Abstract
The utility model relates to a double-channel puncture anesthesia needle. The utility model is composed of a needle body (3) and two needle seats (1), (2), wherein, two independent needle chambers (4), (6) which are mutually parallel are arranged inside the needle body (3). Each needle chamber and respective jacks (5), (7) for the needle seats respectively form independent channels, one channel is a straight pipe channel, and the other channel is a channel with a large straight pipe part and a small curved pipe part. The anesthetic needle is used for anesthesia. An epidural indwelling pipe is operated, then, lumbar anesthesia is operated, and the anesthesia can be completed once. The utility model gives full play to the advantages of a lumbar anesthesia method and an epidural anesthesia method, and the utility model overcomes respective defects of the lumbar anesthesia method and the epidural anesthesia method.
Description
This utility model belongs to a kind of operation medical apparatus and instruments, particularly relates to the anesthesia surgery puncture needle.
In the operation of general long period, need epidural anesthesia and lumbar anesthesia to unite use, can give full play to the characteristics that the lumbar anesthesia analgesic is reliable rapidly, success rate is high, dosage is little, toxicity is low, and overcome lumbar anesthesia limited shortcoming action time.Past epidural anesthesia and lumbar anesthesia often will carry out respectively, increase patient's misery and surgical wound surface.Adopt the dorsal pore method in recent years, owing to use same passage, it is liquor-saturated therefore must to do lumbar anesthesia earlier, and then inserts epidural catheter, otherwise not all right.And in putting the pipe process,, cause that easily blood circulation suppresses because the long level of anesthesia that easily causes of time is difficult to control, the risk factor of anesthesia is increased, and associating shadow film is anaesthetized failure outward.
The purpose of this utility model provides a kind of dual pathways puncture anesthetic needle that makes epidural anesthesia and lumbar anesthesia can unite use, and it is a special-purpose anesthetic needle rational in infrastructure, easy to use.
The purpose of this utility model realizes by the following technical solutions: two-way independent pin chamber parallel to each other is set in the puncture needle body of pin, and independently passage is formed with needle stand jack separately respectively in each pin chamber.Wherein pin chamber and needle stand jack are formed the straight tube passage, and its needle tip is side (tiltedly) opening; Another pin chamber major part is the straight tube passage, is the camber tube passage in nearly needle stand (or in needle stand) part.
This utility model is made up of puncture needle body and needle stand, comprises two parallel straight tube pin chambeies in needle body, and the outlet in a pin chamber is respectively arranged is pin hole to top ends on each pin chamber of needle body.Insert in the needle stand needle body lower end, and its needle body is divided into two-way, and one tunnel and straight-through needle stand forms independent straight tube pin, and the pin chamber of this road needle body and the nook closing member jack of needle stand form the straight tube passage, and when doing anesthesia, this paths can be used as the tube passage of putting of dura mater anesthesia; Another road is inserted in the bypass needle stand, forms the bypass pin, and needle body is part camber tubulose, and the pin chamber of this road needle body and the nook closing member jack of needle stand form part camber passage, and this paths can be done lumbar anesthesia in use.
Pin hole is not blocked when puncturing in order to guarantee to do, and can be used with nook closing member when using this utility model anesthetic needle.Needle stand can be two independently, the individuality that also can unite two into one, and promptly a seat has two nook closing member jacks.
The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment:
Accompanying drawing is the vertical section structure sketch map of this utility model embodiment;
In the drawings, dual pathways puncture anesthetic needle of the present utility model comprises needle stand and needle body, and needle stand is made up of straight-through needle stand 1 and bypass needle stand 2.Two independent pin chambeies parallel to each other are arranged in needle body 3 inside, be (straight tube pin chamber) 4, epidural anesthesia pin chamber and spinal needle chamber (bypass pin chamber) 6, the top has the external pore of dura mater (straight tube pin hole) 8 and lumbar anesthesia pin hole (bypass pin hole) 9 respectively thereon, hole 8 is oblique or side opening, and promptly opening is to the side; 5 and 7 is respectively epidural needle core print seat jack and spinal needle core print seat jack.
Adopt this utility model dual pathways puncture anesthetic needle to do anesthesia surgery, can do the external pipe of dura mater earlier, after do lumbar anesthesia and once finish anesthesia.Adopt Wicresoft's subarachnoid space puncture needle can obviously reduce the incidence rate of having a headache behind the lumbar anesthesia.Epidural and lumbar anesthesia are united use can give full play to the characteristics that the lumbar anesthesia analgesic is reliable rapidly, success rate is high, dosage is little, toxicity is low.Associating dura mater external enwergy overcomes lumbar anesthesia limited shortcoming action time, overcomes the not golden shortcoming of epidural autoretardation simultaneously.Promptly use this utility model can give full play to the advantage of lumbar anesthesia and two kinds of methods of epidural anesthesia, overcome its shortcoming separately.This utility model is applicable to the emergency operation of middle hypogastric region, lower limb and the anesthesia of unrestricted operation of time.
This utility model dual pathways puncture anesthetic needle except that needle body must be make with metal, needle stand available metal or medical macromolecular materials are made.
Claims (5)
1, a kind of dual pathways puncture anesthetic needle, form by needle body and needle stand, it is characterized in that in puncture needle body (3) two-way independent pin chamber (4) and (6) parallel to each other being set, pin chamber (4) and pin chamber (6) form independently passage with needle stand jack (5) and (7) respectively.
2, the dual pathways according to claim 1 puncture anesthetic needle is characterized in that needle stand is made up of straight-through needle stand (1) and bypass needle stand (2).
3, dual pathways puncture anesthetic needle according to claim 1 and 2 is characterized in that needle body (3) is divided into two-way, and one tunnel and straight-through needle stand (1) forms independent straight tube pin, and another road and bypass needle stand (2) form the bypass pin.
4, dual pathways puncture anesthetic needle according to claim 3 is characterized in that straight tube pin hole (8) is oblique or diagonal cut joint.
5, dual pathways puncture anesthetic needle according to claim 3 is characterized in that the needle body (3) of bypass pin is part camber tubulose, and the pin chamber (6) of this road needle body forms part camber passage with the nook closing member jack of needle stand (2).
