Method and apparatus for manufacturing an implant
View Patent ↗An orthopedic implant manufacturing method. The method includes preparing a pre-operative surgical plan for a specific patient, the surgical plan including a three-dimensional image of a patient's joint indicating at least one resection plane, communicating the surgical plan to a surgeon of the patient, and receiving approval of the surgical plan and the resection plane by the surgeon. The method also includes providing automated osteophyte/protrusion removal control for surgeon manipulation, receiving a modified three-dimensional image of a patient's joint indicating an osteophyte/protrusion removal and a recommendation for a corresponding selected orthopedic implant from the surgeon, and requesting manufacture of the selected orthopedic implant.
1. A method for manufacturing an implant for a specific patient, comprising:
accessing a data file including a pre-operative plan of the patient with a handheld device, the pre-operative plan including a three-dimensional image of the patient's un-resected distal femoral bone reconstructed from two-dimensional medical imaging scans of the patient's knee joint and including a planned resection plane corresponding to a planned femoral knee implant location for the femoral bone of the patient;
viewing on the display of the handheld device the three-dimensional image of the patient's distal femoral bone with the planned resection plane;
modifying the image of the femoral bone on the display of the handheld device by removing from the image of the distal femoral bone a portion of a bone protrusion associated with an edge of the planned resection plane by providing inputs to the handheld device;
moving on the image of the distal femoral bone a visual slider associated with the edge of the planned resection plane to control removal of the image of the protrusion by providing inputs to the handheld device;
selecting on the display a femoral knee implant corresponding to the modified image of the femoral bone;
saving an edited pre-operative plan associated with the provided inputs to the handheld device and the modified image of the femoral bone;
transmitting the edited pre-operative plan to an implant manufacturer; and
requesting manufacture of the femoral knee implant according to the edited preoperative plan and the modified image of the distal femoral bone.
2. The method of claim 1 , further comprising:
generating the pre-operative plan at a service provider; and
transmitting the edited pre-operative plan to the service provider.
3. The method of claim 1 , further comprising:
receiving the femoral knee implant; and
forwarding the femoral knee implant for implantation.
4. The method of claim 3 , wherein generating the pre-operative plan includes at least one of determining a substantially anatomical orientation of the patient and selecting resections and implants to achieve the determined substantially anatomical orientation after performing the operative procedure based on the pre-operative plan.
5. The method of claim 1 , further comprising:
acquiring image data of the patient;
determining a healthy anatomical orientation of the patient; and
selecting the resection plane and associated implants to achieve the determined substantially anatomical orientation after performing the operative procedure based on the pre-operative plan.
6. The method of claim 1 , wherein accessing a data file includes copying the data file to the handheld device and executing a program to process the data file for viewing with the handheld device.
7. The method of claim 6 wherein editing the pre-operative plan includes:
executing a program with the handheld device based on the provided inputs.
8. The method of claim 1 , wherein accessing a data file includes:
communicating with a main processor to transmit information regarding an image to the handheld device; and
viewing the image on the handheld device.
9. The method of claim 8 , wherein editing the pre-operative plan includes:
transmitting the provided inputs with the handheld device to the main processor; and
executing a program only with the main processor to change the pre-operative plan to the edited pre-operative plan;
wherein saving an edited pre-operative plan includes saving the edited pre-operative plan at a location separate from the handheld device.
10. The method of claim 1 , wherein accessing the pre-operative plan includes:
downloading the pre-operative plan to a handheld device.
11. The method of claim 10 , wherein downloading the pre-operative file includes transmitting the data file wirelessly via a cellular or mobile phone data network.
12. The method of claim 10 , wherein downloading includes transmitting wirelessly to the handheld device via a local access wireless transmission data protocol.
13. The method of claim 10 , wherein downloading includes transmitting to the handheld device via a cable connection or physical connection to a main processor and main storage system.
14. The method of claim 10 , wherein viewing the pre-operative plan includes viewing a cropped portion of an image of the pre-operative plan.
15. The method of claim 14 , further comprising:
zooming into the cropped portion of the image of the pre-operative plan to view in detail a portion of the cropped portion of the pre-operative plan.
16. The method of claim 15 , further comprising editing only the cropped portion of the image of the pre-operative plan.
17. The method of claim 16 , wherein saving the edited pre-operative plan includes saving the edited pre-operative plan in a storage system of the handheld device.
18. The method of claim 10 , further comprising executing a program on the handheld device to edit the pre-operative plan on the handheld device.
19. The method of claim 1 , wherein accessing the pre-operative plan includes wirelessly accessing the pre-operative plan with a selected wireless communication system and protocol.
20. The method of claim 19 , wherein the selected wireless data system and protocol includes a cellular or mobile wireless data system.
21. The method of claim 19 , further comprising:
transmitting to the main processor via the wireless transmission system, the provided inputs from the handheld device;
wherein editing the pre-operative plan includes executing a program with the main processor to edit the pre-operative plan to generate the edited pre-operative plan.
22. The method of claim 21 , wherein saving the edited pre-operative plan includes saving the edited pre-operative plan at the main storage system associated with the main processor separate from the handheld device.
23. The method of claim 21 , further comprising: changing at least one parameter of the pre-operative plan data file based on the provided inputs.
24. The method of claim 1 , further comprising:
displaying a plurality of depth contours associated with the bone protrusion on the display;
selecting one of the depth contours by the surgeon using the bone removal tool on the display; and
displaying the image of the bone with the bone protrusion removed to the selected depth contour on the display.
25. The method of claim 24 , wherein the protrusion is an osteophyte of the bone.
