Vessel sealer and divider
First Claim
1. An electrosurgical instrument, comprising:
- a housing having a shaft attached thereto, the shaft defining a longitudinal axis;
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;
a handle attached to the housing which imparts movement of the first jaw member from the first and second positions;
a rotating assembly attached to the housing which rotates the jaw members about the longitudinal axis;
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; and
at least one of the first and second electrical leads including a slack loop disposed in the rotating assembly which permits rotation of the jaw members about the longitudinal axis.

Abstract
An electrosurgical instrument includes a housing having a shaft attached thereto which connects a pair of first and second jaw members in an opposing manner relative to one another. The jaw members are movable relative to one another 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 handle which imparts movement of the first and second jaw members from the first and second positions and a rotating assembly for rotating the jaw members about a longitudinal axis defined through the shaft. A pair of electrical leads connect the jaw members to a source of electrical energy such that the jaw members are capable of conducting energy through tissue held therebetween. The leads include a slack-like loop disposed in the rotating assembly which permits rotation of the jaw members about the longitudinal axis without unduly straining the electrical leads.

10. An electrosurgical instrument for performing at least one of sealing and dividing tissue, comprising:
-
a housing having a shaft attached thereto, the shaft defining a longitudinal axis; first and second jaw members pivotally attached to the shaft in opposing relation relative to one another, the jaw members 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; a drive rod assembly operatively associated with the housing which imparts movement of the jaw members between the first and second positions; a handle attached to the housing which actuates the drive rod assembly; a rotating assembly attached to the housing which rotates the jaw members about the longitudinal axis; a knife assembly attached to the housing for separating tissue; 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; and at least one of the first and second electrical leads including a slack loop disposed in the rotating assembly which permits rotation of the jaw members about the longitudinal axis.
