摘要： An electrosurgical forceps includes a shaft having a pair of jaw members at a distal end thereof that are movable about a pivot 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 are closer to one another for grasping tissue. A movable handle is included that actuates a drive assembly to move the jaw members relative to one another and one or more of the jaw members is adapted to connect to a source of electrical energy such that the jaw members are capable of conducting energy to tissue held therebetween. An insulative material, e.g., silicone, is overmolded atop at least a portion of an exterior surface of one or both jaw members, about the pivot and the distal end of the shaft.

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 method for cardiac surgical intervention relies on sealing or fusing heart valve leaflets without requiring implanted materials such as sutures or staples. The method provides a forceps having at least one shaft and an end effector assembly attached thereto. The end effector assembly includes a pair of opposing jaw members configured to move from an open, spread position to a closed, grasping position; creating at least one opening in the patient for inserting the forceps therein; inserting through the opening and manipulating jaw members of the forceps to grasp a portion of a first heart valve leaflet and a portion of a second heart valve leaflet therebetween; activating the forceps to close the jaw members about the leaflet portions under a working pressure, applying radiofrequency energy to the jaw members to seal the portion of the first heart valve leaflet to the portion of the second heart valve leaflet.

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 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.
