Abstract

Systems and methods for planning and assisting orthopaedic surgical procedures include a computing device and a robotic surgical device. The computing device defines a surgical coordinate system relative to a bone of a patient and captures a plurality of point positions in the surgical coordinate system. The plurality of point positions includes a first point position representing a location on a soft tissue surface covering a portion of the patient's bone. The computing device identifies an estimated soft tissue thickness value for each of the plurality of point positions and registers a three-dimensional model of the patient's bone in the surgical coordinate system based on the plurality of point positions and the estimated soft tissue thickness values. The computer system may control the robotic surgical device according to the registered bone model.

Claims (41)

1. A bone model registration method comprising:

defining, by a computing device, a surgical coordinate system relative to a bone of a patient;

capturing, by the computing device, a plurality of point positions in the surgical coordinate system, wherein each of the plurality of point positions is associated with an anatomical landmark of the patient's bone, and wherein the plurality of point positions comprises a first point position representing a location on a soft tissue surface covering a portion of the patient's bone;

identifying, by the computing device, for each of the plurality of point positions, an estimated soft tissue thickness value; and

registering, by the computing device, a three-dimensional model of the patient's bone in the surgical coordinate system based on the plurality of point positions and the estimated soft tissue thickness values, wherein registering the three-dimensional model comprises determining, for each of the plurality of point positions, a distance between that point position and a corresponding point from the three-dimensional model extended by the estimated soft tissue thickness value associated with that point position, to determine a set of distances associated with a transformation of the three-dimensional model.

2. The method of claim 1 , wherein capturing the plurality of point positions comprises tracking a location of a registration tool having a pointer using a camera array coupled to the computing device, wherein the pointer of the registration tool directly contacts the soft tissue surface but does not directly contact the patient's bone while the first point position is captured.

3. The method of claim 2 , wherein the plurality of point positions further comprises a second point position captured while the pointer of the registration tool directly contacts the patient's bone.

4. The method of claim 3 , wherein identifying an estimated soft tissue thickness value for each of the plurality of point positions comprises:

identifying the estimated soft tissue thickness value for the first point position as a number greater than zero; and

identifying the estimated soft tissue thickness value for the second point position as zero.

5. The method of claim 2 , wherein capturing the plurality of point positions comprises moving the pointer of the registration tool along a surface of the patient's bone or along the soft tissue surface to capture a point cloud associated with an anatomical landmark.

6. The method of claim 1 , wherein identifying an estimated soft tissue thickness value for each of the plurality of point positions comprises receiving one or more estimates of soft tissue thickness from a surgeon during an orthopaedic surgical procedure.

7. The method of claim 1 , wherein identifying an estimated soft tissue thickness value for each of the plurality of point positions comprises retrieving, from a memory device, one or more initial estimated soft tissue thickness values associated with the plurality of point positions.

8. The method of claim 1 , further comprising:

receiving, by the computing device, an updated estimated soft tissue thickness value for at least one of the plurality of point positions; and

re-registering, by the computing device, the three-dimensional model of the patient's bone in the surgical coordinate system based on the plurality of point positions and the estimated soft tissue thickness values, including the at least one updated estimated soft tissue thickness value.

9. The method of claim 1 , wherein registering the three-dimensional model further comprises optimizing the set of distances by iteratively adjusting the transformation of the three-dimensional model to improve registration quality of the three-dimensional model.

10. The method of claim 9 , wherein registering the three-dimensional model further comprises optimizing the set of distances by iteratively adjusting the estimated soft tissue thickness values associated with one or more of the plurality of point positions to improve registration quality of the three-dimensional model.

11. The method of claim 1 , further comprising displaying, by the computing device, after registering the three-dimensional model, a representation of the three-dimensional model in the surgical coordinate system.

12. The method of claim 11 , further comprising displaying, by the computing device, the plurality of point positions relative to the displayed representation of the three-dimensional model.

13. The method of claim 12 , wherein displaying the plurality of point positions relative to the displayed representation of the three-dimensional model comprises color-coding each of the plurality of point positions as a function of a distance between each point position and a corresponding point from the three-dimensional model extended by the estimated soft tissue thickness value associated with that point position.

14. The method of claim 11 , further comprising, after registering the three-dimensional model:

capturing, by the computing device, a confirmation point position while a pointer of a registration tool contacts the soft tissue surface covering the portion of the patient's bone;

displaying, by the computing device, the confirmation point position relative to the displayed representation of the three-dimensional model; and

displaying, by the computing device, a difference between the confirmation point position and a corresponding point from the three-dimensional model extended by the estimated soft tissue thickness value associated with the corresponding point.

15. The method of claim 14 , wherein displaying the difference between the confirmation point position and the corresponding point from the three-dimensional model extended by the estimated soft tissue thickness value associated with the corresponding point comprises:

displaying the confirmation point position using a first color if the difference is less than a first threshold; and

displaying the confirmation point position using a second color if the difference is greater than the first threshold, the second color being different from the first color.

16. The method of claim 1 , further comprising creating, by the computing device, the three-dimensional model based on one or more preoperative medical images.

17. The method of claim 1 , further comprising controlling, by the computing device, a robotic surgical device in the surgical coordinate system based on the three-dimensional model after registering the three-dimensional model.

18. An orthopaedic surgical system comprising:

a computing device configured to:

define a surgical coordinate system relative to a bone of the patient;

capture a plurality of point positions in the surgical coordinate system, wherein each of the plurality of point positions is associated with an anatomical landmark of the patient's bone, and wherein the plurality of point positions comprises a first point position representing a location on a soft tissue surface covering a portion of the patient's bone;

identify, for each of the plurality of point positions, an estimated soft tissue thickness value; and

register a three-dimensional model of the patient's bone in the surgical coordinate system based on the plurality of point positions and the estimated soft tissue thickness values at least in part by determining, for each of the plurality of point positions, a distance between that point position and a corresponding point from the three-dimensional model extended by the estimated soft tissue thickness value associated with that point position, to determine a set of distances associated with a transformation of the three-dimensional model.

19. The system of claim 18 , further comprising:

a registration tool having a pointer configured to be contacted with various locations on a patient's anatomy; and

a camera array coupled to the computing device;

wherein the computing device is configured to capture the plurality of point positions by tracking a location of the registration tool using the camera array, and wherein the computing device is configured to capture the first point position while the pointer of the registration tool directly contacts the soft tissue surface but does not directly contact the patient's bone.

20. The system of claim 18 , further comprising a robotic surgical device configured to assist with resection of the patient's bone, wherein the computing device is further configured to control the robotic surgical device in the surgical coordinate system based on the three-dimensional model after registering the three-dimensional model.
