Step 5): after bevel protractor combination unit fixes, the right-angle side contacted with I type bevel protractor due to II type bevel protractor has the effect of pointer, therefore when II type bevel protractor rotates along I type bevel protractor scale surface, angle indicated by the right-angle side that II type bevel protractor contacts with I type bevel protractor 21, namely loses the puncture angle of shape position;
Step 6): after the right-angle side that II type bevel protractor contacts with I type bevel protractor indicates and loses shape position puncture angle, fixing II type bevel protractor is motionless, continues to rotate II type bevel protractor pointer, now, angle on II type bevel protractor microdactylia pin instruction II type bevel protractor, i.e. the puncture angle of horizontal position;
Step 7): keep II type bevel protractor and pointer position motionless, puncture needle enters after skin through point of puncture, relies on the guiding function of thick pointer of pointer, keeps puncture needle and thick pointer horizontal direction inserting needle, namely realizes the accurate puncture of 3 D stereo;
Step 8): puncture successfully, can orientation tool be taken away.
The beneficial effects of the utility model are: the Needle localization instrument that this 3 D stereo takes measurement of an angle share the Minimally Invasive Surgery in row puncture for treating, with low cost, convenient and practical, measure puncture angle simultaneously provide convenience for losing shape position and horizontal position in Minimally Invasive Surgery, improve puncture accuracy, reduce operation risk.
