Abstract

Methods for performing orthopaedic surgical procedures including generating scan data from the intra-operatives scans and comparing the scan data to a surgical plan are disclosed. The scan data and other feedback data are used to validate the position and orientation of orthopaedic prosthetic component implanted in a body of the patient.

First claim

The invention claimed is:

1. A surgical feedback system comprising:
a hand-held device configured to obtain a second scan of a patient's bone, the second scan including a position and an orientation of an orthopaedic prosthetic component implanted in the patient's bone, and
a computing device communicatively coupled to the hand-held device, the computing device configured to:
receive data from a first scan of the patient's bone,
compare a position and an orientation of the patient's bone included in the data from the first scan to a planned position and a planned orientation of the patient's bone in a surgical plan,
generate an adjusted planned position and an adjusted planned orientation of the orthopaedic prosthetic component relative to the patient's bone based on the comparison of the position and the orientation of the patient's bone included in the data from the first scan to the planned position and the planned orientation of the patient's bone in the surgical plan,
receive data from the second scan of the patient's bone by the hand-held device, and
confirm that the position and the orientation of the orthopaedic prosthetic component included in the data from the second scan matches the adjusted planned position and the adjusted planned orientation of the orthopaedic prosthetic component.

2. The surgical feedback system of claim 1 , wherein the hand-held device comprises an optical detector configured to detect electromagnetic radiation reflected from a surface of interest on the patient.

3. The surgical feedback system of claim 2 , wherein the optical detector is configured to be positioned inside of an incision formed in the patient's tissue.

4. The surgical feedback system of claim 2 , wherein the hand-held device is a white light scanner configured to determine one or more locations of the surface of interest on the patient by detecting one or more characteristics of white light reflected from the surface of interest.

5. The surgical feedback system of claim 2 , wherein the hand-held device is a laser scanner configured to determine one or more locations on the surface of interest on the patient by detecting one or more characteristics of laser light reflected from the surface of interest.

6. The surgical feedback system of claim 1 , wherein the computing device is communicatively coupled to the hand-held device via a network.

7. The surgical feedback system of claim 1 , wherein the computing device is further configured to display a comparison of the position and the orientation of the patient's bone included in the data from the first scan to the planned position and the planned orientation of the patient's bone in the surgical plan.

8. The surgical feedback system of claim 1 , wherein the computing device is further configured to display a comparison of the position and orientation of the orthopaedic prosthetic component included in the data from the second scan to a planned component position and a planned component orientation of the orthopaedic prosthetic component in the surgical plan.

9. The surgical feedback system of claim 1 , wherein:
the hand-held device is further configured to obtain a third scan of an orthopaedic trialing component in the patient's bone, the third scan including a first position and a first orientation of the orthopaedic trialing component, and
the computing device is further configured to determine trialing feedback data by comparing the first position and the first orientation of the orthopaedic trialing component included in data from the third scan to a planned component position and a planned component orientation of the orthopaedic prosthetic component in the surgical plan.

10. The surgical feedback system of claim 9 , wherein:
the hand-held device is further configured to obtain a fourth scan of the orthopaedic trialing component in the patient's bone, the fourth scan including a second position and a second orientation of the orthopaedic trialing component, and
the computing device is further configured to determine additional trialing feedback data by comparing the second position and the second orientation of the orthopaedic trialing component included in data from the fourth scan to the planned component position and the planned component orientation of the orthopaedic prosthetic component in the surgical plan.

11. The surgical feedback system of claim 9 , wherein:
the hand-held device is further configured to obtain a fourth scan of a different orthopaedic trialing component in the patient's bone, the fourth scan including a second position and a second orientation of the different orthopaedic trialing component, and
the computing device is further configured to determine additional trialing feedback data by comparing the second position and the second orientation of the different orthopaedic trialing component included in data from the fourth scan to the planned component position and the planned component orientation of the orthopaedic prosthetic component in the surgical plan.

12. A surgical feedback system comprising:
a hand-held device configured to obtain a second scan of a patient's bone, the second scan including a first position and a first orientation of an orthopaedic trialing component positioned in the patient's bone, and
a computing device communicatively coupled to the hand-held device, the computing device configured to:
receive data from a first scan of the patient's bone,
compare a position and an orientation of the patient's bone included in the data from the first scan to a planned position and a planned orientation of the patient's bone in a surgical plan,
generate an adjusted planned position and an adjusted planned orientation of an orthopaedic prosthetic component relative to the patient's bone based on the comparison of the position and the orientation of the patient's bone included in the data from the first scan to the planned position and the planned orientation of the patient's bone in the surgical plan,
receive data from the second scan of the patient's bone by the hand-held device, and
determine trialing feedback data by comparing the first position and the first orientation of the orthopaedic trialing component included in the data from the second scan to the adjusted planned position and the adjusted planned orientation of the orthopaedic prosthetic component relative to the patient's bone.

13. The surgical feedback system of claim 12 , wherein:
the hand-held device is further configured to obtain a third scan of the orthopaedic trialing component in the patient's bone, the third scan including a second position and a second orientation of the orthopaedic trialing component, and
the computing device is further configured to determine additional trialing feedback data by comparing the second position and the second orientation of the orthopaedic trialing component included in data from the third scan to the adjusted planned position and the adjusted planned orientation of the orthopaedic prosthetic component relative to the patient's bone.

14. The surgical feedback system of claim 12 , wherein:
the hand-held device is further configured to obtain a third scan of a different orthopaedic trialing component in the patient's bone, the third scan including a second position and a second orientation of the different orthopaedic trialing component, and
the computing device is further configured to determine additional trialing feedback data by comparing the second position and the second orientation of the different orthopaedic trialing component included in data from the third scan to the adjusted planned position and the adjusted pla
