    • A resealable ventriculostomy reservoir device is provided. The device includes a base having an upper and lower opening, the upper opening defining an internal reservoir well, and a cap having an open bottom portion. The device further includes a flange element having a first portion disposed within a portion of the cap and a second portion extending distally beyond the open bottom portion of the cap and adapted for detachably mating with the internal reservoir well of the base. The second portion of the flange element includes a snap fit element adapted to cooperate with a feature on the internal reservoir well to secure the flange element and the base together. A sealing element is disposed between the internal reservoir well and the flange element to provide a fluid tight seal between the base and the flange element when the base and the flange element are detachably mated.
    • 提供可重复密封的脑室造口储液装置。 该装置包括具有上开口和下开口的基部,上开口限定内部储存器井,以及具有开口底部的盖。 该装置还包括凸缘元件,该凸缘元件具有设置在盖的一部分内的第一部分,以及第二部分,其向远端延伸超过盖的开口底部并且适于与基部的内部储存器可拆卸地配合。 凸缘元件的第二部分包括卡扣配合元件,其适于与内部储存器井上的特征配合以将凸缘元件和基座固定在一起。 密封元件设置在内部储存器井和法兰元件之间,以便当基座和法兰元件可拆卸地配合时,在基座和法兰元件之间提供流体密封。

    • A device to stop the penetration of a cranial drill that is used to pierce the skull during neurosurgical procedures. The device uses a plurality of spacers that each have a body in the form of a cylinder having a bore extending therethrough with a flat disc adjacent the cylindrical body with a plurality of tabs fixed to the disk in a circumferential pattern around the bore and axially aligned therewith. The periphery of the disk having a diameter larger than the cylindrical body portion to form a gripping member. Each of the tabs having an indent positioned on an outer surface and an interior surface of the cylindrical body portion having a bead positioned around the interior diameter of the cylindrical body portion so that the indents in the tabs are adapted to engage and retain a bead of another spacer when the spacers are fitted together to define a drill stop. Each of the plurality of spacers are of different lengths than at least one of the other spacers.
    • 一种用于在神经外科手术期间用于刺穿颅骨的颅钻穿透的装置。 该装置使用多个间隔件,每个间隔件具有圆柱体形状的主体,该主体具有延伸穿过其中的孔,邻近圆柱体具有平盘,多个凸片以围绕孔的周向图形固定到圆盘上并且轴向对准 随之而来。 盘的圆周的直径大于圆柱形主体部分,以形成夹紧构件。 每个翼片具有定位在圆柱形主体部分的外表面和内表面上的凹陷,其具有围绕圆柱形主体部分的内径定位的凸缘,使得凸片中的凹口适于接合并保持 当间隔件装配在一起以限定钻头停止件时的另一间隔件。 多个间隔物中的每一个具有与其它间隔物中的至少一个不同的长度。
