A new burr-hole ring and cap are described. The threaded ring is C-shaped, holding itself in the burr hole by elastic recoil. A ventricular catheter or deep brain electrode may be passed through the slotted ring and anchored in place by means of a mushroom-shaped silicone rubber cap. The cap fills, sealing the plug. This simple two-part device, originally designed for use with a deep brain stimulator system, may also be used as a standard 5/8-inch. (16 mm) burr-hole plug.
本文介绍了一种新型的环钻环和帽。带螺纹的环呈C形，通过弹性回弹固定在环钻孔中。脑室导管或深部脑电极可穿过带槽的环，并通过蘑菇形硅橡胶帽固定到位。该帽填充后可密封塞子。这种简单的两部分装置最初设计用于深部脑刺激器系统，也可用作标准的5/8英寸（16毫米）环钻孔塞。
