Irrigation solution re-circulating system

U.S. Patent Number: 5382229

Abstract: An irrigation solution re-circulating system comprises a reservoir of irrigation solution, a solution supply line for joining the reservoir in fluid communication with a surgery site for delivering a controlled volume, pressure, and temperature of the irrigation solution to the surgery site, and a return line for further joining the surgery site in fluid communication with the reservoir. A pump, which is preferably non-hemolyzing, is connected to the return line for returning a controlled volume of the irrigation solution from the surgery site to the reservoir. The system further comprises at least one filter connected to the return line for removing contaminants from the irrigation solution prior to return to the reservoir to permit re-circulation of the solution without impairing endoscopic visualization of the surgery site, while providing solution for expanding the surgery site to permit performance of the attendant surgical procedure.
