International Classification:

A61B 18/18

US Classification:

606 51, 606 52, 606205, 606 45

Abstract:

An electrosurgical instrument for performing at least one of sealing and dividing tissue includes a housing having a shaft attached thereto, the shaft defining a longitudinal axis. The electrosurgical instrument also includes a first jaw member movable relative to a second jaw member, the first jaw member attached to the shaft and being relatively movable from a first open position wherein the jaw members are disposed in spaced relation relative to one another to a second closed position wherein the jaw members cooperate to grasp tissue therebetween. The instrument also includes a drive rod assembly for imparting movement of the jaw members between the first and second positions and a rotating assembly attached to the housing for rotating the jaw members about the longitudinal axis. A knife assembly is also attached to the housing for separating tissue grasped between the jaw members and a handle assembly is attached to the housing for actuating the drive rod assembly. The instrument also includes first and second electrical leads which connect the jaw members to a source of electrical energy such that the jaw members are capable of conducting energy through tissue held therebetween.

International Classification:

A61B 18/04

US Classification:

606 48, 606 49, 606 51, 606 52

Abstract:

A removable electrode assembly for use in combination with a forcep having opposing end effectors and a handle for effecting movement of the end effectors relative to one another. The electrode assembly includes a housing which is removably engageable with the forceps and a pair of electrodes which are attachable to a distal end of the housing. The electrodes are removably engageable with the end effectors of the forceps such that the electrodes reside in opposing relation relative to one another. The electrode assembly also includes a cover plate which is removably attachable to the housing and at least one stop member () for controlling the distance between the opposing electrodes. The stop member is selectively engageable with the electrodes.

International Classification:

A61B 18/18

US Classification:

606 51, 606 45, 606205

Abstract:

An open electrosurgical forceps for sealing tissue includes a pair of first and second shaft members each having a jaw member disposed at a distal end thereof. The jaw members are movable from a first position in spaced relation relative to one another to a subsequent position wherein the jaw members cooperate to grasp tissue therebetween. Each of the jaw members includes an electrically conductive sealing plate for communicating electrosurgical energy through tissue held therebetween. At least one of the jaw members includes a cutting slot defined along a length thereof which is dimensioned to reciprocate a cutting instrument therealong for cutting tissue disposed between jaw members. An actuator advances the cutting instrument from a first position wherein the cutting instrument is disposed proximal to tissue held between the jaw members to at least one subsequent position wherein the cutting instrument is disposed distal to tissue held between the jaw members.

International Classification:

A61B 18/12

US Classification:

606 51, 606 49

Abstract:

An endoscopic bipolar forceps for sealing and dividing tissue which includes an elongated shaft having opposing jaw members at a distal end thereof. The jaw members are movable relative to one another about a pivot from a first spaced position to a second closed position to grasp tissue. Each jaw member is adapted to couple to a generator for conducting energy to effect a seal. The forceps also includes a handle assembly and a longitudinally reciprocating knife assembly which is translatable to sever tissue. The knife assembly includes a bifurcated knife bar having two forks which ride about the pivot during translation of the knife. One or more non-conductive stop members are operatively associated with the jaw members to regulate the distance between the jaw members when closed.

International Classification:

A61B 18/18

US Classification:

606 51, 606 50

Abstract:

An electrosurgical instrument which includes opposing end effectors and a handle for effecting movement of the end effectors relative to one another. The instrument includes a housing and a pair of electrodes. Each electode preferably includes an electrically conductive surface (e. g. , which can be dimensioned for sealing, clamping and/or cutting) and an insulating substrate which is dimensioned to be engageable with the end effectors such that the electrodes reside in opposing relation relative to one another. The dimensions of the insulating substrate are different from the dimensions of the electrically conductive surface to reduce thermal spread to adjacent tissue structures. The insulating substrate is made from a material having a Comparative Tracking Index of about 300 volts to about 600 volts to reduce the incidence of flashover.

An open electrosurgical forceps for sealing tissue includes a pair of first and second shaft members each having a jaw member disposed at a distal end thereof. The jaw members are movable from a first position in spaced relation relative to one another to a subsequent position wherein the jaw members cooperate to grasp tissue therebetween. Each of the jaw members includes an electrically conductive sealing plate for communicating electrosurgical energy through tissue held therebetween. At least one of the jaw members includes a knife channel defined along a length thereof which is dimensioned to reciprocate a cutting mechanism therealong for cutting tissue disposed between jaw members. An actuator having a rack and pinion system advances the cutting mechanism from a first position wherein the cutting mechanism is disposed proximal to tissue held between the jaw members to at least one subsequent position wherein the cutting mechanism is disposed distal to tissue held between the jaw members.
