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.
Claims18
An illuminated electrosurgical instrument, comprising:
- a handle having a proximal end and a distal end;
- an optical waveguide having a proximal end and a distal end, wherein the optical waveguide is adjustably coupled to the handle such that a distance between the distal end of the optical waveguide and the proximal end of the handle is adjustable without decoupling the optical waveguide from the handle, wherein the optical waveguide is telescopically arranged with the handle such that (i) a portion of the optical waveguide telescopes out of the handle when the optical waveguide is adjusted distally relative to the handle and (ii) the portion of the optical waveguide telescopes into the handle when the optical waveguide is adjusted proximally relative to the handle;
- an electrosurgical tip fixedly and non-adjustably coupled to the optical waveguide, wherein the electrosurgical tip is an electrode blade that extends distally from the distal end of the optical waveguide;
- and
- an electrical conducting element disposed around the optical waveguide, wherein the electrical conducting element is configured to provide radiofrequency (rf) energy to the electrosurgical tip.
