<p>PROBLEM TO BE SOLVED: To remove/wash a urolith deposided on a toilet and a bent pipe part on the periphery. SOLUTION: Innumerable balls are provided on a rotary head part through a bearing at the tip part of the machine, a tube is passed through a flexible rod provided with through- holes on front and back and composed of the chain of perforated balls and small cut pipes with an inner cable for motor drive passed through it and air bags are sectioned at the front and the back. A faucet is formed inside a sewage discharge pipe by a front balloon and a chemical for softening the urolith is injected inside the inner wall of an organ. At the time, the measure of saving the volume of the injecting chemical is taken by filling air in a back balloon as well and the generation of a chemical effect is waited for. A special brush is equipped at the tip part of the cable, the rotation of a motor is supplied to the cable and it is gradually removed. Also, for the development of the introduction machine of an endoscopic camera, the characteristics of the machine are utilized, the passage of the camera is formed by providing one pipe together and the camera can be inserted even to the back bottom part of the organ. The take-out/take-in conversion of filling air is operated by the changeover of a rotary valve and detergent is applied by operating a liquid injection valve cock.</p> |
