Calculus removing support and calculus removing device

Abstract

The invention discloses a calculus removing support and a calculus removing device, and belongs to the technical field of medical instruments, the calculus removing support comprises: a body having an open state and a storage state; in the opening state, the body comprises at least two flange components, and the flange components are stacked to form a layered calculus removing structure; the guiding end is connected to the far end of the body. The flange component is formed in the open state to be fully attached to the inner wall of an organ at a calculus part, so that when the calculus removing support moves in a lumen of the organ, the layered calculus removing structure can fully clean the lumen and smoothly take out the calculus; and in the extraction process, negative pressure can be generated in the pipe cavity at the far end, small calculi at the far end are taken out, the calculi extraction efficiency is improved, and then the calculi extraction rate is effectively increased. The calculus removing device has wide applicability, can be applied to calculus removing operations of human beings and animals, can be used for calculus removing of bile ducts, and can also be applied to calculus treatment of ureters or other parts.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a stone extraction support and a stone extraction device. Background technique [0002] Stones are relatively common diseases, such as bile duct stones, ureteral stones, etc., which do great harm to human health and seriously affect the quality of life. After the occurrence of stones, treatment should be taken in time to get rid of the disease. [0003] At present, there are two main types of stone-removing instruments used in stone surgery: one is a balloon, which inflates the balloon at the stone site and then pulls out the balloon to take out the stone. However, when the balloon removes small stones, there are In the case of incarceration at the outlet, it is difficult to remove the stones after incarceration, resulting in unclean removal of the stones; the other is the mesh basket, which stretches into the stone area and binds the stones so that they can ...

Problems solved by technology

[0003] At present, there are mainly two types of stone-removing instruments used in stone surgery: one is a balloon, which is inflated at the stone site and then pulled out to take out the stone. In the case of incarcerated stones at the exit, it is not easy to remove the stones after being incarcerated, resulting in unclean removal of the stones; the other is a mesh basket, which stretches into the stone area and binds the stones so that they can be taken out. However, for smaller In the narrow space of the internal pipeline, it is difficult to accurately wrap and restrain the stones, which will also lead to the situation that the stones cannot be removed cleanly
