    摘要： 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. An actuator is included for selectively advancing 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. The actuator includes a trigger which cooperates with a rack and pinion system to advance the cutting mechanism from the first to second positions through tissue held therebetween.

    摘要： A bipolar electrosurgical instrument for clamping, grasping, manipulating, and sealing tissue includes first and second shafts each having a jaw member extending from a distal end thereof and a handle disposed at a proximal end thereof. The handle being operable to effect movement of the jaw members relative to one another from a first position wherein the jaw members are disposed in spaced relation relative to one another to a second position wherein the jaw members cooperate to grasp tissue therebetween. The bipolar instrument is connectable to a source of electrical energy having a first electrical potential connected to one of the jaw members and a second electrical potential connected to the other of the jaw members such that the jaw members are capable of selectively conducting energy though tissue held therebetween to effect a seal. Both the first and second electrical potentials are transmitted to the jaw members through the first shaft.

At least one of the jaw members includes a knife channel defined along a length thereof which is dimensioned to reciprocate a cutting blade therealong. An actuator is included which is operatively connected to one of the shaft members and selectively advances the cutting mechanism from a first position wherein the cutting blade is disposed proximal to tissue held between the jaw members to at least one subsequent position wherein the cutting blade is disposed distal to tissue held between the jaw members. The cutting blade is a generally hourglass-shaped flexible cutting blade having a notch disposed generally midway therealong which facilitates distal translation of the knife within the knife channel.

    摘要： A forceps includes an end effector assembly having first and second jaw members. One (or both) of the jaw members is moveable relative to the other between a spaced-apart position and an approximated position for grasping tissue therebetween. One (or both) of the jaw members includes an opposed jaw surface having an electrically-conductive tissue sealing plate disposed thereon. The electrically-conductive tissue sealing plate includes a first portion configured to conduct energy through tissue grasped between the jaw members to create a main tissue seal and a second portion including a plurality of spaced-apart fingers extending from the first portion. The second portion is configured to conduct energy through tissue grasped between the jaw members to create an auxiliary tissue seal extending from the main tissue seal for reducing stress concentrations adjacent the main tissue seal.
