Abstract

Surgical instrument tracking systems, methods and devices are described. The system can include tracking devices configured to detect location events. The tracking device can include sensors, circuits, power sources, memories, and radio interface. The tracking devices can automatically determine a location of the tracking device when the tracking device detects a location event. The tracking device can automatically transmit the location and information related to the location event to a data analytics platform. The data analytics platform can allow a user to track multiple surgical instruments and surgical instrument tray in order to accurately determine when surgical instruments should be replaced, and how efficiently the surgical instruments are used.

Claims (52)

1. A device for tracking a surgical instrument comprising:

a sensor configured to detect a location event associated with the surgical instrument;

a circuit for controlling and processing signals coming from the sensor;

a communication module for wirelessly transmitting information to an external device;

a memory for storing information coming from the circuit; and

a power source configured to supply power to sensor, the communication module, the circuit, and the memory,

wherein the device is configured to be coupled to a tray configured to hold the surgical instrument, and

wherein the device is configured to:

determine a location event reaching a threshold level;

determine a location of the device when sensor detects a location event;

compare the location to a previous location stored on the memory;

determine that the location is different from the previous location; and

in response to determining that the location is different from the previous location, wirelessly transmit, by the communication module, the location to an external system.

2. The device of claim 1 , wherein the sensor comprises at least one of: a mechanical switch, a magnetic field sensor, an accelerometer, a temperature sensor, a photosensor, a pressure sensor, a proximity sensor, or a vibrometer.

3. The device of claim 1 , wherein the location event comprises an acceleration, a change in temperature, a change in light, a change in pressure, a change in magnetic field, or a vibration.

4. The device of claim 1 , wherein the device is further configured to periodically activating the sensor to monitor the location of the device at predetermined times.

5. The device of claim 1 , wherein the device is further configured to automatically determine the location of the device in response to not detecting any location event for a period of time.

6. The device of claim 1 , wherein the device is further configured to: transmit data to a data analytics platform via at least one of: a cellular network, Wi-Fi, Bluetooth, or RFID.

7. The device of claim 1 , wherein the communication module comprises a radio interface.

8. The device of claim 1 , wherein the sensor comprises a temperature sensor, wherein the device is further configured to:

determine that a temperature has increased above a threshold temperature; and

disable power to at least one component of the device comprising at least one of: a radio interface, the memory, or a counter.

9. The device of claim 8 , wherein the device is further configured to:

determine that a temperature has decreased above the threshold temperature; and

enable power to the at least one component.

10. The device of claim 1 , wherein the location event occurs when the device is removed from an autoclave, and wherein the device is configured to:

increment, by the circuit, a counter stored in the memory; and

transmit, by the communication module, the counter to a data analytics platform.

11. A method for tracking a surgical instrument comprising using a tracking device:

configuring a sensor of the tracking device to detect a location event associated with the surgical instrument;

determining, by the tracking device using a sensor, a location event;

determining, by the tracking device, that the location event meets a threshold level;

determining, by the tracking device, a location of the tracking device when the sensor detects the location event;

comparing, by the tracking device, the location to a previous location stored in a memory of the tracking device;

determining, by the tracking device, that the location is different from the previous location; and

in response to determining that the location is different from the previous location, wirelessly transmitting, by a communication module of the tracking device, the location to an external system.

12. The method of claim 11 , where the location event comprises one or more of: an acceleration, a change in temperature, a change in light, a change in pressure, a change in magnetic field, or a vibration.

13. The method of claim 11 , further comprising:

periodically monitoring the location of the tracking device at a predetermined time interval.

14. The method of claim 11 , further comprising: configuring the communication module to automatically determine the location of the tracking device coupled to a tray if the sensor does not detect the location event for a period of time.

15. The method of claim 11 , further comprising: transmitting data to a data analytics platform via at least one of: a cellular network, Wi-Fi, Bluetooth, or RFID.

16. The method of claim 11 , further comprising:

determining that a temperature has increased above a threshold temperature; and

disabling power to at least one component of the tracking device, the at least one component comprising at least one of: a radio interface, a memory, or a counter.

17. The method of claim 16 , further comprising:

determining that the temperature has decreased above the threshold temperature; and

enabling power to the at least one component.

18. The method of claim 11 , further comprising:

incrementing, by the tracking device, a counter stored in a memory of the tracking device; and

transmitting, by the communication module, the counter to a data analytics platform.

19. The method of claim 11 , wherein the communication module comprises a radio interface.

20. The method of claim 11 , wherein the sensor comprises at least one of: a mechanical switch, a magnetic field sensor, an accelerometer, a temperature sensor, a photosensor, a pressure sensor, a proximity sensor, or a vibrometer.
