Abstract

A surgical fluid management system includes a source of surgical media, a surgical instrument, a first pump, one or more filters, a second pump, and a controller. The first pump is operatively coupled between the source of surgical media and the surgical instrument. The one or more filters are configured to filter bodily discharge from a surgical site. The second pump is operatively coupled between the one or more filters and the first pump. The controller is in electrical communication with the first pump and the second pump to control the first and second pumps.

Claims

1. A surgical fluid management system, comprising:

a source of surgical media;

a surgical instrument;

a first pump operatively coupled between the source of surgical media and the surgical instrument;

at least one filter configured to filter at least portions of bodily discharge from a surgical site, wherein the at least one filter includes a first filter supported within a catch basin and a second filter positioned remote from the catch basin, the first filter selectively removable from the catch basin and configured to separate tissue from the bodily discharge;

a second pump operatively coupled between the at least one filter and the first pump;

a controller in electrical communication with the first pump and the second pump to control the first and second pumps; and

at least one fluid conduit extending between at least two of;

the surgical instrument, the catch basin, the at least one filter, the first pump, the second pump, and combinations thereof, and

wherein the at least one fluid conduit forms a closed loop.

2. The surgical fluid management system of claim 1, further including a pressure sensor in electrical communication with the controller and configured to sense fluid pressure within the surgical instrument.

3. The surgical fluid management system of claim 1, further including a check valve operatively coupled to the at least one filter.

4. The surgical fluid management system of claim 3, wherein the check valve is operatively coupled between the at least one filter and the first pump.

5. The surgical fluid management system of claim 1, wherein at least one of the first and second pumps is a peristaltic pump.

6. The surgical fluid management system of claim 1, wherein the controller is configured to receive at least one manual input.

7. The surgical fluid management system of claim 6, wherein the at least one manual input is selected from the group consisting of pumping pressure, start fill cycle, end fill cycle, start surgical cycle, end surgical cycle and combinations thereof.

8. The surgical fluid management system of claim 1, wherein the second pump directs surgical media disposed in the at least one filter toward the source of surgical media when the controller runs an end cycle.

9. The surgical fluid management system of claim 8, further including a fluid level sensor coupled to the at least one filter and configured to determine a fluid level within the at least one filter.

10. The surgical fluid management system of claim 1, further including a third pump coupled to the at least one filter and in electrical communication with the controller.

11. The surgical fluid management system of claim 1, further including a fluid level sensor coupled to the source of surgical media and configured to determine an amount of fluid within the source of surgical media.

12. The surgical fluid management system of claim 1, further including at least one ultrasonic sensor in electrical communication with the controller.

13. A surgical fluid management system, comprising:

a source of surgical media;

a surgical instrument;

a first pump operatively coupled between the source of surgical media and the surgical instrument;

at least one filter configured to filter at least portions of bodily discharge from a surgical site, wherein the at least one filter includes a first filter supported within a catch basin and a second filter positioned remote from the catch basin, the first filter selectively removable from the catch basin and configured to separate tissue from the bodily discharge;

a second pump operatively coupled between the at least one filter and the first pump;

a controller in electrical communication with the first pump and the second pump to control the first and second pumps; and

at least one fluid conduit extending between at least two of;

the surgical instrument, the catch basin, the at least one filter, the first pump, the second pump, and combinations thereof, and

wherein at least a first portion of the at least one fluid conduit is configured to maintain surgical media therein after the controller runs an end surgical cycle to purge at least a second portion of the at least one fluid conduit.

14. A surgical fluid management system, comprising:

a source of surgical media;

a surgical instrument;

a first pump operatively coupled between the source of surgical media and the surgical instrument;

at least one filter configured to filter at least portions of bodily discharge from a surgical site;

a second pump operatively coupled between the at least one filter and the first pump; and

a controller in electrical communication with the first pump and the second pump to control the first and second pumps, wherein the controller is configured to receive at least one manual input selected from the group consisting of pumping pressure, start fill cycle, end fill cycle, start surgical cycle, end surgical cycle, and combinations thereof.
