When leading to midline shift, angle of inclination bigger, this puncture gate apparatus is a vertical puncturing, is difficult to ensure very much puncture ideal bit
It sets.
For another example, Fig. 3 is the puncture gate apparatus structural schematic diagram of the prior art, as shown in figure 3, being first had in piercing process pair
After the preoperative label positioning of the critical positions such as the nasion, the tragus of head row body surface, oblique coronal-plane is being carried out to position location using CT
3-D scanning after calculate puncture angle under area of computer aided, increase preoperative preparation time, increase patient and receive ray photograph
Dosage is penetrated, also needs to locating rod being fixed on operating bed in art, while fixing device is calibrated with Cross hair laser device,
It operates sufficiently complex, build is big, increases operating time, is unfavorable for disinfection recycling, and increase patient medical cost.
