A clip for aneurysm surgery has been designed with several unique features. The coil spring is fully hidden and protected within two hub sections so that it cannot be handled or become entrapped in tissue. The clip is milled from a piece of solid stock of nonmagnetic stainless steel to the desired size and shape by a computer milling process, thus avoiding the stresses and structural weaknesses caused by the bending, curling, and milling needed to prepare clips made from wire or sheet metal. The only means of opening the clip is by applying pressure to the solid milled surfaces, thus the spring cannot be weakened or bent by squeezing it or by trauma applied to the clip. The clip may be grasped in either a clip applier that holds the clip in one fixed position or in an applier that allows the clip to be rotated through an arc of 180 degrees.
一种用于动脉瘤手术的夹子具有几个独特的特征。螺旋弹簧完全隐藏并保护在两个毂部内，这样它就不会被触碰或卡在组织中。该夹子由一块非磁性不锈钢实心坯料通过计算机铣削工艺加工成所需的尺寸和形状，从而避免了由弯曲、卷曲和铣削由金属丝或金属薄板制成的夹子所产生的应力和结构弱点。打开夹子的唯一方法是对实心铣削表面施加压力，因此弹簧不会因挤压或对夹子施加的外力而变弱或弯曲。该夹子可以被夹在将夹子固定在一个固定位置的夹钳中，也可以被夹在允许夹子旋转180度弧的夹钳中。
