"Bones" can also be 3D printed
News Summary: Recently, Quanzhou than the neighboring three-dimensional Technology Co., Ltd. and 180 hospitals to cooperate in the research and development of innovative applications of 3D printing project. The project through the combination of 3D printing technology and orthopedic diagnosis and treatment, can greatly improve the success rate of orthopedic surgery, reduce surgical incisions, shorten the recovery time by 30%.
1:1 model to realize the surgery preview
Recently, Quanzhou than the neighboring three-dimensional science and technology limited company and the 180 hospital cooperation research and development of 3D printing innovative application project. The project through the combination of 3D printing technology and orthopedic diagnosis and treatment, can greatly improve the success rate of orthopedic surgery, reduce surgical incisions, shorten the recovery time by 30%.
1:1 print bone model
Jiangxi 15-year-old girl Fang (a pseudonym) with her parents in Jinjiang life, a car accident caused her craniocerebral injury, acetabular fracture. Because it was a comminuted fracture, traditional surgery would likely not have been able to reset it properly, and could have even led to lifelong disability. However, it is gratifying to see that, due to the application of 3D printing technology in 180 hospitals before the operation "early intervention", the doctor before the operation through this technology to print out a 1:1 bone model, after repeated surgical rehearsals, the attending surgeon ultimately in the implementation of the operation to achieve accurate and rapid completion of the operation, time-consuming than in the past to save half of the patient's bleeding, surgical injury is also greatly reduced. Bleeding, surgical damage is also greatly reduced.
The reporter learned that this is 180 hospitals and Quanzhou than the neighboring three-dimensional science and technology limited company cooperation of bone mode 3D printing project a successful case. "In the past, the doctor can only determine the patient's bone lesions through the plane CT film, combined with the doctor's usual experience out of thin air in order to prepare for the next surgery, and develop a surgical program. Now, 3D printing makes the CT slice three-dimensional, allowing doctors to more accurately predict the risk of surgery." Ltd. general manager Lin Fengchun told reporters that the production of bone models should first be combined with the patient's injured bone related information to establish a data model, "to collect hundreds of data, one by one stacked into a body image." All data, technicians have to check several times, the error can not exceed 1 millimeter. After that, the 3D printer will be able to "copy" the patient's "skeleton" in a few hours. The material used to print the model is resin, and only the "rough embryo" was printed for more than 8 hours.
Surgery in advance
With a 1:1 model, all intraoperative processes can be carried out in the model, and the required pre-bending of the steel plate into the appropriate curvature before the operation, which really turns the ordinary steel plate into a "customized steel plate". All intraoperative problems can be pre-designed before the operation, and the length of the steel plate and screws can be known before the operation. This improves the precision of the surgery, speeds up the process, and reduces the patient's pain.
It is understood that at present, due to material limitations, 3D printed bone can only be used as a model, and can not be directly used to replace human bone. However, with the advancement of material technology, metal-based 3D printing consumables will also be gradually applied to the field. Currently, titanium separation nails made through 3D printing have been produced and will soon enter the animal experiment stage.
