specific Embodiment approach

[0044] Taking the lumbar topology optimization artificial vertebra design as an example, the specific implementation method is as follows:

[0045]Step 1: Reconstruct the geometric model of the patient's spinal vertebral body segment. The CT data of the patient's spine region were collected, and all fixed vertebral body segments of the patient (such as figure 1 As shown, the fixed segment is the L1-L5 segment) three-dimensional model;

[0046] Step 2: Internal fixation system design. According to the preoperative planning, the internal fixation system was designed in the three-dimensional mechanical design software Solidworks (Version 2014, Dasssault Systemes S.A, France). The fixation system consisted of internal fixation rods and pedicle screws, and the diameter of the fixation rods was 5.5 mm. The pedicle screw is 6mm;

[0047] Step 3: Initial model design of the artificial vertebral body. The design of the artificial vertebral body is determined according to the height...

Abstract

The invention discloses a topology-optimized artificial vertebral body and a design method thereof. The artificial vertebral body includes an open-hole topological thin-wall structure and a porous structure placed in the open-hole topological thin-wall structure, wherein the topological thin-wall structure is based on multiple A topology optimization method under the mechanical environment of motion gait is used to design the lightweight prosthesis. On the basis of meeting the strength requirements of the prosthesis in different motion states, a porous structure is added to meet the requirements of bone ingrowth, so as to realize the prosthesis. The later biological fixation ensures good stability. The topology-optimized artificial vertebral body introduced in the present invention can ensure the immediate stability and mid- and long-term stability of the artificial vertebral body after implantation through the organic combination of the open-hole topology thin-walled structure and the porous structure, and is beneficial to the recovery of the patient's spinal function. Improved quality of life.

Description

technical field [0001] The invention belongs to the field of prosthesis design and manufacture, and in particular relates to a topology-optimized artificial vertebral body and a design method thereof. Background technique [0002] The spine bears the skull on the top and connects the hip bone on the bottom. It is an important part of the skeletal system of the human body. It plays physiological functions such as maintaining the body, protecting the spinal cord, and performing sports. Because spinal tumors, tuberculosis, and severe fractures often cause spinal destruction, which may lead to spinal nerve damage, vertebral body resection and reconstruction are required. [0003] Currently, there are three commonly used methods for vertebral body reconstruction: bone graft reconstruction, including autologous bone and allogeneic bone graft; titanium mesh reconstruction; and artificial vertebral body reconstruction. For autologous bone transplantation, it will cause secondary in...
