    • A spinal needle system that signals entry into the epidural space tip stabilizes the dura mater. The system includes a cannula (17) having at a distal tip (52) an annular surface surrounding a terminal port and at least one barb (50) projecting at an angle from the annular surface of the cannula for grasping and controlling the tissue. Each barb (50) is formed having a sharp edge configured to grasp the tissue as the tubular member is rotated about its longitudinal axis. One implementation of the system includes a plurality of unidirectional barbs (50) spaced around the annular surface of the cannula (17). The system includes an indicator mechanism that gives a visual and a tactile indication of when the cannula encounters and penetrates tissue. The system facilitates the appropriate placement of an epidural or subdural catheter or patch of any kind.
    • 信号进入硬膜外腔尖端的脊髓针系统稳定硬脑膜。 该系统包括套管(17),其具有在远侧末端(52)处围绕终端口的环形表面和与套管的环形表面成一角度突出的至少一个倒钩(50),用于抓握和控制该组织。 每个倒钩(50)形成为具有锋利的边缘,其被构造成在管状构件围绕其纵向轴线旋转时抓住组织。 该系统的一个实施方式包括围绕套管(17)的环形表面间隔开的多个单向倒钩(50)。 该系统包括指示器机构,其给出了插管何时接触并穿透组织的视觉和触觉指示。 该系统有助于适当放置硬膜外或硬膜下导管或任何种类的贴片。

    • The disposable, sterile spinal syringe set without mandrin consists of three components, namely; a syringe (6), a dental needle (1) and a normal needle (2). The dental needle (1) may be manufactured with an adapter part (5) made of plastics, in order to facilitate its attachment to the syringe (6). Dental needle (1) is a spinal needle without mandrin. The inner surface of the adapter can be flat, threaded or luer-locked. The main body (3) of the dental needle can be manufactured in various gauges and lengths of a special iron whereas its tip (4) can be made as straight, inclined, with a pin-tip or can be formed obliquely. In an alternative embodiment of using the disposable sterile spinal syringe set without mandrin, a normal needle (3) is not employed whereas the disposable sterile syringe (6) pre-filled with medicament for a single-use and a dental needle (1) which is a spinal needle without mandrin are used as one piece.
    • 一次性无菌脊髓注射器组不含mand rin,由三部分组成: 注射器(6),牙科针(1)和普通针(2)。 牙科针(1)可以制造有由塑料制成的适配器部件(5),以便于其连接到注射器(6)。 牙针(1)是无针孔的脊髓针。 适配器的内表面可以是平的,螺纹的或鲁尔锁定的。 牙针的主体(3)可以以各种规格和长度的特殊铁制造,而其尖端(4)可以制成为直的,倾斜的,具有针尖或可以倾斜地形成。 在使用没有mandrin的一次性无菌脊柱注射器组件的替代实施例中,不使用普通针(3),而一次性无菌注射器(6)预填充用于单次使用的药物和牙针(1),其中 是没有mand骨的脊髓针用作一体。
