Abstract

A tissue resection system includes an endoscope, a surgical drape, a surgical instrument, a control console, at least one collection container, at least one fluid source, and tubing for fluid flow. The tissue resection system includes one or more fluid outflow management components for establishing and/or maintaining adequate vacuum pressure within the tissue resection system.

First claim

What is claimed is:

1 . A surgical fluid management system comprising:
a surgical drape; a collection container; a fluid outflow tube coupled to the surgical drape and the collection container for withdrawal of exudate from the surgical drape into the collection container; and a valve disposed within the fluid outflow tube, the valve having a closed position for preventing flow into the collection container from the surgical drape and an open position for enabling flow through the surgical drape into the collection container.

2 . The surgical fluid management system according to claim 1 , wherein the valve is a stopcock valve.

3 . The surgical fluid management system according to claim 1 , further comprising:
a control console including a vacuum pump assembly; and a vacuum line coupled to the vacuum pump assembly and the collection container for providing suction through the fluid outflow tube.

4 . The surgical fluid management system according to claim 3 , wherein the control console controls the valve.

5 . The surgical fluid management system according to claim 1 , wherein the surgical drape includes a body defining a cavity therein, and a second end of the body is coupled to the fluid outflow tube.

6 . A surgical fluid management system comprising:
a surgical drape including a body defining a cavity therein; a collection container; a fluid outflow tube coupled to the surgical drape and the collection container for withdrawal of exudate from the surgical drape into the collection container; and a membrane extending across the cavity of the surgical drape to close a fluid flow path between the surgical drape and the fluid outflow tube.

7 . The surgical fluid management system according to claim 6 , wherein the membrane is formed from a dissolvable or bioerodible polymer.

8 . The surgical fluid management system according to claim 6 , further comprising:
a control console including a vacuum pump assembly; and a vacuum line coupled to the vacuum pump assembly and the collection container for providing suction through the fluid outflow tube.

9 . A surgical fluid management system comprising:
an endoscope; a surgical drape; a first collection container; a second collection container; a first fluid outflow tube coupled to the endoscope and the first collection container for withdrawal of fluid from the endoscope into the first collection container; a second fluid outflow tube coupled to the surgical drape and the second collection container for withdrawal of fluid from the surgical drape into the second collection container; and a vacuum pump assembly including a vacuum line selector for controlling suction through the first and second fluid outflow tubes.

10 . The surgical fluid management system according to claim 9 , further comprising:
a first vacuum line coupled to the vacuum pump assembly and the first collection container for providing suction through the first fluid outflow tube; and a second vacuum line coupled to the vacuum pump assembly and the second collection container for providing suction through the second fluid outflow tube.

11 . The surgical fluid management system according to claim 9 , wherein the vacuum line selector includes a valve.

12 . The surgical fluid management system according to claim 10 , wherein the vacuum line selector is coupled to an actuator that is manually adjustable to open and close the first and second vacuum lines.

13 . The surgical fluid management system according to claim 10 , wherein the vacuum line selector is motorized and programmed to automatically open and close the first and second vacuum lines.

14 . The surgical fluid management system according to claim 9 , further comprising:
a fluid source; and a fluid inflow tube coupled to the endoscope and the fluid source for enabling delivery of fluid from the fluid source into the endoscope.

15 . The surgical fluid management system according to claim 14 , further comprising:
a pressure pump assembly including a pressure line selector for controlling pressure on the fluid source and one of the first or second collection containers.

16 . The surgical fluid management system according to claim 15 , further comprising:
a first pressure line coupled to the pressure pump assembly and the fluid source for pressurizing fluid in the fluid source; and a second pressure line coupled to the pressure pump assembly and the one of the first or second collection containers for drawing negative pressure through the one of the first or second collection containers.

17 . The surgical fluid management system according to claim 16 , wherein the pressure line selector includes a valve for diverting pressure to the first or second pressure line.

18 . The tissue resection system according to claim 16 , wherein the pressure line selector is motorized and programmed to automatically utilize either the first or second pressure line.

19 . The surgical fluid management system according to claim 16 , wherein the pressure line selector is configured to divert pressure into the second pressure line to aid the vacuum pump assembly in maintaining negative pressure in at least one of the first or second collection containers.
