Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
Embodiment 1：
A kind of puncture measurement and positioning device as shown in Figure 1, 2, it is characterised in that including measuring scale 1 and inserting needle positioning pipe 2；
The measuring scale 1 includes the ruler 11 and protractor 12 respectively with scale marker bar, wherein：
The ruler 11 opens up strip mouth 111 along its length；
The inserting needle positioning pipe 2 is provided with connecting pole 21, and the end of the connecting pole 21 forms external screw thread；
The connecting pole 21 installs nut 3 through the strip mouth 111.
Needle 4 is installed in the inserting needle positioning pipe 2.
Described protractor 12 is discoideus in 3/4.
Described protractor 12 forms a positive stop strip 121 to 90 ° by its center of circle.
Described protractor 12 is provided with hand block 122.
Actually use example：
The first step, positioning：Patient takes prone position, and on CT beds, outwardly, pin is advanced for head, and belly bolster raises about 15cm,
In puncture side right side place one piece of diameter 1.0mm Kirschner wire away from (i.e. distance A in figure) skin surface is opened at 6cm by spinous process median line
As label.
Second step, lumbar vertebrae scout scannings：To at L5/S1 interverbebral discs and intervertebral foramen carry out CT it is unenhanced, thickness, layer away from
2.5mm, it is 8.2mm that intervertebral foramen to the distance of skin surface entry point is then measured on CT images, and Kirschner wire is away from entry point
Distance is 3.2mm, while records entry point CT parameters, according to parameters obtained is calculated that inserting needle positioning pipe 2 is fixed in puncture measurement
Adjusted on the device of position to suitable position and suitable angle (i.e. included angle B in figure) and open laser labelling line, entry point is marked with marking pen.
3rd step, sterile drape：With three times at ANER DIAN sterilization skin penetrating, aseptic towel is then spread.
4th step, puncture ablation nerve root and loosen：With 2% lidocaine local anaesthesia point of puncture surrounding skin, diameter is used
2OG, length 10cm lumbar puncture needle puncture along measured inserting needle path is surveyed to intervertebral foramen direction.Confirm that needle point is located at through CT scan
In intervertebral foramen after ideal position, injection contrast agent mixed liquor 20ml (the bent peaces of iobitridol 1ml+ red sage root 5ml+ Neurotropins 12ml+
How moral 20mg), through CT again scan confirm mixed liquor be located at epidural space, above-mentioned residual mixed liquor is slowly then injected into vertebra
Between hole, while carry out nerve root and loosen.Injection pulls out pin after terminating, and site of puncture is covered with dressing.
5th step, interverbebral disc ablation：With diameter 22G, length 15cm lumbar puncture needle, along the L5/S1 waists of foregoing measurement
Intervertebral disc puncture path punctures through triangle of safety, after puncture needle enters pathological interspinal disk, confirms puncture needle needle point position through CT scan
1/3 intersection after in interverbebral disc, then slow injection concentration is 50 μ g/ml Medical ozone 15m1, carries out nucleus pulposus
Ablation, injection pull out pin after terminating, and art finishes, and lid wound is pasted with aseptic dressing.
For patient without special main complaint, peace returns ward, postoperative to advise patient lies prone position 6 hours, forbids work of leaving the bed in 24 hours
It is dynamic.
The preferred embodiment created to the utility model above is illustrated, but the utility model is created not
It is limited to described embodiment, those skilled in the art can be with the premise of without prejudice to the utility model creative spirit
