Disposable sterile surgical adaptor
A sterile adaptor, a sterile drape with the integrated sterile adaptor, and a telerobotic surgical system including the sterile drape are provided. The adaptor, drape, and system allow for draping portions of a telerobotic surgical system to maintain a sterile barrier between the sterile surgical field and the non-sterile robotic system while also providing an interface for transferring mechanical and electrical energy and signals between a robotic arm and a surgical instrument in the sterile field.

6. The sterile adaptor of claim 1 , further comprising an electrostatic protective cover over the integrated circuit.
7. A sterile drape to cover a non-sterile portion of a robotic surgical system, the sterile drape comprising:
an exterior surface adjacent to a sterile field for performing a surgical procedure;
an interior surface adjacent to the non-sterile portion of the robotic surgical system; and
a sterile adaptor for interfacing between a non-sterile manipulator arm of the robotic surgical system and a sterile surgical instrument in the sterile field, the sterile adaptor including:
a housing for receiving the surgical instrument;
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 the 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;
an electrical contact that provides electrical connectivity between the manipulator arm and the surgical instrument; and
an integrated circuit operably coupled to the electrical contact, the integrated circuit providing an encrypted key for authentication of the drape.
8. The sterile drape of claim 7 , wherein the drape is comprised of a material selected from the group consisting of polyethylene, polyurethane, polycarbonate, and similar elastic durable materials.
9. The sterile drape of claim 7 , wherein the electrical contact is positioned at an angle relative to a horizontal plane of the housing.
10. The sterile drape of claim 7 , wherein the electrical contact includes a break that delays electrical engagement of the instrument with the adaptor.
11. The sterile drape of claim 7 , wherein the integrated circuit further provides for one of presence notification of the adaptor and identification data of a mounted instrument.
12. The sterile drape of claim 7 , wherein the encrypted key further provides adaptor presence notification to the robotic surgical system.
13. A robotic surgical system for performing a procedure within a sterile field, the system comprising:
a manipulator arm in a non-sterile field;
a surgical instrument in the sterile field; and
a sterile drape covering the manipulator arm to shield the manipulator arm from the sterile field, the sterile drape having a sterile adaptor including:
a housing for receiving the surgical instrument;
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 the 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;
an electrical contact that provides electrical connectivity between the manipulator arm and the surgical instrument; and
an integrated circuit operably coupled to the electrical contact, the integrated circuit providing an encrypted key for authentication of the drape.
14. The system of claim 13 , wherein the electrical contact is positioned at an angle relative to a horizontal plane of the housing.
15. The system of claim 13 , wherein the electrical contact includes a break that delays electrical engagement of the instrument with the adaptor.
16. The system of claim 13 , wherein the integrated circuit further provides for one of presence notification of the adaptor and identification data of a mounted instrument.
17. The system of claim 13 , wherein the encrypted key further provides adaptor presence notification to the robotic surgical system.
18. The system of claim 13 , wherein the surgical instrument is selected from the group consisting of articulated tools with end effectors, such as jaws, scissors, graspers, needle holders, micro-dissectors, staple appliers, tackers, and clip appliers, and non-articulated tools, such as cutting blades, cautery probes, irrigators, catheters, and suction orifices.
