Abstract

A retractor for use in surgical operations comprises a pair of blade assemblies. In operation, the blade assemblies are initially in a closed position to assume a low profile, inserted into a relatively small incision, and stretched apart from each other, thereby stretching the skin about the incision to form an aperture longer than the incision. The retractor is adapted to rotate a first blade about a first axis and a second blade about a second axis. The retractor is adapted to move the pair of blade assemblies apart along a third axis. The retractor is adapted to pivot the first blade about a fourth axis and the second blade about a fifth axis. In some embodiments, a method of performing an operation, e.g. a spinal operation, on a patient using the disclosed retractor is provided.

Claims (35)

1. A retractor comprising:

a first blade,

a first rotation mechanism configured to rotate the first blade,

a second blade,

a second rotation mechanism configured to rotate the second blade, wherein the first rotation mechanism and the second rotation mechanism are configured to rotate the first blade and the second blade independently, and

a third blade, wherein the third blade comprises a longitudinally extending slot configured to receive a probe, wherein longitudinal axes of the first blade, the second blade, and the third blade are aligned on substantially the same or the same plane in a closed position.

2. The retractor of claim 1 , further comprising the probe.

3. The retractor of claim 2 , wherein the probe comprises a triangular tip.

4. The retractor of claim 2 , wherein the probe comprises an electrode.

5. The retractor of claim 2 , wherein the probe comprises a passageway configured to receive a guide wire.

6. The retractor of claim 1 , wherein the third blade is removable.

7. The retractor of claim 1 , wherein at least one blade is bent or beveled in order to enhance the ability of the first blade, the second blade, and the third blade to lie flat when the first blade, the second blade, and the third blade are in a closed position.

8. The retractor of claim 1 , wherein the third blade is configured to remain stationary during movement of the first blade and the second blade.

9. The retractor of claim 1 , wherein the third blade is configured to be lowered relative to the probe.

10. A retractor comprising:

a first blade,

a first rotation mechanism configured to rotate the first blade,

a second blade,

a second rotation mechanism configured to rotate the second blade, and

a third blade, wherein the third blade comprises a longitudinally extending slot configured to receive a probe, wherein longitudinal axes of the first blade, the second blade, and the third blade are aligned on substantially the same or the same plane in a closed position.

11. The retractor of claim 10 , wherein the third blade is configured to encircle the probe.

12. The retractor of claim 10 , wherein the length of the probe is greater than the length of the third blade.

13. The retractor of claim 10 , wherein the width of the probe is less than the width of the third blade.

14. The retractor of claim 10 , further comprising the probe.

15. A retractor comprising:

a first blade,

a first pivot mechanism configured to pivot the first blade,

a second blade,

a second pivot mechanism configured to pivot the second blade, and

a third blade, wherein the third blade comprises a longitudinally extending slot configured to receive a probe, wherein longitudinal axes of the first blade, the second blade, and the third blade are aligned on substantially the same or the same plane in a closed position.

16. The retractor of claim 15 , wherein the third blade comprises a substantially flat blade.

17. The retractor of claim 15 , further comprising a third pivot mechanism configured to pivot the third blade.

18. The retractor of claim 15 , wherein the probe is configured to be inserted into a distal tip of the third blade.

19. The retractor of claim 15 , wherein the probe comprises an oval cross-section.

20. The retractor of claim 15 , further comprising the probe.
