Abstract
Example methods and systems may be used intraoperatively to help surgeons perform accurate and replicable surgeries, such as knee arthroplasty surgeries. An example system combines real time measurement and tracking components with functionality to compile data collected by the hardware to register a bone of a patient, calculate an axis (e.g., mechanical axis) of the leg of the patient, assist a surgeon in placing cut guides, and verify a placement of an inserted prosthesis.
Claims32
A system comprising:
- a measurement device to collect information of a surface of a bone of a limb of a patient, to track one or more reference points positioned on one or more bones or an anatomy of the patient, and to track one or more reference points positioned on a surgical device;
- one or more processors;
- and
- data storage including instructions executable by the one or more processors for performing functions comprising:
- receiving pre-operative imaging of at least a portion of the limb of the patient;
- aligning the pre-operative imaging with the collected information of the surface of the bone;
- determining a visual model of the bone based on the aligned pre-operative imaging with the collected information of the surface of the bone;
- recognizing a position and a movement of the bone in physical space based on the tracked reference points positioned on the one or more of the bone or the anatomy of the patient and causing the visual model of the bone to reflect the position and the movement of the bone in physical space;
- recognizing a position and a movement of the surgical device in physical space based on the tracked reference points positioned on the surgical device;
- and
- providing for display a virtual image overlaid onto the visual model of the bone, wherein the virtual image includes information for assisting in placement of the surgical device at a position on the bone based on the position and the movement of the surgical device in physical space.

A method comprising:
- receiving information, collected by a measurement device, of a surface of a bone of a limb of a patient;
- receiving pre-operative imaging of at least a portion of the limb of the patient;
- aligning the pre-operative imaging with the collected information of the surface of the bone;
- determining a visual model of the bone based on the aligned pre-operative imaging with the collected information of the surface of the bone;
- recognizing a position and a movement of the bone in physical space based on tracked reference points positioned on the one or more of the bone or the anatomy of the patient and causing the visual model of the bone to reflect the position and the movement of the bone in physical space;
- recognizing a position and a movement of a surgical device in physical space based on tracked reference points positioned on the surgical device;
- and
- providing for display a virtual image overlaid onto the visual model of the bone, wherein the virtual image includes information for assisting in placement of the surgical device at a position on the bone based on the position and the movement of the surgical device in physical space.

A non-transitory computer-readable medium having stored thereon instructions that when executed by a computing device that includes one or more processors causes the computing device to perform functions comprising:
- receiving information, collected by a measurement device, of a surface of a bone of a limb of a patient;
- receiving pre-operative imaging of at least a portion of the limb of the patient;
- aligning the pre-operative imaging with the collected information of the surface of the bone;
- determining a visual model of the bone based on the aligned pre-operative imaging with the collected information of the surface of the bone;
- recognizing a position and a movement of the bone in physical space based on tracked reference points positioned on the one or more of the bone or the anatomy of the patient and causing the visual model of the bone to reflect the position and the movement of the bone in physical space;
- recognizing a position and a movement of a surgical device in physical space based on tracked reference points positioned on the surgical device;
- and
- providing for display a virtual image overlaid onto the visual model of the bone, wherein the virtual image includes information for assisting in placement of the surgical device at a position on the bone based on the position and the movement of the surgical device in physical space.
