Connecting portion 13 includes first axle component 13a, second hinge component 13b and pin 13c.
First axle component 13a is in cylinder, and first through hole is provided with axial centerline.First axle component 13aIt is fixed on Part I 11, is integrally formed with Part I 11.
Second hinge component 13a is in cylinder, and the second through hole is provided with axial centerline.Second hinge component 13aIt is fixed on Part II 11, is integrally formed with Part II 12.
Pin 13c runs through first through hole and the second through hole, so that Part I 11 and Part II 12 pass through connectionPortion 13 forms hinge connection.
Channel part 20 is arranged in positioning table 10, includes first passage 21 and multigroup second channel 22.
First passage 21 is passed through for first puncture needle, and first passage 21 is arranged on the central axis of positioning table.Due to ridgePost puncture needle generally use 18G (No. 12) puncture needle, a diameter of 1.2mm of puncture needle of this type, therefore to be adapted with it,The internal diameter of first passage 21 is arranged to 1.5mm in the present embodiment.
Second channel 22 passes through for second puncture needle.In the present embodiment, channel part 20 includes 6 groups of second channels 22.InstituteThe internal diameter for having second channel 22 is 1.5mm.
Direction of the second channel 22 from the upper surface of positioning table 10 to lower end away from first passage 21 extends, so that withPredetermined angle α is formed between first passage 21.
Fig. 4 is sectional views of the Fig. 2 in A-A ' sections；Fig. 5 is sectional views of the Fig. 2 in B-B ' sections；And Fig. 6 is that Fig. 2 existsThe sectional view in C-C ' sections.
As shown in figures 4-6,6 groups of second channels 22 are respectively：
As shown in right part in Fig. 6, the predetermined angle between first group of second channel 22 and first passage 21 is 0 °.
As shown in right part in Fig. 4, the predetermined angle between second group of second channel 22 and first passage 21 is 2 °.
As shown in right part in Fig. 5, the 3rd group of predetermined angle between second channel 22 and first passage 21 is 4 °.
As shown in left part in Fig. 6, the 4th group of predetermined angle between second channel 22 and first passage 21 is 6 °.
As shown in left part in Fig. 5, the 5th group of predetermined angle between second channel 22 and first passage 21 is 8 °.
As shown in left part in Fig. 4, the 6th group of predetermined angle between second channel 22 and first passage 21 is 10 °.
Above-mentioned every group of second channel 22 includes 3 second channels 22.As shown in Fig. 23 second channels 22 are positioned at fixedOn the same straight line of position platform 10.As shown in Fig. 2 the spacing between the second channel adjacent with group second channel 22 is 2mm, such asShown in Fig. 4, it is respectively with the preset distance between the upper port of 3 second channels 22 and the upper port of first passage 21 of group2mm, 4mm and 6mm.
As shown in figure 1, the sign for illustrating the predetermined angle in corresponding position is provided with the side of positioning table 1010a。
Fig. 7 is backbone Needle localization servicing unit use state diagram in embodiments of the invention one.
As shown in fig. 7, first puncture needle 200 is inserted in first passage 21, in second puncture needle insertion second channel 22.It is fixedThe skin of patient is close in the lower surface of position platform 10, on the lower surface of positioning table 10, between first passage 21 and second channel 22Distance x.As shown in table 1,18 kinds of distance x in table 1 between 18 second channels 22 and first passage 21, its unit aremm.Such as：The numerical value 2.35 of the third line secondary series represents in table 1：The pre- clamp that this second channel 22 is formed with first passage 21Angle 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.This secondPassage 22 is 2.35mm with the distance x of first passage 21 on the lower surface of positioning table 10.
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 exampleCalculated, 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 equalFor 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 insertedOne passage 21 formed predetermined angle α be 2 °, and the second channel 22 on the upper surface of positioning table 10 with first passage 21Preset distance is 2mm, and now the distance y of second puncture needle 300 and first puncture needle 200 between subcutaneous two end is4.89mm。
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 3007.76mm, 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 anestheticIn 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 mostIt 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 radiusCircle.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.

The effect of embodiment and effect
Spinal puncture positioning auxiliary device involved by the present embodiment, because including positioning table and channel part, channel partIn comprising supply first passage and second channel, can general so when the pin puncture of patient first offset by the target position of patientSpinal puncture positioning auxiliary device is set on the first pin so that first puncture needle passes through first passage, then enters to patientThe positioning of row second puncture needle, by selecting suitable second channel to insert second puncture needle, due to each second channelBearing 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 distanceThe 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 twiceAnd operating time is shortened, reduce the pain of patient.
Further, positioning table is divided into dismountable two parts, and the two parts can be connected by being connected together or by hingeConnect.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 needleInconvenience, using so dismountable mode so that first passage is also demountable, so as to easily quickly wear backboneThorn positioning auxiliary device is set in first puncture needle, facilitates doctor to operate, and then has saved operating time, improves operation effectRate.
Further, positioning table is made up of transparent material, can so can be visually seen first puncture needle and second puncture needleTrend.
Further, the side of positioning table is provided with predetermined angle corresponding to sign signal, so as to facilitate doctor to be quickly found out instituteThe 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.
