Abstract
The utility model discloses an epidural and lumbar combination puncture needle, comprising an epidural puncture needle and a lumbar anesthesia puncture needle, wherein the injection end of the epidural puncture needle is provided with a spoon-shaped elbow, and the curved surface of the spoon-shaped elbow is provided with a prepared hole coinciding with the needle tube axis of the epidural and lumbar combination puncture needle. The middle of the epidural puncture needle is glidingly provided with an epidural puncture needle core which is provided with a middle through hole, and the through hole opening of the epidural puncture needle core is corresponding to the prepared hole. The lumbar anesthesia puncture needle is glidingly connected with the epidural puncture needle core up and down in the middle through hole. As the through hole opening of the epidural puncture needle core is corresponding to the prepared hole on the curved surface of the spoon-shaped elbow of the epidural puncture needle, the lumbar anesthesia puncture needle can pass through the through hole opening and the prepared hole to enter a subarachnoid space. Thus, the smooth placing of a conduit is ensured, the penetrating accuracy rate is high, and administration is easy.
Description
Technical field
This utility model relates to the puncture instrument that a kind of surgery anesthesia is used, particularly a kind of hard waist combined puncturing needle that is used for lumbar anesthesia and epidural combined anesthesia.
Background technology
For a long time, surgery anesthesia is except general anesthesia clinically, and single lumbar anesthesia or epidural anesthesia are two kinds of intravertebral anesthesia methods commonly used.Lumbar anesthesia puncture needle and anesthesia spinal needle then are respectively to implement requisite puncture instrument in these two kinds of anesthesia.Though these two kinds of puncture instruments have his own strong points, differ from one another, and play an important role in the anesthesia process.But be subjected to the restriction of its structure, all exist some deficiency and defective.As the lumbar anesthesia puncture needle, though have easy and simple to handlely, dosage is few, anaesthetize rapid-action, advantages such as definite effect, but because its one-time puncture can only once have been annotated the anaesthetic amount of being scheduled to, prolong as operating time, the additional administration of can only puncturing once more brings unnecessary trouble and misery to the patient.Especially existing lumbar anesthesia puncture needle head is just as dagger, spinal dura mater enters after subarachnoid space annotated local anaesthetics and withdraw from passing vertebra, can on spinal dura mater, stay the next little otch that is difficult to make up for the moment, thereby cause the generation of cerebrospinal fluid seepage and postoperative headache complication., do not worry the length of operating time though but the anesthesia spinal needle successive administration is implemented continuous epidural anesthesia.But it is many to have dosage, and onset is slow, and defectives such as one-sided retardance is incomplete easily take place.Emerging clinically in recent years a kind of product that is referred to as ridge fiber crops epidural combined anesthesia puncture needle, lumbar anesthesia puncture needle and anesthesia spinal needle are used altogether, combine the part advantage of two kinds of puncture needles, but unreasonable because of its structural design, increased some new defective.Done bending process as wherein supporting combined puncturing needle head, but this combined puncturing needle head end inclined-plane is less, difficulty when inserting epidural catheter like this, guide function is little, and it is low that the lumbar anesthesia puncture needle spreads out of accuracy rate, makes conduit obstruction easy to break be difficult for administration sometimes.
The utility model content
Technical problem to be solved in the utility model provides a kind of epidural catheter when inserting, and guide function is strong, and the lumbar anesthesia puncture needle spreads out of the accuracy rate height, and the easy hard waist combined puncturing needle of administration.
For solving the problems of the technologies described above, the technical solution of the utility model is: hard waist combined puncturing needle, comprise anesthesia spinal needle and lumbar anesthesia puncture needle, described anesthesia spinal needle injection end has one spoonful of shape elbow, the flexure plane of described spoon shape elbow is provided with the preformed hole with the dead in line of described hard waist combined puncturing needle needle tubing, the centre of described anesthesia spinal needle is slidingly fitted with the epidural puncture nook closing member, perforation in the middle of described epidural puncture nook closing member is provided with, the perforation mouth of described epidural puncture nook closing member is corresponding with described preformed hole, and described lumbar anesthesia puncture needle slides up and down and is connected with the described dura mater nook closing member that punctures in the perforation in the middle of described.
Owing to adopted technique scheme, hard waist combined puncturing needle, comprise anesthesia spinal needle and lumbar anesthesia puncture needle, described anesthesia spinal needle injection end has one spoonful of shape elbow, the flexure plane of described spoon shape elbow is provided with the preformed hole with the dead in line of described hard waist combined puncturing needle needle tubing, the centre of described anesthesia spinal needle is slidingly fitted with the epidural puncture nook closing member, perforation in the middle of described epidural puncture nook closing member is provided with, the perforation mouth of described epidural puncture nook closing member is corresponding with described preformed hole, and described lumbar anesthesia puncture needle slides up and down and is connected with the described dura mater nook closing member that punctures in the perforation in the middle of described; Because the perforation mouth of the epidural puncture nook closing member in this utility model is corresponding with anesthesia spinal needle preformed hole on the flexure plane of spoon shape elbow, from then on the lumbar anesthesia puncture needle can bore a hole mouthful and preformed hole passes through, enter subarachnoid space, can guarantee that like this conduit inserts smoothly, can make the lumbar anesthesia puncture needle pass the accuracy rate height again, easily administration.
