Description
技术领域 technical field
本发明涉及一种医疗器械，特别涉及一种颅内出血早期血肿微创清楚系统。 The invention relates to a medical device, in particular to a minimally invasive clearing system for early hematoma of intracranial hemorrhage.
背景技术 Background technique
脑出血是目前的常见病、多发病，起病急、病情重，致残率和死亡率高。全国每年新发脑出血病人有80万-120万。就重庆市来讲，来院治疗时间从发病到手术平均都在六个小时左右。颅内的出血已形成韧性块状凝固物质，颅内压力非常大，患者随时有生命危险。目前普遍使用的治疗方式是开颅手术，取出血肿，但该手术危险系数高，切口创面大，手术时间长，不易恢复健康，术后易留后遗症。使患者的生命和健康不能得到保障。 Cerebral hemorrhage is a common disease, frequently-occurring disease, acute onset, serious condition, high disability rate and mortality rate. There are 800,000 to 1.2 million new cerebral hemorrhage patients in the country every year. As far as Chongqing is concerned, the average time for treatment at the hospital is about six hours from onset to surgery. The intracranial hemorrhage has formed a tough blocky solidified substance, the intracranial pressure is very high, and the patient's life is in danger at any time. At present, the commonly used treatment method is craniotomy to remove the hematoma, but the risk factor of this operation is high, the incision wound is large, the operation time is long, it is not easy to recover, and sequelae are easy to leave after operation. The patient's life and health cannot be guaranteed.
近年来，随着微创医学技术的发展，一次性颅内血肿粉碎穿刺针被广泛应用于颅脑出血的救治，大大减轻了患者的痛苦。通过金属导针穿过颅腔内，进行引流，但目前的脑出血微创清除手术器械尚有许多不完善的地方，如：手术导管和引流管内径偏小(3mm)，血肿碎吸器对血肿的碎吸效果不好，不论是自动引流还是主动抽吸，都很容易被血凝块阻塞。并且在微创等血肿应用过程中，发现脑血肿大由坚固的血液凝块及少部分的半固体液态组成。目前液态可经轻抽吸清除，坚固的血凝块只能经过旋转刀片等机械性搅吸清除。机械方式容易引起再出血及脑组织损伤。 In recent years, with the development of minimally invasive medical technology, disposable intracranial hematoma pulverized puncture needles have been widely used in the treatment of craniocerebral hemorrhage, greatly reducing the pain of patients. Metal guide pins pass through the cranial cavity for drainage, but the current minimally invasive surgical instruments for cerebral hemorrhage still have many imperfections, such as: the inner diameter of the surgical catheter and the drainage tube is too small (3mm), and the hematoma shatter and aspirator is not effective for hematoma. The broken suction effect is not good, whether it is automatic drainage or active suction, it is easy to be blocked by blood clots. And in the application process of minimally invasive hematoma, it was found that cerebral hematoma is composed of solid blood clot and a small part of semi-solid liquid. At present, the liquid state can be removed by light suction, and the solid blood clot can only be removed by mechanical agitation such as rotating blades. Mechanical methods can easily cause rebleeding and brain tissue damage.
