Urinary stone breaking device of urinary surgery

Abstract

The invention belongs to the technical field of medical instruments, and particularly relates to a urinary stone breaking device of a urinary surgery. Aiming at the problems that a larger wound is brought to a patient and stone cannot be clearly treated, a following scheme is provided. The urinary stone breaking device is characterized by comprising an access rod, wherein a round inner tube is arranged in one end of the access rod; the inner wall of the round inner tube is connected with a piston in a sliding and inserting way; the outer wall of one side of the piston is welded with a telescopic rod; a limiting nut is fixedly arranged in the middle position of the outer wall of one end of the access rod; threaded connection is formed between the limiting nut and the telescopic rod; the outer wall of one end, which is far away from the access rod, of the telescopic rod is welded with a connecting plate. The urinary stone breaking device disclosed by the invention is capable of thoroughly breaking stones of a patient, eliminating hidden dangers during a stone breaking process of the patient, enabling a treated position of the patient to have stronger visual observation performance, creating a better environment for stone breaking operation of the patient, preventing broken stone residues from remaining in a urinary system, and eliminating the follow-up hidden danger of forming stones again.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a lithotripsy device for urinary tract stones in urology. Background technique [0002] Stones are solid lumps formed in the lumen of ducts or lumens of luminal organs (such as kidneys, ureters, gallbladder or bladder, etc.) in humans or animals. It is mainly found in the gallbladder, bladder, and renal pelvis, and can also be found in the cavities of pancreatic ducts and salivary ducts. 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 mechanism of stone formation includes different components, shapes, textures, and effects on the body. In general, stones can cause luminal obstruc...

Problems solved by technology

Existing urinary system calculus lithotripsy devices often cause a large trauma surface when treating calculi, which brings great pain to patients, and the calculi are not treated cleanly, and gravel residues remain in the urinary system, leaving The hidden danger of subsequent formation of stones
