Abstract

A method for assessing suture line integrity includes loading a navigation plan into a navigation system, the navigation plan including a planned pathway shown in a 3D model, inserting a probe into a patient'"'"'s airways, the probe including a location sensor in operative communication with the navigation system, registering a sensed location of the probe with the planned pathway, and selecting a target in the navigation plan, the target including a proposed suture line. The method further includes presenting a view of the 3D model showing the planned pathway and indicating the sensed location of the probe, navigating the probe through the airways of the patient'"'"'s lungs toward the target, and imaging the proposed suture line of the target, via the probe, to determine tissue integrity surrounding the proposed suture line.

Claims

1. A method for assessing suture line integrity, the method comprising:

receiving a navigation plan into a navigation computer, the navigation plan including a planned pathway shown in a 3D model;

registering a sensed location of a probe within a patient'"'"'s airways with the planned pathway, the probe including a location sensor in communication with the navigation computer;

displaying a line to be sutured over a target identified in the navigation plan;

presenting a view of the 3D model showing the planned pathway and indicating the sensed location of the probe;

receiving image data of tissue surrounding the line to be sutured from the probe within the patient'"'"'s airways; and

determining integrity of the tissue surrounding the line to be sutured based on the received image data.

2. The method according to claim 1, further comprising generating the 3D model from pre-procedure image data.

3. The method according to claim 1, further comprising assessing health of the tissue surrounding the line to be sutured.

4. The method according to claim 1, further comprising displaying one or more images of the line to be sutured on a display.

5. The method according to claim 4, further comprising imaging an actual suture line.

6. A medical image display system, comprising:

a network interface configured to receive positional information of a probe from a position sensor of the probe and image data from a navigation plan including a planned pathway of a lung;

a memory storing the positional information, the image data, and instructions;

a processor configured to execute the instructions; and

a display configured to simultaneously display the positional information and image data;

wherein the instructions, when executed by the processor, cause the medical image display system to;

display a line to be sutured over a target identified in the navigation plan;

image tissue surrounding the line to be sutured by allowing the probe to scan the tissue surrounding the line to be sutured and integrity of the tissue surrounding the line to be sutured based on the imaged tissue.

7. The system according to claim 6, wherein the image data is acquired by one or more imaging modalities.

8. The system according to claim 7, wherein the imaging modalities are selected from the group comprising a CT scan, an X-ray scan, a computerized axial tomography (CAT) scan, a magnetic resonance imaging (MRI) scan, ultrasonography, contrast imaging, fluoroscopy, nuclear scans, and positron emission tomography (PET).

9. The system according to claim 6, wherein the image data are selected from the group consisting of sagittal, coronal, and axial images.

10. The system according to claim 6, wherein one or more images of the tissue surrounding the line to be sutured and the image data are controlled by a control function.

11. The system according to claim 10, wherein the control function includes at least zooming and panning.

12. The system according to claim 6, wherein the planned pathway is shown in a 3D model.

13. The system according to claim 6, wherein the positional information and image data are dynamically displayed on the display.

14. The system according to claim 6, wherein allowing the probe to scan the tissue surrounding the line to be sutured provides for predictive data used to determine the integrity of the tissue surrounding the line to be sutured.

15. A medical image display system, comprising:

a memory storing instructions, positional information of a probe navigated within a patient, and a navigation plan including a planned pathway through a patient'"'"'s airways;

a processor configured to execute the instructions; and

a display configured to display the planned pathway and the positional information of the probe;

wherein the instructions, when executed by the processor, cause the medical image display system to;

display a line to be sutured over a target identified in the navigation plan;

receive image data of tissue surrounding the line to be sutured from the probe; and

determine integrity of the tissue surrounding the line to be sutured based on the image data received from the probe.
