Abstract
The utility model discloses an anesthesia puncture needle which comprises a needle cylinder, wherein a needle core is arranged in the needle cylinder. The anesthesia puncture needle is characterized in that a plurality of annular scale grooves are evenly formed in the outer surface of the needle cylinder in the axial direction of the needle cylinder, scales are marked on the portions, corresponding to the scale grooves, of the outer surface of the needle cylinder, and a limiting clip which can be just arranged on each scale groove in a clamped mode is arranged on the surface of the needle cylinder. By changing the position of the limiting clip, the puncturing depth is controlled and the puncture needle is prevented from being inserted too deeply. The anesthesia puncture needle is simple in structure, rapid and accurate positioning is achieved in the puncturing process, and accidents are avoided.
Description
Technical field
This utility model relates to a kind of anaesthetic puncture needle.
Background technology
Epidural anesthesia is the abbreviation of epidural space block anesthesia, refer to local anaesthetics is injected to epidural space, the retardance spinal nerve root, temporarily make its domination zone produce the anesthesia of paralysis, be mainly used in the following operation of abdominal part and abdominal part, comprise that urinary system, woman produce and lower extremity surgery.At present, the epidural anaesthetic puncture needle used clinically, by shank, needle handle and nook closing member form, the shank front end has straight port, when epidural puncture, puncture needle need to be through skin, subcutaneous tissue, supraspinal ligament, interspinal ligaments, the multilayer tissues such as ligamenta flava, finally enter epidural space, in this process, straight port often cuts off these tissues, bring very large damage to the patient, in addition, after puncturing successfully, nook closing member need be taken out, then inwardly inject anaesthetic, in taking out the nook closing member process, because puncture needle loses fixing the support and labelling, be easy to displacement, blood vessel around accidentally injuring, nerve and lymphatic vessel, even cause anaesthetic mistake notes, cause severe complication, jeopardize patient's life.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of anaesthetic puncture needle that can effectively control paracentesis depth.
For solving the problems of the technologies described above, this utility model comprises syringe, be provided with nook closing member in syringe, the outer surface that it is characterized in that described syringe axially evenly is provided with the scale groove of a plurality of annulars along it, the corresponding scale groove of syringe outer surface indicates scale, and described needle cylinder surface is provided with and can just in time be installed on the position limiting clamp on the scale groove.
After adopting said structure, by changing the position of position limiting clamp, realize the control to paracentesis depth, prevent from piercing process interting dark.This utility model is simple in structure, has realized the quick and precisely location of puncture, has avoided the generation of accident.
Described position limiting clamp comprises upper clip and the lower clamping piece with clamping part and press section, and the middle part of described upper and lower intermediate plate is hinged, and position limiting clamp is provided with the flexible member that makes upper and lower intermediate plate clamping part closure.
Described flexible member is that two ends are stuck in the curved spring steel on upper and lower intermediate plate.
The corresponding flexible member in the press section of described upper clip and lower clamping piece is provided with for the elasticity element and passes and flexible member is carried out to spacing through hole.
The accompanying drawing explanation
Below in conjunction with the drawings and the specific embodiments, this utility model is described in further detail:
Fig. 1 is structural representation of the present utility model;
The structural representation that Fig. 2 is position limiting clamp.
The specific embodiment
As depicted in figs. 1 and 2, anaesthetic puncture needle comprises syringe 1, is provided with nook closing member 2 in syringe 1, and the outer surface of syringe 1 axially evenly is provided with the scale groove 3 of a plurality of annulars along it, the corresponding scale groove 3 of syringe 1 outer surface indicates scale, and syringe 1 surface is provided with the position limiting clamp 4 that can just in time be installed on scale groove 3.In this utility model, position limiting clamp 4 comprises upper clip 41 and the lower clamping piece 42 with clamping part 5 and press section 6, the middle part of upper and lower intermediate plate 42 is hinged, position limiting clamp 4 is provided with the flexible member 43 that makes upper and lower intermediate plate 42 clamping part 5 closures, and flexible member 43 is the curved spring steel on two ends are stuck in upper and lower intermediate plate 42.For preventing that flexible member 43 in use is shifted, be provided with for elasticity element 43 and pass and flexible member 43 is carried out to spacing through hole at the corresponding flexible member 43 in the press section 6 of upper clip 41 and lower clamping piece 42, the two ends of the corresponding flexible member 43 of clamping part 5 outer surfaces of upper clip 41 and lower clamping piece 42 are respectively equipped with draw-in groove 7, prevent the two ends play of flexible member 43.
By changing the position of position limiting clamp 4, realize the control to paracentesis depth, prevent from piercing process interting dark.This utility model is simple in structure, has realized the quick and precisely location of puncture, has avoided the generation of accident.
The foregoing is only preferred embodiment of the present utility model, be not limited to this utility model.Previous embodiment has been described in detail this utility model, and for a person skilled in the art, its technical scheme that still can put down in writing aforementioned each embodiment is modified, or part technical characterictic wherein is equal to replacement.In every case within inventive concept scope of the present utility model, any modification of making, be equal to replacement, improvement etc., within all being included in protection domain of the present utility model.
