Thrombus removing sleeve and thrombus removing balloon catheter assembling kit

Abstract

The invention discloses a thrombus removing sleeve and a thrombus removing balloon catheter assembling kit for treating thromboembolic diseases in a percutaneous puncture cavity. The thrombus removingsleeve comprises a thrombus removing passage catheter with a thrombus leading-in umbrella and an umbrella cover releasing assembly, wherein the umbrella cover releasing assembly is used for controlling the folding compression or release of the thrombus leading-in umbrella. A thrombus removing balloon catheter is a single-cavity balloon catheter, and is matched with a guide wire through a side wall guide wire hole of a guide section, so that the cross section area of the thrombus removing balloon catheter is reduced; the thrombus removing balloon catheter is matched with the thrombus removingsleeve, so that thrombus in arteries and veins can be effectively and rapidly removed; and the thrombus removing sleeve is particularly suitable for use under the condition of high-load thrombus embolism of the arteries and veins of limbs, so that a patient is benefited.

Description

technical field [0001] The invention relates to a thrombus removal interventional surgical instrument, in particular to a thrombus removal sleeve, a thrombus removal balloon catheter and a thrombus removal balloon catheter assembly kit. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may constitute prior art. During the process of realizing the present invention, the inventors have found at least the following problems in the prior art. [0003] With the aging of the population and changes in lifestyle, the incidence of thromboembolic diseases is increasing year by year. Includes arterial embolism, arterial thrombosis, and venous thromboembolism. For mild thromboembolism, medical anticoagulant and thrombolytic therapy can be used, but for acute arterial embolism and venous embolism with heavy thrombus load, medical treatment cannot quickly and effectively restore vascular patency.

AI Technical Summary

Problems solved by technology

This surgical method is laborious and time-consuming, and the surgeon and the patient need to receive long-term high-dose radiation exposure, and thrombus incarcerated catheters are often blocked under negative pressure, and the thrombus attached to the wall is difficult to suck out, and the effect of thrombus removal is not ideal.

The second is to use equipment such as Angojet to mechanically break up the thrombus and suck the thrombus through fluid mechanics, etc., but the special external control equipment and special suction catheter that need to be used are extremely expensive, and the broken thrombus can cause red blood cell destruction, and hemoglobinuria occurs after surgery kidney damage, which greatly limits its clinical application

However, if the diameter of the thrombectomy access catheter is increased, the incidence of complications and operational difficulty will increase significantly during arterial puncture
