背景技术Background technique
脑血管疾病位居人类死亡原因的第三位，每年有超过200万人死于中风。无论世界不同地区或不同种族，脑血管意外都是死亡和致残的主要原因。我国每年新发完全性脑中风患者120万—150万人，死亡80万—100万人，存活者中约75%致残，5年内复发率高达41%。美国每年有50万人发病，其中15万人死亡，存活者中需要医疗照顾的200余万人。脑血管疾病严重威胁着人类的生命健康，中风后出现的偏瘫等后遗症，不仅给患者身心造成极大的痛苦，而且给社会和家庭带来巨大的精神和经济负担。Cerebrovascular disease is the third leading cause of human death, and more than 2 million people die of stroke every year. Cerebrovascular accidents are a leading cause of death and disability regardless of world region or ethnicity. In my country, there are 1.2 million to 1.5 million new complete stroke patients every year, and 800,000 to 1 million deaths. About 75% of the survivors are disabled, and the recurrence rate within 5 years is as high as 41%. Every year, 500,000 people in the United States get sick, 150,000 of them die, and more than 2 million survivors need medical care. Cerebrovascular disease is a serious threat to human life and health. The sequelae such as hemiplegia after stroke not only cause great physical and mental pain to patients, but also bring huge spiritual and economic burdens to society and families.
颈动脉内膜剥脱术（CEA）是切除增厚的颈动脉内膜粥样硬化斑块，预防由于斑块脱落引起脑卒中的一种方法，它通过切除动脉内膜上的粥样硬化斑块，以达到通畅血管、恢复大脑供血的目的，从远期效果来看，该手术防治脑中风优于药物治疗。已被证明是防治缺血性脑血管疾病的有效方法。在国外已开展50年的颈动脉内膜剥脱术是一种将关注脑血管病的重点前移，预防脑梗塞的疏通式手术。一般这一手术是在患者已出现短暂性脑缺血、脑血栓等临床症状之后,通过该手术可以将因斑块导致狭窄的颈动脉恢复正常，在直视下将这些粥样斑块切除，从而降低它们脱落而发生脑血管意外的风险。Carotid endarterectomy (CEA) is a method to remove thickened carotid intima atherosclerotic plaque and prevent stroke caused by plaque shedding. , in order to achieve the purpose of unblocking the blood vessels and restoring the blood supply to the brain. From the perspective of long-term effects, this operation is better than drug treatment in the prevention and treatment of stroke. It has been proven to be an effective method for preventing and treating ischemic cerebrovascular diseases. Carotid endarterectomy, which has been carried out for 50 years abroad, is a dredging operation that shifts the focus of attention to cerebrovascular diseases and prevents cerebral infarction. Generally, this operation is performed after the patient has clinical symptoms such as transient cerebral ischemia and cerebral thrombosis. Through this operation, the carotid artery stenosis caused by plaque can be restored to normal, and these atheromatous plaques can be removed under direct vision. Thereby reducing the risk of cerebrovascular accidents due to their detachment.
颈内动脉内膜剥脱术的术野有许多重要血管神经等结构，术中需要持续吸引渗血，以保持术野清晰。目前手术用的常规吸引器均为长管型结构，需要一名助手手持操作，存在如下缺点：1.占用人手，经常对术者操作产生阻碍；2.吸引中有时会对血管壁及周围的重要神经血管造成损伤；3.吸引操作自术野浅部向术野深部操作，吸引效果经常难以达到此手术对清洁术野的要求，相对于此类手术目前使用的其他器械的专业和精准程度，传统吸引器是专业性不足的缺点非常突出。The operative field of internal carotid endarterectomy has many important structures such as blood vessels and nerves. During the operation, it is necessary to continuously suck blood to keep the operative field clear. At present, the conventional suction devices used in surgery are all long tubular structures, which require an assistant to hold the operation, which has the following disadvantages: 1. Occupies manpower and often hinders the operation of the surgeon; 2. Sometimes the suction will damage the blood vessel wall and surrounding areas Damage to important nerves and blood vessels; 3. The suction operation is performed from the shallow part of the operative field to the deep part of the operative field. The suction effect is often difficult to meet the requirements of this operation for cleaning the operative field. Compared with the professionalism and precision of other instruments currently used in this type of operation , the traditional attractor is a very prominent shortcoming of lack of professionalism.

