Abstract

An electrosurgical implement ( 10; 110 ) is provided comprising a first arm ( 12 a ; 112 a ) having a first rigid body ( 30 a ; 130 a ) and a first conductive element ( 44 a ; 144 a ) including a first electrosurgical tip ( 26 a ; 126 a ) extending from a first axial tip end ( 24 a ; 124 a ) of the first rigid body ( 30 a ; 130 a ), the first rigid body ( 30 a ; 130 a ) comprising a first inner portion ( 36 a ; 136 a ) and a first outer portion ( 38 a ; 138 a ) connectable about the first conductive element ( 44 a ; 144 a ). There is also a corresponding second arm ( 12 b ; 112 b ) which is preferably identical to the first arm ( 12 a ; 112 a ). The second arm ( 12 b ; 112 b ) is movably connected to the first arm ( 12 a ; 112 a ) and there is also a biasing means for providing a separating force between the first and second arms ( 12 a , 12 b ; 112 a , 112 b ).

a biasing means for providing a separating force between the first and second arms,

wherein the first and second rigid bodies of the first and second arms have identical shapes to one another, and wherein each of the first and second rigid bodies of the first and second arms have an asymmetric profile in a tweezing plane of the electrosurgical implement.

2 . The electrosurgical implement as claimed in claim 1 , wherein the first and second rigid bodies are made of an insulating material.

3 . The electrosurgical implement as claimed in claim 1 , wherein the biasing means comprises a spring member.

4 . (canceled)

5 . The electrosurgical implement as claimed in claim 3 , wherein the spring member comprises at least one sprung hinge between the first and second arms.

6 . The electrosurgical implement as claimed in claim 1 , wherein the first and second rigid bodies of the first and second arms have identical shapes to one another.

7 . The electrosurgical implement as claimed in claim 1 , wherein each of the first and second rigid bodies of the first and second arms have an asymmetric profile in a tweezing plane of the electrosurgical implement.

8 . (canceled)

9 . The electrosurgical implement as claimed in claim 1 , wherein the first conductive element is located between the first inner portion and the first outer portion and wherein the second conductive element is located between the second inner portion and the second outer portion.

10 . The electrosurgical implement as claimed in claim 1 , wherein the first inner portion comprises a first electrosurgical tip support at the first axial tip end of the first rigid body to receive the first electrosurgical tip and wherein the second inner portion comprises a second electrosurgical tip support at the second axial tip end of the second rigid body to receive the second electrosurgical tip.

11 . The electrosurgical implement as claimed in claim 1 , wherein the first inner portion and/or the first outer portion of the first arm includes a locator for receivably engaging with the first conductive element, and the second inner portion and/or the second outer portion of the second arm includes a locator for receivably engaging with the second conductive element.

12 . The electrosurgical implement as claimed in claim 1 , wherein the first rigid body comprises at least one first retaining member and the second rigid body comprises at least one second retaining member, the at least one first retaining member being interengagable with the at least one second retaining member to inhibit displacement of first and second electrosurgical tips out of a tweezing plane of the electrosurgical implement.

13 . The electrosurgical implement as claimed in claim 12 , wherein a plurality of said first retaining members and/or a plurality of said second retaining members is provided, the said first and second retaining members interleaving with one another to inhibit displacement of first and second electrosurgical tips out of a tweezing plane of the electrosurgical implement.

14 . The electrosurgical implement as claimed in claim 1 , further comprising a smoke evacuation tube positioned between the first and second arms, wherein the first rigid body comprises two first retaining members and the second rigid body comprises two second retaining members, the two first retaining members and two second retaining members being interengagable with the smoke evacuation tube to inhibit displacement of first and second electrosurgical tips out of a tweezing plane of the electrosurgical implement.

15 . (canceled)

16 . The electrosurgical implement as claimed in claim 1 , further comprising a switch associated with at least one of the first and second arms for activating a current applied to the first and second electrosurgical tips.

17 . The electrosurgical implement as claimed in claim 1 , further comprising a conductor carrying portion engagable with the first and second arms.

18 . The electrosurgical implement as claimed in claim 17 , wherein at least one of the first and second arms is movable relative to the conductor carrying portion, and wherein the conductor carrying portion includes at least one stop abuttably engagable with the first and/or second arm to limit movement of the first and/or second arm by the biasing means.

19 . The electrosurgical implement as claimed in claim 17 , further comprising an electrically conductive wire supported by the conductor carrying portion for providing a current to the first and second electrosurgical tips from an external power supply, where the electrically conductive wire comprises a first wire branch and a second wire branch, the first and second wire branches respectively connecting to the first and second conductive elements.

20 . (canceled)

21 . The electrosurgical implement as claimed in claim 1 , wherein the first arm comprises a first hinge barrel, and the second arm comprises a second hinge barrel.

22 . The electrosurgical implement as claimed in claim 21 , wherein the first inner portion and/or the first outer portion of the first arm includes a locator for receivably engaging with the first conductive element, and the second inner portion and/or the second outer portion of the second arm includes a locator for receivably engaging with the second conductive element, and wherein the first hinge barrel is integrally formed with the or each first retaining member, and the second hinge barrel is integrally formed with the or each second retaining member.
