Vessel sealer and divider
First Claim
1. An endoscopic bipolar forceps, comprising:
- a housing;
an elongated shaft extending distally from the housing and having first and second jaw members towards a distal end thereof, the first and second jaw members movable relative to one another from a first position in spaced relation relative to one another to a second position where the jaw members cooperate to grasp tissue therebetween;
a rotation knob disposed on the housing and disposed about the elongated shaft towards a proximal end of the elongated shaft such that the elongated shaft rotates in response to rotation of the rotation knob;
each jaw member adapted to connect to an energy source such that upon activation thereof the first and second jaw members selectively conduct energy through tissue held therebetween to effect a tissue seal;
a first cable lead cooperating with a plurality of first cable guides to route the first cable lead through the rotation knob and the elongated shaft, the first cable lead including a slack, looped portion disposed within the rotation knob; and
a second cable lead cooperating with a plurality of second cable guides to route the second cable lead through the rotation knob and the elongated shaft, the second cable lead including a slack, looped portion disposed within the rotation knob,wherein the first cable lead transmits a first electrical potential from the energy source to the first jaw member and the second cable lead transmits a second electrical potential from the energy source to the second jaw member, such that the first and second jaw members are electrically isolated from each other.

Abstract
An endoscopic bipolar forceps includes an elongated shaft having opposing jaw members at a distal end thereof. The jaw members 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. The forceps also includes a source of electrical energy connected to each jaw member such that the jaw members are capable of conducting energy through tissue held therebetween to effect a seal. A generally tube-like cutter is included which is slidably engaged about the elongated shaft and which is selectively movable about the elongated shaft to engage and cut tissue on at least one side of the jaw members while the tissue is engaged between jaw members.
