in canalis spinalis, combined anesthesia has become one of first-selected anesthesia of hypogastric region, the various operations of lower limb.The interior combined anesthesia of canalis spinalis has rapid-action, and blockage effect is good, the unrestricted advantage of anesthesia duration.The combined spinal-epidural anesthesia puncture needle that present stage is used is pin in pin, often there will be the rearmounted epidural catheter of injection lumbar anesthesia medicine to be obstructed or to put the ill situation of epidural catheter happen occasionally, cause carrying out combined anesthesia in canalis spinalis in use.Specifically, in the time using existing combined spinal-epidural anesthesia puncture needle to carry out in canalis spinalis combined anesthesia, patient gets lateral position, and puncture by the capable subarachnoid space of 5# fine needle after the capable cavum epidural puncture success of intervertebral space, occur extracting nook closing member after typical case wears out spinal dural falling through, see after cerebrospinal fluid flows out and inject local anesthetic solution, insert epidural catheter after extracting thin lumbar anaesthesia puncture needle.But lumbar anesthesia often can occur existing combined spinal-epidural anesthesia puncture needle in the time of use procedure, rearmounted epidural catheter can not be inserted smoothly, causes causing great misery to patient.
Utility model content
for the unreasonable bad problem of effect that causes of puncture needle structure of combined anesthesia in current existing canalis spinalis, this utility model key breakthrough has solved that a kind of structure is more reasonable combines to improve that anaesthetic effect is better, the two-chamber combined spinal-epidural anesthesia one puncture needle of more convenient operation in canalis spinalis.
in order to realize this object, this utility model provides a kind of two-chamber combined spinal-epidural anesthesia one puncture needle, comprise puncture needle body, described puncture needle body comprises separate epidural catheter tube chamber 1 and lumbar puncture needle pin chamber 2, the body in described epidural catheter tube chamber 1 and lumbar puncture needle pin chamber 2 is arranged side by side, and one end forms the syringe needle being arranged side by side, and the other end is separated from each other; Wherein, one end of described epidural catheter tube chamber 1 is provided with epidural catheter outlet 11, and the other end is provided with epidural catheter entrance 12; The one end in described lumbar puncture needle pin chamber 2 is provided with lumbar anaesthesia puncture needle outlet 21, and the other end is provided with lumbar anaesthesia puncture needle entrance 22.
wherein, described epidural catheter tube chamber 1 is one-body molded to form puncture needle body with lumbar puncture needle pin chamber 2, or epidural catheter tube chamber 1 is fixed together side by side and forms puncture needle body with lumbar puncture needle pin chamber 2.
wherein, the internal diameter of described epidural catheter tube chamber 1 is 0.6-0.9mm; And the internal diameter in described lumbar puncture needle pin chamber 2 is 0.55-0.7mm.
wherein, the cross section of described puncture needle body is the circle of diameter 1.6 to 2.1mm; Or the cross section of described puncture needle is oval, and described oval-shaped major axis is 1.6--2.1mm, and minor axis is 1.4-1.8mm.
wherein, the length of described puncture needle body is 8-12cm.
wherein, described two-chamber combined spinal-epidural anesthesia one puncture needle also comprise intert be arranged at the lumbar anesthesia fine needle that described lumbar puncture needle pin chamber 2 interior diameters are 0.45-0.55mm, described lumbar anesthesia fine needle is provided with nook closing member.
wherein, the described other end is provided with the needle stand 3 being wrapped in outside described epidural catheter tube chamber 1 and lumbar puncture needle pin chamber 2.
the beneficial effects of the utility model are: the utility model proposes a kind of two-chamber combined spinal-epidural anesthesia one puncture needle, have epidural catheter tube chamber 1 and lumbar puncture needle pin chamber 2 simultaneously, can carry out respectively lumbar anesthesia and insert epidural catheter.Therefore this utility model existing puncture needle of comparing, carry out that epidural catheter is inserted and to carry out lumbar anesthesia be separate simultaneously, this utility model great advantage is first to insert row lumbar anesthesia after epidural catheter, the problem having some setbacks insert epidural catheter again after lumbar anesthesia time be can avoid, impact anesthesia, retardance plane prevented.
