It is interior.On patient skin, first puncture needle 200 and distance of the second puncture needle 300 on patient skin are x.As shown in table 1,
It is possible 18 kinds of distance x of 18 first puncture needles 200 and second puncture needle 300 in table 1, its unit is mm.Such as：Table
The numerical value 2.35 of the third line secondary series represents in 1：Insert the pre- clamp that the second channel 22 of puncture needle is formed with first passage 21
Angle α is 2 °, and the second channel 22 is 2mm with the preset distance of first passage 21 on the upper surface of positioning table 10.Now first
Puncture needle 200 and distance 2.35mm of the second puncture needle 300 on patient skin.
The distance x of table 1 value
The subcutaneous depth that general spinal puncture pin need to insert patient is 10cm~15cm.In the present embodiment by taking 13cm as an example
Calculated, draw the distance y of first puncture needle 200 and second puncture needle 300 between subcutaneous two end.As shown in table 2,
Possible 18 kinds of distance y in table 2 between the end of second puncture needle 300 and the end of first puncture needle 200, its unit are equal
For mm.Such as：The numerical value 4.89 of the third line secondary series represents in table 2：Second channel 22 and that second puncture needle 300 is inserted
The predetermined angle α that one passage 21 is formed is 2 ° and the second channel 22 is pre- with first passage 21 on the upper surface of positioning table 10
Set a distance is 2mm, and now the distance y of second puncture needle 300 and first puncture needle 200 between subcutaneous two end is
4.89mm。
The distance y of table 2 value
From the data in table 1, it can be seen that first puncture needle 200 is to be up in the distance of skin surface with second puncture needle 300
7.76mm, i.e., the distance of two wounds are no more than 1cm, and distance is very near, and this scope is in the fiber crops of local anesthetic
In liquor-saturated scope.
From the data in table 2, it can be seen that subcutaneous, the distance y of the end of first puncture needle 200 and the end of second puncture needle 300 is most
It can be 28.69mm to be worth greatly, namely the fine setting orientation range of spinal puncture positioning auxiliary device 100 is covered using 28.69mm as radius
Circle.In addition, as shown in Table 2, there are 18 kinds apart from available, therefore, the fine setting positioning of patient can be accomplished very accurate.

On Part II 12, it is integrally formed with Part II 11.
Part I 11 and Part II 12 are made up of connecting portion 13 ' to be connected together
The effect of embodiment and effect
Spinal puncture positioning auxiliary device involved by the present embodiment, because including positioning table and channel part, channel part
In comprising supply first passage and second channel, can general so when the pin puncture of patient first offset by the target position of patient
Spinal puncture positioning auxiliary device is set on the first pin so that first puncture needle passes through first passage, then enters to patient
The positioning of row second puncture needle, by selecting suitable second channel to insert second puncture needle, due to each second channel
Bearing of trend and it is to determine with the preset distance of first passage, so as to learn that the second pin is inserted in patient's body distance
The relative position of one pin is to realize the fine setting of positioning.So, patient can enter by the way that at most contact pin is positioned at target spot twice
And operating time is shortened, reduce the pain of patient.
In addition, positioning table is hemispherical, cambered surface is smooth below, small to patient skin pressure, makes the patient feels more comfortable.
And hemispherical positioning table made of transparent material can see the part exposed of pin from below, it can also can be visually seen first and wear
Pricker and second puncture needle are moved towards inside positioning table.
Further, positioning table is divided into dismountable two parts, and the two parts can be connected by being connected together or by hinge
Connect.Before second puncture needle is inserted, because first puncture needle is already inserted into patient's body, therefore it is directly sleeved in first puncture needle
Inconvenience, using so dismountable mode so that first passage is also demountable, so as to easily quickly wear backbone
Thorn positioning auxiliary device is set in first puncture needle, facilitates doctor to operate, and then has saved operating time, improves operation effect
Rate.
Further, the cambered surface of positioning table is provided with predetermined angle corresponding to sign signal, so as to facilitate doctor to be quickly found out institute
The second channel that need to be operated.
Above-mentioned embodiment is the preferred case of the present invention, is not intended to limit protection scope of the present invention.
