一种用于血管钙化破碎治疗的微孔电极A microporous electrode for the treatment of vascular calcification and fragmentation

技术领域technical field

本发明属于医疗器械领域，涉及一种用于血管钙化破碎治疗的微孔电极。The invention belongs to the field of medical devices, and relates to a microporous electrode used for the treatment of vascular calcification and fragmentation.

背景技术Background technique

血管钙化是指钙质物沉积在血管壁的一种病变，其会导致血管壁变硬，顺应性降低，也易于引发心肌缺血、左心室肥大、心力衰竭、血栓形成、斑块破裂等致死率与致残率较高的疾病。血管钙化经常贯穿于各种复杂的血管病变，且钙化病变往往伴随血管成角、扭曲病变。同时，钙化病变部位对血管扩张的反应较差。Vascular calcification refers to a disease in which calcium deposits on the blood vessel wall, which can lead to the hardening of the blood vessel wall and reduce its compliance. It is also prone to myocardial ischemia, left ventricular hypertrophy, heart failure, thrombosis, plaque rupture and other death diseases with high rates of disability and disability. Vascular calcification often runs through various complex vascular lesions, and calcified lesions are often accompanied by angulation and distortion of blood vessels. At the same time, calcified lesions were less responsive to vasodilation.

处理血管钙化病变的传统方法主要包括：非顺应性球囊、切割球囊、刻痕球囊、斑块旋磨术，准分子激光。这些方法通常只能适用于轻、中度的钙化病变，只能对浅层钙化进行处理，而对重度、深层钙化无能为力。甚至还存在引发冠状动脉夹层、冠状动脉穿孔、心动过缓及房室传导阻滞、冠状动脉痉挛、慢血流/无复流、远端栓塞现象等并发症的风险。可以看到，对于血管钙化，临床仍存在较大的痛点，有较多未被满足的需求。The traditional methods of treating vascular calcification lesions mainly include: non-compliant balloon, cutting balloon, scoring balloon, rotational atherectomy, and excimer laser. These methods are usually only applicable to mild and moderate calcified lesions, and can only deal with superficial calcifications, but cannot do anything for severe and deep calcifications. There is even a risk of complications such as coronary dissection, coronary perforation, bradycardia and atrioventricular block, coronary spasm, slow flow/no-reflow, and distal embolism. It can be seen that for vascular calcification, there are still major clinical pain points, and there are many unmet needs.

液相脉冲放电等离子体技术是一种利用在水中高压脉冲放电进而产生等离子体的技术。伴随着液相脉冲放电等离子体的生成，还会产生冲击波和声波等机械波。将液相放电装置放入血管中，利用液相脉冲放电产生的冲击波和声波破碎血管钙化层，不仅可实现血管钙化传统治疗方法的效果，同时冲击波及声波还可直达深层钙化区域进行钙化层破碎。同时，由于液相脉冲放电冲击波及声波与血管等人体组织为柔性接触，因此不会对正常器官组织造成损伤。Liquid phase pulse discharge plasma technology is a technology that uses high voltage pulse discharge in water to generate plasma. Along with the generation of liquid-phase pulse discharge plasma, mechanical waves such as shock waves and acoustic waves are also generated. The liquid phase discharge device is placed in the blood vessel, and the shock wave and sound wave generated by the liquid phase pulse discharge are used to break the vascular calcification layer, which can not only achieve the effect of the traditional treatment method of vascular calcification, but also can directly reach the deep calcification area to break the calcification layer. . At the same time, because the liquid-phase pulse discharge shock wave and sound wave are in flexible contact with human tissues such as blood vessels, they will not cause damage to normal organs and tissues.

现有的血管内钙化的血管内冲击波技术及装置的电极结构复杂，造价高昂，且难以制造。The electrodes of the existing intravascular shock wave technology and device for intravascular calcification are complex in structure, expensive to manufacture, and difficult to manufacture.
