    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 the shaft includes a pair of first and second jaw members. One or both of the first and second jaw members is movable from an open configuration, to a clamping configuration. A knife blade assembly includes a knife blade translatable within the first and second jaw members. A knife blade lockout mechanism is in operative communication with the knife blade assembly and includes an elongated cam slot with a cam pin translatable therein from a distal end of the elongated cam slot corresponding to the knife blade lockout mechanism engaged with the knife blade assembly, to a proximal position corresponding to the knife blade lockout mechanism disengaged from the knife blade assembly.

    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.

    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 clip-over disposable assembly includes a switch assembly and a disposable body. The disposable body includes a first disposable member, a second disposable member including first and second wall portions, and a third disposable member. The first wall portion defines a first aperture therethrough and a first cavity configured to receive therein a first portion of the switch assembly. The third disposable member includes a third wall portion, wherein a body of the second disposable member and the third wall portion define an opening configured to allow a shaft of a hemostat-style surgical instrument to pass therethrough. The second wall portion and the third wall portion cooperatively define a chamber in communication with the opening and configured to receive therein at least a portion of the shaft of the hemostat-style surgical instrument, wherein the at least a portion of the shaft is received in the chamber from an off-axis position.
