Abstract

The invention discloses a lithangiuria calculus removal device used in the urinary surgery. The lithangiuria calculus removal device comprises a calculus removal cannula, a guiding wire and a calculuscrushing electrode, wherein an operating base is arranged at the head end of the calculus removal cannula; an oblique passage tube is arranged on the calculus removal cannula; the head end of the oblique passage tube obliques towards the operating base; a guiding tube is embedded in the calculus removal cannula; the inner cavity of the oblique passage tube communicates with the guiding tube; a push-and-pull handle is arranged on the operating base; one end of the guiding wire penetrates through the calculus removal cannula to be connected with the push-and-pull handle; the other end of the guiding wire is connected with a calculus removal cord net; and the calculus crushing electrode enters the guiding tube through the oblique passage tube and stretches out of the calculus removal cannula. The lithangiuria calculus removal device greatly improves removal of larger calculus in a urethra, is simple in operation, shortens the operation time to alleviate the pain of a patient and is a more ideal lithangiuria calculus removal device used in the urinary surgery.

Description

technical field [0001] The invention relates to the technical field of medical care devices, in particular to a device for removing stones from 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 l...
