Abstract

A system for surgical mesh analysis includes a display screen, a processor, and a memory. The memory has instructions stored thereon, which when executed by the processor, cause the system to: access an image of a surgical site ( 602 ). The image includes the surgical mesh. The surgical mesh includes a grid of cells. The instructions, when executed by the processor further cause the system to detect a first desired location on the surgical mesh in the image ( 604 ); detect a second desired location on the surgical mesh in the image ( 606 ); determine a distance between the first desired location and the second desired location along the surgical mesh in the image ( 608 ); and display, on the display screen, the determined distance ( 610 ).

Claims (41)

1 . A system for surgical mesh analysis, the system comprising:

a display screen;

a processor; and

a memory having instructions stored thereon, which when executed by the processor, cause the system to:

access an image of a surgical site, the image including the surgical mesh, wherein the surgical mesh includes a grid of cells;

detect a first location on the surgical mesh in the image;

detect a second location on the surgical mesh in the image;

determine a distance between the first location and the second location along the surgical mesh in the image;

display, on the display screen, the determined distance, and

wherein when executing the instructions to determine the distance between the first location and the second location, the instructions further cause the system to at least one of:

determine a number of cells of the grid of cells along a shortest distance between the first location and the second location;

perform a Euclidean reconstruction based on analyzing the surgical mesh as a 3D structure composed of polygons, each polygon corresponding to a unique cell of the grid of cells; or

perform a geodesic reconstruction based on analyzing the surgical mesh by forming a topographic map of the surgical mesh and calculating distances between the first desired location and the second desired location based thereon.

2 . The system according to claim 1 , wherein the image is obtained by an imaging device directed at the surgical mesh.

3 . The system according to claim 1 , wherein the accessed image includes at least one of a 2D image or a 3D image.

4 . The system according to claim 1 , wherein the instructions, when executed by the processor, further cause the system to identify an item located on the surgical mesh.

5 . The system according to claim 4 , wherein the item includes a tack, wherein the tack is configured for attaching the surgical mesh to a tissue.

6 . The system according to claim 5 , wherein the instructions, when executed by the processor, further cause the system to identify, based on the image, whether the surgical mesh is attached to the tissue by a tack located at a location along the surgical mesh.

7 . The system according to claim 1 , wherein the surgical site is at least one of a hernia surgical site or a laparoscopy surgical site.

8 . The system according to claim 1 , wherein the instructions, when executed by the processor, further cause the system to display on the display screen a pre-selected placement of tacks on the surgical mesh.

9 . The system according to claim 1 , wherein the instructions, when executed by the processor, further cause the system to:

determine at least one placement location for at least one tack; and

display the determined at least one placement location on the display screen.

10 . A computer-implemented method for surgical mesh analysis, the method comprising:

accessing an image of a surgical site, the image including the surgical mesh, wherein the surgical mesh includes a grid of cells;

detecting a first location on the surgical mesh in the image;

detecting a second location on the surgical mesh in the image;

determining a distance between the first location and the second location along the surgical mesh in the image, wherein determining the distance between the first location and the second location further comprises at least one of:

determining a number of cells of the grid of cells along a shortest distance between the first location and the second location;

performing a Euclidean reconstruction based on analyzing the surgical mesh as a 3D structure composed of polygons, each polygon corresponding to a unique cell of the grid of cells; or

performing a geodesic reconstruction based on analyzing the surgical mesh by forming a topographic map of the surgical mesh and calculating a distances between the first location and the second location based thereon; and

displaying, on the display, the determined distance.

11 . The computer-implemented method according to claim 10 , further comprising using an imaging device directed at the surgical mesh to obtain the image.

12 . The computer-implemented method according to claim 10 , wherein the accessing of the image includes accessing at least one of a 2D image or a 3D image.

13 . The computer-implemented method according to claim 10 , further comprising identifying an item located on the surgical mesh.

14 . The computer-implemented method according to claim 13 , wherein the identifying of the item includes identifying a tack which is configured for attaching the surgical mesh to a tissue.

15 . The computer-implemented method according to claim 14 , further comprising identifying, based on the image, when the surgical mesh is attached to the tissue by a tack located at a location along the surgical mesh.

16 . The computer-implemented method according to claim 10 , further comprising determining a pre-selected placement of tacks on the surgical mesh.

17 . The computer-implemented method according to claim 10 , further comprising:

determining placement locations for one or more tacks; and

displaying the determined placement locations.
