Electrosurgical instrument for therapeutic treatment of varices
First Claim
1. Electrosurgical instrument for the therapy of varices, comprisingtwo fork-shaped protruding needle electrodes (6, 7), which are connectable to different poles of an electrical current source and which each are partly coated by a thin electrical insulation layer, said insulation layer leaving a forward tip zone (6a, 7a) of the needle electrodes (6, 7) free, whereby the transition from the tip zone to an insulated zone is substantially stepless;
- andthe needle electrodes (6,
7) are axially supported at a rearward end in insulating sleeves (4,
5) having a larger cross section than the needle electrodes (6,
7).

Abstract
An electrosurgical instrument is useful for therapeutic treatment of varices, especially small varicose dilatations of the cutaneous veins. A surgical instrument is provided for rapid, reliable and minimally discomforting therapy of small varicose dilatations of the cutaneous veins and similar disorders, ensuring the lowest possible rate of recidivism while minimizing side effects. The instrument has two fork-shaped protruding needle electrodes which connect to different poles of an electrical power source and which are each partially enclosed in an electrical insulating layer. The forward tip region of the needle electrodes is left open.
