Description

Double-needle tube telescopiform puncture needle for nerve block and preparation method thereof
Technical field
The present invention relates to medical instruments field, more particularly to a kind of double-needle tube telescopiform puncture needle for nerve block and its system Make method.
Background technology
Ultrasound guidance nerve block technique, due to its can intuitively observe nerve and surrounding structure, puncture needle path, The advantages that diffusion of local anaesthesia decoction, it was used widely in recent years in clinical anesthesia.In single peripheral blockade, More using technology in plane, because supersonic beam only has, 1mm is wide, the target nerve seen simultaneously in same plane of ultrasound, punctures Pin is not easy to, and the degree of difficulty of real-time tracing puncture needle and target nerve, is increased with the increase of target nerve depth, with Needle angle increase, the visuality of puncture needle can reduce.Work as puncture needle（Particularly needle point）When can not be observed under ultrasound, Inserting needle process may injured nerve.At present, most scholars think that short inclined-plane pin is more difficult and penetrate perineurium, therefore advocate to use Short inclined-plane pin.But short inclined-plane pin is more blunt, it is not easy to penetrate skin and manadesma, operates and inconvenient.
The content of the invention
In view of the deficiencies in the prior art, the technical problems to be solved by the invention, which are to provide one kind and not only improved, penetrates skin Manadesma, double-needle tube telescopiform puncture needle for nerve block of injured nerve and preparation method thereof is not easy again.
In order to solve the above problems, a technical scheme of the invention is：A kind of double-needle tube telescopiform puncture needle for nerve block, Interior pin and outer pin including phase intussusception, the interior pin are formed by connecting by inner needle tube and interior adapter, and the outer pin is by outer pin Pipe and outer adapter are formed by connecting, and the inner needle tube be long inclined-plane pin, and the outer needle tubing be short inclined-plane pin, the inner needle tube with outside Needle tubing is metal hard tube；The interior adapter rear end is provided with the female groove for injecting local anaesthetics, the interior adapter front end Male tenon is provided with, the outer adapter rear end is provided with the female groove for male tenon insertion, and the male tenon lateral wall of the interior adapter is set A projection is equipped with, the female groove madial wall of the outer adapter, which is provided with, selects a forward recess and rearward recess with raised location fit, The needle point of the inner needle tube front end it is raised coordinate with forward recess when outside the needle point of outer needle tubing front end, before the inner needle tube The needle point at end is hidden in the tube chamber of outer needle tubing in the raised cooperation with rearward recess.
Preferably, the pinpoint inclined plane inclination angle of the inner needle tube is 15 ° ~ 25 °, and the pinpoint inclined plane inclination angle of the outer needle tubing is 45°~75°。
Preferably, the pinpoint inclined plane inclination angle of the inner needle tube is 20 °, and the pinpoint inclined plane inclination angle of the outer needle tubing is 70 °.
Preferably, the external diameter of the inner needle tube is 0.55 ~ 0.58mm, and the external diameter of the outer needle tubing is 0.86 ~ 0.92mm.
Preferably, the forward recess and rearward recess are located at the opposite sides of the female groove madial wall of outer adapter respectively.
Preferably, it is connected between the forward recess and rearward recess by curved groove.
Preferably, the depth of the forward recess is not less than the depth of rearward recess.
Preferably, the female groove geomery of the outer adapter and the female groove geomery of interior adapter are identical.
Preferably, the lateral wall of the outer adapter is provided with two marks for corresponding to forward recess and rearward recess respectively.
In order to solve the above problems, another technical scheme of the invention is：A kind of double-needle tube telescopiform god as described above Preparation method through blockage puncture pin, comprises the following steps：
（1）Pin in making：Inner needle tube one end is fixed in interior adapter, the other end processes the needle point on long inclined-plane, with Pin in formation；
（2）Make outer pin：Outer needle tubing one end is fixed in outer adapter, the other end processes the needle point on short inclined-plane, with Form outer pin；
（3）Assemble inside and outside pin：The inner needle tube of interior pin is inserted in outer needle tubing from the outer adapter of outer pin, and connects interior pin Forward recess or rearward recess on the female groove madial wall of the embedded outer adapter of projection on the male tenon lateral wall of head.
Compared with prior art, present invention optimizes the structure of existing puncture needle for nerve block, achieve following beneficial to effect Fruit：（1）When puncturing, the needle point of inner needle tube is set to extend in outside the needle point of outer needle tubing by the raised cooperation with forward recess, favorably In wearing out skin manadesma；When ultrasound show inner needle tube needle point close to target nerve or peripheral vessels when, by it is raised with it is rear recessed The cooperation of groove makes the needle point of inner needle tube fall back in the tube chamber of outer needle tubing, and continuing inserting needle makes the short beveled point of outer needle tubing close to target When neural, injured nerve is not easy；（2）When nerve block technique operates, without whole inner needle tube is pulled out, it so can both avoid curing The sharp instrument injury of source property, when can avoid needing inner needle tube turning back to outer needle tubing again again, the risk of sharp instrument injury and pollution； （3）When putting pipe if desired, inner needle tube can also be pulled out, the tube chamber through outer needle tubing inserts conduit.
