摘要： An electrosurgical instrument for performing at least one of sealing and dividing tissue includes a housing having a shaft attached thereto, the shaft defining a longitudinal axis. The electrosurgical instrument also includes a first jaw member movable relative to a second jaw member, the first jaw member attached to the shaft and being relatively movable from a first open position wherein the jaw members are disposed in spaced relation relative to one another to a second closed position wherein the jaw members cooperate to grasp tissue therebetween. The instrument also includes a drive rod assembly for imparting movement of the jaw members between the first and second positions and a rotating assembly attached to the housing for rotating the jaw members about the longitudinal axis. A knife assembly is also attached to the housing for separating tissue grasped between the jaw members and a handle assembly is attached to the housing for actuating the drive rod assembly. The instrument also includes first and second electrical leads which connect the jaw members to a source of electrical energy such that the jaw members are capable of conducting energy through tissue held therebetween. A handswitch is attached to the housing to allow a user to selectively energize the jaw members.

摘要： 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 sealing surfaces during sealing.

摘要： An electrosurgical instrument which includes opposing end effectors and a handle for effecting movement of the end effectors relative to one another. The instrument includes a housing and a pair of electrodes. Each electode preferably includes an electrically conductive surface (e.g., which can be dimensioned for sealing, clamping and/or cutting) and an insulating substrate which is dimensioned to be engageable with the end effectors such that the electrodes reside in opposing relation relative to one another. The dimensions of the insulating substrate are different from the dimensions of the electrically conductive surface to reduce thermal spread to adjacent tissue structures. The insulating substrate is made from a material having a Comparative Tracking Index of about 300 volts to about 600 volts to reduce the incidence of flashover.

摘要： An endoscopic bipolar forceps for sealing and dividing tissue which includes an elongated shaft having opposing jaw members at a distal end thereof. The jaw members are movable relative to one another about a pivot from a first spaced position to a second closed position to grasp tissue. Each jaw member is adapted to couple to a generator for conducting energy to effect a seal. The forceps also includes a handle assembly and a longitudinally reciprocating knife assembly which is translatable to sever tissue. The knife assembly includes a bifurcated knife bar having two forks which ride about the pivot during translation of the knife. One or more non-conductive stop members are operatively associated with the jaw members to regulate the distance between the jaw members when closed.
