Abstract: An electrosurgical forceps is provided with a shaft that extends from a housing of the electrosurgical forceps. An end effector assembly includes a pair of first and second jaw members pivotably coupled to one another via a pivot pin. One or both of the first and second jaw members may be movable from an open position for positioning tissue therebetween to a clamping position for grasping tissue. A detent is operably disposed proximal the pivot pin and extends radially outward from a proximal flange of one of the jaw members. The detent is configured to releasably engage a corresponding slot disposed on a proximal flange of the other jaw member. The detent and slot are configured to control a gap distance between the first and second jaw members when the first and second jaw members are in the clamping position.

Abstract: A method of manufacturing a forceps includes providing first and second jaw members and depositing an electrically-conductive tissue sealing plate atop each jaw member via vapor deposition. The jaw members are then coupled to one another to permit movement of one (or both) of the jaw members relative to the other between a spaced-apart position and an approximated position for grasping tissue between the tissue sealing plates thereof.

Abstract: A surgical forceps includes a first shaft member including a proximal portion having a handle at a proximal end thereof and a distal portion having a jaw member at a distal end thereof. The proximal and distal portions are pivotable between an aligned position and an angled position. A second shaft member includes a jaw member at a distal end thereof and a handle at a proximal end thereof. The shaft members are pivotable relative to one another between a spaced-apart position and an approximated position for moving the jaw members relative to one another between an open position and a closed position to grasp tissue therebetween. The proximal portion of the first shaft member is pivoted relative to the distal portion of the first shaft member from the aligned position to the angled position upon movement of the first and second shaft members towards the spaced-apart position.

Abstract: A forceps is provided and includes a housing having a shaft. An end effector assembly operatively connects to a distal end of the shaft and includes a pair of first and second jaw members. One or both of the first and second jaw members is movable relative to the other jaw member from a clamping position to an open position. A resilient member operably couples to at least one of the first and second jaw members. The resilient member is configured to bias the first and second jaw members in the clamping position and provide a closure force on tissue disposed therebetween.

Abstract: A surgical instrument includes an end effector assembly having first and second jaw members moveable relative to one another between a spaced-apart position and an approximated position for grasping tissue therebetween. In the approximated position, the jaw members cooperate to define a cavity that is configured to house tissue grasped between the jaw members. An injectable material configured for injection into the cavity defined by the jaw members is also provided. The injectable material is configured to substantially surround tissue housed within the cavity. The injectable material is transitionable from a first state, facilitating injection of the injectable material into the cavity, to a second state, wherein the injectable material forms about tissue housed within the cavity to occlude tissue.

Abstract: A surgical instrument includes an end effector assembly, first and second handles, and a drive assembly. The handles are pivotable relative to one another between a spaced-apart position and an approximated position. The drive assembly includes a drive bar and a biasing member. The drive bar is coupled to the end effector assembly such that translation of the drive bar effects movement of the end effector assembly between first and second positions. First and second ends of the biasing member are coupled to the respective first and second handles. An intermediate portion of the biasing member is coupled to the drive bar such that movement of the handles from the spaced-apart to the approximated position displaces the intermediate portion and urges the drive bar to translate relative to the end effector assembly to effect movement of the end effector assembly between the first and second positions.

Abstract: A bipolar forceps includes a mechanical forceps including first and second shafts each having a jaw member extending from a distal end thereof and a handle disposed at a proximal end thereof for effecting movement of the jaw members relative to one another about a pivot. A disposable housing is configured to releasably couple to at least one of the shafts and an electrode assembly is associated with the disposable housing. The electrode assembly includes electrodes releasably coupleable to the jaw members. At least one of the electrodes includes a knife channel configured to receive a knife blade therethrough to cut tissue grasped between the jaw members. A switch is configured to initiate delivery of electrosurgical energy from the source of electrosurgical energy to the electrodes. An actuation mechanism is configured to selectively advance the knife blade through the knife channel to cut tissue.

The first and second jaw members are set such that the jaw members are prevented from approximation beyond the gap-distance.

Abstract: A forceps includes an end effector assembly having first and second jaw members. Each of the jaw members includes a proximal flange extending therefrom. Each of the proximal flanges defines a bifurcated configuration having first and second spaced-apart flange components. The first flange component of the first jaw member is configured to pivotably engage the second flange component of the second jaw member via a first protrusion-aperture coupling. The first flange component of the second jaw member is configured to pivotably engage the second flange component of the first jaw member via a second protrusion-aperture coupling different from the first protrusion-aperture coupling. One or both of the jaw members is pivotable relative to the other about the first and second protrusion-aperture couplings between a spaced-apart position and an approximated position for grasping tissue therebetween.

Abstract: A surgical instrument includes a housing having a shaft extending therefrom. The housing includes a nose having a neck and a base that defines a diameter greater than that of the neck. A rotation knob has a distal end defining a first aperture and a proximal end defining a second aperture, the apertures cooperating to define a lumen extending through the rotation knob that is configured to receive the shaft. The first aperture defines a diameter that generally approximates a diameter of the shaft. The rotation knob is transitionable between an at-rest position and a flexed position. In the flexed position, the second aperture is expanded to permit passage of the base of the nose into an interior of the rotation knob. In the at-rest position, the second aperture generally approximates the diameter of the neck to rotatably engage the rotation knob about the nose with the shaft extending therethrough.
