Description

Technical Field

[0001] The present invention belongs to the technical field of 3D printing, and in particular relates to a method for automatically 3D printing a therapeutic product according to medical data. Background Art

[0002] In the traditional pharmaceutical industry market, biomaterials mass-produced in factories can no longer meet the needs of patients. In the medical field, patients have obvious individual differences, complex body tissues, and are too sensitive to price. They need biomaterials that are more in line with the patient's pathological characteristics to assist in treatment. The emerging 3D printing technology, with its advantages of personalization, small batches and high precision, can easily solve the contradiction between the personalized needs of the health industry and the scale of production.

[0003] With the development of 3D printing technology, its application is becoming more and more extensive. Among them, the aerospace and medical fields are the industries that use 3D printing technology most deeply. After several years of development, 3D printing technology has significant applications in precision medicine. 3D printed medical surgical guides, surgical models and implant surgeries are mainly used in 16 departments such as orthopedics, oncology, dentistry, hepatobiliary, and urology.

[0004] Traditional product design is completed through 3D printing, but it does not bring out the true value of 3D printing. More often, it is necessary to break through the limitations of design thinking and give full play to the free modeling advantages of 3D printing. The marginal cost of complexity of 3D printing is almost zero, that is to say, the more complex the geometric shape of the product, the more cost-effective it is to process it through additive manufacturing. 3D printing also has the advantages of personalized customization, complex geometric shapes, and functional integration.

[0005] However, most of the existing technologies remain at the stage of using 3D printing technology for product design, and fail to fully utilize the advantages of 3D printing in free modeling, complex geometric shape processing, etc. Summary of the invention

[0006] The purpose of the present invention is to provide a method for automatically 3D printing therapeutic products based on medical data, so as to solve the problems of lack of personalization, insufficient precision and high production cost of therapeutic products in the prior art.

[0007] To achieve the above object, the present invention provides the following technical solution: a method for automatically 3D printing a therapeutic product based on medical data, comprising the following steps:

[0008] Obtaining medical data of patients through computerized tomography or magnetic resonance imaging;

[0009] Use software to convert the collected 2D image data into a 3D model;

[0010] Using a 3D printer, materials are stacked layer by layer according to the constructed three-dimensional model to form the required therapeutic product. Medical devices, implants or other therapeutic products can be manufactured according to the specific needs of each patient.

[0011] The specific steps for acquiring data by computed tomography are as follows:

[0012] The patient is placed in the circular opening of the circular detector of the computed tomography device and needs to adopt a specific position depending on the part of the body to be examined;

[0013] The X-ray source and detector in the computed tomography device rotate together around the patient, projecting X-rays from different angles and acquiring imaging data;

[0014] The computer performs reconstruction calculations based on the energy attenuation of the X-rays received by the detector as they pass through different tissues, ultimately presenting a cross-sectional image.

[0015] As a preferred technical solution of the present invention, the specific steps of acquiring data by magnetic resonance imaging are as follows:

[0016] The patient is placed on the examination bed of the MRI device. Depending on the part of the body to be examined, the patient needs to adopt a specific posture and wear earplugs to reduce noise interference;

[0017] Magnetic resonance imaging equipment uses magnetic fields and radio frequency pulses to make hydrogen nuclei in the human body resonate, and obtains imaging data by collecting these resonance signals;

[0018] As a preferred technical solution of the present invention, a computer processes the collected resonance signals to reconstruct a three-dimensional image of the inside of the body.

[0019] As a preferred technical solution of the present invention, the method for converting the collected two-dimensional image data into a three-dimensional model using software is as follows:

[0020] Import the two-dimensional image data obtained from computer tomography or magnetic resonance imaging into professional medical image processing software;

[0021] The two-dimensional images are registered to ensure the correct positional relationship between the layers of the images; then the image is segmented to separate the area of ​​interest from the background;

[0022] Using the 3D reconstruction algorithm in the software, the segmented 2D image data is converted into a 3D model;

[0023] The reconstructed three-dimensional model is optimized.

[0024] As a preferred technical solution of the present invention, the three-dimensional reconstruction algorithm in the software is used to convert the segmented two-dimensional image data into a three-dimensional model by interpolation and smoothing to improve the accuracy and smoothness of the three-dimensional model.

[0025] As a preferred technical solution of the present invention, optimizing the reconstructed three-dimensional model includes removing noise and filling holes.

[0026] As a preferred technical solution of the present invention, a 3D printer is used to stack materials layer by layer according to the constructed three-dimensional model to form the desired therapeutic product. The corresponding method is as follows:

[0027] Export the optimized 3D model to a file format recognizable by the 3D printer;

[0028] Set printing parameters on the 3D printer;

[0029] The 3D printer builds up the printing material layer by layer according to the geometry of the 3D model;

[0030] After printing is completed, the treatment product undergoes necessary post-processing.

[0031] As a preferred technical solution of the present invention, the file formats include STL and OBJ.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] Ensure that the therapeutic product is highly matched to the patient's anatomy through precise data collection and model building;

[0034] Customize treatment products according to individual differences of patients to meet their personalized needs;

[0035] 3D printing technology allows for the low-volume, low-cost production of complex therapeutic products;

[0036] Precise, personalized treatment products help improve patient outcomes and satisfaction. BRIEF DESCRIPTION OF THE DRAWINGS
