High-stability mesh basket for taking out calculus

Abstract

The invention discloses a high-stability mesh basket for taking out calculus, and belongs to the technical field of medical instruments, the high-stability mesh basket comprises a sleeve, the side end face of the sleeve is fixedly connected with the end face of the close side of a connecting shaft through a mesh basket guide core, and a side plate seat is arranged at the position, corresponding to the connecting shaft, of the inner side of the mesh basket guide core. According to the invention, under the mutual cooperation of the designed structures such as the mesh basket guide core, the connecting shaft, the piston disc, the second sliding sleeve and the elastic supporting device, the problem of difficult conveying at a corner in a pipeline tissue can be avoided, and meanwhile, the mesh basket guide core can conveniently cover the inner stone and conveniently wrap the inner stone, The high-stability mesh basket is good in effect, convenient to use and high in practicability, more internal calculi can be extracted in one-time operation, operation procedures of medical staff are simplified, side effects of treatment of a patient are reduced, the high-stability mesh basket is high in practicability and beneficial to popularization and application, and meanwhile, overlarge compression force on the interior of a pipeline tissue can be avoided.

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 block formed in the lumen of a duct in a human or animal body or in the lumen of a luminal organ (such as the kidney, ureter, gallbladder, or bladder, etc.), 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, sto...

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
