Abstract

A method for removing a vein includes making an incision through a skin layer of a patient, inserting a surgical instrument through the incision, visualizing the vein through the skin layer using a light source positioned subcutaneously and in proximity of the vein, and cutting the vein using the surgical instrument. The vein can be visualized by directing light from the light source at the vein from underneath the vein or from a side of the vein.
A device for illuminating a body structure has a housing with a distal end configured for subcutaneous insertion into a patient's tissue and positioning in proximity of the body structure, a light path supported by the housing and configured for directing light at the body structure, and a fluid line supported by the housing.

Claims (30)

1. A method for removing a vein, comprising:
making an incision through a skin layer of a patient, inserting a surgical instrument through the incision, visualizing the vein through the skin layer using a light source positioned subcutaneously and in proximity of the vein, and cutting the vein using the surgical instrument.
2. The method of claim 1 wherein visualizing the vein includes directing light from the light source at the vein from underneath the vein.
3. The method of claim 1 wherein visualizing the vein includes directing light from the light source at the vein from a side of the vein.
4. The method of claim 1 wherein visualizing the vein includes providing the surgical instrument with the light source.
5. The method of claim 1 wherein the light source comprises a fiberoptic.
6. The method of claim 5 wherein the fiberoptic comprises a fiberoptic bundle.
7. The method of claim 1 further comprising irrigating a surgical region in proximity to the vein using the surgical instrument.
8. The method of claim 1 further comprising tumescing a surgical region in proximity to the vein using the surgical instrument.
9. The method of claim 1 further comprising aspirating cut veinous tissue through the surgical instrument.
10. The method of claim 1 wherein visualizing the vein comprises providing a second instrument including the light source, making a second incision through a skin layer of the patient, and inserting the second instrument through the incision.
11. The method of claim 10 further comprising irrigating a surgical region in proximity to the vein using the second instrument.
12. The method of claim 10 further comprising tumescing a surgical region in proximity to the vein using the second instrument.
13. A method for removing a vein, comprising:
making a first incision through the skin layer of a patient, making a second incision through the skin layer of the patient, inserting an illuminating device through the first incision, inserting a cutting instrument through the second incision, visualizing the vein through the skin layer by positioning the illuminating device in proximity of the vein, cutting the vein using the cutting instrument, and aspirating cut tissue through the cutting instrument.
14. A method of visualizing a body structure, comprising:
positioning an illuminating device subcutaneously such that light is directed at the body structure, and observing the body structure through a skin layer of the patient overlying the body structure.
15. The method of claim 14 wherein visualizing the body structure includes directing light from the illuminating device at the body structure from underneath the body structure.
16. The method of claim 14 wherein visualizing the body structure includes directing light from the illuminating device at the body structure from a side of the body structure.
17. Surgical device for insertion into a body structure, comprising: a housing having proximal and distal ends, the distal end being configured for subcutaneous insertion into a patient's tissue and positioning in proximity of the body structure; and a light path supported by or within the housing configured for directing light at the body structure.
18. Surgical device according to claim 17, additionally comprising a fluid path supported by or within the housing.
19. Surgical device according to claim 18, wherein the fluid path is suitable for directing fluid to the distal end of the housing.
20. Surgical device according to claim 18 or 19, wherein the housing comprises a fluid connector for attaching an input fluid line.
21. Surgical device according to claim 17 to 20, wherein the housing comprises a light path connector for connecting the light path to a light transmitter.
22. Surgical device according to claim 21, wherein the light path connector extends from the proximal end of the housing substantially in the direction of a longitudinal axis of the housing.
23. Surgical device according to any one of claims 17 to 22, wherein the light path comprises a fiberoptic illuminating device.
24. Surgical device according to claim 23, wherein the fiberoptic illuminating device comprises a fiberoptic cable or a bundle comprising a plurality of fiberoptic cables.
25. Surgical device according to any one of claims 17 to 24, wherein the distal end comprises a surgical tool.
26. Surgical device according to any one of claims 17 to 24, wherein the surgical tool comprises a cutter.
27. Surgical device according to claim 26, wherein the housing comprises an outer tube defining a lumen; an inner tube located within the outer tube, the inner tube including the cutter and being movable relative to the outer tube to cut tissue, the light path being configured for directing light at a region adjacent the cutter.
28. Surgical device according to claim 27, wherein the inner tube defines an aspiration path.
29. Surgical device according to claim 27 or 28, wherein the inner tube and outer tube define the fluid path therebetween.
30. Surgical device according to either of claims 27 or 28, wherein the inner tube is configured to rotate at a speed of about 500-2000 rpm.
