Abstract
A method of preoperative planning comprises creating a virtual model of a native patient tissue; placing a virtual device into a desired device orientation relative to the virtual model of the native patient tissue; specifying at least one structural change to the native patient tissue to facilitate placement of the virtual device in the desired device orientation; creating a virtual model of an altered patient tissue responsive to the specifying at least one structural change to the native patient tissue; and fabricating a tangible representation of a bone using the virtual model of the altered patient tissue.
Claims20
A method for preoperatively planning the provision of a prosthetic implant device in a surgical procedure, the method comprising:
- creating a virtual model of a native patient tissue;
- receiving from a user a selection of a prosthetic implant device from a library of components;
- placing a virtual representation of said prosthetic implant device into a device orientation relative to the virtual model of the native patient tissue;
- determining at least one landmark orientation for placement of at least one virtual landmark relative to the native patient tissue and to the device orientation, the at least one virtual landmark being representative of a non-tissue landmark;
- generating a virtual patient-specific target trajectory for a robotic surgical aid relative to said virtual model of the native patient tissue for placement of the non-tissue landmark in said landmark orientation relative to the native patient tissue;
- and
- identifying a stock instrument from a library of components for interacting with the non-tissue landmark sequentially after use of the robotic surgical aid to install the non-tissue landmark.
A system for preoperatively planning the provision of a prosthetic implant device in a surgical procedure, comprising:
- a processing unit;
- and
- a non-transitory computer-readable memory communicatively coupled to the processing unit and comprising computer-readable program instructions executable by the processing unit for:
- creating a virtual model of a native patient tissue;
- receiving from a user a selection of a prosthetic implant device from a library of components;
- placing a virtual representation of said prosthetic implant device into a device orientation relative to the virtual model of the native patient tissue;
- determining at least one landmark orientation for placement of at least one virtual landmark relative to the native patient tissue and to the device orientation, the at least one virtual landmark being representative of a non-tissue landmark;
- generating a virtual patient-specific target trajectory for a robotic surgical aid relative to said virtual model of the native patient tissue for placement of the non-tissue landmark in said landmark orientation relative to the native patient tissue;
- and
- identifying a stock instrument from a library of components for interacting with the non-tissue landmark sequentially after use of the robotic surgical aid to install the non-tissue landmark.
