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 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 forceps includes an end effector assembly having first and second jaw members movable between a spaced-apart position and an approximated position for grasping tissue therebetween. A knife assembly having a cutting blade disposed at a distal end thereof is also provided. The knife assembly is translatable relative to the end effector assembly between a retracted position and an extended position, wherein the cutting blade extends between the jaw members to cut tissue grasped therebetween. The knife assembly includes a proximal component and a first distal component that includes the cutting blade. The proximal and first distal components are removably coupled to one another to facilitate replacement of the first distal component while the end effector assembly remains in a substantially assembled condition, i.e., without requiring substantial disassembly of the end effector assembly.

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. The end effector assembly includes first and second jaw members. At least one of the jaws is moveable with respect to the other between a spaced-apart position and at least one approximated position for grasping tissue therebetween. At least one of the jaw members is adapted to connect to a source of energy for sealing tissue disposed between the jaw members. A chamber is defined within and extends longitudinally along at least one of the jaw members. The chamber is configured to retain a fluid therein and includes a series of apertures disposed on a tissue-facing surface thereof such that, upon application of energy to the jaw member(s), fluid within the chamber is heated to thermally expand within the chamber and forcefully exit the apertures to divide tissue disposed between the jaw members.

摘要： A forceps includes an end effector assembly including a pair of jaw members disposed in opposing relation relative to one another. At least one jaw member is moveable relative to the other between a spaced apart position, a first approximated position, and a second approximated position. The jaw members are configured to apply a pre-determined pressure to tissue disposed therebetween in each of the first and second approximated positions. A sealing pressure is applied to tissue disposed between the jaw members when the jaw members are in the first approximated position. A cutting pressure is applied to tissue disposed between the jaw members when the jaw members are in the second approximated position.
