Movable handle for vessel sealer
First Claim
1. A bipolar forceps, comprising:
- a shaft having opposing jaw members at a distal end thereof, the shaft defining a longitudinal axis;
a drive assembly for moving the jaw members 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; and
a handle assembly operatively connected to a proximal end of the shaft, the handle assembly including;
a first handle and a second handle, wherein the handle assembly is pivotable between a first position in which handle assembly is angled with respect to the longitudinal axis and a second position in which the handle assembly is substantially axially aligned with the longitudinal axis.

Abstract
Bipolar forceps are provided including a shaft having opposing jaw members at a distal end thereof, the shaft defining a longitudinal axis; a drive assembly for moving the jaw members 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; and a handle assembly operatively connected to a proximal end of the shaft. The handle assembly includes a first handle and a second handle, wherein the handle assembly is pivotable between a first position in which handle assembly is angled with respect to the longitudinal axis and a second position in which the handle assembly is substantially axially aligned with the longitudinal axis.

12. 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;
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 drive rod assembly for imparting movement of the jaw members between the first and second positions;
a rotating assembly attached to the housing for rotating the jaw members about the longitudinal axis;
a knife assembly attached to the housing for separating tissue grasped between the jaw members;
a handle assembly pivotally attached to the housing for actuating the drive rod assembly, the handle assembly including;
a first handle and a second handle, wherein the handle assembly is pivotable between a first position in which handle assembly is angled with respect to the longitudinal axis and a second position in which the handle assembly is substantially axially aligned with 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
a handswitch attached to the housing which allows a user to selectively energize the jaw members. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
