SYSTEM OF PREOPERATIVE PLANNING AND PROVISION OF PATIENT-SPECIFIC SURGICAL AIDS
First Claim
1. A method of preoperative planning and provision of patient-specific surgical aids, the method comprising the steps of:
- creating a virtual model of a native patient tissue;
placing a virtual device into a predetermined device orientation relative to the virtual model of the native patient tissue;
specifying at least one predetermined landmark orientation for placement of at least one virtual landmark relative to the native patient tissue;
generating a virtual patient-specific template containing the predetermined landmark orientation and having a landmark guiding feature;
generating at least one virtual patient-specific placement guide configured to interact simultaneously with at least one previously placed virtual landmark and the virtual device when the virtual device is in the predetermined device orientation;
creating a physical patient-specific template as a tangible representation of the virtual patient-specific template; and
creating a physical patient-specific placement guide as a tangible representation of the virtual patient-specific placement guide.

Abstract
A method of preoperative planning and provision of patient-specific surgical aids includes creating a virtual model of a native patient tissue. A virtual device is placed into a predetermined device orientation relative to the virtual model of the native patient tissue. At least one predetermined landmark orientation is specified for placement of at least one virtual landmark relative to the native patient tissue. A virtual patient-specific template containing the predetermined landmark orientation and having a landmark guiding feature is generated. At least one virtual patient-specific placement guide configured to interact simultaneously with at least one previously placed virtual landmark and the virtual device when the virtual device is in the predetermined device orientation is generated. A physical patient-specific template is created as a tangible representation of the virtual patient-specific template. A physical patient-specific placement guide is created as a tangible representation of the virtual patient-specific placement guide.

10. A method of preoperative planning and provision of patient-specific surgical aids, the method comprising the steps of:
-
choosing a device for placement in engagement with a native patient tissue; virtually specifying a predetermined device orientation for the device with respect to the native patient tissue; virtually placing at least one landmark in a predetermined landmark orientation with respect to the predetermined device orientation; virtually modeling a patient-specific placement guide, the patient-specific placement guide being simultaneously mated with the device and registered with at least one landmark when the device is in the predetermined device orientation; virtually modeling a patient-specific template, the patient-specific template being configured to mate with the native patient tissue, the patient-specific template having a landmark guiding feature configured to place the landmark in the predetermined landmark orientation when the patient-specific template is mated with the native patient tissue; creating a physical version of the patient-specific placement guide; and creating a physical version of the patient-specific template. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)

20. A computer readable medium having computer executable instructions for performing the method comprising:
-
receiving scanned image data based on an imaging scan of a native patient tissue; displaying an image of the native patient tissue based on the received scanned image data; displaying placement of an image of a selected device over the image of the native patient tissue; reorienting the image of the selected device over the image of the native patient tissue into a predetermined device orientation; displaying placement of an image of at least one selected landmark in a predetermined landmark orientation over the image of the native patient tissue; displaying placement of an image of a selected guide blank in a predetermined guide orientation over the image of the native patient tissue and the image of the selected device, when the image of the selected device is in the predetermined device orientation; providing the selected guide blank with at least one orienting feature, the provided orienting feature being registered with at least one selected landmark when the image of a selected guide blank is in the predetermined guide orientation and the image of the selected device is in the predetermined device orientation; and fabricating a physical guide from the selected guide blank having the provided orienting feature. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29)
