Description

Cervical vertebra 3D prints navigation template
Technical Field
The utility model relates to the technical field of medical instruments, in particular to a 3D printing navigation template for cervical vertebra.
Background
The posterior cervical spine transpedicular screw placement operation is still a complex high-risk operation. The main stream nail placing method is still the auxiliary free-hand empirical nail placing in the C-arm operation, because the upper cervical vertebral canal is narrow, the vertebral pedicle is thin (the diameter is about 3-4mm), the proximal vertebral artery and spinal nerve, especially the vertebral artery malformation high-span patient, only one-time nail placing is needed, the empirical nail placing is easy to damage the nerve vessel, the four limbs sensory and movement disorder, paralysis, cerebral infarction and even life threatening conditions occur, the statistical analysis experience is very rich, the success rate of free-hand nail placing of the spinal surgeon is 84% -86%, the success rate of nail placing is effectively improved, and the incidence rate of operation complications is urgently needed to be solved by the spinal surgeon at present.
SUMMERY OF THE UTILITY MODEL
The technical problem to be solved by the utility model is to overcome the defects of the technology and provide a cervical vertebra 3D printing navigation template.
In order to solve the technical problem, the technical scheme provided by the utility model 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.
Compared with the prior art, the utility model 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.

Fig. 1 is a schematic structural diagram of a 3D printing navigation template for cervical vertebrae according to the present invention.
As shown in the figure: 1. nail placing channels A and 2, nail placing channels B and 3, printing channels a and 4, printing channels B and 5 and cervical vertebra model
Detailed Description
The following describes a 3D printing navigation template for cervical vertebrae according to the present invention in detail with reference to fig. 1.
With reference to fig. 1, a 3D printing navigation template for cervical vertebrae includes a nail placing channel a1, a nail placing channel B2, a printing channel a3, a printing channel B4 and a cervical vertebrae model 5; the nail placing channel A1, the nail placing channel B2, the printing channel A3 and the printing channel B4 are all hollow cylinders and are embedded in the cervical vertebra model 5, the fixing of screws on the cervical vertebra model is facilitated, the nail placing channel A1 and the printing channel A3 are arranged in parallel, the nail placing channel B2 and the printing channel B4 are arranged in parallel, angle direction guiding reference is improved for opening a way of a vertebral pedicle and placing nails, the printing channel A3 and the printing channel B4 are in cross connection, the stability of a navigation template can be improved, the surgical visual field is obviously improved, angle guiding reference is provided for the needle inserting direction, and the method is more accurate and practical.
The diameters of the nail placing channel A1 and the nail placing channel B2 are equal, the diameters of the printing channel A3 and the printing channel B4 are equal, and the diameter of the nail placing channel A1 is larger than the diameter of the printing channel A3.
The length of the nail placing channel A1 is equal to that of the nail placing channel B2, the length of the printing channel A3 is equal to that of the printing channel B4, and the length of the nail placing channel A1 is smaller than that of the printing channel A3, so that the back neck muscle can be effectively prevented from being shielded.
The cervical vertebra model 5 conforms to the shape of a human cervical vertebra.
In the process of manufacturing the template, at least the following steps are included:
(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;
