Look at the omnipotent 3D printing technology, shocking and realistic 3D film and television, and 3D pictures with fake real pictures. While it brings us a strong audiovisual impact, it is also changing our lives. Believe it or not, the era of the 3D industrial technology revolution has arrived. In the 3D era, the medical field is also undergoing rapid changes with each passing day. Academician Zhong Shizhen pointed out that digital medicine technology represented by three-dimensional reconstruction and visualization simulation technology is changing the traditional mode of disease diagnosis and treatment and medical teaching, and has realized the transformation from digital people to digital medicine, becoming a model of translational medicine.
According to 39 Health Network, since 2002, under the guidance of Professor Zhong Shizhen, the founder of digital medicine in China and academician of the Chinese Academy of Engineering, Fang Chihua has joined experts and scholars in imaging, anatomy, computer science, hepatobiliary and pancreatic surgery, simulation and physics to form a team to conduct clinical application research on digital medicine technology in hepatobiliary and pancreatic surgical diseases. On the basis of China's "digital person" technology research, the team has successfully broken through the bottleneck of sub-millimeter image data acquisition of human abdominal organs after several years of efforts on the platform of the "Eleventh Five-Year Plan" and "Twelfth Five-Year Plan" National 863 Program, developed and completed the three-dimensional visualization system of abdominal medical images with independent intellectual property rights and CFDA qualification certification (MI-3DVS), and applied the system to carry out personalized three-dimensional reconstruction, diagnostic analysis, simulation surgery and guidance of surgery for hepatobiliary pancreatic and spleen surgical diseases.
Visualized simulation surgical systems reduce surgical risks
Professor Fang Chihua, director of the First Department of Hepatobiliary medicine of Zhujiang Hospital of Southern Medical University, said that the biggest advantage of the visual simulation surgical system is that it can repeatedly operate and correct the pre-operation program design and planning, so as to completely remove the lesion and minimize the trauma to the patient. It truly realizes the digitization, diagnostic programming and surgical visualization of the individualized anatomy of the living human body, so that the abdominal surgery has changed from the previous "one-cut success or failure" to the "rehearsal" that can be repeatedly "rehearsed" on the computer before surgery, which effectively avoids the surgical risk, reduces the intraoperative decision-making time, and significantly improves the success rate of the operation.
Compared with traditional imaging diagnosis, the use of digital three-dimensional visual technology has increased the resectability rate of liver tumors by 7.0%, the rate of hepatobiliary stone remnants has decreased from 25%-30.25% reported in the past literature to less than 3.0%, and the resectability rate of pancreatic tumors has increased by 10%.
The next step is to combine intraoperative 3D ultrasound with preoperative 3D visualization
Speaking of the future, Fang Chihua revealed that the team is currently studying, based on the previous use of digital 3D laparoscopy, combined with intraoperative navigation, a new project of "three-dimensional visualization combined with 3D laparoscopic precision liver resection navigation technology" to explore the feasibility of widespread minimally invasive resection of complex liver cancer.
In addition, Professor Fang Chihua said that he hopes to have a new breakthrough in 3D printing on the liver and create a functional 3D printed liver. Talk about how to do it? Professor Fang Chihua pointed out that first of all, the liver entity should be 3D printed, close to the real entity, and secondly, the physiological function of the liver should be studied, and the liver pipe mechanics and fluid medicine also need to be clarified, and finally the physical elastic function may also need to be tested. "Although the current technology does not reach this point, after taking a small step, who can say that there will not be a big step immediately." (Correspondent: Hu Qiongzhen)
