Urinary calculus removing instrument for urinary surgery

Abstract

The invention belongs to the technical field of medical equipment, and particularly relates to a urinary calculus removing instrument for urinary surgery. The urinary calculus removing instrument comprises a shell, an expansion assembly, an operation assembly, a calculus grabbing assembly and a calculus crushing laser, wherein an end cover is fixedly arranged on the left side wall of the shell, anair pump is fixedly arranged on the left side of the top of the shell, an air pipe channel is formed in the shell, a calculus removing channel is formed in the middle of the inner wall of the shell,the expansion assembly is fixedly arranged at the right side end of the shell, the operation assembly is inserted into the middle of the inner wall of the shell, is located in the middle of the innerwall of the calculus removing channel, and comprises an adjusting end cover, a pull rod, an adjusting seat and a connecting pipe, the pull rod is inserted into the middle of the left side wall of theadjusting end cover, and the right side end of the adjusting end cover is in threaded connection with the adjusting seat. The urinary calculus removing instrument has the comprehensive effects that the urethra can be effectively expanded, rapid and effective calculus grabbing can be facilitated, and meanwhile, the urinary calculus removing instrument is simple and convenient to operate.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a device for removing stones from urinary tract stones in urology. Background technique [0002] Stones are solid lumps formed in the duct lumen or luminal organs (such as kidney, ureter, gallbladder or bladder, etc.) in the human or animal body. They are mainly found in the gallbladder, bladder and renal pelvis, and can also be found in the pancreatic duct, In the lumen of salivary ducts, etc. Stones are composed of inorganic salts or organic matter. There is generally a core in the stone, which is composed of exfoliated epithelial cells, bacterial masses, parasite eggs or worms, fecal matter or foreign matter, and inorganic salts or organic matter are deposited on the core layer by layer. Due to the different organs involved, the stone formation mechanism contains different components, shapes, textures, and effects on the body. In general, stones can cause luminal ...

AI Technical Summary

Problems solved by technology

[0003] The urethral calculus removal device in the prior art cannot effectively expand the urethra, resulting in the inconvenience of removing the stone and increasing the pain of the patient. At the same time, the operation is cumbersome during the stone-grabbing operation, which reduces the work efficiency. Therefore, it is necessary to develop a Urology Urinary Tract Stone Removal Instrument
