Abstract
A combination aspiration/irrigation and illumination device using optical fibers circumferentially disposed around the aspiration conduit for transmitting illuminating light to a cavity to be aspirated. The ends of the optical fibers being formed at an angle relative to the aspiration conduit so as to direct the illuminating light inward to provide intensified illumination ahead of the aspiration conduit.
Claims7
A medical instrument for providing illuminating light to and aspiration of a cavity, the device comprising:
- an aspiration conduit for aspirating fluid and particles from the cavity;
- a valve coupled to said aspiration conduit;
- an aspirator coupled to said valve;
- a fluid source coupled to said valve;
- a switch connected to said valve;
- wherein said valve may selectively be switched to fluidly couple between said aspirator and said aspiration conduit or said fluid source and said aspiration conduit;
- and
- a plurality of optical fibers coupled to a light source and circumferentially positioned surrounding said aspiration conduit for transmitting illuminating light to the cavity
- an illuminating light source coupled to said plurality of optical fibers;
- wherein illuminating light exits a distal end of said plurality of optical fibers and illuminates an area ahead of the distal end of said plurality of optical fibers and wherein the illuminating light comprises and energy level that will not damage surrounding tissue in which it comes into contact with.
