Recently, Weihai Central Hospital successfully completed the resection of a large sacrococcygeal tumor of the sacrococcygeal vertebral body and vertebral body replacement through "AR (Augmented Reality) Technology" and "3D Printing Technology" high-tech means. This is the hospital's 3D printing technology A successful attempt in orthopedic surgery. In the course of this surgery, AR technology and 3D printing technology applied to the field of orthopedics, is the first case in the country.
Not long ago, Lin Qing (a pseudonym), 66, was unable to visit Weihai Central Hospital. The doctor accidentally found a ball-size mass in his abdomen. After multidisciplinary consultation, combined with CT, magnetic resonance and needle biopsy results , Identified as low-grade lumbar spine tumors.
At present, for tumor invasion of lumbar vertebrae, surgical resection is still the key to treatment. Taking into account the actual situation of patients, the attending physician finally decided to Lin Qing implementation of lumbar tumor resection 3D printing vertebral body replacement, based on medical imaging data, the use of 3D printing technology to produce personalized artificial vertebral body, intraoperative implantation of the patient , The establishment of a new lumbar stability system.
During the operation, the doctor controls the picture displayed by the AR glasses through voice and gestures, and switches the display of the arteries, veins and bones during surgery to drag and translate.
It is understood that 3D printing technology used in orthopedic surgery in Weihai Central Hospital is not uncommon. Not only for large-scale acetabular fracture surgery, the application of major orthopedic resection has been very mature. The application of AR technology, so that the patient's blood vessels, tissues, lesions 360 degrees presented in front of the doctor, greatly increasing the safety of surgery and improve the accuracy of surgery.
Today, AR technology is not just a "seemingly beautiful" concept, not just like ordinary people want to see the video, playing games so simple. In fact, AR technology is in "close contact" with traditional medicine. The surgery, the use of CT, MRI multi-angle film, the computer restored a virtual but very realistic human body structure, patients and doctors can be more clear how to implement the operation.
Taishan scholar Distinguished experts, Weihai Central Hospital Cong Haibo introduction, the entire surgical process is the most important thing is to seamlessly connect AR technology and real surgery. In surgery, if you encounter tricky parts, you can wear glasses, glasses swept place, the field of vision there will be a realistic virtual scene, the real environment and virtual objects appear in real time on the same screen or space, two The kind of information complement each other, the patient's entire site structure will be crystal clear. Surgery is like a long "perspective of the eye", you can see the tumor directly through the skin location, size, depth, to avoid the important blood vessels, nerves, tissue and improve surgical safety.
