背景技术Background technique

急性脑血管疾病，又称中风、脑卒中或脑血管意外，系脑部血管或供应脑的颈部动脉的病变引起的脑局灶性血液循环障碍，并由脑部血液循环障碍导致以局部神经功能缺失为特征的疾病。根据病因、病理可将中风分为缺血性和出血性两大类，前者包括短暂脑缺血发作、局限性脑梗死；后者包括脑出血和蛛网膜下腔出血。局限性脑梗死简称脑梗死，是指因动脉血栓形成，栓子、炎症、损伤等引起局部脑组织急性缺血、坏死。其中脑血栓形成是缺血性脑血管病中常见的类型，在国家标准《中医临床诊疗术语》中，将包括脑血栓形成在内的缺血性脑血管病明确称为“缺血中风”。Acute cerebrovascular disease, also known as stroke, cerebral apoplexy or cerebrovascular accident, is a focal brain blood circulation disorder caused by a lesion in the blood vessels of the brain or the carotid arteries supplying the brain, and is caused by the blood circulation disorder in the brain to a local nerve A disorder characterized by loss of function. According to the etiology and pathology, stroke can be divided into two categories: ischemic and hemorrhagic. The former includes transient ischemic attack and localized cerebral infarction; the latter includes cerebral hemorrhage and subarachnoid hemorrhage. Cerebral infarction, referred to as localized cerebral infarction, refers to acute ischemia and necrosis of local brain tissue caused by arterial thrombosis, embolus, inflammation, injury, etc. Among them, cerebral thrombosis is a common type of ischemic cerebrovascular disease. In the national standard "Terms of Clinical Diagnosis and Treatment of Traditional Chinese Medicine", ischemic cerebrovascular disease including cerebral thrombosis is clearly called "ischemic stroke".

建立指标控制理想的活体脑缺血动物模型是研究脑缺血病理生理变化和评价有效干预措施的手段。为了解脑中风的发病机制及演变过程并实现对药物疗效的观察，在对脑中风的实验研究中亟需一种成功率高、稳定性好、操作高效、干扰因素较小的实验动物模型。凭借良好的稳定性和可重复性，脑缺血再灌注动物模型成为研究缺血性脑血管病的重要途径，帮助研究者最大程度模拟人类缺血性卒中的病变过程。Establishing an ideal living animal model of cerebral ischemia with index control is a means to study the pathophysiological changes of cerebral ischemia and evaluate effective intervention measures. In order to understand the pathogenesis and evolution process of cerebral apoplexy and realize the observation of drug efficacy, an experimental animal model with high success rate, good stability, efficient operation and less interference factors is urgently needed in the experimental research of cerebral apoplexy. With good stability and reproducibility, animal models of cerebral ischemia-reperfusion have become an important way to study ischemic cerebrovascular diseases, helping researchers to simulate the pathological process of human ischemic stroke to the greatest extent.

近年来学者们发明了多种大脑中动脉局灶性脑缺血模型的制作方法，如开颅机械闭塞法、微栓子栓塞阻断法、化学刺激诱导血栓性闭塞法、光化学诱导血栓形成法、血管内栓线阻塞法等。其中早在1986年，由日本学者Koizumi发明的线栓法制成可实现再灌注的大脑中动脉阻塞大鼠模型，因其无需开颅、创伤小、可实现再灌注，更接近人类急性脑梗死经药物溶栓后血管再通的病变过程，而引起学者们的广泛关注。In recent years, scholars have invented a variety of methods for making focal cerebral ischemia models of the middle cerebral artery, such as craniotomy mechanical occlusion, microembolism embolism occlusion, chemical stimulation-induced thrombosis occlusion, and photochemical-induced thrombus formation. , Intravascular embolism occlusion method, etc. Among them, as early as 1986, the suture method invented by Japanese scholar Koizumi made a rat model of middle cerebral artery occlusion that can achieve reperfusion. Because it does not require craniotomy, less trauma, and can achieve reperfusion, it is closer to human acute cerebral infarction. The pathological process of vascular recanalization after drug thrombolysis has attracted widespread attention of scholars.

