<p>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.</p> |
