摘要： 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.

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.

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.
