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 bipolar electrosurgical instrument has a first and a second set of needle like structures. Each set of needle like structures is functional for puncturing the skin of a patient on opposing sides of a wound or cut. Each needle comprises a body and a pointed portion at a distal end. The distal end is structured to form a sealing surface with an opposing needle on a needle of the other set. The sealing surfaces are adapted to connect to an electrical energy source such that the sealing surfaces are capable of conducting bipolar energy therebetween. The first and second set of needle like structures are movable from a first position where the needles are disposed in spaced relation relative to one another to a second position where the first and second sets of needles members are closer to one another. A mechanical force applied to or within a housing is utilized to move the needles sets from the first position to the second position.
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.

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.

An endoscopic forceps includes an elongate shaft defining an instrument axis. An end effector includes first and second jaw members each supporting an opposed sealing surface for clamping tissue. At least one of the jaw members is movable relative to the instrument axis such that the jaw members are movable between a first spaced-apart configuration and a second closed configuration for grasping tissue. A cutting instrument includes a reciprocating blade translatable relative to the sealing surfaces to sever tissue clamped between the jaw members. The reciprocating blade contacts an undersurface of at least one of the jaw members when the jaw members are in the second configuration to define a gap distance between the sealing surfaces. A handle adjacent the proximal end of the elongate shaft is operable to induce motion in the jaw members, and an actuator is operable to selectively translate the reciprocating blade.
