Chinanews.com, Beijing, July 22. Question: What is the "unique" of breaking the foreign monopoly of the cardiovascular OCT system independently developed by China?

"In the past 20 years, the number of PCI surgeries in China has surged. In 2019, it has exceeded one million cases. Accurate treatment is imminent. Intracavitary imaging technology can accurately evaluate PCI surgeries and allow patients to receive the most effective treatment." Professor Ge Junbo, academician of the Chinese Academy of Sciences, recently Said at an online conference.
PCI stands for coronary intervention surgery, also known as heart stent surgery. At this "2020 Cardiac Imaging and Cardiac Intervention Conference", the "Cardiovascular OCT (Optical Coherence Tomography) System" independently developed by Chinese researchers for 8 years was officially launched, breaking the long-term monopoly of such products by foreign products situation.
Where does the domestic cardiovascular OCT system come from?
Professor Chen Yundai, Dean of the Graduate School of the Chinese People's Liberation Army General Hospital and director of the Department of Cardiovascular Medicine, introduced that the low-light cardiovascular OCT system is an incubation and key support project of the Xi'an Institute of Optics and Mechanics, Chinese Academy of Sciences. Dr. Zhu Rui, Dr. Li Jianan, and Dr. Cao Yihui, the leading figures of low-light medical research and development, have made great achievements in OCT system research and development and medical image intelligent analysis research. Their team successfully developed cardiovascular 3D as early as 2013. —OCT, after another 7 years of engineering and clinical registration.
Professor Chen Yundai said that during the research and development process, R&D personnel constantly communicate with clinical experts to understand the operation thinking and habits of surgeons, use experience and surgical needs; innovatively developed OCT-Angio system, bifurcation lesion quantitative evaluation system, and biodegradable Many more intelligent scientific research functions such as automatic analysis of biological stents and one-key sharing.
"The low-light medical cardiovascular OCT system has a unique Pencil-beam technology, and the imaging depth is better than imported similar products. In terms of image depth and details, especially intelligent service software has certain advantages." She said.
What are the unique features of the domestic cardiovascular OCT system?
At the meeting, two experts from the Department of Cardiovascular Medicine of the Chinese People's Liberation Army demonstrated its imaging effects and innovative functions with actual cases. Among them, when Jin Qinhua introduced the two cases of low-light OCT to guide the treatment of bifurcation lesions and the placement of degradable stents, she said that the device can calculate the branch opening area through 3D reconstruction to optimize bifurcation treatment strategies and accurately guide the placement of degradable stents. The application of PSP technology in the process of implantation; Gao Lei used low-light OCT to guide the case of in-stent restenosis with severe calcification as an example. OCT has more advantages than IVUS in the analysis of the thickness of calcified lesions and the properties of new plaques in the stent. The imaging catheter of low-light OCT is also very smooth in passing.
Experts said that the stability of the low-light OCT imaging catheter optical fiber probe is very good, and there is no breakage of the optical fiber probe in various pathological applications in clinical trials. "The bifurcation, angle measurement, and branch area measurement of this equipment's scientific research analysis function cannot be measured on the latest imported OCT machine." said Professor Zeng Hong from Jiangxi Provincial People's Hospital.
In addition, the Chinese operating interface of the device is simple and easy to use, following the seven-step method of OCT operation, in line with the operating thinking of Chinese doctors.
Follow-up plan for domestic cardiovascular OCT system
Zhu Rui, the founder of Low Light Medical, said that he will continue to deepen the R&D and innovation of interventional intracavitary imaging technology, thoroughly implement the innovative concept of medical-industry integration, refine the products, and actively promote the localization of high-end medical devices.
He and his team are building a new generation of multi-modal fusion (four-in-one) intracavity imaging system, which will be easier to use and smarter, and is planned to be launched in 2021.
Zhou Yujie, executive vice president of Beijing Anzhen Hospital affiliated to Capital Medical University, said that although the low light OCT started late, it started from a high starting point and overcome some weaknesses from the beginning. Participants also look forward to more domestically-made manufacturers in the field of high-end medical devices to achieve corner overtaking. With more accurate imaging guidance, lower prices, and smarter surgical methods, more patients with coronary heart disease can get more accurate diagnosis and treatment. (Finish)
