颈动脉内膜剥脱术吸引头 Carotid endarterectomy suction head

技术领域 FIELD

[0001] 本发明涉及一种医疗器械,具体涉及一种颈动脉内膜剥脱术吸引头,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。 [0001] The present invention relates to a medical instrument, particularly to a carotid endarterectomy suction head, internal carotid endarterectomy applied continuously during bleeding suction to maintain a clear operative field.

背景技术 Background technique

[0002] 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。 [0002] cerebrovascular disease ranked third leading cause of death in humans, there are more than 2 million people die from stroke each year. 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。 Whether the main reason for the different parts of the world or of different races, cerebrovascular accidents are death and disability. 我国每年新发完全性脑中风患者120万一150万人,死亡80万一100万人,存活者中约75%致残,5年内复发率高达41%。 Our annual new complete 120 stroke patients in case of 150 million people, in case of the death of 80 million people, about 75% of survivors maimed, the recurrence rate as high as 41% within 5 years. 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。 50 million Americans each year, the disease, in which 15 people died, survivors need medical care of more than 200 million people. 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 a serious threat to human life and health, hemiplegia after stroke and other complications, not only caused great suffering to patients with physical, mental, and spiritual and bring huge economic burden to society and the family.

[0003] 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。 [0003] carotid endarterectomy (CEA) is the removal of intima thickening of carotid atherosclerotic plaque, a method for the prevention of stroke due to the loss caused plaque, which cut through the arterial intima porridge-like plaque, vascular smooth in order to achieve an object of restore blood supply to the brain, the long-term effect, the prevention and cure of stroke than drug therapy. 已被证明是防治缺血性脑血管疾病的有效方法。 It has proven to be an effective method for prevention and treatment of ischemic cerebrovascular disease. 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。 50 years have been carried out abroad carotid endarterectomy is a way to focus forward cerebrovascular disease prevention and clear the surgery cerebral infarction. 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。 This surgery is usually after the clinical symptoms of transient ischemic, cerebral thrombosis has occurred in the patient, because the plaque can cause narrowing of the carotid artery through the normal procedure, under direct vision these atherectomy, thereby reducing them from falling and cerebral vascular accident risk.

[0004] 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。 [0004] carotid endarterectomy surgical field there are a number of important structures such as blood vessels and nerves, intraoperative bleeding needs to continue to attract, to maintain a clear surgical field. 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。 Currently conventional surgical aspirator are long tubular structure, needs an assistant hand-held operation, the following disadvantages: 1 occupied manpower, the surgeon often hinder the operation; 2 sometimes will attract the blood vessel wall and around. important neurovascular damage; 3 suction operation from the operative field shallow to deep surgical field part of the operation, a suction effect is often difficult to achieve this surgical requirements for clean surgical field, relative to other instruments such procedures currently used by professional and accuracy traditional suction is the shortcoming professional very prominent.
