Embodiment Construction

[0032] Next, the technical solutions in the embodiments of the present invention will be described in connection with the drawings of the embodiments of the present invention, and it is understood that the described embodiments are merely the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained without creative labor are not made in the premise of creative labor.

[0033] like figure 1 , In one embodiment, there is provided a method of constructing a skeleton model, the bone model construction method includes the following steps:

[0034] Step 102, according to the scan data of the patient's bone geometry modeling, to give the geometric model, each set of different materials corresponding portions of the geometric model physical parameters to obtain the original model.

[0035] Wherein the patient's bone means the bone site in need of treatment, such as cervical vertebrae, lumbar vertebr...

Abstract

The embodiment of the invention discloses a method for manufacturing an interbody fusion cage, which comprises the steps that an input device inputs patient vertebra scanning data, patient data and a treatment scheme to a processor device, and the processor device establishes an optimization problem and solves the optimization problem according to the patient vertebra scanning data, the patient data and the treatment scheme to obtain an optimal topological structure; the processor device establishes an interbody fusion cage finite element model according to the optimal topological structure, and transmits the interbody fusion cage finite element model to a display device for display; the processor device sends a manufacturing instruction to a manufacturing device after receiving a message that a clinician confirms that the interbody fusion cage finite element model is available, and the manufacturing device manufactures the interbody fusion cage based on the interbody fusion cage finite element model after receiving the manufacturing instruction. The problem that in a traditional scheme, standard bone medical instruments are not matched with the physiological and pathological conditions of a patient is solved, and the treatment effect of the interbody fusion cage is improved. In addition, the invention further discloses a system for manufacturing an interbody fusion cage.

Description

Technical field [0001] Technical Field The present invention relates to medical instruments, in particular, it relates to an intervertebral fusion device manufacturing method and system. Background technique [0002] Clinically, spinal fusion is the primary method of treatment of spinal disorders, intervertebral fusion device has been widely used in the cervical and lumbar spinal fusion surgery. In spinal fusion surgery, immediately after the fusion has achieved stability, distraction and maintain disc height and promote integration, etc., which in clinical use has been rapid development. At the same time, because they do not match the specifications and pathology of the patient environment led to the sinking of the cage after the cage, displacement, not fusion fusion failure phenomenon has drawn increasing attention. So, how for each particular patient pathology environment targeted for cage design, customization services to achieve fusion, not only in academic research, a refer...
