Problems solved by technology

[0002] At present, holmium laser has been widely used in the medical field. The effect of holmium laser lithotripsy under percutaneous nephroscopy is better, but the stone removal speed is relatively slow, and the vision is relatively blurred during lithotripsy, which affects the speed of lithotripsy. The pressure in the renal pelvis is often high during stone clearing, increasing the risk of water absorption and the risk of toxaemia due to reflux
Therefore, it is only suitable for relatively small and easily crushed stones.

Embodiment

[0014] Embodiment: The present invention is an auxiliary device for nephroscopic treatment, that is, a laser optical fiber guide and a water suction tube, which is composed of a tube body 9 (45 cm in length) and 2 joints. One of the connectors is a straight direction connector, i.e. an optical fiber tube connector 4, which is used for connecting laser optical fibers. The size of the inner cavity of the optical fiber pipe joint 4 is 3Fr-7Fr, and the optical fiber pipe joint 4 is connected with a sealing cap II. There is a small hole in the middle of the sealing cap II, which is normally closed, allowing the optical fiber to pass through, and has the function of preventing water and gas from entering and exiting. The other is an oblique direction joint, i.e. the water suction joint 7, the size of its inner chamber is 8Fr~18Fr, and it is equipped with a control switch. The control switch is composed of a rubber hose 5 and a pipe clamp 6, and the rubber hose 5 is externally conne...

Abstract

A laser fiber guiding and water absorption tube used for a nephroscope comprises a tube body and is characterized in that two connectors are connected at one end of the tube body, the two connectors include an optical fiber connector and a water absorption connector, a sealing cap II is installed on the optical fiber connector, and a rubber tube and a controlling clip are installed on the water absorption connector. The laser fiber guiding and water absorption tube used for the nephroscope has the advantages of being an auxiliary instrument special for treatment of holmium laser lithotripsy with a percutaneous nephroscope, being capable of conducting flushing, lithotripsy and suction at the same time, increasing intelligibility of the treatment of the holmium laser lithotripsy with the percutaneous nephroscope, and being accurate in locating treatment, high in treatment speed, high in safety and few in complication.

Description

technical field [0001] The invention relates to an auxiliary device for holmium laser lithotripsy specially used for urology nephroscopes, that is, a laser optical fiber guide and water suction tube for nephroscopes. Background technique [0002] At present, holmium laser has been widely used in the medical field. The effect of holmium laser lithotripsy under percutaneous nephroscopy is better, but the stone removal speed is relatively slow, and the vision is relatively blurred during lithotripsy, which affects the speed of lithotripsy. In the process of stone clearing, the pressure in the renal pelvis is often high, which increases the risk of water absorption, and increases the risk of toxemia due to reflux. Therefore, it is only suitable for stones that are relatively small and easily crushed. Contents of the invention [0003] In order to overcome the slow speed of holmium laser lithotripsy under percutaneous nephroscopy, relatively blurred vision, excessive water ...
