动脉粥样硬化主要是由于脂质沉积在动脉的血管内膜而发生的多种病变，是全身系统性、进展性疾病。当形成的粥样斑块影响正常血流时就会产生所支配区域组织的缺血症状。而且，所形成的粥样斑块可能破裂，引起血栓，造成整条血管的完全或不完全闭塞，导致的临床表现也随着器官的不同而不同，如心脏缺血主要表现为心绞痛或心肌梗死，脑血管则表现为脑供血不足、脑梗死甚至脑溢血，下肢动脉表现为剧烈疼痛或间歇性跛行。治疗该类疾病最主要的方法是恢复被斑块或血栓阻断的血流，既能够减轻甚至消除症状，又能够改善远期预后。Atherosclerosis is mainly a variety of lesions that occur due to lipid deposition in the intima of arteries. It is a systemic and progressive disease throughout the body. Ischemia of the innervated area occurs when atheromatous plaques form that interfere with normal blood flow. Moreover, the formed atherosclerotic plaque may rupture, causing thrombus, resulting in complete or incomplete occlusion of the entire blood vessel, resulting in different clinical manifestations with different organs, such as cardiac ischemia mainly manifested as angina pectoris or myocardial infarction Cerebral vessels manifest as cerebral insufficiency, cerebral infarction or even cerebral hemorrhage, and arteries of the lower extremities manifest as severe pain or intermittent claudication. The most important way to treat such diseases is to restore the blood flow blocked by plaque or thrombus, which can not only reduce or even eliminate symptoms, but also improve the long-term prognosis.
目前，针对粥样斑块的去除，除了药物治疗外，还可通过血管影像的引导，使用旋切与旋磨装置，将动脉硬化斑块从血管壁上切下或磨碎，通过导管排出体外。At present, for the removal of atherosclerotic plaque, in addition to drug treatment, it is also possible to use rotary cutting and rotary atherectomy devices to cut or grind atherosclerotic plaque from the blood vessel wall under the guidance of vascular images, and then pass it out of the body through a catheter .
然而现有的治疗方式无法直观、准确且清晰地显现出病变血管，因此无法在实时可视的条件下有效地处理动脉硬化斑块，不仅如此，还容易对血管的正常部位造成损伤。However, the existing treatment methods cannot intuitively, accurately and clearly display the diseased blood vessels, so they cannot effectively deal with the atherosclerotic plaques under real-time visualization conditions, not only that, but also easily cause damage to the normal parts of the blood vessels.
因此，基于以上问题，本发明提供了一种动脉粥样硬化切除装置，用于在实时可视的条件下进行动脉斑块旋切手术，能降低旋切对正常部位损伤的风险。Therefore, based on the above problems, the present invention provides an atherosclerosis resection device, which is used to perform rotary atherosclerosis surgery under real-time visualization conditions, which can reduce the risk of damage to normal parts caused by rotary atherectomy.
