自从出现了显微神经外科,手术治疗颅内动脉瘤有了飞速发展,因此产生了大量的与之有关的器械,动脉瘤夹便是其中之一。经过长时间的筛选,目前使用的主要有三种类型即Yasargil型,Sugita型的Sundt—Kees型。由于动脉瘤生长的大小和形状的不同而需用不同的动脉瘤夹,目前这三种动脉瘤夹有一个共同特点就是前端两脚密闭和顶端很尖。因此这些夹的顶端很紧地闭合在一起象夹刀,显然夹的顶端会损伤周围组织。夹住动脉瘤的方便方法是把动脉瘤的颈与毗邻的组织分开,接着水平放入动脉瘤夹夹住瘤颈。有些病例水平放夹难度很大,也是不可能的,垂直放夹是唯一的选择,在这些病例,使用那些顶端很尖的夹子是很危险的,因此作者建 Since the emergence of micro-neurosurgery, surgical treatment of intracranial aneurysms has been rapid development, resulting in a large number of related equipment, aneurysm clip is one of them. After a long period of screening, there are mainly three types currently used: the Yasargil type and the Sugita type Sundt-Kees type. Due to the different size and shape of aneurysm growth need different aneurysm clip, at present the three aneurysm clip has a common feature is the front two legs closed and the top is very sharp. Therefore, the tops of these clips tightly close together like a knife, apparently the top of the clip can damage the surrounding tissue. A convenient way to pinch the aneurysm is to separate the neck of the aneurysm from the adjacent tissue and then place the aneurysm clip horizontally to clamp the neck. In some cases, it is very difficult and impossible to place clips horizontally. Vertical placement is the only option. In these cases, it is dangerous to use those topmost clips, so the author
