## Abstract

An illuminated energy device includes a handle, an optical waveguide coupled to the handle, and an energy tip such as an electrode coupled to the optical waveguide. The optical waveguide is preferably adjustably coupled to the optical waveguide, and adjustment of the optical waveguide moves a distal end of the optical waveguide closer to or further away from a target such as tissue in a surgical field.

## Claims

### Claim 1

An illuminated electrosurgical instrument, said instrument comprising:
a handle;
an optical waveguide coupled to the handle; and
an electrosurgical tip coupled to the optical waveguide.
