Abstract
Aspects of the present disclosure include surgical systems that provide a cost-effective, accurate, and efficient system for performing surgical procedures. In one aspect of the disclosure, a surgical system utilizes an intra-operative 3D scanner that can be used to determine anatomical landmarks and calculate surgical positions based on such anatomical landmarks. In some examples, aspects of the present disclosure also include providing guidance information for guiding the placement of a surgical instrument according to the calculated surgical positions.
Claims20
A system for orthopedic surgery without using optical trackers, the system comprising:
- an intra-operative 3D scanner;
- and
- a processor that is connected to the intra-operative 3D scanner and that is configured to perform functions comprising:
- receiving, from the intra-operative 3D scanner, scan data from an intra-operative scan of a bone surface in a region of anatomical interest;
- generating, from the scan data, a 3D image;
- identifying, in the 3D image, one or more anatomical landmark on the bone surface;
- calculating, according to the one or more anatomical landmark that was identified, a surgical position;
- generating guidance information, according to the surgical position, for guiding a surgical procedure;
- and
- guiding a surgical tool, based on the generated guidance information, to perform an act including at least one of:
- (a) cutting bone and (b) suture placement;
- the system further comprising a projector that is connected to the processor and that projects light to form a target in the region of anatomical interest, wherein the target is in a position and an orientation relative to the region of anatomical interest that were determined according to the surgical position that was calculated;
- wherein the intra-operative 3D scanner is configured to perform surface height measurements of the bone surface;
- wherein the surface height measurements are included in the scan data;
- and
- wherein the projector is a hologram projector and wherein the light that is projected forms a hologram of the target.
