Abstract

A number of orthopedic surgical instruments are also disclosed. A method, apparatus, and system for fabricating such instruments are also disclosed.

Claims

1. A method for a vendor to create a customized patient-specific orthopaedic surgical instrument for a patient of a healthcare facility that is external to the vendor, comprising:

receiving at the vendor, from the healthcare facility external to the vendor, an instrument request for a customized patient-specific orthopaedic surgical instrument that includes data relevant to the patient,

creating at the vendor, in response to receiving the instrument request, a design plan that has been customized for the patient per data of the instrument request, the design plan including a plurality of instructions usable on a fabrication machine located at the healthcare facility to fabricate the customized patient-specific orthopaedic surgical instrument,

sending the design plan from the vendor to the healthcare facility,

loading the plurality of instructions onto a processor of the fabrication machine located at the healthcare facility, and

operating a the fabrication machine located at the healthcare facility to execute the plurality of instructions loaded on the fabrication machine to fabricate the customized patient-specific orthopaedic surgical instrument including a cutting slot sized to receive a cutting saw blade and a customized patient-specific negative contour shaped to receive a predetermined portion of the patient'"'"'s bone per data of the design plan.

2. The method of claim 1, wherein sending comprises transmitting the design plan to the healthcare facility via a network.

3. The method of claim 1, wherein sending comprises mailing the design plan to the healthcare facility.

4. The method of claim 1, wherein creating at the vendor includes generating the plurality of instructions based upon one or more medical images that depict at least one bone of the patient.

5. The method of claim 1, further comprising creating the design plan based upon one or more medical images that depict at least one bone of the patient.

6. The method of claim 1, wherein:

data of the instrument request comprises one or more medical images that depict at least one bone of the patient, and

receiving comprises receiving the instrument request that includes the one or more medical images.

7. The method of claim 1, wherein operating comprises operating the fabrication machine located at the healthcare facility to fabricate a customized patient-specific femoral cutting block per data of the design plan.

8. The method of claim 1, wherein operating comprises operating the fabrication machine located at the healthcare facility to fabricate a customized patient-specific tibial cutting block per data of the design plan.

9. A system for creating a customized patient-specific orthopaedic surgical instrument for a patient of a healthcare facility, comprising:

a client located at the healthcare facility, to generate an instrument request for a customized patient-specific orthopaedic surgical instrument that includes data and images relevant to the patient,

a design plan system to receive the instrument request and to generate a design plan that has been customized based upon the data of the instrument request, the design plan system being located at a vendor and being operable to generate a plurality of instructions usable on a fabrication machine located at the healthcare facility to fabricate the customized patient-specific orthopaedic surgical instrument, and

the fabrication machine located at the healthcare facility external to the vendor, the fabrication machine being operable to execute the plurality of instructions loaded on the fabrication machine to fabricate the customized patient-specific orthopaedic surgical instrument including a cutting slot sized to receive a cutting saw blade and a customized patient-specific negative contour shaped to receive a predetermined portion of the patient'"'"'s bone per data of the design plan generated by the design plan system.

10. The system of claim 9, wherein the design plan system generates the design plan based upon at least one image of the instrument request.

11. The system of claim 9, wherein the client is communicatively coupled to the design plan system via a network.

12. The system of claim 9, wherein the design plan system is communicatively coupled to the fabrication machine via a network.

13. The system of claim 9, wherein the fabrication machine is operable to fabricate a customized patient-specific femoral cutting block per data of the design plan generated by the design plan system.

14. The system of claim 9, wherein the fabrication machine is operable to fabricate a customized patient-specific tibial cutting block per data of the design plan generated by the design plan system.
