away from the distal end of the waveguide, the blade including a curved portion that includes first and second opposed faces extending lengthwise along at least a portion of the length of the blade. Each of the first and second faces has a width that extends perpendicular to the longitudinal axis of the waveguide and a length that extends orthogonal to the width. A pair of hook portions are located on opposite sides of the blade. A method of fabricating an ultrasonic surgical device is also provided.

Double hook ultrasonic surgical blade

An ultrasonic surgical instrument having a handle assembly, a waveguide extending distally from the handle assembly, an end-effector located at a distal end of the waveguide, and a clamp assembly removably mounted to the handle assembly, the clamp assembly including a clamp arm pivotally mounted on the distal end of the clamp assembly for pivotal movement with respect to the end effector. The clamp assembly is removably mounted to the handle assembly by axially aligned first and second bayonet mounts, each of the bayonet mounts including a female bayonet coupling having at least one bayonet slot configured to matingly receive a bayonet mounting pin of a male bayonet coupling therein, wherein the bayonet slots extend circumferentially about a common longitudinal axis corresponding to the longitudinal axis of the waveguide. A method of removing the clamp assembly of the ultrasonic surgical instrument is also provided, as well as an ultrasonic surgical shears instrument and a clamp assembly are also provided.

An ultrasonic surgical device including an elongate waveguide having a longitudinal axis and a distal end, and a blade extending away from the distal end of the waveguide, the blade including a curved portion that has at least five faces extending lengthwise along at least a portion of the length of the blade. Each of the faces has a width that extends perpendicular to the longitudinal axis of the waveguide and a length that extends orthogonal to the width. Each of the faces is flat across its width and is either flat along its entire length or includes one or more curved segments along its length, with each of the curved segments of an individual face being curved in the same direction. A method of fabricating an ultrasonic surgical device is also provided.

Curved ultrasonic surgical blade

An ultrasonic surgical device including an elongate waveguide having a longitudinal axis an a distal end, and a blade extending away from the distal end of the waveguide, the blade including a curved portion that includes first and second opposed faces extending lengthwise along at least a portion of the length of the blade. Each of the first and second faces has a width that extends perpendicular to the longitudinal axis of the waveguide and a length that extends orthogonal to the width. A pair of hook portions are located on opposite sides of the blade. A method of fabricating an ultrasonic surgical device is also provided.

A balanced ultrasonic surgical instrument according to the present invention includes an ultrasonic transmission rod which is connected to a blade or end effector by a balance portion, which includes first and second balance asymmetries designed to compensate for the imbalances induced by the blade.

Balanced ultrasonic end effector

An ultrasonic surgical blade includes an ultrasonic-surgical-blade body having a longitudinal axis, a distal tip, a proximal end adapted for longitudinal ultrasonic vibrational excitation, a most-distal longitudinal vibration node, a treatment portion extending from the distal tip toward the most-distal longitudinal vibration node, and a functional asymmetry. The functional asymmetry is asymmetric about the longitudinal axis and translates longitudinal ultrasonic vibrational movement of the proximal end into a combination of a longitudinal ultrasonic vibration and a transverse ultrasonic vibration in at least some of the treatment portion of the ultrasonic-surgical-blade body. An amplitude of the transverse ultrasonic vibration at the distal tip is less than substantially ten percent of a maximum amplitude of the transverse ultrasonic vibration of the treatment portion of the ultrasonic-surgical-blade body. An alternate embodiment of the ultrasonic surgical blade includes at least one functional asymmetry and at least one balance asymmetry.

Ultrasonic surgical blade having transverse and longitudinal vibration

A method and apparatus to facilitate nutritional malabsorption by diverting digestive secretions, such as bile or pancreatic secretions. A tube is positioned substantially within the small intestine. The tube comprises a proximal end which when deployed is operative to receive digestive secretions, a distal end which when deployed is operative to discharge the digestive secretions into the alimentary tract, and a tube wall having an inner surface and an outer surface, the tube wall inner surface defining passage extending between the proximal and distal ends. When deployed the passage is operative to transfer the digestive secretions from the proximal end to the distal end thereby reducing digestive contact between the digestive secretions and food in the small intestine.
