摘要： The present disclosure is directed to an electrosurgical system. The electrosurgical system includes an electrosurgical generator configured to output electrosurgical energy and including a receptacle having at least one mechanical interface. The system also includes an electrosurgical instrument adapted to connect to the electrosurgical generator and configured to deliver energy to tissue. Further, a plug is provided to engage the receptacle to electrically couple the electrosurgical instrument to the electrosurgical generator. The plug includes a terminal electrically coupled to the electrosurgical instrument and a prong electrically coupled to the terminal that includes a recess defined therein and is configured to receive the at least one mechanical interface. When the plug is disengaged from the receptacle, the at least one mechanical interface cooperates with the recess to uncouple the prong from the terminal.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： A forceps includes an end effector assembly having first and second jaw members moveable with respect to one another between an open position and a closed position. A knife channel having a body and a base is defined within each jaw member. A knife assembly includes a knife having a bifurcated distal end.

The knife is translatable into the channels when the jaw members are in the closed position such that the cutting members are approximated when translated through the channels. The knife is also translatable into the channels when the jaw members are in the open position such that the cutting members are flexed apart when translated through the jaw members.

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.

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.
