Abstract

An orthopedic surgery system includes: a retractor support arm; a table mounting assembly for securing the retractor support arm to the operating table; a first blade mounting arm slidably engaging the retractor support arm; a second blade mounting arm slidably engaging the retractor support arm in spaced relationship with respect to the first blade mounting arm; a first retractor blade connected to the first blade mounting arm; a second retractor blade connected to the second blade mounting arm; and a plate support assembly for releasably engaging an orthopedic plate wherein the plate support assembly slidably engages at least one of the retractor support arm or the first blade mounting arm or the second blade mounting arm. In one version of the invention, the system used in anterior cervical spine surgery and the orthopedic plate is an anterior cervical plate.

Claims (59)

1. A retractor system for surgery on a patient positioned on an operating table, the system comprising:

a retractor support arm;

a table mounting assembly for securing the retractor support arm to the operating table;

a first blade mounting arm slidably engaging the retractor support arm, the first blade mounting arm defining a longitudinal axis of the first blade mounting arm;

a second blade mounting arm slidably engaging the retractor support arm in spaced relationship with respect to the first blade mounting arm, the second blade mounting arm defining a longitudinal axis of the second blade mounting arm;

a first retractor blade integrally connected to the first blade mounting arm such that the first retractor blade is not removably connected to the first blade mounting arm and such that the first retractor blade is non-rotatably fixed orthogonal to the longitudinal axis of the first blade mounting arm; and

a second retractor blade connected to the second blade mounting arm such that the second retractor blade is non-rotatably fixed orthogonal to the longitudinal axis of the second blade mounting arm,

wherein the first blade mounting arm and the second blade mounting arm can be moved away from each other and secured on the retractor support arm such that the first retractor blade and the second retractor blade hold back soft tissues of the patient on opposite sides of a surgical incision in the patient.

2. The system of claim 1 wherein:

the table mounting assembly includes a clamp for securing the retractor support arm to the operating table.

3. The system of claim 2 wherein:

the clamp is structured to secure the retractor support arm to a side rail of the operating table.

4. The system of claim 1 wherein:

the first retractor blade has a width of 30 millimeters to 105 millimeters and a longitudinal length of 30 millimeters to 75 millimeters, and

the second retractor blade has a width of 30 millimeters to 105 millimeters and a longitudinal length of 30 millimeters to 75 millimeters.

5. The system of claim 1 wherein:

the first retractor blade has a first section connected to the first blade mounting arm and has a second section that extends laterally from the first section of the first retractor blade, and

the second retractor blade has a first section connected to the second blade mounting arm and has a second section that extends laterally from the first section of the second retractor blade.

6. The system of claim 5 wherein:

the second section of the first retractor blade extends laterally from the first section of the first retractor blade at an angle of 45 to 60 degrees with respect to a top edge of the first section of the first retractor blade, and

the second section of the second retractor blade extends laterally from the first section of the second retractor blade at an angle of 45 to 60 degrees with respect to a top edge of the first section of the second retractor blade.

7. The system of claim 1 further comprising:

a first fastener for securing the first blade mounting arm on the retractor support arm to prevent sliding movement of the first blade mounting arm on the retractor support arm; and

a second fastener for securing the second blade mounting arm on the retractor support arm to prevent sliding movement of the second blade mounting arm on the retractor support arm.

8. A system for orthopedic surgery on a patient positioned on an operating table, the system comprising:

a retractor support arm;

a table mounting assembly for securing the retractor support arm to the operating table;

a first blade mounting arm slidably engaging the retractor support arm;

a second blade mounting arm slidably engaging the retractor support arm in spaced relationship with respect to the first blade mounting arm;

a first retractor blade integrally connected to the first blade mounting arm such that the first retractor blade is not removably connected to the first blade mounting arm and such that the first retractor blade is non-rotatably fixed to the first blade mounting arm;

a second retractor blade connected to the second blade mounting arm such that the second retractor blade is non-rotatably fixed to the second blade mounting arm; and

a plate support assembly for releasably engaging an orthopedic plate, the plate support assembly slidably engaging at least one of the retractor support arm or the first blade mounting arm or the second blade mounting arm,

wherein the first blade mounting arm and the second blade mounting arm can be moved away from each other and secured on the retractor support arm such that the first retractor blade and the second retractor blade hold back soft tissues of the patient on opposite sides of a surgical incision in the patient.

9. The system of claim 8 further comprising:

a drill guide; and

a drill guide support assembly for releasably engaging the drill guide, the drill guide support assembly slidably engaging at least one of the retractor support arm or the first blade mounting arm or the second blade mounting arm.

10. The system of claim 8 wherein:

the plate support assembly slidably engages the first blade mounting arm.

11. The system of claim 10 further comprising:

a fastener for securing the plate support assembly to first blade mounting arm to prevent sliding movement of the plate support assembly on the first blade mounting arm.

12. The system of claim 10 wherein:

the orthopedic plate includes a mounting hole, and

the plate support assembly includes a shaft, and

the shaft releasably engages the mounting hole of the orthopedic plate.

13. The system of claim 8 wherein:

the table mounting assembly includes a clamp for securing the retractor support arm to the operating table.

14. The system of claim 13 wherein:

the clamp is structured to secure the retractor support arm to a side rail of the operating table.

15. The system of claim 8 wherein:

the first retractor blade has a width of 30 millimeters to 105 millimeters and a longitudinal length of 30 millimeters to 75 millimeters, and

the second retractor blade has a width of 30 millimeters to 105 millimeters and a longitudinal length of 30 millimeters to 75 millimeters.

16. The system of claim 8 wherein:

the first retractor blade has a first section connected to the first blade mounting arm and has a second section that extends laterally from the first section of the first retractor blade, and

the second retractor blade has a first section connected to the second blade mounting arm and has a second section that extends laterally from the first section of the second retractor blade.

17. The system of claim 16 wherein:

the second section of the first retractor blade extends laterally from the first section of the first retractor blade at an angle of 45 to 60 degrees with respect to a top edge of the first section of the first retractor blade, and

the second section of the second retractor blade extends laterally from the first section of the second retractor blade at an angle of 45 to 60 degrees with respect to a top edge of the first section of the second retractor blade.

18. The system of claim 8 wherein:

the surgery is anterior cervical spine surgery and the orthopedic plate is an anterior cervical plate.
