    Abstract: An electrosurgical instrument including an end effector assembly having first and second jaw members and at least first and second thermal cutting elements. Each of the first and second jaw members includes an electrically conductive tissue contacting surface. At least one of the first or second jaw members is movable relative to the other from a spaced apart position to an approximated position to grasp tissue between the tissue contacting surfaces. The first and second jaw members are adapted to connect to a source of energy for electrosurgically treating tissue grasped between the tissue contacting surfaces. Each of the first and second thermal cutting elements is disposed on or within one of the first or second jaw members and adapted to connect to a source of energy for thermally treating tissue.

    Abstract: A removable component configured for insertion into an internal compartment of a surgical instrument is provided including a housing defining first and second ends, a grasping member, and a biasing member. The grasping member is operably coupled to the housing at the second end thereof and is movable relative to the housing between a presented position, wherein at least a portion of the grasping member is spaced-apart from the second end of the housing, and a stored position, wherein the grasping member is approximated relative to the second end of the housing. The biasing member is disposed between the grasping member and the second end of the housing and is configured to bias the grasping member towards the presented position. Systems including a surgical instrument and such a removable component and methods of assembling a surgical instrument using the same are also provided.

    Abstract: A jaw member for use with a surgical instrument includes a support base, a jaw liner, and a jaw overmold. The support base has a proximal portion configured to be pivotably coupled to a surgical instrument, and a distal portion. The support base defines a channel that extends longitudinally between the proximal and distal portions and an aperture disposed in communication with the channel. The jaw liner includes an elongate body configured for receipt in the channel of the support base, and a projection extending from the elongate body and configured for receipt in the aperture of the support base. The jaw overmold overlaps at least a portion of the support base and the jaw liner to fix the jaw liner to the support base.

    Abstract: An end effector assembly for an electrosurgical instrument includes a pair of opposing jaw members each having a jaw housing supporting an electrically conductive tissue engaging surface thereon. The tissue engaging surfaces are disposed in opposition relative to one another and one or both of the jaw members are movable relative to one another to grasp tissue therebetween. First, second and third thermal cutting elements are disposed on one or both of the tissue engaging surfaces. Each thermal cutting element is independently activatable (or activatable in pairs) relative to the tissue engaging surfaces and each thermal cutting element connects to an electrosurgical energy source. The first thermal cutting element is exposed along the length of the tissue engaging surface, the second thermal cutting element surrounds the distal tip of the jaw member and the third thermal cutting element is disposed on the back of the jaw housing.

    Abstract: A surgical instrument includes a housing, an end effector including a clamp jaw, a drive member extending distally from the housing, and a clamp lever pivotably coupled to the housing. The drive member is operably coupled to the clamp jaw such that translation of the drive member pivots the clamp jaw from an open position towards a clamping position. The clamp lever is operably coupled to the drive member via a rigid slider. The clamp jaw is configured to provide a jaw force to clamped tissue, measured at about 0.192 inches from a distal end of the clamp jaw, of from about 1 lbf to about 8 lbf in response to a full actuation of the clamp lever.
