技术领域technical field
本发明涉及一种医疗器械，具体涉及一种血栓抽吸系统。The invention relates to a medical device, in particular to a thrombus suction system.
背景技术Background technique
介入医学在临床上应用已有三十年历史，无论在心血管、脑血管、周围血管、肿瘤，或非血管领域内都是一项重要的治疗手段，被誉为与内科、外科并列的三大诊疗技术之一。目前最为广泛应用的有心脏介入治疗，神经介入治疗，脑血管介入治疗，肿瘤，外周血管以及非血管管腔的介入治疗。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.
随着临床数据的积累，血栓抽吸导管的应用价值也逐渐得到认可。目前，国际领域相继开发出了不同结构的血栓抽吸导管，对人体外周血管内的血栓进行抽吸，但由于其结构和材料所限，导管的抽吸能力差，进入血管时容易对人体造成损伤，给手术过程造成了很多的不便，手术效果有限。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 effect was limited.
目前，市场上的血栓抽吸导管多采用双腔管，分别为抽吸管腔及导丝管腔，部分产品导丝管腔在抽吸管腔外部，这种设计弊端在于增大了导管的截面积；部分产品导丝管腔在抽吸管腔内部且只拥有头端的一个抽吸孔，限制了导管抽吸血栓能力。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.
在介入治疗时，仅采用血栓抽吸导管将人体外周血管内的血栓吸出，同时还伴有大量血液被吸出，这样即需要向病人输送异体血液来补充所流失的血液，由此可能会带来污染等不良反应，并且对病人来说，所需异体血液费用也很高。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 very high.
