Abstract

The invention provides a novel stretchable disposable calculus removal mesh basket with a funnel. The novel stretchable disposable calculus removal mesh basket comprises a control handle, a sheath catheter and a mesh basket body. The sheath catheter is connected with the control handle and comprises a fourth catheter, a third catheter, a second catheter and a first catheter, and the fourth catheter, the third catheter, the second catheter and the first catheter are nested together sequentially from inside to outside. A fourth catheter body is structurally made of stainless steel wires, the third catheter, the second catheter and the first catheter are hollow catheters, the front end of the fourth catheter is connected with the head of the mesh basket body, the front end of the third catheter is connected with the tail of the mesh basket body in a stretchable net structure, and the front end of the second catheter is connected with the tail of the funnel which is capable of retracting or stretching. By the novel stretchable disposable calculus removal mesh basket with the funnel, the problem of poor calculus removal effects of a traditional calculus removal mesh basket in the priorart is solved.

Description

technical field [0001] The invention relates to the technical field of stone extraction net basket transformation, in particular to a novel retractable disposable stone extraction net basket with a funnel. Background technique [0002] Disposable stone removal mesh baskets currently on the market are mainly used to remove gallstones in the urethra and bile ducts or foreign objects in the upper and lower digestive tracts. Most of the mesh baskets are semicircular, headless, rotating, and there is no connecting pipeline in the middle. When in use, the mesh basket protrudes through the front-end pipeline to take out the stones. However, due to the structural design problems of the existing products, the stone removal effect is average. The stones that have been placed in the mesh basket are easy to fall out during the stone removal process, which increases the Excessively long operation time will cause serious harm to the human body. Contents of the invention [0003] The pr...
