An interventional thrombus removal device

Abstract

The invention discloses an interventional thrombus cleaning device, which comprises a fixed cylinder, a fixed plate and a collection box. The fixed plate is provided with sinusoidal channels 1 and 2 which are mirror images of each other and connected to each other along the opening direction of the fixed tube. The first sinusoidal channel extends to the lowest point of the sinusoidal image along the direction close to the bottom wall of the fixed cylinder. The inner wall of the second sinusoidal channel is movably connected with a flip baffle, and the two extension mechanisms are fixedly connected with a connecting rod. The connecting rod is fixedly connected by the attracting rod, and the attracting rod moves through the first sinusoidal channel or the second sinusoidal channel. In use of the present invention, through the setting of the first sinusoidal channel and the second sinusoidal channel, the cleaning tool is extended It is a sinusoidal movement opposite to the retraction process. While reducing the damage to the blood vessel wall, it ensures that every blood vessel wall is expanded by the cleaning tool, ensuring the strength of cleaning thrombus. It is easy to use and is very worthy of promotion.

Description

technical field [0001] The invention relates to the technical field of surgical intervention equipment, in particular to an interventional thrombus cleaning device. Background technique [0002] At present, various thrombus clearing devices are usually used for the treatment of thrombotic diseases, such as using the principle of negative pressure suction to suck the thrombus into the suction catheter, or using a spiral cutter to cut and break the thrombus before suctioning. [0003] In the prior art, an interventional thrombus removal catheter with the application number "201710987911.1" includes a catheter body and a guide wire seat. The catheter body is provided with three independent suction chambers, a drug injection chamber and a guide wire chamber, and the drug is injected through the capillary. Inject into the thrombus, and then use the back and forth movement and rotation of the capillary and hair to break the thrombus, and finally collect the broken thrombus through...

AI Technical Summary

Problems solved by technology

[0004] However, there are still many defects in the prior art, such as: 1, adopt the crushing method to crush the thrombus, the capillary and the hairy filaments rotate and rub against the blood vessel wall to crush the thrombus, which is very easy to cause damage to the blood vessel wall; The method is to crush the thrombus. The broken thrombus is easy to flow with the blood, and it is easy to block the small blood vessels, which will bring secondary harm to the patient.
