Abstract

An electrosurgical electrode configured for use in a breast plastic surgical procedure comprises an elongated forceps that is operated as a unipolar electrode. The electrosurgical electrode is provided with internal channels that can provide suction or fluids at the surgical site when a source of suction or fluid is connected to the electrode. It is provided with uniquely configured cutting edges at its distal end for cutting tissue while simultaneously coagulating any bleeding that occurs. It can cleanly and precisely cut tissue and coagulate bleeding vessels at the same time.

Claims

1. An electrosurgical unipolar electrode in the form of forceps for breast tissue surgery, comprising:

a) an elongated body extending in a longitudinal direction and comprising first and second arms connected at a first end for removably attaching to electrosurgical apparatus and laterally spaced apart at a second end, the first and second arms having inner surfaces facing one another,

b) each of said first and second arms having at their second end an active electrosurgical bare end capable of supplying electrosurgical currents to tissue when the electrode is connected to electrosurgical apparatus and the latter activated,

c) the electrosurgical bare end of each of the arms comprising a metal end having a triangular cross-section with first vertices of the triangular metal ends located on the outside of each of the bare ends and forming opposed sharp edges extending forwardly in the longitudinal direction of the elongated body such that the sharp edges of the elongated body can cut or dissect tissue when both arms are moved laterally,

d) the remainder of the body back of the bare ends having a protective electrically-insulating surface,

e) a first tubular member mounted on the inner surface of the first arm and extending near to the active electrosurgical end of the first arm and terminating in an open port at that end,

f) means connected to the first arm for supplying suction to the first tubular member.

2. An electrosurgical electrode as set forth in claim 1, wherein the triangular cross-section of the electrosurgical bare end of each of the arms comprises second vertices of the triangular metal ends facing each other.

3. An electrosurgical electrode as set forth in claim 1, wherein each of triangular metal ends is oriented such that the second vertices lie in the same plane, and such that the second vertices form cutting edges when the arms are brought together.

4. An electrosurgical electrode as set forth in claim 1, wherein the open port at the end of the first tubular member is located on the inside of the first arm before the first vertices of the triangular metal ends is reached.

5. An electrosurgical electrode as set forth in claim 1, further comprising electrical connector means at the first end of the elongated body for connection to the electrosurgical apparatus, the electrical connection means being electrically connected to the first and second arms, the means for supplying suction comprising a first fitting for a suction tube mounted to the outside of the first arm before the electrical connection means and extending obliquely to the elongated direction and connected to the first tubular member.

6. An electrosurgical electrode as set forth in claim 5, further comprising a second tubular member mounted on the inner surface of the second arm and extending near to the active electrosurgical end of the first arm and terminating in an open port at that end located on the inside of the second arm before the first vertices of the triangular metal ends is reached.

7. An electrosurgical electrode as set forth in claim 6, further comprising a second fitting for an irrigation tube mounted to the outside of the second arm before the electrical connection means and extending obliquely to the elongated direction and connected to the second tubular member.

8. An electrosurgical electrode as set forth in claim 1, wherein the first tubular member has two spaced openings at its end.

9. An electrosurgical electrode as set forth in claim 1, wherein the overall length of the body is about 230–

210 mm.

10. An electrosurgical electrode as set forth in claim 1, wherein the triangular metal end has a side length of about 1.8–

3 mm, and a height of about 1.3–

2.3 mm.

11. In combination:

i) an electrosurgical unipolar electrode in the form of forceps for breast tissue surgery, comprising;

a) an elongated body extending in a longitudinal direction and comprising first and second arms connected at a first end for removably attaching to electrosurgical apparatus and laterally spaced apart at a second end, the first and second arms having inner surfaces facing one another,

b) each of said first and second arms having at their second end an active electrosurgical bare end capable of supplying electrosurgical currents to tissue when the electrode is connected to electrosurgical apparatus and the latter activated,

c) the electrosurgical bare end of each of the arms comprising a metal end having a triangular cross-section with first vertices of the triangular metal ends located on the outside of each of the bare ends and forming opposed sharp edges extending forwardly in the longitudinal direction of the elongated body such that the sharp edges of the elongated body can cut or dissect tissue when both arms are moved laterally,

d) the remainder of the body back of the bare ends having a protective electrically-insulating surface,

e) a first tubular member mounted on the inner surface of the first arm and extending near to the active electrosurgical end of the first arm and terminating in an open port at that end,
