Abstract

The invention relates to the technical field of calculus treatment, in particular to a calculus removing apparatus for lithangiuria in urology. The calculus removing apparatus comprises a calculus removing pipe and a calculus removing head, wherein the calculus removing head is arranged at one end of the calculus removing pipe, an accommodating bag is arranged at the other end of the calculus removing pipe, a calculus falling passage is formed in the middle position of the inner part of the calculus removing pipe, and the accommodating bag communicates with the inner part of the calculus falling passage; and the calculus removing head comprises two shells which are symmetrically arranged, and expanding and contracting connecting pieces connected with the two shells, and a calculus breakingelectrode is also mounted on the inner side of each shell. According to the calculus removing apparatus disclosed by the invention, the calculus removing pipe extends into the urethra of a patient, the calculus removing head is used for breaking calculi, and the broken calculi slide into the inner part of the accommodating bag for storage along the calculus falling passage; in the calculus removing process, thread sleeves are driven by rotating shafts to move, and further through cooperation between first connecting members and second connecting members, the shells are driven to open and close, so that the calculus removing head can be suitable for calculi of different sizes, the calculus breaking electrodes are guaranteed to be closely attached to the calculi, and the calculus breaking effect can be improved.

Description

technical field [0001] The invention relates to the technical field of calculus treatment, in particular to an apparatus 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 lum...
