Embodiment Construction

[0025] In order to enable those skilled in the art to better understand the technical solutions in the embodiments of the present invention, and to make the above-mentioned purposes, features and advantages of the embodiments of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention are described below in conjunction with the accompanying drawings The program is described in further detail.

[0026] Please refer to figure 2 and Figure 4 The thrombus aspiration catheter provided by the embodiment of the present invention includes a catheter body and a guide wire lumen 8 arranged at the advancing end of the catheter body. The suction chamber 3 communicates. During the treatment process, the thrombus aspiration catheter reaches the lesion of the patient under the guidance of the guide wire, and the thrombus in the lesion enters the catheter body through the suction hole 7 under the negative pressure of the ex...

Abstract

The invention discloses a thrombus aspiration catheter which comprises a catheter main body and a guide wire chamber (8) arranged at an advancing end of the catheter main body, wherein the catheter main body is provided with an aspiration chamber (3); the guide wire chamber (8) is located in the inner side at the far end of the aspiration chamber (3) and is communicated with the aspiration chamber (3); a guide wire enters the guide wire chamber (8), passes through the aspiration chamber (3) and leaves away from the catheter main body at a joint (1). The thrombus aspiration catheter according to the technical scheme can solve the problems of low aspiration speed and easiness in aspiration chamber blocking caused by the smaller radial cross section areas of aspiration hole and aspiration chamber of the thrombus aspiration catheter in the prior art. The invention also provides a thrombus aspiration device.

Description

technical field [0001] The invention relates to a medical device, in particular to a thrombus suction catheter. The present invention also relates to a thrombus aspiration device having the above-mentioned thrombus aspiration catheter. Background technique [0002] In human blood vessels, especially in the supply vessels in the region of the coronary arteries, there are often obstructions such as deposits, atherosclerotic plaques, clots, etc. These obstructions can block or interrupt blood flow. The above-mentioned obstructions in the vessels supplying the area of ​​the coronary arteries may lead to serious sequelae such as infarction. Rapid removal of these obstructions is an essential therapeutic step in the treatment of such patients. [0003] Intracutaneous coronary intervention (PCI) is the first choice for the treatment of acute ST-segment elevation myocardial infarction (STEMI), which is of great significance in reducing the size of infarction, protecting cardiac f...
