Abstract

A thrombus removal system relates to the field of medical equipment, including an outer tube; an outer shell, an outer shell, an inner tube and an inner shell. The outer shell is connected to the outer tube; the inner tube is rotatably inserted into the outer tube, and the inner tube has a mounting portion exposed to the outer tube; the inner shell is connected to the mounting portion, and at least one of the outer shell and the inner shell is provided with Cutting edge; wherein, the inner tube is used to rotate relative to the outer tube to drive the inner shell to rotate relative to the outer shell, thereby driving the cutting edge to rotate to cut off the thrombus, and the inner shell and the outer shell can jointly define an accommodation for receiving the removed thrombus cavity. The thrombectomy system can improve the effect of thrombus treatment and reduce the probability of additional damage to the patient's body.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a thrombus removal system. Background technique [0002] Drug stents are now an important weapon against coronary thrombosis. During treatment, the stent is implanted in the body where the thrombus is located, and the thrombus is eliminated and regeneration is controlled through the slow release of drugs on the stent. However, there is a certain risk in such an operation, that is, the stent will remain in the human body, and if the stent slips or rusts, it will cause unexpected damage to the patient's body, thus there is a risk of damaging the patient's body. [0003] The inventors found that the existing stent system for treating thrombus has the following disadvantages: [0004] If the stent remains in the body, it is easy to affect the health of the patient. Contents of the invention [0005] The purpose of the present invention is to provide a thrombectomy system, which ...
