Abstract: An endoscopic bipolar forceps includes a housing and a shaft affixed to the housing. The shaft includes a longitudinal axis defined therethrough and a pair of jaw members attached to a distal end thereof. The forceps also includes a drive assembly for moving one of the jaw members relative to the other jaw member. A movable handle is included which moves the jaw members from the open and closed positions. The forceps is adapted to connect to a source of electrosurgical energy such that the jaw members are capable of conducting bipolar energy through tissue held therebetween to effect a tissue seal. A trigger assembly is operatively disposed relative to the movable handle for selectively advancing a knife assembly for cutting tissue along the tissue seal.

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.

Abstract: An endoscopic bipolar forceps includes a housing and a shaft affixed to the housing. The shaft includes a longitudinal axis defined therethrough and a pair of jaw members attached to a distal end thereof. The forceps also includes a drive assembly for moving one of the jaw members relative to the other jaw member from a first position wherein the movable jaw members are disposed in spaced relation relative to each other to a second position wherein the jaw members are closer one another for manipulating tissue. A movable handle is included which is rotatable about a pivot to force a drive flange of the movable handle into mechanical cooperation with the drive assembly to move the jaw members from the open and closed positions. The pivot is located a fixed distance from the longitudinal axis and the drive flange is located generally along the longitudinal axis.

Abstract: A disposable open electrosurgical forceps for sealing tissue is disclosed in the present disclosure. The disposable open electrosurgical forceps comprise a pair of first and second shaft members containing a fiber reinforced thermoplastic blend material having fiber strands of at least 2 millimeters in length. Each shaft member includes a jaw member disposed at a distal end thereof which are movable from a first position in spaced relation relative to one another to at least one subsequent position wherein the jaw members cooperate to grasp tissue therebetween. Each of the jaw members also 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.

Abstract: An endoscopic bipolar forceps includes a housing and a shaft, the shaft having an end effector assembly at its distal end, which includes two jaw members for grasping tissue therebetween. Each jaw member is adapted to connect to an electrosurgical energy source, enabling them to affect a tissue seal to tissue held therebetween. A drive assembly is included within the housing for moving the jaw members and it includes first and second gear-like cam members. A movable handle is also included, such that movement of the handle rotates the first gear-like cam member into cooperation with the second gear-like cam member to actuate the drive assembly to move the jaw members relative to each other.

Abstract: A bipolar electrosurgical instrument has a pair of pivotable juxtaposed jaw members and a locking mechanism operatively associated with a second of the jaw members. The locking mechanism has a first position engaged with the second jaw member for preventing movement of the second jaw member between an axially aligned orientation and at least one angled orientation, and a second position. The second position is disengaged from the second jaw member allowing for movement of the second jaw member between the axially aligned orientation and the at least one angled orientation. The instrument has an actuation mechanism operatively connected to a first of the jaw members with the actuation mechanism operable to move the first jaw member between an axially aligned first orientation and at least one angled orientation. An articulation knob is operatively associated with the locking mechanism and effectuates independent operation of the locking and actuation mechanisms.
