Problems solved by technology

The ideal slotting position should be at the transition between the lamina and the lateral mass, but because of the anatomical variation among individuals, this increases the difficulty of the operation

Embodiment 1

[0034] The software used in this embodiment includes Mimics and 3-matic, and of course other software can also be used in other embodiments. Such as figure 1 As shown, the manufacturing method of the 3D printing guide plate for cervical single-door surgery disclosed by the present invention comprises the following steps:

[0035] a. Data collection: The patient underwent a thin-section CT scan of the neck to obtain the original imaging data of the patient;

[0036] b. Cervical spine model reconstruction:

[0037] b1: Obtain the DICOM file storing the original data of the patient's cervical spine imaging;

[0038] b2: Import the DICOM file into MIMICS software to reconstruct the 3D model of the cervical spine;

[0039] c. Guide plate model establishment:

[0040] c1. save the cervical vertebra 3D model in step b as an STL format file;

[0041] c2. Open the STL format file in step c1 in 3-Matic software, such as figure 2 As shown, the spinous process 11 of cervical verteb...

Embodiment 2

[0053] Such as Figure 10 As shown, the difference between this embodiment and embodiment 1 is that the following operations are performed before step d: use 3-Matic software to create two fixing nails 7, and assemble the two fixing nails 7 on both sides of the notch 10 respectively, so that the fixing The nail 7 is located between the grinding and drilling operation channel 8 and the gap 10, the direction of the fixing nail 7 is parallel to the gap 10, and perpendicular to the back surface of the lamina; then Boolean operation is performed on the guide plate model obtained in step c6 and the fixing nail 7 to obtain The guide plate model of the drilling operation channel 8 and the fixed nail channel 9; finally, the three-dimensional data of the guide plate model with the grinding and drilling operation channel 8 and the fixed nail channel 9 are imported into the 3D printer to make a solid guide plate.

Embodiment 3

[0056] The software used in this embodiment includes Mimics and 3-matic, and of course other software can also be used in other embodiments. Such as figure 1 As shown, the manufacturing method of the 3D printing guide plate for cervical single-door surgery disclosed by the present invention comprises the following steps:

[0057] a. Data collection: The patient underwent a thin-section CT scan of the neck to obtain the original imaging data of the patient;

[0058] b. Cervical spine model reconstruction:

[0059] b1: Obtain the DICOM file storing the original data of the patient's cervical spine imaging;

[0060] b2: Import the DICOM file into MIMICS software to reconstruct the 3D model of the cervical spine;

[0061] c. Guide plate model establishment:

[0062] c1. save the cervical vertebra 3D model in step b as an STL format file;

[0063] c2. Open the STL format file in step c1 in 3-Matic software, such as figure 2 As shown, the spinous process 11 of cervical verteb...

Abstract

The invention relates to a method for manufacturing a 3D printing guide plate for a single-open-door cervical vertebra surgery. The method comprises the following steps: reestablishing a cervical vertebra model of a patient according to original cervical vertebra image data of different patients; simulating to determine a position needing to be slotted and a size range of a guide plate on the cervical vertebra model; establishing a three-dimensional model of the guide plate through computer software; and finally, importing three-dimensional data of the guide plate into a 3D printer to manufacture the guide plate. By using the method, a doctor can determine the slotted position according to the cervical vertebra conditions of different patients before the surgery, and can quickly design and prepare the guide plate for auxiliary operation in the single-open-door cervical vertebra surgery according to the collected original image data. On one hand, the position determination is accurate, an optimal pressure reduction effect can be achieved, and the occurrence of complications is reduced. On the other hand, the difficulty of the surgery is reduced, the operation errors of the surgery are reduced, the quality of the surgery is improved, and the learning curve of a young surgeon can be shortened.

Description

technical field [0001] The invention relates to a manufacturing method of a medical tool, in particular to a manufacturing method of a 3D printing guide plate for cervical single-door surgery. Background technique [0002] Cervical single-door laminoplasty is abbreviated as single-door surgery. Posterior cervical single-door surgery is currently a common method for the surgical treatment of multi-stage cervical disc herniation, cervical spinal stenosis, and ossification of the posterior longitudinal ligament. The choice of slotting positions on the portal side and the portal axis side in posterior cervical single-door surgery is very important for the successful implementation of the operation. If the position of the slot on the opening side is too close to the midline, it may lead to unsatisfactory opening effect and insufficient expansion of the spinal canal, which will affect the effect of surgical decompression; The vertebral artery causes massive hemorrhage. In additio...
