Abstract
An illuminated suction apparatus including a hand-held surgical device combining a high-performance illumination waveguide with suction. This device would be useful in a wide array of various surgical procedures including open and minimally invasive orthopedics.
Claims20
A surgical device, comprising:
- a suction tube having a proximal end, a distal end, and a central portion extending between the proximal end and the distal end;
- an inner optical cladding surrounding the suction tube;
- an optical waveguide coupled to the suction tube with the inner optical cladding between the optical waveguide and the suction tube, wherein the optical waveguide has a proximal portion and a distal portion, wherein the optical waveguide is configured to transmit light from the proximal portion to the distal portion by total internal reflection;
- and
- an outer optical cladding coupled to the optical waveguide, wherein the outer optical cladding surrounds the optical waveguide, the inner optical cladding, and the suction tube,
- wherein a distal portion of the suction tube extends distally from a distalmost end of the inner optical cladding, a distalmost end of the outer optical cladding, and a distalmost end of the optical waveguide.

A method of forming a surgical device, comprising:
- providing a suction tube having a proximal end, a distal end, and a central portion extending between the proximal end and the distal end;
- coupling an inner optical cladding to the suction tube such that the inner optical cladding surrounds the central portion of the suction tube;
- coupling an optical waveguide to the suction tube with the inner optical cladding between the optical waveguide and the suction tube, wherein the optical waveguide has a proximal portion and a distal portion, wherein the optical waveguide is configured to transmit light from the proximal portion to the distal portion by total internal reflection;
- and
- coupling an outer optical cladding to the optical waveguide, wherein the outer optical cladding surrounds the optical waveguide, the inner optical cladding, and the suction tube,
- wherein a distal portion of the suction tube extends distally from a distalmost end of the inner optical cladding, a distalmost end of the outer optical cladding, and a distalmost end of the optical waveguide.
