Description
Technical field
The invention belongs to epidural puncture technical field, particularly relate to one and carry level-meter type anesthesia spinal needle.
Background technology
Epidural space is positioned at human spine's middle body, is that mankind's spinal nerves runs through the important component part of protecting film up and down with vertebral body.Epidural space only has about one of about 2mm to close lacuna, and this chamber is passed due to nerve root, is a kind of safer one anesthesia system of selection reliable for effect.The method arrives epidural lacuna by epidural needle through Multi-level Organization Structure, then carries out epidural continued narcosis by entering epidural catheter under epidural needle.This anesthesia does not control by operating time, can regulate the injection of local anesthetic, reach the excellent anaesthetic effect giving patient's pain relieving according to operation technique length.But because lacuna is narrow again through multilayer tissue, when puncture needle operates often because crooked repeated localised puncture or the puncture difficulty of causing causes suffering to patient.As the alone center method of puncture that punctures, do not grasped balance by the obstacle relation organized during inserting needle and withstood inserting needle failure by vertebral body.Side is and for example adopted to enter piercing method.Due to angle grasp deviation, inserting needle difficulty causes failure or injured nerve and blood vessel to cause numbness hemorrhage, causes very large misery to patient.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the object of this invention is to provide one and carry level-meter type anesthesia spinal needle, fixing horizontal instrument is had in backshank tip designs, position is reserved when Anesthetist operates, keep the balance of level indicator, accurate point of puncture can be reached, ensure that the successful of puncture, alleviate the misery of patient.
To achieve these goals, the present invention adopts following technical scheme:
One carries level-meter type anesthesia spinal needle, comprise the epidural puncture needle body, pin hole outlet and nook closing member top, needle tail part, one end of the described epidural puncture needle body is exported with described pin hole by pin spoon shape shape connecting portion and nook closing member top is connected, characterized by further comprising level indicator entirety, the other end of the described epidural puncture needle body and described level indicator integrated connection, described level indicator entirety is connected with needle tail part, the two ends of described level indicator entirety advance with right anesthesia spinal needle respectively exits plate washer, left anesthesia spinal needle propelling is exited plate washer and is fixedly connected with, described level indicator is overall, described right anesthesia spinal needle advances and exits plate washer, described left anesthesia spinal needle advances the needle body backshank joint face exiting and formed between plate washer and match with the described epidural puncture needle body, the level indicator ball float swum in sterile liquid is provided with in described level indicator entirety.
Described anesthesia spinal needle is provided with English letter depth location sign with it, depth location indicates graduation mark, digital depth location mark.
Described right anesthesia spinal needle propelling is exited plate washer and is provided with right plate washer anti-slip veins, and described left anesthesia spinal needle propelling is exited plate washer and is provided with left plate washer anti-slip veins.
Described anesthesia spinal needle with it, one end of contiguous described level indicator entirety is provided with pin hole outlet cue mark.
Described needle tail part be provided with successively from top to bottom level indicator ball float float the next marking line and data, level indicator ball float float in upper marking line in the middle of lower marking line, level indicator ball float floating equilibrium in the middle of the next marking line and data, level indicator ball float floating equilibrium, level indicator ball float floating in upper marking line and data, level indicator ball float to float upper marking line and data.
Described level indicator entirety is connected with described needle tail part by backshank holddown groove, and the end of described needle tail part is syringe interface and nook closing member connecting portion.
The shape of described needle body backshank joint face is U-shaped mouth.
The described epidural puncture needle body, described level indicator are overall, the total length of described needle tail part is 12-13cm.
The invention has the beneficial effects as follows: be provided with fixing or rotating level indicator at needle tail part overall, make operation limit, operator limit eye-level instrument ball float, make level indicator ball float range of activity of marking line under marking line, level indicator ball float floating equilibrium centre on level indicator ball float floating equilibrium centre, convenient operation person grasps needle angle at any time, reaches the object of precise manipulation; English letter depth location sign, digital depth location mark and depth location indicate graduation mark three kinds and indicate common existence, no matter all can observe depth of needle in that angle; There is pin hole outlet cue mark, be convenient to guiding catheter approach axis.The present invention can prevent from causing anaesthetize unsuccessfully because inserting needle piercing through dura mater excessively deeply, simultaneously according to the feature that existing social development human body is generally got fat, add as 12-13cm by long for the 10cm of former anesthesia spinal needle, solve the drawback of often encountering adiposis patient clinically and should not arrive anatomical position because pin is short.Simultaneously for improving puncture success rate, reducing the case changing general anesthesia because pin is short into and have more real meaning.
