Spinal intervertebral foramen surgery model and manufacturing method thereof

Abstract

The invention discloses a spinal intervertebral foramen surgery model. The model comprises an artificial spine composed of multiple segments of artificial vertebral bones,an artificial intervertebraldisc located between every two adjacent artificial vertebral bones,an intervertebral disc protrusion simulated object bonded to each artificial intervertebral disc and artificial tissue wrapped on theexterior of the artificial spine; the intervertebral disc protrusion simulated objects are made of viscose fibers and bonded to arbitrary positions of the corresponding artificial intervertebral discs. The intervertebral disc protrusion simulated objects made of the viscose fibers can be glued to appropriate positions outside the corresponding intervertebral discs to simulate different types of intervertebral disc protrusions,and the shape and size of the intervertebral disc protrusion simulated objects can be adjusted according to needs to be better in line with the real state of the human body. Compared with a traditional mode of using corpses or non-dedicated models for training,the model has the advantages that the cost of training doctors can be greatly reduced,the repeatability is excellent,surgical modes are diversified,and the training period can be shortened.

Description

technical field [0001] The invention relates to a medical teaching and experiment model, in particular to a spinal intervertebral foramen mirror operation model. Background technique [0002] The growth of a surgeon is inseparable from the accumulated practical experience. Professional training can improve the professional level of doctors, but in fact there are not so many opportunities for surgical practice. At present, most doctors are trained through autopsy. Due to the limited sources of cadavers and the high cost, high-simulation surgical models can more conveniently provide surgeons with operating opportunities and improve their surgical skills. However, there are few surgical models currently available, mainly involving the head and neck, limbs, pelvic cavity, kidneys and other organs, and their structures are relatively simple, so they are not suitable for multiple operations. [0003] With the continuous development of minimally invasive surgical techniques, spina...

Problems solved by technology

But at the same time, the problem is that almost all the surgical models that can be used for reference are disposable or reusable. Although the training cost is lower than that of autopsy, it still cannot fully meet the needs of teaching. demand, especially for transforaminal endoscopic surgery with a long learning curve
