Electrosurgical instrument including a cutting member decouplable from a cutting member trigger
First Claim
1. An electrosurgical instrument, comprising:
- a first arm comprising a first finger ring and a first jaw;
a second arm pivotally connected to the first arm, the second arm comprising;
a second finger ring;
a second jaw;
a cutting member movable within the first and second jaws; and
a cutting member trigger;
a coupling system comprising a coupling member mechanically coupled to the cutting member trigger, wherein the coupling member is movable between a first position and a second position, wherein;
in the first position of the coupling member, the coupling member is mechanically uncoupled from the cutting member; and
in the second position of the coupling member, the coupling member is in contact with the cutting member; and
a movement arm mechanically coupled to the first and second arms, wherein the movement arm is configured to move the coupling member toward contact with the cutting member as the first and second jaws are moved toward a closed position.

Abstract
An electrosurgical instrument. The electrosurgical instrument includes a first arm, a second arm and a coupling system. The first arm includes a first jaw. The second arm is pivotably connected to the first arm and includes a second jaw, a cutting member movable within the first and second jaws, and a cutting member trigger. The coupling system includes a coupling member mechanically coupled to the cutting member trigger. The coupling member is movable between a first position and a second position. In the first position of the coupling member, the cutting member is mechanically uncoupled from the cutting member trigger. In the second position of the coupling member, the cutting member is mechanically coupled to the cutting member trigger.

12. An electrosurgical instrument, comprising:
-
a first arm comprising a first finger ring and a first jaw; a second arm pivotally connected to the first arm, the second arm comprising; a second finger ring; a second jaw comprising an electrode configured to apply electrosurgical energy to a tissue positioned between the first and second jaws; a cutting member movable within the first and second jaws, wherein the cutting member is configured to cut the tissue positioned between the first and second jaws; and a cutting member trigger; a coupling system comprising a coupling member mechanically coupled to the cutting member trigger, wherein the coupling member is movable between a first position and a second position, wherein; in the first position of the coupling member, the coupling member is mechanically uncoupled from the cutting member and movement of the cutting member trigger does not produce distal movement of the cutting member; and in the second position of the coupling member, the coupling member is in contact with the cutting member and movement of the cutting member trigger produces distal movement of the cutting member; and a movement arm mechanically coupled to the first and second arms, wherein the movement arm is configured to move the coupling member toward contact with the cutting member as the first and second jaws are moved toward a closed position. - View Dependent Claims (13, 14, 15)
