Abstract: A surgical instrument includes an end effector assembly having jaw members movable to grasp tissue therebetween. One or both jaw members is adapted to connect to a source of energy for treating tissue grasped and one or both of the jaw members is adapted to connect to a source of energy for electrically cutting tissue. A first switch assembly is selectively activatable for supplying energy to treat tissue. A second switch is selectively activatable for supplying energy to electrically cut tissue. The tactile feel and range of motion during actuation of the second switch assembly mimics the tactile feel and range of motion of activation of a mechanical actuator that advances a cutting blade between the jaw members to mechanically cut tissue.

Abstract: An end effector assembly for an endoscopic surgical instrument includes a pair of jaw members disposed in opposing relation relative to one another. One or both of the jaw members is moveable relative to the other between a spaced-apart position and an approximated position for grasping tissue therebetween. Each jaw member defines an arcuate configuration and includes a proximal segment and a distal segment coupled to the proximal segment. The distal segment is moveable with respect to the proximal segment between a use position, wherein the proximal segment and the distal segment cooperate to define the arcuate configuration of the jaw member, and an insertion position, wherein the distal segment is offset relative to the proximal segment to interrupt the arcuate configuration of the jaw member.

An actuator selectively advances the cutting mechanism from a first position proximal to tissue held between the jaw members to a subsequent position distal to tissue held between the jaw members. The cutting mechanism includes a generally hourglass-shaped flexible blade having a mutually aggregating notch.

Abstract: 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.
