Embodiment 1

[0041] Such as Figure 1-5 As shown, the personalized 3D printed spinal reconstruction device includes a vertebral body support 1 .

[0042] The vertebral body supporter 1 is a sleeve shape with a rectangular cross section, and it includes a front wall 11, a rear wall 12, a left wall 13, and a right wall 14, and each wall includes a quadrilateral frame and a grid set in the frame . The upper and lower end surfaces of the vertebral body supporter 1 are in close contact with the surfaces of the upper and lower vertebrae adjacent to the target vertebra.

[0043]Preferably, the front wall 11 of the vertebral body support 1 has an outwardly protruding arc, and the arc is consistent with the outward curvature of the target vertebra.

[0044] Preferably, the grid of the front wall 11 of the vertebral body supporter 1 is a grid with triangular hollow holes and rectangular hollow holes; the grid of the rear wall 12 is a grid of triangular hollow holes; the grid of the left wall 13 is...

Abstract

The invention discloses a customized 3D printing spinal column reconstruction apparatus which comprises a spinal column supporter. The spinal column has a sleeve shape and comprises a front wall, a rear wall, a left wall and a right wall, wherein each wall comprises a quadrilateral framework and a grid arranged inside the framework. The method for preparing the customized 3D printing spinal column reconstruction apparatus comprises the steps of S01 obtaining medical image data; S02 obtaining a spinal column iconography parameter; S03 establishing a three-dimensional model of a spinal column supporter in the type to be selected; S04 selecting the type of a spinal column supporter for operation; and S05 manufacturing a customized 3D printing spinal column reconstruction apparatus. The apparatus is used for various spinal column or intervertebral disk resection and fusion operation among the spinal columns. As a spinal column supporter, the apparatus is adapted to both the upper and the lower bone surface of the spinal column completely to build a good stability; the physiological curvature of the spinal column, the intervertebral height and the spinal column dissect structure can be reconstructed; the characteristics of vertebra biomechanics can be copied; and the patient's life quality can be improved.

Description

technical field [0001] The invention relates to the field of spinal surgery medical instruments, in particular to a personalized 3D printing spinal reconstruction device and a preparation method thereof for various types of vertebral bodies, intervertebral disc resection and intervertebral body fusion operations. Background technique [0002] For the treatment of spinal degeneration, spinal tumors, spinal tuberculosis and spinal trauma, especially in the treatment of cervical diseases, subtotal corpectomy and total corpectomy have been widely used. The key to spinal surgery is decompression , bone grafting and fusion, and good bone graft fusion can rebuild the physiological curvature of the spine and intervertebral height, and maintain the stability of the cervical spine. [0003] In the early industry, autologous ilium or fibula bone graft was used as the support of the vertebral body to reconstruct the spine structure. Although it has good biological characteristics of bon...
