초록

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, th...
