Method and system for managing inventories of orthopaedic implants
A computer assisted surgery system includes a controller configured to display images of the surgical procedure according to a workflow plan. The controller is configured to retrieve data and determine the workflow plan based on the data. The controller may also be configured to record and store data related to the surgical procedure on, for example, a hospital network.
1. A method of knee surgery, the method comprising:
generating a surgical workflow plan comprising an ordered selection of images and instructions corresponding to steps to be performed during the knee surgery,
inserting a ligament balance assessment device into a knee joint between a tibial bone and a femoral bone, wherein the ligament balance assessment device is configured to generate electronic signals in response to forces exerted on the ligament balance assessment device by at least one of the tibial bone and the femoral bone,
generating, using the electronic signals generated by the ligament balance assessment device, alignment data related to a balance of ligaments associated with the knee joint,
releasing the ligaments to achieve ligament balance in the knee joint when the alignment data indicates that the tibial and femoral bones are not aligned,
generating, in response to achieving the ligament balance in the knee joint, deviation data indicative of a deviation from the surgical workflow plan for the knee surgery, wherein the deviation data is accessible for use during the knee surgery, and
storing the deviation data.
2. The method of claim 1 , wherein the alignment data includes medial-lateral force data.
3. The method of claim 1 , wherein the alignment data includes femur and tibia axial alignment data.
4. The method of claim 1 , wherein the alignment data includes flexion and extension data.
5. The method of claim 1 , wherein the ligament balance assessment device is further configured to generate electronic signals in response to one or more distances measured between the tibial bone and the femoral bone.
6. A method of knee surgery comprising the steps of:
generating a surgical workflow plan comprising an ordered selection of images and instructions corresponding to steps to be performed during the knee surgery,
displaying the images and instructions during the knee surgery,
inserting a surgical instrument into a knee joint when instructed by the display of the images and instructions of the surgical workflow plan for the knee surgery,
generating, with the surgical instrument, electronic signals in response to force exerted on the surgical instrument by at least one bone of the knee joint,
generating, using the electronic signals generated by the surgical instrument, patient-related data while the surgical instrument is inserted in the knee joint,
displaying the patient-related data generated by the surgical instrument,
revising the surgical workflow plan for the knee surgery based on the patient-related data to include a custom set of images and instructions corresponding to steps to be performed during the knee surgery,
displaying the custom set of images and instructions during the knee surgery, and
performing the surgical steps included in the custom set of images and instructions during the knee surgery.
7. The method of claim 6 , wherein the patient-related data includes medial-lateral force data.
8. The method of claim 6 , wherein the patient-related data includes femur and tibia axial alignment data.
9. The method of claim 6 , wherein the patient-related data includes flexion and extension data.
10. The method of claim 6 , further comprising generating, with the surgical instrument, electronic signals in response to one or more distances measured between bones of the knee joint.
