3D printing technology shows up in the medical field
3D printing technology appeared in the mid-1990s. It works in the same way as ordinary printing. The printer is equipped with "printing materials" such as liquid or powder. After connecting with the computer, the "printing materials" are layered by computer control, and finally the blueprint on the computer is turned into a real object. This printing technique is called 3D stereo printing technology. In recent years, 3D printing technology has rapidly changed people's lifestyles in various fields, and the medical community has begun to use it extensively. Recently, the Department of Orthopaedics, Department of Orthopaedics, Taizhou Medical Center, Taizhou, used 3D printing technology to accurately complete a high-risk neck and neck deformity surgery.
Li Dashu is 53 years old. His cervical spine was born from a deformity. In the past half century, his cervical deformity has become more and more serious, affecting not only the image, but also his life. In order to solve this problem, he had sought medical treatment everywhere, but the effect has been unsatisfactory. At the beginning of this year, there was a situation in which the hands and feet were numb and weak, and even life was difficult to take care of. After a series of diagnoses at Taizhou Hospital, Li Dashu was diagnosed with dystrophic neurofibromatosis.
Hong Zhenghua, director of the Department of Orthopaedics of the Department of Orthopaedics, Taizhou Medical Center, Taizhou: "It should have been the neck 1 attached to the front of the neck 2. Now the neck 1 suddenly ran to the rear and severely oppressed the spinal cord, causing him to have no left hand or foot. strength."
If left untreated, the spinal cord will become heavier and heavier, eventually endangering life. At present, only timely surgical reduction of spinal decompression surgery can prevent the progression of dislocation. The plan was fixed, but it encountered some problems.
Hong Zhenghua, director of the Department of Orthopaedics, Department of Orthopaedics, Taizhou Medical Center, Taizhou: "The cervical vertebra has 7 nodes, arranged in a circular line. This patient has a severe kyphosis, plus many bone structure defects, no development. After seeing such a patient, I can't start. There are a lot of routine neck 1.2 procedures. Relatively speaking, the risk is not big, but we can't start this patient."
In order to understand Li Dashu's spinal curvature more clearly and intuitively, and to develop a detailed surgical plan, Hong Zhenghua decided to use 3D printing technology to assist surgery. 3D printing is a pre-operative "helper" that helps doctors accurately locate the surgical area.
Hong Zhenghua, director of the Department of Orthopaedics, Department of Orthopaedics, Taizhou Medical Center, Taizhou: "Through CT, put it in 3D printing, print it in 1:1, and make the bone structure exactly the same. We can do a simulated operation on it first. How do we routinely play nails, and all the patients on the right side are missing, there is no chance to nail."
Hong Zhenghua finally found a chance to put a nail in the pedicle and lamina of the neck 2 by pre-operation on the 3D specimen.
