3D printing technology is a technology based on digital model data, which uses an adhesive material to create an object model by layer-by-layer printing, that is, a 3D solid model is formed by layer-by-layer superposition of materials. As a new type of rapid prototyping and rapid manufacturing technology, it has attracted more and more attention, and it has also been favored by scholars in the medical field. 3D printing technology has been applied in the medical field, which mainly includes the following: (1) 1:1 solid model; (2) biologically inactive materials; (3) biologically active tissue cells and complete life functions organ.
Recently, Dinghai Guanghua Hospital introduced 3D printing technology for the treatment of patients with bone injuries, which is the first in the city! The advantages are great: not only the surgical trauma is greatly reduced, but also the operation time and medical expenses are greatly shortened and reduced.
The first patient to receive this technical treatment was a Mr. Dong. At the beginning of this month, Mr. Dong suffered from comminuted fractures in his ankle due to a car accident and the injury was serious.
In the past, such complicated operations can only be diagnosed by doctors through CT and other two-dimensional images, and then the damaged parts and conditions. The surgeon needs to have solid anatomical knowledge, strong spatial imagination, rich clinical experience and perfect preoperative design. Even with the above conditions, patient individualized differences can lead to increased difficulty in surgery and increased operating time.
Considering the multiple comminuted fractures of Mr. Dong's ankle, the operation is difficult and the operation time is long. After communicating with the patient's family, the attending physician Zhou Chao broke through the conventional thinking and proposed using 3D printing technology to assist in surgical treatment. That is, the patient's damaged part is scanned by high-resolution CT, and then the data is transmitted to the computer for processing, connected to a dedicated 3D printer , and printed into a 1:1 simulation model.
According to Zhou Chao, in this high-simulation model made of corn starch, Mr. Dong’s several fractures are clear at a glance. The doctor designed the surgical plan accordingly, made a support plate that is more conformable to the bone, and pre-operatively on the model. Perform the simulation.
Half a month ago, the doctor officially operated for Mr. Dong. The doctor referred to the model and was targeted. The operation time was also cut in half. At present, Mr. Dong’s recovery is good. "Before we showed us the CT film, we couldn't understand it. This model can intuitively let us know the injury situation, the surgery is done well, the recovery is also very fast, and it can be walked down in a few days." The patient's family said .
