    Abstract: 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.

    Abstract: An endoscopic forceps is provided and includes a housing having a shaft. An end effector assembly operatively connects to a distal end of the shaft and has a pair of first and second jaw members. One of the first and second jaw members is movable relative to the other jaw member from an open position, to a clamping position. One of the first and second jaw members includes one or more cam slots defined therein and configured to receive a cam member that upon movement thereof rotates the movable jaw member from the open position to the clamping position. A resilient member is operably coupled to the jaw member that includes the one or more cam slots. The resilient member is configured to provide a camming force to the cam slot and to bias the first and second jaw members in the clamping position.

    Abstract: A forceps includes a housing having a shaft. An end effector assembly operatively connects to a distal end of the shaft and includes a pair of first and second jaw members. One or both of the first and second jaw members is movable relative to the other jaw member from a clamping position to an open position. A resilient member operably couples to the first and second jaw members. The resilient member is configured to bias the first and second jaw members in the clamping position and provide a closure force on tissue disposed therebetween.

    Abstract: A surgical instrument includes an end effector and a housing mechanically coupled to the end effector. The end effector includes a first actuating device configured to perform a first surgical procedure and a second actuating device integrally associated with the first actuating device and configured to perform a second surgical procedure, the second surgical procedure being independently operable and different than the first surgical procedure. An outer portion of the first actuating device and an outer portion of the second actuating device form a portion of an outer housing of the end effector. The housing includes a first actuator, mechanically coupled to the first actuating device and configured to impart movement to the first actuating device and a second actuator, mechanically coupled to the second actuating device and configured to impart movement to the second actuating device.

    Abstract: An endoscopic forceps is provided and includes a housing having a shaft that extends therefrom. An end effector assembly is operatively connected to a distal end of the shaft and includes a pair of pivotably coupled first and second jaw members. The jaw members are movable relative to one another. A drive mechanism includes a driving structure. A link assembly includes two or more links that are operably coupled to each other and the drive structure. The two or more links are operably coupled to respective ones of the first and second jaw members.

    Abstract: A surgical instrument includes a housing, an inner shaft coupled to and extending distally from the housing, an end effector assembly disposed at a distal end of the inner shaft, an outer sheath that is fixed to the housing, extends distally from the housing, and is disposed about the inner shaft, and an insulative sleeve. The insulative sleeve is positioned between the inner shaft and the outer sheath. The insulative sleeve is movable relative to the inner shaft and the outer sheath between a storage position, wherein the insulative sleeve is positioned proximally of the end effector assembly, and a deployed position, wherein the insulative sleeve substantially surrounds the end effector assembly.
