    摘要: 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.

    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: An endoscopic forceps is provided. The endoscopic forceps includes a housing having a shaft that extends therefrom and defines a longitudinal axis therethrough. An end effector assembly operatively connects to a distal end of the shaft and has a movable jaw member and a non-movable jaw member. The movable jaw member has a substantially flexible medial portion and is movable relative to the non-movable jaw member from an initial position for positioning tissue therebetween, to a subsequent or clamping position wherein the movable and non-movable jaw members cooperate to grasp tissue therebetween. A drive assembly is operably coupled to the housing and includes a drive wire that operably couples to the movable jaw member. Proximal movement of the drive rod causes the medial portion of the movable jaw member to flex inwardly along a substantial length thereof and toward the non-movable jaw member.

    摘要: A surgical instrument includes a housing, an end effector and an elongated shaft extending therebetween. The end effector is movable between open and closed configurations. The elongated shaft includes a distal portion that is movable between aligned and articulated configurations. The surgical instrument further includes a driving assembly that induces motion in the end effector between open and closed configuration and maintains a closure pressure in the range of about 3 kg/cm2 to about 16 kg/cm2 between aligned and articulated configurations of the elongated shaft.

    摘要: 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.
