Method for making bi-polar electrocautery needle

摘要

A bi-polar electrocautery needle comprising an inner electrode, an outer electrode and recoverable insulating-locking means for insulating the electrodes from one another and locking them into relative position to one another. And the method of making the bi-polar electrocautery needle in accordance with this invention, the steps including: expanding recoverable dielectric material over an inner electrode; inserting the combination into an outer electrode, and recovering the material between the electrodes for insulating and locking the electrodes into relative position with one another.
