Abstract

This invention relates to an electrosurgical device having a hollow shaft, an electrically conductive distal tip that is also adapted for penetrating bone, and an intermediate electrically insulating spacer.

Claims

1. An electrosurgical device, comprising:

a hollow shaft made of an electrically conductive material having an annular wall having a longitudinal bore therein, a proximal portion and a distal portion, and a first window extending transversely through the annular wall; and

a first electrode disposed within the window and being in electrical connection with a power supply.

2. An electrosurgical device, comprising:

a hollow shaft having an annular wall having a longitudinal bore therein, a proximal portion and a distal portion, and a first window extending transversely through the annular wall;

an active electrode disposed within the window and being in electrical connection with a power supply, and

a return electrode disposed within the window and being in electrical connection with the power supply.
