Abstract

Methods for performing orthopaedic surgical procedures using a handheld scanner are disclosed. The methods include, generally, performing one or more intra-operative scans using a handheld scanner, generating scan data from the intra-operatives scans, and comparing the scan data to a surgical plan. 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 method of performing an orthopaedic surgery on a patient, the method comprising:
positioning the patient on a surgical table in an operating room,
making an incision in the patient's tissue to expose a bone of the patient,
obtaining a first scan with a hand-held device, the first scan including a position and an orientation of the bone in the operating room,
transmitting the first scan from the hand-held device to a computing device,
operating the computing device to (i) compare the position and the orientation of the bone included in the first scan to a surgical plan including a planned position and a planned orientation of the patient's bone and (ii) generate an adjusted planned position and an adjusted planned orientation of an orthopaedic prosthetic component in the patient's bone based on the position and the orientation of the bone included in the first scan,
implanting the orthopaedic prosthetic component in the bone of the patient,
obtaining a second scan with the hand-held device, the second scan including a position and an orientation of the orthopaedic prosthetic component in the bone,
transmitting the second scan from the hand-held device to the computing device, and
operating the computing device to confirm that the position and the orientation of the orthopaedic prosthetic component included in the second scan matches the adjusted planned position and the adjusted planned orientation of the orthopaedic prosthetic component.

2. The method of claim 1 , wherein obtaining the first scan further comprises positioning an optical detector of the hand-held device inside of the incision formed in the patient's tissue, and performing the first scan with the hand-held device.

3. The method of claim 1 , wherein obtaining the first scan with the hand-held device further comprises obtaining the first scan with an optical detector positioned on the hand-held device, the optical detector being configured to detect electromagnetic radiation reflected from a surface of interest on the patient.

4. The method of claim 3 , wherein the hand-held device is a white light scanner configured to determine one or more locations of a surface of interest on the patient by detecting one or more characteristics of white light reflected from the surface of interest.

5. The method of claim 3 , wherein the hand-held device is a laser scanner that includes one or more optical detectors configured to determine one or more locations on a surface of interest on the patient by detecting one or more characteristics of laser light reflected from the surface of interest.

6. The method of claim 1 , wherein when obtaining a scan of the patient the patient is not moved to a new location and the position of the patient relative to a reference plane is not modified.

7. The method of claim 1 , wherein operating the computing device further comprises operating the computing device to display a comparison of the position and the orientation of the bone included in the first scan to the surgical plan that includes the planned position and the planned orientation of the patient's bone.

8. The method of claim 1 , wherein operating the computing device further comprises operating the computing device to display a comparison of the position and orientation of the orthopaedic prosthetic component included in the second scan to the surgical plan that includes the planned component position and planned component orientation of the orthopaedic prosthetic component in the patient's bone.

9. The method of claim 1 , further comprising:
positioning an orthopaedic trialing component in the bone of the patient,
obtaining a third scan with the hand-held device, the third scan including a first position and a first orientation of the orthopaedic trialing component,
transmitting the third scan from the hand-held device to the computing device, and
operating the computing device to determine trialing feedback data by comparing the first position and the first orientation of the orthopaedic trialing component included in the third scan to the surgical plan that includes a planned component position and a planned component orientation of the orthopaedic prosthetic component.

10. The method of claim 9 , further comprising:
adjusting the orthopaedic trialing component to be in a second position and a second orientation in the bone of the patient based on the trialing feedback data,
obtaining a fourth scan with the hand-held device, the fourth scan including data related to the second position and the second orientation of the orthopaedic trialing component, and
operating the computing device to determine additional trialing feedback data by comparing the second position and the second orientation of the orthopaedic trialing component included in the fourth scan to the surgical plan.

11. The method of claim 9 , further comprising:
selecting a different orthopaedic trialing component based on the trialing feedback data,
positioning the different orthopaedic trialing component in the bone of the patient,
obtaining a fifth scan with the hand-held device, the fifth scan including a position and an orientation of the different orthopaedic trialing component,
transmitting the fifth scan from the hand-held device to the computing device, and
operating the computing device to compare the position and orientation of the different orthopaedic trialing component included in the fifth scan to the surgical plan.

12. A method of performing an orthopaedic surgery on a patient, the method comprising:
positioning the patient on a surgical table in an operating room,
making an incision in the patient's tissue to expose a bone of the patient,
obtaining a first scan with a hand-held device, the first scan including a position and an orientation of the bone in the operating room,
transmitting the first scan from the hand-held device to a computing device,
operating the computing device to (i) compare the position and the orientation of the bone included in the first scan to a surgical plan including a planned position and a planned orientation of the patient's bone and (ii) generate an adjusted planned position and an adjusted planned orientation of an orthopaedic prosthetic component in the patient's bone based on the position and the orientation of the bone included in the first scan,
positioning an orthopaedic trialing component in the bone of the patient based on the adjusted planned position and the adjusted planned orientation,
obtaining a second scan with the hand-held device, the second scan including a first position and a first orientation of the orthopaedic trialing component,
transmitting the second scan from the hand-held device to the computing device, and
operating the computing device to determine trialing feedback data by comparing the first position and the first orientation of the orthopaedic trialing component included in the second scan to the surgical plan that includes a planned component position and a planned component orientation of the orthopaedic prosthetic component.

13. The method of claim 12 , further comprising:
adjusting the orthopaedic trialing component to be in a second position and a second orientation in the bone of the patient based on the trialing feedback data,
obtaining a third scan with the hand-held device, the third scan including data related to the second position and the second orientation of the orthopaedic trialing component,
transmitting the third scan from the hand-held device to the computing device, and
operating the computing device to compare the second position and the second orientation of the orthopaedic trial
