Technical Field
The invention relates to the technical field of calculus treatment, in particular to a urinary surgery lithangiuria calculus removing instrument.
Background
Calculus is a solid block formed in the lumen of a catheter or a luminal organ (such as a kidney, a ureter, a gallbladder or a bladder) in a human body or an animal body, mainly found in the gallbladder, the bladder and a renal pelvis, and also found in the lumen of a pancreatic duct, a salivary gland duct and the like. Calculus is composed of inorganic salts or organic substances. Calculus generally has a core consisting of exfoliated epithelial cells, bacterial mass, parasite eggs or bodies, fecal mass or foreign matter, and inorganic salts or organic matter deposited layer by layer on the core. The mechanism of calculus formation is different in composition, shape, texture, and influence on the body, etc. depending on the organs involved. In general, calculus can cause obstruction of the lumen, affecting the drainage of fluids from the affected organ, producing symptoms such as pain, bleeding or secondary infection.
When the existing calculus smashing device for the urinary system is used for treating calculus, the calculus taking device cannot smash calculus with different sizes, so that the calculus cannot be completely treated, and calculus smashing residues remain in the urinary system, so that the hidden danger of forming calculus again later is left.
