Stone removal flusher for nephrology department

Abstract

The invention relates to the technical field of medical instruments, in particular to a nephrology department calculus removal flusher which comprises a shell, a flow guide mechanism and a flushing fluid circulation mechanism. A finger profiling groove and a supporting pipe are arranged on the left side of the shell; the flow guide mechanism is arranged on the left side of the shell and comprises a flushing pipe and a backflow pipe arranged on the inner side of the flushing pipe in a sleeving mode. And the flushing fluid circulating mechanism is used for feeding flushing fluid into the flushing pipe and leading out the flushing fluid from the return pipe. The angle of the flushing pipe can be adjusted, holding is convenient, flushing and waste liquid recycling are synchronously conducted, and using is convenient.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a stone removal washer for nephrology. Background technique [0002] Kidney stones refer to the crystals formed in the kidneys by inorganic salts in the body. They are mostly caused by the imbalance of crystal metabolism in the body. They mostly occur in young and middle-aged people. They can be found through X-ray examination in clinical medicine. [0003] In the prior art, shock waves or lasers are generally used for lithotripsy, and then surgical forceps are used to remove large pieces of debris. Small pieces of debris need to be cleaned with a lithotripsy flusher, and then the debris will be washed with the waste liquid. Exhaust. At present, the existing stone extraction flushing device is generally composed of a single-section double-layer tube. The outer tube body is used for flushing, and the inner tube is used for the discharge of waste liquid and debris. The stru...

Problems solved by technology

[0003] In the prior art, shock waves or lasers are generally used for lithotripsy, and then surgical forceps are used to remove large pieces of debris. Small pieces of debris need to be cleaned with a lithotripsy flusher, and then the debris will be washed with the waste liquid. Exhaust. At present, the existing stone extraction flushing device is generally composed of a single-section double-layer tube. The outer tube body is used for flushing, and the inner tube is used for the discharge of waste liquid and debris. The structure is simple and the cost is low, but the single-section tube body is not convenient for medical care. The grip and operation of the personnel, and generally need to cooperate with the use of the external pump body to work, and then it is not convenient to use, and at the same time, it cannot filter the stone debris, which is easy to cause equipment failure and affect the service life of the equipment. Therefore, we propose a Nephrology Lithology Irrigator
