Abstract

A fluid management system includes a pump configured to pump fluid through the system at a fluid flow rate. The system includes a processor including a user interface, the user interface allowing a user to input a set of system operating parameters, the processor being configured to control the pump to maintain a target fluid flow rate based on the set of system operating parameters. The system further includes a scope device coupled to the pump to deliver the fluid to a target surgical site, the scope device including an elongated shaft extending from a distal end thereof, the elongated shaft including at least one sensor, the at least one sensor transmitting sensor data relating to the target surgical site to the processor. The processor automatically signals to the pump to adjust the fluid flow rate based on the sensor data.

First claim

What is claimed is:

1. A fluid management system, comprising:
a pump configured to pump a fluid from a fluid supply source through the fluid management system at a fluid flow rate;
a processor including a user interface, the user interface allowing a user to input a set of system operating parameters, the processor determining a target therapeutic flow rate based on the set of system operating parameters, the processor being configured to control the pump to maintain the fluid flow rate within a target therapeutic fluid flow range based on the target therapeutic flow rate, the processor receiving video feedback relating to a target surgical site; and
a scope device coupled to the pump to deliver the fluid to the target surgical site, the scope device including a flexible elongated shaft extending from a distal end of the scope device, the flexible elongated shaft including at least two sensors at a distal portion of the flexible elongated shaft so that, when the distal portion of the flexible elongated shaft is positioned adjacent to the target surgical site, the at least two sensors are positioned within a body lumen adjacent to the target surgical site, the at least two sensors transmitting sensor data relating to the target surgical site to the processor,
wherein the processor automatically signals to the pump to adjust from pumping the fluid at the target therapeutic flow rate to pumping the fluid at a different flow rate for a predetermined time period based on the video feedback, wherein at an end of the predetermined time period, the processor is configured to automatically signal to the pump to revert to pumping the fluid at the target therapeutic flow rate.

2. The system of claim 1 , wherein one of the at least two sensors is a pressure sensor.

3. The system of claim 1 , further comprising a heating assembly, the heating assembly configured to heat the fluid to a target temperature.

4. The system of claim 1 , wherein the processor further includes a display screen configured to display the fluid flow rate and the sensor data in real time.

5. The system of claim 4 , wherein if the processor detects that the fluid flow rate is outside of the target therapeutic fluid flow range, a visual alert is displayed on the display screen.

6. The system of claim 1 , wherein one of the at least two sensors is a temperature sensor.

7. The system of claim 1 , wherein the fluid supply source is a fluid bag.

8. The system of claim 1 , further comprising a weight sensor for measuring a weight of the fluid supply source in real time.

9. The system of claim 1 , wherein each of the target therapeutic flow rate and the different flow rate is greater than zero.

10. A fluid management system, comprising:
a pump configured to pump a fluid from a fluid supply source through the fluid management system at a first fluid flow rate selected for a therapeutic purpose;
a processor configured to control the pump; and
a scope device coupled to the pump to deliver the fluid to a target surgical site, the scope device including an elongated shaft extending from a distal end thereof, the elongated shaft including a camera, the camera transmitting video feedback relating to the target surgical site to the processor,
wherein the processor includes image recognition software to detect variations in brightness or color pixilation in the video feedback and automatically signals to the pump to adjust from pumping the fluid at the first fluid flow rate to pumping the fluid at a second fluid flow rate for a predetermined time period based on the variations in the brightness or the color pixilation to improve images from the camera, wherein at an end of the predetermined time period, the pump is configured to revert to pumping the fluid at the first fluid flow rate.

11. The system of claim 10 , wherein the processor includes a user interface allowing a user to input a set of system operating parameters.

12. The system of claim 10 , wherein the processor includes a display screen configured to display the video feedback and at least one of the first fluid flow rate or the second fluid flow rate in real time.

13. The system of claim 10 , wherein the scope device further includes a temperature sensor located on the elongated shaft.

14. The system of claim 10 , further comprising a heating assembly, the heating assembly configured to heat the fluid to a target temperature.

15. The system of claim 10 , wherein the fluid supply source is a fluid bag.

16. The system of claim 10 , further comprising a weight sensor for measuring a weight of the fluid supply source in real time.

17. The system of claim 10 , wherein each of the first fluid flow rate and the second fluid flow rate is greater than zero.
