Description
Technical field
this utility model relates to technical field of medical instruments, especially relates to a kind of single chamber dual pathways combined spinal-epidural anesthesia one puncture needle.
Background technology
intraspinal tube combined anesthesia has become one of the first-selected anesthesia of hypogastric region, the various operation of lower limb.Intraspinal tube combined anesthesia has rapid-action, and blockage effect is good, the unrestricted advantage of anesthesia duration.The combined spinal-epidural anesthesia puncture needle that present stage uses is pin in pin, often there will be and injects lumbar anesthesia medicine rearmounted epidural catheter and be obstructed or put the ill situation of epidural catheter and happen occasionally, cause carrying out intraspinal tube combined anesthesia in use.
specifically, when using existing combined spinal-epidural anesthesia puncture needle to carry out intraspinal tube combined anesthesia, patient gets lateral position, and with the capable subarachnoid space puncture of 5# fine needle after the success of intervertebral space capable cavum epidural puncture, occur that typical case extracts nook closing member after wearing out spinal dural falling through, see that cerebrospinal fluid injects local anesthetic solution after flowing out, after extracting thin lumbar anaesthesia puncture needle, insert epidural catheter.But the rearmounted epidural catheter of lumbar anesthesia often can occur when use procedure existing combined spinal-epidural anesthesia puncture needle can not insert smoothly, causes causing great misery to patient.
Utility model content
for the unreasonable problem causing effect bad of puncture needle structure of current existing intraspinal tube combined anesthesia, this utility model key breakthrough solves a kind of combined anesthesia one puncture needle that simultaneously can be carried out epidural anesthesia and subarachnoid anesthesia by a pin puncture.
in order to realize this object, this utility model provides a kind of single chamber dual pathways combined spinal-epidural anesthesia one puncture needle, and comprise pedestal and needle tubing, described needle tubing is fixed on described pedestal, and described pedestal is provided with the passage with described needle tubing conducting; Empty to form the inner chamber making epidural catheter and/or lumbar puncture needle pass in wherein said needle tubing; Wherein, the external diameter of spinal needle is 0.45-0.55mm, and the external diameter of epidural catheter is 0.55-0.9mm.
wherein, described pedestal is provided with the passage that runs through described pedestal, and described passage end and described needle tubing conducting, the other end forms the opening for making described epidural catheter and lumbar puncture needle stretch into described needle tubing on pedestal.
wherein, described passage is greater than internal diameter that is described and needle tubing conducting one end at the internal diameter of described opening.
wherein, described pedestal is provided with the epidural catheter passage and a lumbar puncture needle passage that run through described pedestal; Wherein said epidural catheter passage and described needle tubing conducting, and the other end forms the epidural catheter opening for making epidural catheter pass on described pedestal; And described lumbar puncture needle passage also with described needle tubing conducting, and the other end forms the lumbar puncture needle opening for making lumbar puncture needle pass on described pedestal.
wherein, the coaxial of described lumbar puncture needle passage and described needle tubing is arranged, and described epidural catheter passage and described lumbar puncture needle passage have angle.
wherein, the length of described needle tubing is 8-12cm.
wherein, described needle tubing is circular, and overall diameter is 1.6-1.8mm.
wherein, described needle tubing is oval, and the major axis of described ellipse is 1.6-1.8mm, and minor axis is 1.4-1.6mm.
the beneficial effects of the utility model are: the utility model proposes a kind of single chamber dual pathways combined spinal-epidural anesthesia one puncture needle, can either carry out epidural anesthesia and can carry out Spina anesthesia again, can row lumbar anesthesia and insert epidural catheter simultaneously.Its advantage is that it first can put row lumbar anesthesia after epidural catheter, avoids the rearmounted conduit of lumbar anesthesia in the past smoothly and the situation affecting sterilization pill occurs.This utility model embodiment also proposed two kinds simultaneously.

Detailed description of the invention
below with reference to appended accompanying drawing, a preferred embodiment of the present utility model is described.
this utility model provides a kind of single chamber dual pathways combined spinal-epidural anesthesia one puncture needle, and comprise pedestal and needle tubing 1, described needle tubing 1 is fixed on described pedestal, and described pedestal is provided with the passage with the conducting of described needle tubing 1.As shown in Figure 3, empty to form the inner chamber making epidural catheter and/or lumbar puncture needle pass in wherein said needle tubing 1.As shown in figures 1 and 3, the external diameter of spinal needle is 0.45-0.55mm, and the external diameter of epidural catheter is 0.55-0.9mm.
concrete, as shown in Figure 2, this pedestal is provided with a passage, the inner chamber conducting of this passage end and needle tubing 1, and the other end has an opening 4 on pedestal.Epidural catheter 3 under this structure and lumbar puncture needle 2 are extend in pedestal by same opening 4, and stretch out from syringe needle 5 after being each passed through the interior intracavity of needle tubing 1.
as shown in Figure 2, in another embodiment of this utility model, pedestal is provided with two passages, make epidural catheter and lumbar puncture needle pass respectively, and pedestal is provided with different openings, i.e. epidural catheter opening 41 and lumbar puncture needle opening 42.
as shown in Figure 2, described pedestal is provided with the epidural catheter passage and a lumbar puncture needle passage that run through described pedestal; The epidural catheter tube chamber conducting of wherein said epidural catheter passage and described needle tubing 1, and the other end forms the epidural catheter opening 41 or 42 for making epidural catheter pass on described pedestal; And the inner chamber conducting of described lumbar puncture needle passage and described needle tubing 1, and the other end forms the lumbar puncture needle opening 42 or 41 for making lumbar puncture needle pass on described pedestal.The inner chamber conducting of described lumbar puncture needle and epidural catheter passage and described needle tubing 1, stretches out from syringe needle 5.
as shown in Figure 1 and Figure 2, the length of described needle tubing 1 is 8-12cm.Wherein said needle tubing 1 is circular, and overall diameter is 1.6-1.8mm.Wherein, described needle tubing 1 can also be oval, and the major axis of described ellipse is 1.6-1.8mm, and minor axis is 1.4-1.6mm.
when using old-fashioned combined spinal-epidural puncture bag, patient gets lateral position, and with the capable subarachnoid space puncture of 5# fine needle after the success of intervertebral space capable cavum epidural puncture, occur that typical case extracts nook closing member after wearing out spinal dural falling through, see that cerebrospinal fluid injects local anesthetic solution after flowing out, after extracting puncture needle, insert epidural catheter.Because the rearmounted conduit of lumbar anesthesia does not happen occasionally smoothly, cause conduit not insert and make combined spinal-epidural anesthesia unsuccessfully cause great misery to patient.
utility model people change a social system puncture needle for the problems referred to above, have developed new-type single chamber dual pathways combined spinal-epidural anesthesia one puncture needle, it mainly comprises 0.55 to 0.9mm epidural catheter and 0.45-0.55mm lumbar puncture needle nook closing member, this puncture needle is single chamber dual pathways, can row lumbar anesthesia and insert epidural catheter simultaneously.Its advantage is that it first can put row lumbar anesthesia after epidural catheter, puts conduit more smoothly and the situation affecting anesthesia block plane occurs after avoiding lumbar anesthesia in the past.
for person of ordinary skill in the field, along with the development of technology, this utility model design can realize by different way.Embodiment of the present utility model is not limited in embodiment described above, and can change within the scope of the claims.
