Center, and the datum mark M of arrangement is measured at 4 center location of sagittal plain Angle protractor（Practical at center location is exactly patient
Point of puncture N above body epidermis）Between need the distance of setting, that is, measure corresponding hinged shaft 13 right over lesion centrum target spot 62
Center, point of puncture N on patient's epidermal location above identified datum mark M to patient's body epidermis distance；
In operation, first, centrum 6 is had an X-rayed by mobile C-arm X-ray machine, the position of patient is adjusted, finds lesion centrum spine
The datum mark M of 61 surface patient's epidermis of prominent central point, and the lesion centrum spinous process central point 61 and lesion centrum spinous process center
What the line of the datum mark M of 61 surface patient's epidermises of point was constituted perpendicular to bolt angle locater transverse presentation scale 1 and vertical position scale 2
Plane.On this basis, at 61 surface patient's epidermis of lesion centrum spinous process central point on patient's body on find benchmark
Point M and the body of the datum mark M longitudinally supracutaneous line of corresponding patient's body above each 61 line of spinous process central point is crossed, it will
The crosspoint of the transverse presentation scale 1 of bolt angle locater and vertical position scale 2 is correspondingly placed at right over the lesion centrum spinous process of patient
At the positions datum mark M, and to be arranged in the body of datum mark M longitudinally right above each 61 line of spinous process central point for vertical position scale 2
It answers on the supracutaneous line of patient's body.
In operation, the offset distance L and three-dimensional viewpoin of the puncture needle casing 5 of puncture locator are then adjusted and fixed（Pitching
Angle [alpha] and deflection angle β）.
In operation, finally under the irradiation of centrum X-ray, puncture needle is inserted by lesion centrum target spot by puncture needle casing 5
62 positions, and remove puncture locator after the completion of puncturing.
The above specific technical solution is only to illustrate the utility model, rather than its limitations.Although with reference to above-mentioned specific skill
The utility model is described in detail in art scheme, it will be understood by those of ordinary skill in the art that：It still can be right
Above-mentioned specific technical solution is modified or equivalent replacement of some of the technical features；And these are changed or replace
