Abstract

A surgical device is disclosed that comprises a shaft member and a pair of electrodes. The shaft member has a pair of electrode channels that open at the distal end of the shaft member, wherein the electrode channels are positioned adjacent to one another. The pair of electrodes are configured to deliver energy, and one of the pair of electrodes is configured to be disposed in each electrode channel such that distal ends of each of the electrodes are arranged to protrude from the distal end of the shaft member. The shaft member further includes at least one lumen opening at the distal end of the shaft member. A lighting arrangement including a fiber optic cable configured to deliver light at the distal end of the fiber optic cable, the fiber optic cable positioned within the at least one lumen.

First claim

What is claimed is:

1 . A surgical device, comprising:
a shaft member including a pair of electrode channels that open at a distal end of the shaft member, wherein the electrode channels are positioned adjacent to one another; a pair of electrodes configured to deliver energy, wherein one of the pair of electrodes is disposed in each electrode channel such that distal ends of each of the electrodes are arranged to protrude from the distal end of the shaft member; wherein the shaft member further includes at least one lumen opening at the distal end of the shaft member; and a lighting arrangement including a fiber optic cable configured to deliver light at the distal end of the fiber optic cable, the fiber optic cable positioned within the at least one lumen.

2 . The surgical device of claim 1 , wherein the at least one lumen is an aspiration lumen and includes an aspiration lumen opening at the distal end of the shaft member.

3 . The surgical device of claim 2 , wherein an aspiration tubing is connected to a proximal end of the surgical device, a proximal end of the aspiration tubing configured to be operatively connected to a vacuum generator, a distal end of the aspiration tubing being operatively connected to the aspiration lumen.

4 . The surgical device of claim 3 , further comprising a connector element positioned between the aspiration lumen and the vacuum generator.

5 . The surgical device of claim 4 , wherein the connector element is a Y-connector having a first arm and a second arm that interests the first arm, wherein the fiber optic cable is introduced through the second arm to the aspiration lumen.

6 . The surgical device of claim 5 , wherein the second arm further comprises a normally closed valve element therein.

7 . The surgical device of claim 5 , further comprising a sealing adapter positioned proximal of the connector element, wherein the fiber optic cable extends through the sealing adapter and the sealing adapter is selectively operable to fix the fiber optic cable to the sealing adapter.

8 . The surgical device of claim 7 , wherein the sealing adapter is a Tuohy Borst fitting.

9 . The surgical device of claim 1 , further comprising a light element, the light element including a housing that houses a light source, wherein the fiber optic cable extends from the light source.

10 . The surgical device of claim 9 , further comprising a heat sink and a cage surrounding the heat sink, wherein the heat sink is configured to absorb heat created by the light source.

11 . The surgical device of claim 9 , wherein the housing further comprises a connector that operatively connects to a connector element, wherein the connector element is secured to a portion of the at least one lumen.

12 . The surgical device of claim 1 , wherein the at least one lumen is an irrigation lumen and includes an irrigation lumen opening at the distal end of the shaft member.

13 . The surgical device of claim 12 , wherein the light delivery arrangement comprises a light housing that houses a light member and the fiber optic fiber extends from the light member and a guide tubing that is operatively positioned within the surgical device, the fiber optic being delivered to the irrigation lumen through the guide tube.

14 . The surgical device of claim 13 , further comprising a connection fitting and a mating connector, wherein the connection fitting is secured to the light housing and the mating connector is connected to the connection fitting.

15 . The surgical device of claim 14 , wherein the guide tube is fixed within the mating connector such that when the mating connector is attached to the connection fitting, the fiber optic is directed into the guide tubing.

16 . The surgical device of claim 15 , wherein the connection fitting is a Tuohy Borst fitting.

17 . The surgical device of claim 13 , wherein the surgical device further comprises an opening formed therein and a cap member that is disposed within the opening, wherein the cap member further comprises a directional channel into which the guide tube is disposed.

18 . The surgical device of claim 17 , wherein the direction channel includes a first aperture and a second aperture and an entry point disposed therebetween, wherein sidewalls of the direction channel are angled inwardly from the first aperture to the entry point.

19 . The surgical device of claim 17 , wherein the directional channel opens into an irrigation chamber of the surgical device and wherein the irrigation lumen includes an open section into which the guide tube enters the irrigation lumen such that the fiber optic is directed into the irrigation lumen from the guide tube.

20 . The surgical device of claim 1 , wherein the diameter of the fiber optic cable is smaller than the diameter of the at least one lumen.
