According to the patient’s CT or MRI scan data, use dedicated modeling software to complete the 3D model reconstruction, and print out the color, soft and hard combination of the patient’s bone lesions and injuries through the Senna WJP direct-injection color multi-material 3D printing technology. Print the model. Clearly and intuitively help doctors formulate surgical plans, complete surgical process planning, and assist in the design of personalized surgical instruments, which greatly reduces the occurrence of emergencies in the clinical operation stage and shortens the operation time.
|Apply for a hospital||Guangdong Provincial People's Hospital||Patient condition||He Moumou female 9 years old|
|Condition description||Weakness of lower limbs, falls for more than 7 months, aggravated in late April and December, there is no obvious cause of weakness of lower limbs; unable to stand or walk on their own in February of the following year, X-ray and CT examinations suggest possible neurogenic tumors; income in Guangdong in June Provincial People's Hospital.|
|Surgery difficulties||Based on two-dimensional CT images, doctors have a relatively abstract grasp of the position, size, and shape of the patient's collateral vessels, making it difficult to accurately determine the specific conditions of the collateral vessels. During the operation, the patient is unable to carry out its own blood circulation, so it is necessary to perform extracorporeal circulation on the patient. The longer the extracorporeal circulation, the higher the postoperative complication rate and the overall risk. There are many complications in the operation, including but not limited to breathing. Functional impairment, brain damage, etc.|
|treatment plan||With the help of full-color 3D printing models, the size and shape of the tumor and the surrounding important tissue structure surrounding and invasion are restored 1:1, combined with multiple departments for preoperative surgical planning, and 3D models are used for navigation during the operation to remove the lesions.|
|advantage||Soft red: artery Soft blue: veins Soft green: tumor Hard white: bony tissue Through the full-color 3D printing model combined with hardware and software, doctors can clearly and intuitively determine a personalized surgical plan. Reduce the risk of surgery, know the distribution of large blood vessels near the bone tumor, and avoid the possibility of hemorrhage during surgery.|
This type of fracture is mainly caused by direct violence, mostly comminuted fractures, and is a more complicated operation in trauma orthopedics.
Dislocation of the prosthesis due to long-term loosening causes deformation of the femur. Improper position of the prosthesis is the main cause of loosening. Incorrect implant position will cause uneven force on the prosthesis, and insufficient amount of bone cement or bio-stem filling will make the prosthesis unable to withstand overload.
Using full-color soft and hard printing, the green tumors and red arteries are printed with soft materials, which can simulate tumor peeling before surgery...
According to Muller classification, this case is type C2, which is one of the most serious fractures of the distal femur. This type of fractures are mostly comminuted fractures, which are difficult to fix. The fractures are close to the knee joint, spread to the articular surface, and easily affect joint movement. It is one of the most difficult fractures to treat.
Benign tumor in the middle of the humerus. Multicolor combined with transparent printing can clarify the size of the tumor before surgery and provide a basis for cleaning the lesion before surgery. And can pre-form the steel plate/determine the size of the allogeneic bone according to the printed 3D model.