目前被广大学者所公认的是Longa等建立的大脑中动脉缺血(MCAO)再灌注动物模型。但在具体实验操作过程中，该方法仍暴露出一些缺陷，手术中插线操作因血管走形特点易受人为因素影响，导致实验动物伤残率、死亡率高、模型成功率低等。例如：颈总动脉剪口时，由于力度和角度的操作全人为操控，切口太大便会导致颈总动脉完全断裂，切口太小会导致鱼线的插入十分困难。稍有不慎便会导致造模实验的失败，通过阅览相关文献时发现，当前仍缺乏对该模型制作过程详尽、规范、标准的操作规程，致使学习者很难按照此类文献完成模型的制备工作。The animal model of middle cerebral artery ischemia (MCAO) reperfusion established by Longa et al. is recognized by most scholars at present. However, in the specific experimental operation process, this method still exposed some defects. The thread insertion operation during the operation is easily affected by human factors due to the shape of the blood vessels, resulting in high disability rate, high mortality rate and low success rate of the model in experimental animals. For example: when cutting the common carotid artery, due to the full control of the strength and angle, the incision is too large and the common carotid artery will be completely broken, and the incision is too small and the insertion of the fishing line will be very difficult. A little carelessness will lead to the failure of the modeling experiment. After reading the relevant literature, it is found that there is still a lack of detailed, standardized, and standard operating procedures for the model making process, which makes it difficult for learners to complete the model preparation according to such literature.

When the end of the internal carotid artery 12 is squeezed, the upper elastic piece 210 and/or the lower elastic piece 220 are separated from each other by external force.

在上述实施例的基础上，进一步地，所述上弹片210和所述下弹片220大小相同，所述上弹片210和所述下弹片220的宽度均大于颈内动脉12的直径。On the basis of the above embodiment, further, the upper elastic piece 210 and the lower elastic piece 220 have the same size, and the widths of the upper elastic piece 210 and the lower elastic piece 220 are both larger than the diameter of the internal carotid artery 12 .

本实施例中，上弹片210和所述下弹片220大小相同，上弹片210和下弹片220的宽度大于颈内动脉12的直径，可以保障在上弹片210和下弹片220能够将颈内动脉12全部挤压。In this embodiment, the upper elastic piece 210 and the lower elastic piece 220 have the same size, and the width of the upper elastic piece 210 and the lower elastic piece 220 is larger than the diameter of the internal carotid artery 12, which can ensure that the upper elastic piece 210 and the lower elastic piece 220 can connect the internal carotid artery 12 Squeeze it all.

在上述实施例的基础上，进一步地，所述颈总动脉部300包括上下对称设置的上颈总动脉夹和下颈总动脉夹，所述旁孔310设置在所述上颈总动脉夹靠近颈总动脉1的进入端。On the basis of the above embodiments, further, the common carotid artery part 300 includes a superior common carotid artery clamp and an inferior common carotid artery clamp arranged symmetrically up and down, and the side hole 310 is disposed near the superior common carotid artery clamp. The entry end of the common carotid artery 1.

本实施例中，颈总动脉部300包括上下对称设置的上颈总动脉夹和下颈总动脉夹，在手术时，便于医护人员对动脉血管进行包裹，而且，旁孔310设置在所述上颈总动脉夹靠近颈总动脉1的进入端，这样，在操作的过程中，对于医护人员将上颈总动脉夹和下颈总动脉夹夹持对应的颈总动脉1、颈外动脉11和颈内动脉12的操作要求就会得到降低，手术成功的几率就可以得到提升。In this embodiment, the common carotid artery part 300 includes upper and lower common carotid artery clamps and inferior common carotid artery clamps, which are convenient for medical staff to wrap the arterial blood vessels during surgery, and the side hole 310 is set on the upper common carotid artery clamp. The common carotid artery clamp is close to the entry end of the common carotid artery 1. In this way, during the operation, for the medical staff, the upper common carotid artery clamp and the lower common carotid artery clamp clamp the corresponding common carotid artery 1, external carotid artery 11 and The operating requirements of the internal carotid artery 12 can be reduced, and the probability of successful operation can be improved.

图4为本发明实施例提供的动脉夹装置的侧视图。如图4所示，在上述实施例的基础上，进一步地，所述夹持体呈Y型设置。Fig. 4 is a side view of the arterial clip device provided by the embodiment of the present invention. As shown in FIG. 4 , on the basis of the above embodiments, further, the clamping body is arranged in a Y shape.

本实施例中，夹持体呈Y型设置，以使得夹持体与通孔的形状更加吻合，并且和颈总动脉1、颈外动脉11和颈内动脉12的三岔口的形状也更加吻合，在使用夹持体进行手术操作时候更加简便，可以根据外观的形状与动脉血管进行对应。In this embodiment, the clamping body is arranged in a Y shape, so that the clamping body is more consistent with the shape of the through hole, and is more consistent with the shape of the fork of the common carotid artery 1, external carotid artery 11 and internal carotid artery 12 , it is more convenient to use the clamp body for surgical operation, and it can correspond to the arterial vessel according to the shape of the appearance.

在上述实施例的基础上，进一步地，所述通孔内设置的内表面均设置有吸附层，所述吸附层用于吸附血管。On the basis of the above embodiments, further, the inner surface of the through hole is provided with an adsorption layer, and the adsorption layer is used for absorbing blood vessels.
