摘要： A surgical instrument includes an elongated shaft having a distal portion and a proximal portion coupled to a housing. An inner shaft member extends at least partially through the elongated shaft and is selectively movable in a longitudinal direction. An end effector is supported by the distal portion of the elongated shaft. The end effector includes upper and lower jaw members pivotally coupled to the distal portion of the elongated shaft about a pivot axis and including a pair of laterally spaced flanges. The pairs of flanges of the jaw members are arranged in an offset configuration such that one flange of the upper jaw member is positioned on a laterally exterior side of a corresponding flange of the lower jaw member, and the other flange of the upper jaw member is positioned on a laterally interior side of the other flange of the lower jaw member.

摘要： A method for manufacturing an end effector assembly is provided. The method includes grasping a gap-setting gauge between first and second jaw members moveable relative to one another about a pivot between a first, spaced-apart position and a second position proximate tissue and setting the first and second jaw members such that in the approximated position the jaw members cooperate to define a gap distance between the jaw members equivalent to the thickness of the gap-setting gauge such that when positioning tissue between the jaw members full approximation of the jaws is limited to the gap distance.

摘要： A surgical instrument includes a shaft formed via extrusion. The shaft has one or more lumens extending therethrough. The lumen(s) each define a cross-sectional configuration. An end effector assembly is coupled to a distal end of the shaft. One or more components are coupled to the end effector assembly. The component(s) extend proximally from the end effector into the lumen(s) of the shaft. One or more of the components is formed via stamping. The component(s) define a cross-sectional configuration substantially complementary to the cross-section configuration of the lumen into which they extend.

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.

摘要： A forceps includes an end effector assembly having first and second jaw members, each jaw member including a tissue sealing plate disposed thereon. 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 defines a first channel extending therethrough and an opening in the tissue sealing plate thereof that is aligned with the first channel. A stop member having a pre-determined configuration is removably engaged within the first channel. At least a portion of the stop member is configured to extend through the opening of the tissue sealing plate to define a minimum gap distance between the tissue sealing plates of the jaw members when the jaw members are disposed in the approximated position.

摘要： 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.

摘要： A method for manufacturing a pair of jaw members configured for use with an electrosurgical forceps is provided. One or more pairs of seal plates are stamped from a sheet metal. The seal plates are positioned into respective mold cavities. An insulative substrate is introduced into the respective mold cavities. The insulative substrate is allowed to harden in the respective mold cavities to form respective jaw housings with seal plates secured thereto. The jaw housings are removed from the respective mold cavities to form a pair of jaw members.

摘要： 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.

摘要： An electrosurgical forceps is provided with a shaft that extends from a housing of the electrosurgical forceps. An end effector assembly operably coupled to a distal end of the shaft includes a pair of first and second jaw members each having jaw housing and an electrosurgical seal plate. One or both of the first and second jaw members is movable from an open configuration, to a clamping configuration. The moveable jaw member includes an elongated channel defined in its respective jaw housing and extends along a length thereof. A drive assembly operably couples to the moveable jaw member via a drive rod that is engageable with the elongated channel to move the movable jaw member from the open configuration to the clamping configuration and to provide a closure force between the first and second jaw members when the jaw members are in the clamping configuration.
