Description

Technical Field

[0001] The invention relates to an extractor, in particular to a drilling type digestive tract stone extractor. Background Art

[0002] A solid mass formed in the lumen of a duct or a cavity organ (such as the kidney, ureter, gallbladder or bladder) in the human or animal body. It is mainly found in the gallbladder, bladder, and renal pelvis, and can also be found in the lumen of the pancreatic duct, salivary duct, etc. Stones are composed of inorganic salts or organic matter. There is generally a core in the stone, which is composed of desquamated epithelial cells, bacterial clumps, parasite eggs or worm bodies, feces or foreign matter, and inorganic salts or organic matter are deposited layer by layer on the core. Due to the different organs affected, the mechanism of stone formation contains different components, shapes, textures, and effects on the body. In general, stones can cause obstruction of the lumen, affect the discharge of fluid from the affected organs, and cause symptoms such as pain, bleeding, or secondary infection.

[0025] In the drilling-type digestive tract stone extractor, the medical staff holds the handle 1, moves the sleeve 6 together with the clamping mechanism 7 into the patient's body, and places the stone in the clamping mechanism 7. The medical staff then uses the clamping mechanism 7 to clamp and fix the stone. The medical staff then turns on the driving mechanism 2, so that the driving mechanism 2 drives the crushing mechanism 3 to rotate. The medical staff then pushes the sliding mechanism 5 by hand, so that the sliding mechanism 5 drives the driving mechanism 2 together with the crushing mechanism 3 to move along the direction of the stone, that is, the crushing mechanism 3 performs a crushing process of drilling a hole first and then grinding the stone.
