Those who have seen the "Grey of Intern" will not be familiar with 3D printing technology. In the TV series, the doctor used this technique several times to treat the patient's scene, which has amazed many audiences and even medical staff. In fact, the application of 3D printing technology in the medical field has long been unconsciously integrated into the lives of Zhongshan people.
Collecting the patient's image data, applying the 3D technology to print the 1:1 model of the affected limb, planning the precise nail navigation mold according to the 3D solid model of the affected limb and the various torsion angles in the three-dimensional space of the affected area... Not long ago, with the help of 3D printing technology, The 15-year-old Wu Feng (a pseudonym) was successfully corrected for his right hand due to a fracture. The author learned from Zhongshan People's Hospital and Zhongshan Hospital of Traditional Chinese Medicine that the current 3D printing technology has been applied and explored in the oral and orthopaedic fields of some hospitals in Zhongshan. In the future, patients in Zhongshan will receive more accurate treatment.
Orthopedic patient with minimal trauma to assist skeletal deformity
Half a year ago, Wu Feng (pseudonym), 15 years old, suffered a fracture of the upper forearm of the right forearm due to accidental fall. After the treatment, the daily care was not in place, the healing of the affected area was poor, and the activity of the right forearm was limited, which affected the daily activities. Subsequently, after X-ray review, Wu Feng was diagnosed as a deformity of the upper right humerus fracture.
"Patients need orthopedics and functional reconstruction. If they are not treated, they will seriously affect his normal life in the future." Gao Dawei, chief physician of orthopedics at Zhongshan Hospital of Traditional Chinese Medicine, said, "Because the traditional method of orthopedics needs to remove part of the bones of patients, in order to Minimizing the trauma of surgery, the team of joint specialists decided to implement precise osteotomy and functional reconstruction for patients through 3D printing technology."
It is understood that before the operation, the doctor collected the patient's image data, applied the 3D technology to print the 1:1 model of the affected limb, and designed the precise nail navigation according to the 3D solid model of the affected limb and the various torsion angles in the three-dimensional space of the affected part. The mold, and the preoperative pre-operation such as the surgical approach selection, the preset position of the internal fixation, and the optimal shaping design of the internal fixation.
Due to a series of well-prepared preoperative preparations, the patient only needs to expose part of the bone surface during the operation. The doctor places the 3D nail guide navigation mold and sequentially drills the internal fixation according to the pre-designed procedure. In this way, the surgery does not need to cut off the patient's bone, and the deformity can be corrected smoothly.
Gao Dawei said that the 1:1 simulated partial fracture model printed by 3D printing technology can not only help the surgeon to fully understand the fracture type and severity of the injury before surgery, but also simulate the actual operation. In the operation, the rapid positioning of the fracture fragments, the more accurate reduction, the shorter operation time, less intraoperative blood loss, simple operation during operation, and less pain of the patient are achieved.
