Problems solved by technology

The rapid development of computer software replaces the human brain to reconstruct the image in three dimensions to form a lifelike three-dimensional image. Unfortunately, the three-dimensional image is displayed on a plane and is affected by multiple factors, such as the thickness of the CT scan, the quality of the computer software, The operating level of the technicians, etc., the images presented to us are not clear enough, real, and even give people an illusion

Embodiment 1

[0025] The material used for printing the cervical structure is composed of the following raw materials in weight percentage, 60 parts of polyamide, 40 parts of oxidized starch, 5 parts of calcium carbonate, 0.5 part of hydrogenated pinoresinol, 40 parts of bisphenol A epoxy resin; the printed spinal cord, nerve The materials used are composed of the following raw materials in weight percentage, 40 parts of polyamide, 20 parts of polypropylene, 25 parts of oxidized starch, 5 parts of calcium carbonate, 0.1 part of hydrogenated pinoresinol, 20 parts of rosin resin, and 10 parts of bisphenol A epoxy resin. Print directly with the materials mentioned above.

Embodiment 2

[0027] The material used for printing the cervical structure is composed of the following raw materials in weight percentage, 100 parts of polyamide, 50 parts of oxidized starch, 5 parts of calcium carbonate, 0.5 part of hydrogenated pinoresinol, 20 parts of bisphenol A epoxy resin; The materials used are composed of the following raw materials in weight percentage: 60 parts of polyamide, 45 parts of polypropylene, 25 parts of oxidized starch, 5 parts of calcium carbonate, 0.1 part of hydrogenated pinoresinol, 40 parts of rosin resin, and 5 parts of bisphenol A epoxy resin. Separate the outer surface of the spinal cord and nerve models within a depth of 0.1-0.3 mm through software to form a fluorescent layer. The material for printing the fluorescent layer is to add ultraviolet fluorescent substances to the materials used for printing the spinal cord and nerves. Every 100 weight 3 parts of ultraviolet fluorescent substances are added to the materials used for printing the spina...

Embodiment 3

[0029] The material used for printing the cervical structure is composed of the following raw materials in weight percentage, 70 parts of polyamide, 45 parts of oxidized starch, 5 parts of calcium carbonate, 0.5 part of hydrogenated pinoresinol, 20 parts of bisphenol A epoxy resin; the printed spinal cord, nerve The materials used are composed of the following raw materials in weight percentage, 60 parts of polyamide, 30 parts of polypropylene, 25 parts of oxidized starch, 5 parts of calcium carbonate, 0.1 part of hydrogenated pinoresin alcohol, 25 parts of rosin resin, and 6 parts of bisphenol A epoxy resin.

[0030] Separate the outer surface of the spinal cord and nerve models within a depth of 0.1-0.3 mm through software to form a fluorescent layer. The material for printing the fluorescent layer is to add ultraviolet fluorescent substances to the materials used for printing the spinal cord and nerves. Every 100 weight 1.5 parts of ultraviolet fluorescent substances are add...

Abstract

The invention relates to a method for manufacturing an auxiliary model for cervical vertebra operation. Cervical vertebra scanning data are processed by computer software, and cervical vertebras, bones, intervertebral disc, blood vessels and nerve structures can be separated according to density difference of different tissues. A three-dimensional image is divided into two parts, a front central pillar and a rear pillar through computer software, and converted into formats which are identifiable by a 3D printer. The printer prints out the two parts of models, the cervical vertebra structures are printed with transparent and hard materials, the intervertebral discs are printed with red and soft materials, and the spinal cords and nerve roots are printed with hoary soft materials. The method helps a doctor to better observe a pathological parts and to make a more reasonable operation scheme. The method helps patients and their family members lack of related medical knowledge to know the conditions of the patients and obtain informed consent. The operation time is substantially shortened, bleeding during an operation is reduced, and the incidence rate of various complication is minimized.

Description

technical field [0001] The invention relates to a method for making an auxiliary model for cervical spine surgery. Background technique [0002] Imaging medicine is the eye of clinical medicine. The discovery and medical application of X-rays have greatly promoted the diagnosis and treatment of various clinical disciplines, especially orthopedic diseases. After the invention of the computer, it has had a qualitative impact on all aspects of society, and medicine is no exception. The combination of X-ray and computer produces CT, that is, computerized tomography, which realizes people's dream of "cutting apart" the human body for observation, but the doctor's brain needs to superimpose the images layer by layer, and combine his own anatomical and clinical knowledge to It forms a three-dimensional concept. So, images of the same patient may be different in the brains of different doctors. The rapid development of computer software replaces the human brain to reconstruct ima...
