Lithangiuria removing device and lithangiuria removing system

Abstract

According to the lithangiuria removing device, aiming at lithangiuria wrapped and combined by magnetic fluid; broken stone wrapped or adsorbed by the magnetic fluid is loaded into a loading cavity ofa lithangiuria removing assembly through the magnetic adsorption force of a driving magnet and a calculus removing magnet, and the lithangiuria removing device is not limited by the size of the brokenstone and the position of the broken stone. The loading cavity can load as many fine calculus fragments as possible, and relatively large calculus can be directly adsorbed by the calculus removing magnet and is sucked out of the body together with the calculus removing magnet, so that the calculus removing frequency is reduced, and the calculus removing efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to a urinary stone removal device and a urinary stone removal system. Background technique [0002] Kidney and ureteral stones are the most common stones in the urinary system. The conventional treatment methods are mainly stone crushing and stone removal under the use of an endoscope. The common ones are ureteroscopic / flexible ureteroscopic lithotripsy (URL) and percutaneous nephrolithotomy (PCNL). This method usually uses a set of stone baskets to remove the broken stones. The stone basket is designed in the shape of a net bag, which is currently the most commonly used tool for blocking and removing stones. After crossing the top of the stone, it stretches out into a net shape. [0003] But, the set stone basket of this mesh structure has certain defectives. First of all, only larger crushed stones can be netted, and granular crushed stones smaller than the mesh cannot be ...

AI Technical Summary

Problems solved by technology

Moreover, the set of stone baskets can only take out about a small piece of gravel each time, which requires repeated stone removal, and the efficiency is slow, which increases the probability of the above problems.
