Abstract
The utility model relates to a spring needle for extradural puncture, which is composed of a hollow needle core, a spring chamber and a needle tube. At the time of extradural cavity puncture, whether the extradural cavity puncture is successful or not can be accurately judged by operators according to movement situation of a cylinder body arranged in the spring chamber and whether the negative pressure appears or not in a water storage pipe. The utility model has the advantages of easy fabrication and convenient operation. The utility model is favorable for teaching.
Description
The invention belongs to medical device technology
The spring anesthesia spinal needle is the apparatus that is used for epidural space anesthesia.At present, domestic and international employed anesthesia spinal needle (Tuohy people's pin) is made up of needle tubing and nook closing member.Its tip is sharp keen, wear out spinal dura mater easily and cause puncture failure, and nook closing member has only and supports needle tubing and prevent that soft tissue from stopping up the effect of needle tubing, and whether successful this pin does not possess can provide puncture sign for the operator.Judge the puncture success or not, many experience and feels with the operator, clinical " ligamenta flava is broken through sense " commonly used and negative pressure test also are difficult for judgement sometimes, and cause that the anesthesia error happens occasionally.
The purpose of this utility model is intended to overcome above-mentioned deficiency, provide a kind of have promptly that showing puncture and successfully indicate can not wear out spinal dural spring anesthesia spinal needle again.
The novel spring anesthesia spinal needle that is achieved in that is by needle tubing (1), hollow nook closing member (2), and spring housing (3), spring (4), spring base (5), spring cup (6) is formed.Hollow nook closing member (a 2) afterbody welding Cylinder (7), an aperture (8) is bored in Cylinder (7) side, can insert water pipe (9) on the aperture (8), hollow nook closing member (2) tip is drilled with two symmetric limbers (10), and limbers (10) communicate with water pipe (9) by the Cylinder (7) of hollow nook closing member (2) afterbody.The Cylinder (7) of hollow nook closing member (2) afterbody is stayed in the spring housing (3), contacts with spring base (5) under the effect of spring (4), is positioned at spring housing (3) middle part.There are two symmetric observation ports (11) at spring housing (3) middle part, is convenient to the operator and observes the situation of movement of Cylinder (7) and the negative pressure appearance in the water pipe (9).Spring (4) inserts in the spring base (5), in the lump in loading spring chamber (3), fixing by spring cup (6), (2 are combined as a whole with spring housing (3) to make hollow nook closing member, insert in the needle tubing (1), the front end (12) of spring housing (3) is connected with needle tubing (1) afterbody (13), and expose hollow nook closing member (2) tip.Needle tubing (1) tip ramp is 45 ° and coincide good with hollow nook closing member (2) tip exposed parts.In the process of implementing cavum epidural puncture,, illustrate that the tip of hollow nook closing member (2) has contacted ligamenta flava if Cylinder (7) moves backward.Can continue inserting needle this moment, when the tip of needle tubing (1) penetrates ligamenta flava, Cylinder (7) in the observation port (11) moves forward and produces simultaneously negative pressure appearance rapidly, and the liquid in the water pipe (9) is inhaled into intracavity, and this moment, the operator can judge the cavum epidural puncture merit of having accomplished.
Claims (3)
1, a kind ofly forms,, it is characterized in that it is combined as a whole by hollow nook closing member (2) and spring housing (3) and the tip ramp angle is that 45 ° needle tubing (1) is formed for the spring anesthesia spinal needle that epidural anesthesia uses by needle tubing and nook closing member.
2, according to the described spring anesthesia spinal needle of claim 1, it is characterized in that being drilled with two symmetric limbers (10) on hollow nook closing member (2) tip, a welding Cylinder (7) on the afterbody, an aperture (8) is bored in Cylinder (7) side, and water pipe (9) is arranged on the aperture (8).
3, according to the described spring anesthesia spinal needle of claim 1, it is characterized in that being equipped with in the spring housing (3) spring (4), spring base (5), spring cup (6), there are two symmetric observation ports (11) at the middle part.
