Abstract

A blade insert illumination system includes one or more illumination elements composed of a transparent or semitransparent polymer that is preferably biocompatible and sterilizable. The illumination elements operate as a waveguide and may incorporate optical components such as, for example, facets, lenses, gratings, prisms and or diffusers to operate as precision optics for customized delivery of the light energy. The illumination elements may be modular, allowing components to be mixed and matched for different sizes of blade retractors, or may be a single integrated unit.

Claims (25)

1. A modular retractor illumination system comprising:

a blade retractor; and

a blade insert illuminator system releasably coupled with the blade retractor, the blade insert illuminator system including a light input element, at least one light conduit section, and a light output element with one or more light output structures,

wherein the at least one light conduit section is disposed between the light input element and the light output element,

wherein the light input element, at least one light conduit section, and the light output element are releasably engaged together so as to maintain a secure optical connection therethrough, and

wherein at least one releasable engagement is disposed over the blade retractor, and

wherein the at least one light conduit section and a portion of the light output element act as waveguides with light passing therethrough by total internal reflection.

2. The modular retractor illumination system of claim 1 , wherein a detent is formed in the light input element and the at least one light conduit section comprises a latch adapted to releasably engage the detent.

3. The modular retractor illumination system of claim 1 , wherein the at least one light conduit section comprises an engagement structure and the light output element comprises an engagement arm adapted to releasably engage the engagement structure.

4. The modular retractor illumination system of claim 1 ,

wherein the at least one light conduit section comprises a first light conduit section and a second light conduit section, the first light conduit section and the second light conduit section being releasably engaged with one another so as to maintain a secure optical connection therebetween, and

wherein the first light conduit section comprises an engagement structure and the second light conduit section comprises an engagement arm adapted to releasably engage the engagement structure.

5. The modular retractor illumination system of claim 1 , wherein the at least one light conduit section comprises an engagement structure and the light output element comprises an engagement arm adapted to releasably engage the engagement structure.

6. The modular retractor illumination system of claim 1 , wherein a distal portion of the light input element comprises a male engagement member and a proximal portion of the at least one light conduit section comprises a receptacle adapted to releasably capture the male engagement member.

7. The modular retractor illumination system of claim 1 ,

wherein the at least one light conduit section comprises a first light conduit section and a second light conduit section, the first light conduit section and the second light conduit section being releasably engaged with one another so as to maintain a secure optical connection therebetween, and

wherein a distal portion of the first light conduit section comprises a male engagement member and a proximal portion of the second light conduit section comprises a receptacle adapted to releaseably capture the male engagement member.

8. The modular retractor illumination system of claim 1 , wherein a distal portion of the at least one light conduit section comprises a male engagement member and a proximal portion of the light output element comprises a receptacle adapted to releasably capture the male engagement member.

9. The modular retractor illumination system of claim 1 , wherein the blade insert illuminator system is releasably coupled with the blade retractor through a channel formed in the blade retractor.

10. The modular retractor illumination system of claim 1 , wherein the one or more light output structures of the light output element comprise one or more stair stepped facets.

11. The modular retractor illumination system of claim 1 , wherein the one or more light output structures of the light output element comprise one or more lenses.

12. The modular retractor illumination system of claim 1 , wherein the light input element comprises a bifurcated fiber optic cable.

13. The modular retractor illumination system of claim 1 , wherein the light input element comprises an integrated fiber optical cable having a plurality of fiber optic strands.

14. The modular retractor illumination system of claim 1 , wherein the light input element is rotatable relative to the blade retractor when releasably coupled thereto.

15. The modular retractor illumination system of claim 1 , wherein a substantial portion of the light input element is substantially transverse to the blade retractor when releasably coupled thereto.
