In order to solve the technical problem, the technical scheme provided by the invention is a cervical vertebra 3D printing navigation template, which comprises a nail placing channel A, a nail placing channel B, a printing channel a, a printing channel B and a cervical vertebra model; the nail placing channel A, the nail placing channel B, the printing channel a and the printing channel B are all hollow cylinders and are embedded in the cervical vertebra model, the nail placing channel A and the printing channel a are arranged in parallel, the nail placing channel B and the printing channel B are arranged in parallel, and the printing channel a and the printing channel B are in cross connection.
As a modification, the diameter of the nail placing channel A is equal to that of the nail placing channel B, the diameter of the printing channel a is equal to that of the printing channel B, and the diameter of the nail placing channel A is larger than that of the printing channel a.
As a modification, the lengths of the nail placing channel A and the nail placing channel B are equal, the lengths of the printing channel a and the printing channel B are equal, and the length of the nail placing channel A is smaller than that of the printing channel a.
As an improvement, the cervical vertebra model is consistent with the shape of the human cervical vertebra.
The invention also provides a technical scheme that: the method for manufacturing the cervical vertebra 3D printing navigation template at least comprises the following steps:
(1) collecting CT data of cervical vertebra of a patient before operation and designing length, diameter, needle insertion point and angle parameters of a screw;
(2) and (3) importing the CT data and the parameters in the step (1) into the Mimics software and making.
Compared with the prior art, the invention has the advantages that:
the nail placing channel A, the nail placing channel B, the printing channel a and the printing channel B are all hollow cylinders, so that screws can be fixed on the cervical vertebra model conveniently;
the nail placing channel A and the printing channel a are arranged in parallel, the nail placing channel B and the printing channel B are arranged in parallel to form a pedicle open circuit, and the nail placing direction guide reference is improved;
the printing channel a and the printing channel b are connected in a crossed manner, so that the stability of the navigation template is obviously improved, the operation visual field is obviously improved, and an angle guide reference is provided for the needle inserting direction, so that the method is more accurate and practical.
