Before surgery, a medical model is obtained by 3D modeling based on the patient's CT or MRI data, and then the model is printed out by a 3D printer. The main function of 3D printing medical models is to allow doctors to intuitively see the three-dimensional structure of the surgical site before surgery, which helps doctors plan surgical plans. Especially for complex surgeries, it helps to reduce the risk of surgery and improve the success rate of surgery.

In osteoarticular surgery, precise surgical planning is crucial. Through 3D printing technology, doctors can make accurate skeletal models based on the patient's CT scan data. These models not only help surgeons better understand the anatomy of lesions, but can also be used to simulate the surgical process, thereby increasing the success rate of the surgery and reducing the operation time. Such a model can not only help doctors better plan surgical strategies, but also can be used for communication between doctors and patients, helping patients to understand their own disease conditions and surgical procedures more intuitively.

In repair surgeries for complex fractures or bone defects, it is critical to ensure the precise docking of the implant to the bone. 3D printing technology can be used to design and fabricate surgical guides that can guide surgeons to make precise cuts and drills, improving surgical precision, reducing operation time, and reducing the risk of complications.

Traditional joint replacements use standardized prostheses, which often do not fit perfectly into the bone structure of each patient, and in some cases, the patient's bone defects or diseases are complex and varied, and traditional standardized implants often cannot meet the treatment needs. Using 3D printing technology, doctors can customize implants based on the patient's specific anatomical characteristics. This personalized implant better matches the patient's own bones, providing a better biomechanical match and increased safety, improving surgical outcomes and patient comfort.

For complex fractures or bone defects, traditional treatments may not provide the best results. 3D printing technology can print the corresponding bone or scaffold structure according to the specific situation of the patient, making fracture repair or bone defect filling more accurate and effective. A further application is 3D bioprinting, which allows the printing of biomaterials containing living cells for repair or regeneration of damaged bone tissue. This technique is still in its infancy, but in the future it is expected to enable complete tissue engineering to fundamentally solve the problem of tissue damage and organ loss.

3D printing medical models can be used not only for surgical planning and simulation, but also as a tool for medical education and surgeon training. These models can help students and interns understand the complex skeletal anatomy, and then practice on the models, thereby accumulating experience, providing a more realistic and interactive learning experience than traditional teaching, which will help future doctors develop and improve their surgical skills.