使用本发明的方法：手术前一天零点以后不能进食，术前两小时不能饮水。进行颈动脉内膜剥脱术先进行麻醉，麻醉成功后，在颈部做一个切口以显露颈动脉，以便于进行阻断及开放。显露颈动脉后，将本发明矩形的片状结构体1放入需要手术的颈动脉下方，并通过吸引器接头5与负压吸引器联系备用，再将在阻断的颈动脉两端插入一个塑料管（颈动脉转流管）以便在剥脱硬化段斑块的同时保证进入大脑的血流。当进行硬化斑块被剥离时，动脉血管会流出大量血液。此时开启吸引器，血液会通过片状结构体1内的多个“7”形的吸引管2另一端的吸引侧孔3吸进吸引管2，流入收集腔4内并排出，保证了手术过程中手术视野的清晰，即使有个别吸引管堵塞，其他吸引管也可继续工作。当硬化斑块被剥离后，将对动脉壁进行缝合，此时本发明可以对动脉周围的残存血液进行引流，之后撤出转流管，最后进行皮肤的缝合。本发明设计的片状结构体吸引头，应用于颈内动脉内膜剥脱术过程中持续吸引渗血，以保持术野清晰，其中多个“7”形的吸引管在手术中可以同时对手术视野内的血液进行吸引，即使有个别吸引管堵塞，其他吸引管也可继续工作，吸引侧孔的设计有效避免了吸引对血管壁及周围的重要神经血管造成损伤的风险，减少了一名助手手持操作传统吸引管对手术操作者产生的阻碍，吸引的位置位于术野最深部，渗血自然汇集处，吸引效率及术野显露效果明显提高，减少了手术时间，减少血管以及周围的重要神经血管造成损伤。Use the method of the present invention: can not take food after midnight one day before operation, can not drink water two hours before operation. Carotid endarterectomy is performed under anesthesia first. After the anesthesia is successful, an incision is made in the neck to expose the carotid artery for blocking and opening. After the carotid artery is exposed, place the rectangular sheet-like structure 1 of the present invention under the carotid artery that needs to be operated on, and connect with the negative pressure aspirator through the aspirator joint 5 for standby, and then insert a A plastic tube (carotid bypass) to allow blood flow to the brain while peeling off the hardened segment of plaque. When the hardened plaque is peeled off, the arterial vessel will bleed a large amount of blood. At this time, the suction device is turned on, and the blood will be sucked into the suction tube 2 through the suction side holes 3 at the other end of the multiple "7"-shaped suction tubes 2 in the sheet structure 1, flow into the collection chamber 4 and be discharged, ensuring safe operation. The surgical field of view is clear during the process, even if some suction tubes are blocked, other suction tubes can continue to work. After the hardened plaque is peeled off, the artery wall will be sutured. At this time, the present invention can drain the remaining blood around the artery, then withdraw the bypass tube, and finally suture the skin. The sheet-like structure suction head designed by the present invention is applied in the process of internal carotid endarterectomy to continuously suck and ooze blood so as to keep the operation field clear, wherein multiple "7"-shaped suction tubes can be used for surgical treatment at the same time. The blood in the field of view is sucked. Even if some suction tubes are blocked, other suction tubes can continue to work. The design of the suction side hole effectively avoids the risk of damage to the blood vessel wall and surrounding important nerves and blood vessels, and saves one assistant. Hand-held operation of the traditional suction tube is an obstacle to the operator. The suction position is located in the deepest part of the surgical field, where blood oozes naturally gathers, the suction efficiency and the effect of the surgical field exposure are significantly improved, the operation time is reduced, and the number of blood vessels and important peripheral nerves is reduced. Damage to blood vessels.
