Problems solved by technology

[0003] At present, the effect of using an extracorporeal lithotripter to crush large stones in the digestive tract is not ideal, and the stone crushing effect is poor, which reduces the treatment progress of patients. In view of the above defects, it is necessary to design a drill-type digestive tract stone extractor

Abstract

The invention discloses a drilling type extractor for calculi in a digestive tract. The drilling type extractor comprises a handle, a driving mechanism, a crushing mechanism, a connecting rod, a sliding mechanism, a sleeve body and a clamping mechanism. In use of the drilling type extractor, a medical worker uses the clamping mechanism to clamp and fix a calculus and then uses the crushing mechanism to successively drill and grind the calculus, so the medical worker can conveniently smash the calculus with a large size in the body of a patient; and therefore, calculus smashing effect is improved and the treatment progress of the patient is accelerated in virtue of the drilling type extractor.

Description

technical field [0001] The invention relates to a remover, in particular to a drilling type remover for digestive tract stones. Background technique [0002] A solid mass formed in the lumen of a duct or in a lumen of a luminal organ (such as the kidney, ureter, gallbladder, or bladder, etc.) in a human or animal body. It is mainly found in the gallbladder, bladder, and renal pelvis, and can also be found in the lumens 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 stone formation mechanism contains different components, shapes, textures, and effects on the body. In general, stones can cause luminal obstruction, affect the drainage of fluid ...
