A movable handle is included that actuates the shaft to move the jaw members relative to one another At least one of the jaw members is adapted to connect to a source of electrical energy such that one or both jaw members are capable of conducting energy to tissue held therebetween. An insulating boot is disposed on at least a portion of an exterior surface of one or both jaw members about the pivot and at a distal end of the shaft. The insulating boot includes an overmolded thermoplastic clevis disposed on an inner periphery thereof that is configured to enhance the mechanical engagement of the insulating boot with the one or both jaw members and the distal end of the shaft. | 04-02-2009 |
| 20090088749 | Insulating Boot for Electrosurgical Forceps with Exohinged Structure - 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 the shaft to move the jaw members relative to one another. One or both of the jaw members are adapted to connect to a source of electrical energy such that the jaw members are capable of conducting energy to tissue held therebetween. An insulating boot is disposed on at least a portion of an exterior surface of one or both jaw members, about the pivot and at a distal end of the shaft. The insulating boot includes an inner flexible portion and an outer shell that is operably engaged with one or both of the pair of jaw members. | 04-02-2009 |
| 20090088750 | Insulating Boot with Silicone Overmold for Electrosurgical Forceps - 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. | 04-02-2009 |
| 20110077648 | Switch Assembly for Electrosurgical Instrument - 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. | 03-31-2011 |
| 20110082457 | Apparatus, System, and Method for Performing an Electrosurgical Procedure - A bipolar forceps includes a shaft extending from a housing and includes an end effector assembly at its distal end. The end effector assembly has a pair of jaw members movable between an open position and a closed position. A knife assembly includes a cutter having a generally circular cross-section. The cutter is configured to cut tissue when the jaw members are in the closed position. One or more electrically conductive tissue sealing plates are disposed on each of the jaw members. The tissue sealing plates are adapted to connect to an electrosurgical energy source configured to deliver electrosurgical energy to tissue held between the jaw members to effect a tissue seal. An actuator is operably coupled to the knife assembly and is configured to selectively reciprocate the cutter relative to the jaw members. | 04-07-2011 |
| 20110082494 | Jaw, Blade and Gap Manufacturing for Surgical Instruments With Small Jaws - An endoscopic forceps includes an elongate shaft defining an instrument axis. An end effector includes first and second jaw members each supporting an opposed sealing surface for clamping tissue. At least one of the jaw members is movable relative to the instrument axis such that the jaw members are movable between a first spaced-apart configuration and a second closed configuration for grasping tissue. A cutting instrument includes a reciprocating blade translatable relative to the sealing surfaces to sever tissue clamped between the jaw members. The reciprocating blade contacts an undersurface of at least one of the jaw members when the jaw members are in the second configuration to define a gap distance between the sealing surfaces. A handle adjacent the proximal end of the elongate shaft is operable to induce motion in the jaw members, and an actuator is operable to selectively translate the reciprocating blade. | 04-07-2011 |
| 20110276048 | Surgical Forceps - A forceps includes a housing, a shaft, and an end effector assembly. The end effector assembly includes first and second jaw members. At least one of the jaw members is moveable with respect to the other between a spaced-apart position and an approximated position for grasping tissue therebetween. A cutting member having a plurality of cutting edges symmetrically-disposed about a longitudinal axis thereof is disposed within the shaft and is longitudinally translatable between a retracted position and an extended position. The cutting member extends between the jaw members to cut tissue grasped therebetween when in the extended position. The cutting member is fixedly-oriented with respect to the shaft and is configured for translation between the jaw members to cut tissue therebetween when the jaw members are rotated with respect to the shaft between about zero degrees and about 180 degrees in at least one of the clockwise and counterclockwise directions. | 11-10-2011 |
