Abstract

Certain embodiments may relate to apparatuses and methods for performing surgical procedures. For example, a method may comprise initiating detection and tracking of at least one surgical instrument (including associated surgical material) within a surgical area. The method may further comprise performing a surgical procedure with the at least one surgical instrument and material and ending detection and tracking of the at least one surgical instrument and material within the surgical area. The method may further comprise displaying at least one indication of location status of the at least one surgical instrument.

Claims (48)

1. A computer-implemented method of detecting and tracking the location of one or more objects, including surgical instruments and/or surgical material, during a surgical procedure involving at least one surgical incision, the method comprising:

receiving sensor data from at least one light detecting and ranging (LIDAR) sensor to identify and track at least one object within a surgical area;

responsive to identifying the at least one object, determining, by at least one machine learning algorithm trained to recognize surgical incisions within the surgical area and objects within the surgical incisions, and to recognize obstructions preventing viewing of the surgical incisions and objects, at least one piece of orientation information of the at least one identified object in two dimensions;

transmitting at least one piece of orientation information to at least one display;

responsive to detecting a crossing of the at least one identified object into the at least one surgical incision, determining, by the at least one machine learning algorithm, that the at least one identified object is within the at least one surgical incision;

responsive to detecting a crossing of the at least one identified object out of the surgical incision, determining, by the at least one machine learning algorithm, that the at least one identified object is outside the at least one surgical incision;

identifying, by the at least one machine learning algorithm, a change in color of the at least identified one object; and

responsive to the identifying the change in color, displaying at least one location indication of the at least one identified object within the at least one surgical incision, and at least one alert notifying operating room personnel that the at least one identified object that is unaccounted for.

2. The method of claim 1 , further comprising:

tracking the at least one object within the surgical area, the tracking beginning responsive to recognizing of the at least one object within the surgical area, and ends responsive to recognizing that the at least one object no longer is within the surgical area.

3. The method of claim 1 , wherein the at least one object comprises one or more of at least one surgical instrument, at least one surgical material, and at least one personnel.

4. The method of claim 1 , wherein the sensor data comprises one or more at least one additional viewpoint and at least one additional angle of at least one object.

5. A computer program embodied on a non-transitory computer-readable medium, said computer program comprising computer-readable instructions which, when run on hardware, cause the hardware to perform the method of claim 1 .

6. A computer-implemented method of detecting and tracking the location of at least one object, including surgical instruments and/or surgical material, during a surgical procedure involving at least one surgical incision, the method comprising:

tracking the at least one object within a surgical area using at least one light detecting and ranging (LIDAR) sensor to identify, by at least one machine learning algorithm trained to recognize surgical incisions and objects within surgical incisions, and to recognize obstructions preventing viewing of the surgical incisions and objects, the at least one object;

responsive to recognizing the at least one object within the surgical area, initiating the surgical procedure with the at least one object;

responsive to detecting a crossing of the at least one identified object into the at least one surgical incision, determining, by the at least one machine learning algorithm, that the at least one identified object is within the at least one surgical incision;

responsive to detecting a crossing of the at least one identified object out of the surgical incision, determining, by the at least one machine learning algorithm, that the at least one identified object is outside the at least one surgical incision;

responsive to detecting that the at least one object no longer is within the surgical area, ending the surgical procedure, and ending detection and tracking of the at least one object within the surgical area; and

displaying at least one indication of location status of the one or more objects.

7. The method of claim 6 , wherein:

the at least one indication of the location status comprises at least one alert notifying operating room personnel of at least one surgical instrument or surgical material that is unaccounted for.

8. A computer program embodied on a non-transitory computer-readable medium, said computer program comprising computer-readable instructions which, when run on hardware, cause the hardware to perform the method of claim 6 .

9. The method of claim 6 , wherein:

the at least one indication of the location status comprises at least one alert notifying operating room personnel that all surgical instruments and surgical materials used during the surgical procedure are accounted for.

10. The method of claim 6 , wherein:

the at least one indication of the location status comprises a checklist of each detected object.

11. The method of claim 6 , wherein:

the at least one object comprises one or more of at least one surgical instrument, at least one surgical material, and at least one personnel.

12. The method of claim 6 , wherein:

the tracking begins responsive to the recognizing of the at least one object within the surgical area, and ends responsive to recognizing that the at least one object no longer is within the surgical area.

13. The method of claim 1 , wherein:

the at least one location indication comprises at least one alert notifying operating room personnel that all surgical instruments and surgical materials used during the surgical procedure are accounted for.

14. The method of claim 1 , wherein:

the at least one location indication comprises a checklist of each detected object.

15. The method of claim 1 , wherein:

the at least one identified object comprises one or more of at least one surgical instrument, at least one surgical material, and at least one personnel.

16. The method of claim 2 , further comprising:

responsive to determining that the at least one LIDAR sensor no longer is detecting the at least one detected object,

tracking the at least one detected object based on sensor data from at least one other sensor.

17. The method of claim 1 , wherein:

responsive to detecting a blocked line-of-sight between the LIDAR sensor and the at least one object, acquiring data from at least one additional sensor to track the at least one object.

18. The method of claim 17 , wherein:

the detecting the blocked line-of-sight comprises determining that a predetermined amount of the at least one surgical incision is blocked for a predetermined period of time.

19. The method of claim 18 , wherein:

the predetermined amount is 20% and the predetermined period of time is two seconds.

20. The method of claim 17 , wherein:

the at least one additional sensor is a LIDAR sensor.
