Abstract: A surgical instrument includes a first actuation assembly coupled to a first component and movable from a first position to a second position to actuate the first component. A biasing member coupled to the first actuation assembly is configured to bias the first actuation assembly towards the first position. A second actuation assembly is coupled to a second component and is selectively actuatable to actuate the second component. The second actuation assembly is coupled to the first actuation assembly such that actuation of the second actuation assembly effects movement of the first actuating assembly from the first position towards the second position. A linkage assembly is configured to reduce the bias applied to the first actuation assembly when the second actuation assembly effects movement of the first actuation assembly.

Abstract: A surgical forceps including an end effector assembly has first and second jaw members. At least one of the first or second jaw members has a jaw frame defining a channel therein, an insulative member disposed within the channel of the jaw frame, and an electrically-conductive plate having a tissue contacting surface and at least one folded side portion. The insulative member includes a top portion having a tissue facing surface. The tissue contacting surface of the electrically-conductive plate is disposed on the tissue facing surface of the insulative member. The at least one folded side portion of the electrically-conductive plate is folded over the top portion of the insulative member such that the electrically-conductive plate conforms to a shape of the top portion of the insulative member.

Abstract: A surgical instrument including housing having a shaft extending distally therefrom, an outer sleeve disposed about the shaft and selectively translatable relative to the shaft, a first drive shaft disposed within the shaft and translatable relative to the shaft independently of the outer sleeve, a second drive shaft disposed within the first drive shaft and coupled to the outer sleeve to translate in conjunction with the outer sleeve, and a rotatable nose wheel. The rotatable nose wheel is mounted about a distal end of the housing and is rotatably coupled to each of the outer sleeve, the shaft, the first drive shaft, and the second drive shaft such that rotation of the rotatable nose wheel effects corresponding rotation of the outer sleeve, the shaft, the first drive shaft, and the second drive shaft in conjunction with one another and relative to the housing.

Abstract: An electrosurgical device is provided that includes a handset having a shaft extending therefrom, a pair of active electrodes at a distal end of the shaft, and a movable, electrically floating electrode selectively positionable between the active electrodes. The floating electrode, when positioned to contact tissue between the active electrodes, modifies the electrosurgical current flows through tissue. The resultant modified current flows enables a surgeon to more effectively to control tissue desiccation by focusing electrosurgical energy toward targeted tissue and by reducing peripheral current flows. Embodiments are provided wherein the active electrodes include cooling provisions. Related electrosurgical systems and method of use are also provided.

Abstract: A forceps includes an end effector assembly including first and second jaw members. One or both of the jaw members is movable relative to the other between a spaced-apart position and an approximated position for grasping tissue therebetween. One or both of the jaw members is configured to conduct energy between the jaw members and through tissue grasped therebetween to treat tissue. An insulative tubular member is movable relative to the end effector assembly between a retracted position, wherein the insulative tubular member is positioned proximally of the end effector assembly, and an extended position, wherein the insulative tubular member is disposed about the end effector assembly. A monopolar member is configured to apply energy to tissue to treat tissue when the insulative tubular member is disposed in the extended position.

Abstract: A desiccation device for operation on a target tissue includes a handle, a shaft extending distally from the handle, and a head. The shaft defines a lumen therethrough, and the head has a loop configuration supported on a distal end of the shaft. The head is hollow and defines a lumen therethrough. The lumen is in fluid communication with the lumen of the shaft. At least a portion of the head is electrically connected to a source of electrosurgical energy. A fluid is circulatable through the lumen of the shaft and the head.

Abstract: A method for dissecting a myoma from a uterine wall includes inserting a myomectomy screw retractor into a surgical site, articulating a tool assembly positioned at a distal end of the myomectomy screw retractor such that a screw of the tool assembly is positioned adjacent to the myoma orthogonal to the uterine wall, rotating the screw of the tool assembly into the myoma until the screw is substantially engaged with the myoma, manipulating the myoma by pitching, rotating, and/or providing traction to the myoma to expose cutting planes, and dissecting the myoma from the uterine wall by cutting along the exposed cutting planes.

Abstract: A surgical instrument comprises an end effector including a pair of jaw members configured to move with respect to one another between an open configuration and a closed configuration for clamping tissue. At least one jaw member includes an elongate cam slot extending in a longitudinal direction over a substantial a length a tissue clamping surface of the at least one jaw member. A plurality of electrically isolated, and longitudinally spaced electrodes is supported by the tissue clamping surface and is configured to deliver electrosurgical energy to tissue. A reciprocating member engages the elongate cam slot and is extendable to a sealing position with respect to each of the electrodes to define a predetermined gap distance between a particular electrode and an opposing tissue clamping surface.
