摘要：
The proposed utility model relates to medical instruments used in urology for hydrodynamic evacuation of calculi from the renal cavity. The purpose of this device is to reduce the risk of injury to the kidney tissue during the operation to remove kidney stones by the method of percutaneous evacuation. The extractor for removing stones from the kidney cavity consists of a device body, a casing tube, a fluid inlet fitting mounted into the device body at an angle, a drainage pipe. for the withdrawal of removed calculi, mounted in the device body at an angle, bushings, washers, cap nuts located in the upper and lower parts of the housing. The flow of irrigation fluid captures renal calculi, which are removed by the flow through the outlet nozzle when the endoscope is moved until the distal end of the endoscope will be at the level of the outlet. In this case, the tube-casing remains stationary relative to the kidney wall. Dumping and storage of stone fragments in the chamber occurs through a flexible tube at the moment the distal end of the endoscope with a captured stone fragment passes by it without completely removing the endoscope and breaking the tightness of the system. Then the endoscope is again immersed in the kidney cavity to capture and remove the remaining fragments of the stone. The procedure is repeated until all stone fragments are completely removed from the kidney cavity.Предлагаемая полезная модель относится к медицинским инструментам, используемым в урологии при гидродинамической эвакуации конкрементов из почечной полости. Целью данного устройства является снижение риска травмирования тканей почки при проведении операции по удалению почечных конкрементов методом чрескожной эвакуации.Экстрактор для удаления конкрементов из полости почки состоит из корпуса устройства, трубки-кожуха, штуцера для ввода жидкости, вмонтированного в корпус устройства под углом, штуцера отводного для вывода удаляемых конкрементов, вмонтированного в корпус устройства под углом
