ABSTRACT:
A continuous flow urological endoscopic apparatus includes an endoscope having a reciprocatively-mounted treating device mounted within a sheath thereof. Pump devices establish continuous flow of fluid into and out of the interior of the body cavity to be treated via delivery and return conduits, respectively. According to one aspect of the invention, the return conduit inlet is positioned near the outermost protracted position of the treating device so that the flow of fluid is away from the objective lens of a telescope mounted within the endoscope, thereby enhancing visibility greatly. According to another aspect of the invention, a pressure sensing device is mounted within the sheath for detecting fluid pressure within the body cavity, and an electric conductor conveys signals indicative of such internal pressure within the body cavity, for safety purposes. A control circuit responds to the signals for de-activating the pump device when the fluid pressure within the body cavity exceeds a predetermined unsafe value of pressure.
