Description
技术领域technical field
本发明涉及心血管手术器械领域，特别涉及一种防止血管破裂的球囊及使用方法。The invention relates to the field of cardiovascular surgical instruments, in particular to a balloon for preventing blood vessel rupture and a method for using the same.
背景技术Background technique
随着生活水平的提高，冠心病成为最常见的心脏病，主要是由于冠状动脉狭窄、供血不足而引起的心肌机能障碍或器质性病变，故又称缺血性心肌病。目前，冠心病主要有药物治疗、经皮腔血管介入治疗和心外科搭桥手术三种治疗方案。经皮腔血管介入治疗因其创伤小、恢复快，能迅速消除冠状动脉狭窄，缓解心肌缺血等特点，已成为冠心病的主要治疗手段。With the improvement of living standards, coronary heart disease has become the most common heart disease, mainly due to coronary artery stenosis, insufficient blood supply caused by myocardial dysfunction or organic disease, so it is also called ischemic cardiomyopathy. Currently, there are three main treatment options for coronary heart disease: drug therapy, percutaneous luminal vascular intervention, and cardiac bypass surgery. Percutaneous transluminal vascular intervention has become the main treatment method for coronary heart disease because of its small trauma, rapid recovery, rapid elimination of coronary stenosis and myocardial ischemia.
现有的介入治疗通常利用球囊将支架送入血管狭窄的位置，再利用球囊将支架撑开，利用血管的弹性将支架固定在血管内。In the existing interventional therapy, the stent is usually delivered to the stenotic position of the blood vessel by using a balloon, and then the stent is stretched by the balloon, and the stent is fixed in the blood vessel by the elasticity of the blood vessel.
但是，由于血管内脂肪堆积的厚度不同，支架的撑开后的直径又为一定。所以，在血管内脂肪堆积较厚的位置，外侧血管的凸起较为严重，对于一些特殊人群，如老年人，其本身血管壁弹性不足，在通过支架进行支撑后，虽然血管通畅了，但是，凸起部分与未凸起部分的连接处成为脆弱点，容易出现破裂。However, due to the difference in the thickness of the fat accumulation in the blood vessel, the diameter of the stent after expansion is constant. Therefore, in the position where the fat accumulation in the blood vessel is thick, the bulge of the outer blood vessel is more serious. For some special groups, such as the elderly, the elasticity of the blood vessel wall itself is insufficient. After being supported by the stent, although the blood vessel is unobstructed, however, The junction between the raised portion and the non-raised portion becomes a weak point and is prone to breakage.
