Litholith crushing device for urinary calculi in urinary surgery

Abstract

The invention relates to the technical field of medical apparatus and instruments, and discloses a lithotripsy device for urinary calculi in urinary surgery, the lithotripsy device comprises a console and a lithotripsy device, the lithotripsy device comprises an outer sleeve and a handle rod which are in sliding fit connection, and a lithotripsy rod main body is fixedly embedded in the tail end, facing the interior of the outer sleeve, of the handle rod; the tail end, embedded into the handle rod, of the stone crushing rod body is electrically connected with a wire through a wiring connector, the tail end, away from the wiring connector, of the wire is electrically connected with the console, second guide grooves are symmetrically embedded in the two sides of the end, away from the handle rod, of the outer sleeve, and a traction assembly is arranged between the handle rod and the sliding connecting block in a transmission connection mode. A sliding connecting block is arranged on the second guide groove in a sliding fit mode, and a blocking cover correspondingly matched with the opening of the outer sleeve is arranged on the sliding connecting block in a rotating connection mode. The stone crushing rod body can be conveniently protected, blocking of the outer sleeve by the blocking cover can be relieved while the stone crushing rod body is pushed out through the handle rod for operation, and operation is synchronous and flexible.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a lithotripsy device for urological calculi. 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 obstruction, affect ...
