Stone lithotripter for urology departments

Abstract

The invention provides a stone lithotripter for urology departments, and relates to the technical field of medical care equipment. The stone lithotripter includes a cutting shell, storage cylinders, acorrugated connecting pipe and a turning tail pipe; the cutting shell is in threaded connection with the storage cylinder; the corrugated connecting pipe is fixedly connected to the right end of thestorage cylinder; the turning tail pipe is fixedly connected to the other end of the corrugated connecting pipe; the part, close to the left end, on the inner sidewall of the cutting shell is fixedlyconnected to a first sliding rail; the inner side of the first sliding rail is movably connected to a cutting base; and the inner side of the cutting base is fixedly connected to a cutting structure.Through the adoption of a micro-motor, the structure of a pushing disc and a pushing block can be driven to push a fixing rod, and swinging can be generated between the storage cylinders on the two sides of the corrugated connecting pipe and the turning tail pipe, so that directions can be changed; and the stone lithotripter is simple in structure and convenient in control, so that convenient using of the stone lithotripter can be realized.

Description

technical field [0001] The invention relates to the technical field of medical care equipment, in particular to a urology calculus lithotripsy instrument. Background technique [0002] Urinary tract calculi are one of the most common urological diseases. Urinary tract calculi are formed in the kidney and bladder. There are significant differences in the formation mechanism, etiology, stone composition and epidemiology of upper urinary tract calculi and lower urinary tract calculi. Most road stones are calcium oxalate stones. Magnesium ammonium phosphate stones are more common in bladder stones than in upper urinary tract. The theory of nucleation, stone matrix and crystal inhibitory substances are the three most basic theories of stone formation, and the most effective treatment for stones It is crushed and taken out with a stone pulverizer. [0003] When the applicant applied for the present invention, after searching, it was found that the Chinese patent disclosed "a urol...
