摘要： A forceps includes an end effector assembly having first and second jaw members. One (or both) of the first and second 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 a jaw frame a disposable jaw housing and an elastomeric ring member. The disposable jaw housing is releasably engageable with the jaw frame. The elastomeric ring member is removably positionable about a distal end of the jaw housing. The elastomeric ring member is configured to define a gap distance between the first and second jaw members upon movement of the first and second jaw members to the approximated position.

摘要： A forceps includes first and second shaft members each having a jaw member disposed at a distal end thereof. One (or both) of the first and second jaw members is moveable relative to the other between a spaced-apart position and an approximated position for grasping tissue therebetween. The first jaw member includes a jaw frame fixedly engaged to the first shaft member and a disposable jaw housing releasably engageable with the jaw frame. The disposable jaw housing includes a knife assembly disposed therein. The knife assembly includes a knife blade biased toward an initial position, wherein the knife blade is disposed within the jaw housing. The knife blade is moveable between the initial position and an extended position, wherein the knife blade extends at least partially from the jaw housing to cut tissue grasped between the first and second jaw members.

摘要： A forceps includes a pair of shafts each having a jaw member disposed at a distal end thereof. One (or both) of the shafts is moveable relative to the other about a pivot pin between a spaced-apart position and an approximated position to move the jaw members between an open position and a closed position. A knife assembly includes a knife blade mechanically keyed to the pivot pin and moveable between an initial position, wherein the knife blade is disposed within one of the jaw members, and an extended position, wherein the knife blade extends between the jaw members. An actuator arm(s) is mechanically keyed to the pivot pin and extends therefrom. The actuator arm(s) is moveable between an un-actuated position and an actuated position to rotate the pivot pin relative to the jaw members to move the knife blade between the initial position and the extended position.

摘要： An electrosurgical forceps includes a housing having a shaft affixed thereto, the shaft including jaw members at a distal end thereof. The forceps also includes a switch assembly that includes a supporting member, a flexible membrane circuit having snap dome switch contacts operably fixed thereto, and ergonomically-contoured keytops. The switch assembly provides at least one monopolar activation switch, and a bipolar activation switch. The forceps also include a drive mechanism which causes the jaw members to move relative to one another for manipulating tissue. A monopolar safety switch is incorporated into the switch assembly which cooperates with the drive mechanism to inhibit the monopolar activation switch when the jaw members are in an open position.

摘要： A surgical instrument includes an elongated shaft having a distal portion and a proximal portion coupled to a housing. An inner shaft member extends at least partially through the elongated shaft and is selectively movable in a longitudinal direction. An end effector is supported by the distal portion of the elongated shaft. The end effector includes upper and lower jaw members pivotally coupled to the distal portion of the elongated shaft about a pivot axis and including a pair of laterally spaced flanges. The pairs of flanges of the jaw members are arranged in an offset configuration such that one flange of the upper jaw member is positioned on a laterally exterior side of a corresponding flange of the lower jaw member, and the other flange of the upper jaw member is positioned on a laterally interior side of the other flange of the lower jaw member.
