Abstract
This invention provides an automatic irrigation and evacuation device for use in laparoscopic procedures and surgery. The device comprises a means for directing a flow of liquid and, alternatively, applying a vacuum, through a single line. In the preferred embodiment of this invention, the device provides two different positive controls for alternatively directing a flow of sterile irrigating solution and applying a vacuum through a single line passed through a laparoscope housing into a patient. The two different controls prevent confusion by the operator of the device, increasing the safety of the patient during medical procedures. The invention also optionally includes an external 'T' valve attachable to the exterior of the valve body of the present invention to provide convenient connections for a source of carbon dioxide to the laparoscope, surgical laser or both simultaneously.
