Thrombus aspiration system

Abstract

The invention discloses a thrombus aspiration system. The thrombus aspiration system comprises a thrombus aspiration catheter and a blood bottle connected with the thrombus aspiration catheter in a matched mode. Because the ultra-thin pipe wall, wide cavity and single-cavity piping design is adopted in the thrombus aspiration catheter, thrombus aspiration can be smoothly and efficiently carried out. Because the outer edge of the far-end face of a tapered catheter section is in the fillet shape, the whole thrombus aspiration catheter can enter the vessel easily, and injury to the human body can be reduced. Because elliptical side holes are spirally distributed in the far end, large thrombi in the vessel can be easily and smoothly aspirated, the situation that the large-sized thrombi can not be aspirated is avoided, the thrombi in the vessel can be completely aspirated, and the best treatment effect is achieved. Blood aspirated from the human body during an operation flows into the blood bottle, the aspirated thrombi are filtered out through a thrombus filter screen in the blood bottle, the filtered blood can be transfused into the human body again, and therefore the autologous blood can be quickly and effectively utilized and the adverse effects like contamination of allogeneic blood to a patient is avoided.

Description

technical field [0001] The invention relates to a medical device, in particular to a thrombus suction system. Background technique [0002] Interventional medicine has been clinically applied for 30 years. It is an important treatment method in cardiovascular, cerebrovascular, peripheral vascular, tumor, or non-vascular fields. One of the diagnostic techniques. At present, the most widely used are cardiac interventional therapy, neurological interventional therapy, cerebrovascular interventional therapy, tumor, peripheral blood vessel and non-vascular lumen interventional therapy. [0003] With the accumulation of clinical data, the application value of thrombus aspiration catheter has gradually been recognized. At present, thrombus suction catheters with different structures have been developed in the international field to suck thrombus in the peripheral blood vessels of the human body. The injury caused a lot of inconvenience to the operation process, and the operation...

AI Technical Summary

Problems solved by technology

At present, thrombus aspiration catheters with different structures have been developed successively in the international field to aspirate thrombus in the peripheral blood vessels of the human body. The injury caused a lot of inconvenience to the operation process, and the operation effect was limited

[0004] At present, most thrombus aspiration catheters on the market use double-lumen tubes, which are the suction lumen and the guide wire lumen respectively. The guide wire lumen of some products is outside the suction lumen. The disadvantage of this design is that it increases the catheter Cross-sectional area; some products have guide wire lumen inside the suction lumen and only have one suction hole at the head end, which limits the ability of the catheter to suck thrombus

[0005] During interventional treatment, only the thrombus suction catheter is used to suck out the thrombus in the peripheral blood vessels of the human body, and at the same time, a large amount of blood is sucked out, so that it is necessary to send allogeneic blood to the patient to replace the lost blood, which may cause Pollution and other adverse reactions, and for patients, the cost of allogeneic blood is also high
