Abstract: A user friendly, safe and efficient continuous flow irrigation endoscope having only a single housing sheath without an inner sheath. The exclusion of the inner sheath increases the effective lumen of the endoscope. A long hollow cylindrical tube, capable of performing a to and fro and rotary motion, is placed inside the housing sheath to function as an endoscopic instrument, but also to serve as a conduit for evacuating waste fluid and detached tissue pieces present inside a tissue cavity. A single inflow port located at the proximal end of the single housing sheath allows the irrigation fluid to enter the tissue cavity via the lumen of the said housing sheath. The invented endoscope system has a single inflow port, a single outflow port, without an inner sheath so that all waste fluid and tissue debris present inside cavity are evacuated via the same single outflow port. No type of feedback mechanism, such as mechanical or electrical feedback mechanism, is incorporated in the endoscope to facilitate the removal of detached tissue pieces or waste fluid.

Abstract: A system and a method for distending a body tissue cavity of a subject by continuous flow irrigation by using two positive displacement pumps, such as peristaltic pumps, one pump on the inflow side and another pump on the outflow side, such that the amplitude of the pressure pulsations created by the positive displacement pumps inside the tissue cavity is substantially dampened to almost negligible levels. The present invention also provides a method of reducing the frequency of the said pressure pulsations. The present invention also provides a method for accurately determining the rate of fluid loss, into the subject's body system, during any endoscopic procedure without utilizing any deficit weight or fluid volume calculation, the same being accomplished by using two fluid flow rate sensors.

Abstract: A continuous flow irrigation endoscope and a continuous flow irrigation fluid management system, both designed to be compatible to each other and to function as a single system. The endoscope and the fluid management system are synergistic to each other such that both enhance the efficiency of each other. The invented system allows a body tissue cavity to be distended by continuous flow irrigation so that detached tissue pieces and waste fluid present inside a body tissue cavity are continuously automatically evacuated from the tissue cavity without causing the cavity to collapse at any stage and without the need of withdrawing the endoscope of a part of the endoscope from the tissue cavity. No type of feedback mechanism, such as mechanical or electrical, or valve or valve like systems, are incorporated in the endoscope to influence or facilitate the removal of detached tissue pieces or waste fluid in any manner.

Abstract: A single handed, safe and efficient system for aspirating a surgical site. The aspirating system of the present invention allows the surgeon to aspirate a surgical site by holding the aspiration cannula constantly in the same hand, such that the other hand of the surgeon is never needed for managing or manipulating the aspiration system in any manner. The invention allows a surgical site to be aspirated in an uninterrupted manner despite blood clots and tissue debris which constantly block the tip and the lumen of the aspiration cannula.
