Abstract

An electrosurgical forceps device, including a first arm having a first distal end. A second arm having a second distal end is included, the first arm and the second arm being pivotally coupled together. The first arm includes a first electrode at the first distal end and the second arm includes a second electrode at the second distal end. The first electrode and the second electrode are configured to deliver bipolar radiofrequency energy to the tissue. At least one moveable finger grip is disposed on at least one the first arm and the second arm. The device is transitionable between a first configuration, in which the first arm and the second arm are configured to grasp tissue between the first end and the second end, and a second configuration, in which at least one of the first arm and the second arm defines scissors configured to mechanically cut tissue.

First claim

What is claimed is:

1 . An electrosurgical forceps device, comprising:
a first arm having a first distal end; a second arm having a second distal end, the first arm and the second arm being pivotally coupled together; the first arm including a first electrode at the first distal end; the second arm including a second electrode at the second distal end, the first electrode and the second electrode being configured to deliver bipolar radiofrequency energy to the tissue; at least one moveable finger grip disposed on at least one the first arm and the second arm; and the device being transitionable between a first configuration, in which the first arm and the second arm are configured to grasp tissue between the first end and the second end, and a second configuration, in which at least one of the first arm and the second arm defines scissors configured to mechanically cut tissue.

2 . The device of claim 1 , wherein the first electrode and the second electrode are configured to at least one of resect and coagulate tissue.

3 . The device of claim 1 , wherein movement of the at least one moveable finger grip causes the transition of the device from the first configuration to the second configuration.

4 . The device of claim 3 , wherein the first arm includes a proximal portion, a distal portion and a hinge there between, and wherein the distal portion is pivotable with respect to the proximal portion.

5 . The device of claim 4 , wherein when the movable finger grip is in a first position the distal portion of the first arm is locked in a position away from the second arm, and wherein when the moveable finger grip is in a second position the distal portion of the first arm is in contact with the second arm.

6 . The device of claim 1 , wherein at least one of the first arm and the second arm defines a fluid pathway therein and a port configured to release a fluid from the fluid pathway.

7 . The device of claim 1 , wherein the entirety of the scissors is defined by the at least one of the first arm and the second arm.

8 . The device of claim 8 , wherein the scissors is disposed between the first arm and the second arm.

9 . The device of claim 1 , further including an engagement element disposed between the first arm and the second arm proximate the at least one moveable finger grip, the engagement element being configured to bias the first arm away from the second arm.

10 . The device of claim 9 , wherein the engagement element includes a biasing member between the first arm and the second arm.

11 . The device of claim 1 , wherein at least one of the first arm and the second arm defines a recess configured to receive a corresponding protrusion on the opposite one of the at least one of the first arm and the second arm.

12 . The device of claim 1 , further including an electrical connector coupled to the proximal ends of both of the first arm and the second arm, the electrical connector being configured to electrically couple with a radiofrequency generator.

13 . An electrosurgical forceps device, comprising:
a first arm having a first distal end; a second arm having a second distal end, the first arm and the second arm being pivotally coupled together; the first arm including a first electrode at the first distal end; the second arm including a second electrode at the second distal end, the first electrode and the second electrode being configured to deliver bipolar radiofrequency energy to the tissue; and a scissors assembly movably coupled to at least a portion of the first arm and at least a portion of the second arm.

14 . The device of claim 13 , wherein the scissors assembly is disposed between the first arm and the second arm.

14 . The device of claim 14 , wherein the scissors assembly includes a first carrier element slideably coupled to the first arm and a second carrier element slideably coupled to the second arm, and wherein the scissors assembly includes scissors coupled to the first carrier element and the second carrier element.

16 . The device of claim 15 , wherein the device is transitionable between a first configuration, in which the first arm and the second arm are configured to grasp tissue between the first end and the second end, and a second configuration, in which the scissors extends beyond the first end and the second end and is configured to mechanically cut tissue.

17 . The device of claim 16 , further defining a fluid flow pathway disposed within it least one of the first arm and the second arm, and wherein at least one of the first arm and the second arm define a port, the port being in fluid communication with the fluid flow pathway.

18 . The device of claim 17 , wherein the scissors are biased in an open configuration in which the first arm is a predetermined distance away from the second arm, and wherein movement of the first arm toward the second arm transitions the scissors from an open configuration to a closed configuration.

19 . An electrosurgical forceps device, comprising:
a first arm having a first distal end; a second arm having a second distal end, the first arm and the second arm being pivotally coupled together; the first arm including a first electrode at the first distal end; the second arm including a second electrode at the second distal end, the first electrode and the second electrode being configured to deliver bipolar radiofrequency energy to the tissue configured to at least one of resect and coagulate tissue; the device being transitionable between a first configuration, in which the first arm and the second arm are configured to grasp tissue between the first end and the second end, and a second configuration, in which at least one of the first arm and the second arm defines scissors configured to mechanically cut tissue; at least one of the first arm and the second arm defines a recess configured to receive a corresponding protrusion on the opposite one of the at least one of the first arm and the second arm; an electrical connector coupled to the proximal ends of both of the first arm and the second arm, the electrical connector being configured to electrically couple with a radio frequency generator; at least one moveable finger grip disposed on at least one the first arm and the second arm, wherein movement of the at least one moveable finger grip causes the transition of the device from the first configuration to the second configuration, and when the movable finger grip is in a first position the distal portion of the first arm is locked in a position away from the second arm, and wherein when the moveable finger grip is in a second position the distal portion of the first arm is in contact with the second arm. the first arm includes a proximal portion, a distal portion and a hinge there between, and wherein the distal portion is pivotable with respect to the proximal portion; and at least one of the first arm and the second arm defines a fluid pathway therein and a port configured to release a fluid from the fluid pathway.
