Abstract
An endoscopic bipolar forceps for sealing and dividing tissue includes an elongated shaft having opposing jaw members at a distal end thereof which are movable relative to one another from a first position wherein the jaw members are disposed in spaced relation relative to one another to a second position wherein the jaw members cooperate to grasp tissue therebetween. Each jaw member including an electrically conductive sealing surface having a non-stick coating disposed thereon which is designed to reduce tissue adherence. A source of electrical energy is connected to each jaw member such that the jaw members are capable of conducting energy through tissue held therebetween to effect a seal. A longitudinally reciprocating knife is included which severs tissue proximate the seal. The vessel sealer and divider also includes a non-conductive stop member disposed on the electrically conductive surface of one of the jaw members which controls the distance between the jaw members when tissue is held therebetween. A handle assembly is also included which is designed to maintain a closure pressure in the range of about 3 kg/cm2 to about 16 kg/cm2 between the electrically conductive sealin…
