Abstract

A sterile adaptor is provided. The adaptor includes a housing, a retractor plate assembling, and a disc. The retractor plate assembly is coupled to the housing and includes a spring plate between upper and lower retractor plates. The spring plate includes an aperture with leaves. The disc is movably coupled to the spring plate of the retractor plate assembly, with a first side of the disc couplable to a surgical instrument and a second side of the disc couplable to a manipulator arm of a robotic surgical system. The disc is capable of transmitting torque from the manipulator arm to the surgical instrument.

First claim

I claim:

1. A surgical system, comprising:
a sterile adaptor including:
a housing;
a retractor plate assembly coupled to the housing, the retractor plate assembly including a spring plate between an upper retractor plate and a lower retractor plate, the spring plate including an aperture with leaves; and
a disc movably coupled to the spring plate of the retractor plate assembly, a first side of the disc couplable to a surgical instrument, and a second side of the disc couplable to a manipulator arm of a robotic surgical system, the disc capable of transmitting torque from the manipulator arm to the surgical instrument.

2. The surgical system of claim 1 further comprising a sterile drape couplable to the sterile adaptor.

3. The surgical system of claim 2 wherein the sterile drape is comprised of a material selected from the group consisting of polyethylene, polyurethane, and polycarbonate.

4. The surgical system of claim 2 wherein a portion of the sterile drape is sandwiched between the upper and lower retractor plates.

5. The surgical system of claim 1 wherein the disc includes a channel sized to receive the leaves.

6. The surgical system of claim 1 wherein the upper retractor plate includes a plurality of posts and the lower retractor plate includes a plurality of receiving apertures, each sized to receive one of the plurality of posts.

7. The surgical system of claim 1 wherein the upper retractor plate includes a plurality of posts and the spring plate includes a plurality of receiving apertures, each sized to receive one of the plurality of posts.

8. The surgical system of claim 7 wherein the plurality of receiving apertures are arranged around a circumference of the aperture with leaves.

9. The surgical system of claim 1 further comprising the surgical instrument.

10. The surgical system of claim 1 further comprising the manipulator arm.

11. A surgical system, comprising:
a sterile adaptor including:
a housing;
a retractor plate assembly coupled to the housing, the retractor plate assembly including a spring plate between an upper retractor plate and a lower retractor plate, the spring plate including an aperture with leaves;
a disc movably coupled to the spring plate of the retractor plate assembly, a first side of the disc couplable to a surgical instrument, and a second side of the disc couplable to a manipulator arm of a robotic surgical system, the disc capable of transmitting torque from the manipulator arm to the surgical instrument; and
an integrated circuit providing an encrypted key for authentication of the sterile adaptor.

12. The surgical system of claim 11 further comprising a sterile drape couplable to the sterile adaptor.

13. The surgical system of claim 12 wherein the sterile drape is comprised of a material selected from the group consisting of polyethylene, polyurethane, and polycarbonate.

14. The surgical system of claim 12 wherein a portion of the sterile drape is sandwiched between the upper and lower retractor plates.

15. The surgical system of claim 11 wherein the disc includes a channel sized to receive the leaves.

16. The surgical system of claim 11 wherein the upper retractor plate includes a plurality of posts and the lower retractor plate includes a plurality of receiving apertures, each sized to receive one of the plurality of posts.

17. The surgical system of claim 11 wherein the upper retractor plate includes a plurality of posts and the spring plate includes a plurality of receiving apertures, each sized to receive one of the plurality of posts.

18. The surgical system of claim 17 wherein the plurality of receiving apertures are arranged around a circumference of the aperture with leaves.

19. The surgical system of claim 11 wherein the integrated circuit provides for one of presence notification of the adaptor and identification data of a mounted instrument.

20. The surgical system of claim 11 further comprising an electrostatic protective cover over the integrated circuit.
