A kind of mesh basket with high stability for stone extraction

Abstract

The invention discloses a mesh basket with high stability for taking out stones, which belongs to the technical field of medical devices, and comprises a sleeve, the side end surface of the sleeve is fixedly connected to the end surface on the side close to the connecting shaft through the basket guide core, and A side plate seat is provided at a position corresponding to the connecting shaft inside the basket guide core. In the present invention, through the mutual cooperation of the designed basket guide core, connecting shaft, piston disc, second sliding sleeve and elastic support device, it is possible to avoid the problem of difficulty in transportation at corners inside the pipeline tissue, and at the same time , It is also convenient for the basket guide core to cover the inner stones, and it is convenient for the basket guide core to wrap the inner stones, the effect is good, the use is convenient, and the practicability is strong, and more inner stones can be taken out in one operation. , not only simplifies the operation procedures of medical personnel, but also reduces the side effects of patients' treatment, has strong practicability, is conducive to popularization and use, and can also avoid excessive pressure on the inside of pipeline tissues.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a mesh basket with high stability for taking out 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, mainly found in the gallbladder, bladder, and renal pelvis, but also in the pancreatic duct and salivary gland In the cavity of the catheter, etc., the stones are composed of inorganic salts or organic substances. There is usually a core in the stones, which is composed of exfoliated epithelial cells, bacterial masses, parasite eggs or worms, feces or foreign objects, and the inorganic salts or organic substances are layered. On the deposition core, due to the different organs involved, the stone formation mechanism contains different components, shapes, textures, and effects on the body. Generally speaking, stones...

Problems solved by technology

[0004] The purpose of the present invention is: in order to solve some disadvantages in the current process of using the mesh basket for calculi, the single amount of taking is limited. It not only increases the operating procedures of medical staff, but also easily increases the side effects of patient treatment, and when the driving force is used to deform the net basket, it is easy to cause the net basket to be damaged due to excessive pulling force, and also It will increase the problem of too much internal pressure on the pipeline tissue, and a mesh basket with high stability for stone removal is proposed
