China's first surgery with 3D printing + AR technology

Central hospital successfully implemented vertebral tumor resection + vertebral body replacement surgery with "AR+3D printing" technology

This technology is applied to the field of orthopedics and is the first in the country.

On March 21st, Weihai Central Hospital successfully completed a giant spindle cell tumor resection and vertebral body replacement surgery through "AR (augmented reality) technology" and "3D printing technology" high-tech means. A successful attempt at 3D printing technology in orthopedic surgery. In the course of this operation, AR technology and 3D printing technology are perfectly applied to the field of orthopedics, which is the first in the country.

Cutting-edge medical skills: "AR technology + 3D printing" Resection of tumors, replacement of vertebral bodies

Not long ago, Lin Qing (a pseudonym), who lives in Wendeng District and is 66 years old, was unable to go to the Weihai Central Hospital for examination. The doctor accidentally discovered that he had a ball-sized mass in his abdomen. After multidisciplinary consultation, combined with CT, magnetic resonance and puncture. The pathological examination results were taken and identified as low malignant lumbar spine tumors. Because the tumor erodes the fifth vertebral body and is huge, if it is not treated in time, the patient is at risk at any time.

At present, surgical resection is still the key to treatment for tumor invasion of the lumbar vertebral body. Taking into account the actual situation of the patient, the attending physician communicated with the patient's family in detail, and finally decided to implement 3D printed vertebral body replacement for lumbar tumor resection for Lin Qing. Based on medical image data, 3D printing technology was used to make personalized artificial vertebral body. Intraoperative implantation into the patient to establish a new stable system for the lumbar spine.

At 8:50 on the 21st, intense surgery began. Taishan scholars hired experts, Weihai Central Hospital Dean Chong Haibo, senior surgeon of spinal surgery Zhang Enzhong, director of traumatic orthopedic surgery Ma Zhaoqiang and other experts to perform surgery, vascular interventional surgery, urology , anesthesiology, imaging, blood transfusion, operating room and other multidisciplinary experts work together, with the AR technology provided by Shanghai Linyi Technology, the patient's abdomen 11 cm × 9 cm × 6 cm size of the tumor was completely removed, and successfully implanted The 3D printed metal vertebral body lasted more than 4 hours. The patient's vital signs were stable during the whole operation and the operation was completed as planned.

While the doctor was wearing AR glasses for surgery, the reporter observed it through an external screen. Through the AR glasses transmission, the reporter feels that he is on the operating table. The doctor controls the AR glasses through voice and gestures, and switches the display of arteries, veins and bones during the operation and drags and pans. The reporter can pass An external screen is used to see this fine surgery from the surgeon's field of vision.

It is understood that 3D printing technology is applied to orthopedic surgery, which is not uncommon in Weihai Central Hospital. Not only is it used on a large scale for acetabular fracture surgery, but it is also very mature in the application of major orthopedic tumor resection. The application of the AR technology enables the patient's blood vessels, tissues and lesions to appear 360 degrees in front of the doctor, greatly increasing the safety of the operation and improving the accuracy of the operation.
