Abstract

Improved methods and apparatus render ADR insertion safer and more precise. Certain surgical instruments according to the invention include a level enabling a user to align the instrument for proper placement of a surgical implant. A different surgical instrument includes two or more scopes mounted relative to the instrument permitting a user to simultaneously view more than one side of the instrument. A device for use with a surgical instrument having a long shaft includes a holder that surrounds at least a portion of the shaft allowing a user to control the instrument with both hands. A further surgical instrument comprises a set of retractors and one or more guards placed over the retractors for protecting the great vessels, nerves or other delicate structures during a surgical procedure. Surgical apparatus according to the invention comprises a platform mountable to an operating room table over a patient undergoing a surgical procedure, enabling a user to place their hands or attach an instrument while operating. Different surgical instruments include an indicator showing angular displacement or a wedge-shaped portion used for disc distraction. Also disclosed are blades designed for use with a power tool featuring a cutting edge configured such that rapid oscillation of the cutting tool reduces the pressure a user must apply the tool.

Claims

1. A surgical instrument, comprising:

a level enabling a user to orient the instrument in space for proper placement of a surgical implant.

2. The instrument of claim 1, wherein the implant is an artificial disc replacement (ADR).

3. The instrument of claim 1, wherein the implant forms parts of a total joint replacement.

4. A surgical instrument, comprising:

two or more viewing scopes mounted relative to the instrument permitting a user to simultaneously view more than one side of the instrument.

5. The surgical instrument of claim 4, wherein the instrument comprises a set of retractors.

6. A device for use with a surgical instrument having a long shaft, comprising:

a holder that surrounds at least a portion of the shaft allowing a user to control the instrument with both hands.

7. A surgical instrument, comprising:

a set of retractors; and

one or more guards placed over the retractors for protecting the great vessels, nerves or other delicate structures during a surgical procedure.

8. The surgical instrument of claim 7, including differently shaped guards for different spinal levels.

9. Surgical apparatus, comprising:

a platform mountable to an operating room table over a patient undergoing a surgical procedure, enabling a user to place their hands or attach an instrument while operating.

10. The surgical apparatus of claim 9, wherein the instrument is a retractor.

11. The surgical apparatus of claim 9, wherein the instrument is a guide to control the movement of a tool.

12. A surgical instrument, comprising:

an indicator showing angular displacement.

13. A surgical instrument, comprising:

a wedge-shaped portion used for disc distraction.

14. A blade designed for use with a power tool, comprising:

a cutting edge configured such that rapid oscillation of the cutting tool reduces the pressure a user must apply the tool.
