On the best oval foramen plane of scanning motion, CT measures the distance and the puncture angle of best facial point of puncture and oval foramen line, according to these two parameter adjustments angle of inclinometer position and puncture needle pusher slidably, oval foramen is accurately thrust to puncture needle in the place at the facial point of puncture of the best.
This utility model compared with prior art has many advantages and good effect:
1,, make location and puncture have more objective and accurate foundation by the CT advanced technology.
2, special-purpose headstock scaling system makes the stereotaxic localized puncture system include the CT scan system in, and makes it unified mutually with the CT scan system.
3, the stereotaxic localized puncture system makes patient's head include the CT scan system in by means of special-purpose headstock scaling system.
4, the adjustable needle insertion face of stereotaxic localized puncture system can slide on U type fixed mount as required, and rotatable its plane and the CT oval foramen plane of scanning motion coincide.
But the puncture needle guider that 5, on adjustable needle insertion face cross bar, has move left and right, comprise slidably inclinometer and rotatable, have structures such as graduated puncture needle pusher and guide pipe.On the oval foramen plane, measure the slidably angle of inclinometer position and puncture needle pusher of the distance of best facial point of puncture and oval foramen line and these two parameter adjustments of puncture angle according to CT, oval foramen is accurately thrust to puncture needle in the place at the facial point of puncture of the best.
6, the puncture point orientation wire netting is fixed in the Ipsilateral mouth outside before CT scan, and intersect with it on the CT scan plane at oval foramen place, helps to locate best facial point of puncture.
7, the navigation system various piece is conveniently detachable, can help strict sterilization, the generation of having stopped intracranial infection.
8, this navigation system can be thrust oval foramen to puncture needle like clockwork under the CT guiding, has avoided mistake to thrust the danger of other cracks of basis cranii and duct and accidental injury intracranial vessel and other cranial nerves, makes oval foramen puncture more accurately and safety.
