On April 10, 2022, in the operating room of the Second Inpatient Department of Peking University First Hospital, Professor Li Xuesong of the Department of Urology is performing pyeloplasty with the help of the domestic Condor endoscopic robotic surgical system; at the same time, a few kilometers away in Peking Union Medical College In the telemedicine center of the hospital, Professor Ji Zhigang from the Department of Urology observed and monitored the whole operation in front of the doctor console of the Kangdo surgical robot. During the operation, the surgical steps such as dealing with anatomical variation were taken over by Professor Ji Zhigang from Xiehe, who remotely controlled the surgical robot arm located in Peking University Hospital to complete real-time interactive teaching guidance and surgical operations. During the operation, the two parties switched and controlled multiple times, the process was smooth, the 3D high-definition video on the remote end was clear and smooth, the robotic arm responded in a timely and stable manner, with no obvious delay, and the operation was accurate and effective; the voice and scene video interaction between the two parties was perfect, and the assistants cooperated tacitly, and the operation was successfully completed. . This marks the world's first successful exploration of the cross-operator and cross-domain "5G + fixed-line dedicated line" multi-point collaborative remote clinical real-time interactive teaching and surgical model.
Q Explore a new model of cross-operator and cross-domain collaboration
5G network is a new generation of broadband mobile communication technology with high speed, low latency and large connection. Expanding its application in the medical industry will effectively enable telemedicine. At present, the construction of 5G infrastructure in more developed areas in China is growing rapidly, but due to the fact that many district, county, and prefecture-level hospitals in China currently only have fixed network coverage, cross-regional remote surgery based entirely on 5G networks has not yet been realized.
In addition, my country's current communications industry, China Mobile, Telecom and China Unicom, are three pillars, serving my country's communications business together. The development of telemedicine will inevitably encounter cross-operator situations. Therefore, based on the current status of domestic fixed network services covering a wide range, combined with the advantages of high-speed and low-latency 5G networks, we innovatively use 5G networks and fixed-line private lines for cross-domain and cross-operator network transmission channels, and in non-operators. Under the special guarantee environment, the fixed-line dedicated line uses 30M ordinary bandwidth to restore the actual scenario of remote surgery applications at this stage as much as possible, and ensure the implementation of remote surgery through technical means.
The cross-operator and cross-domain "5G + fixed-line dedicated line" model is more in line with the current basic national conditions of my country, which is conducive to improving the medical technology level and diagnosis and treatment efficiency of hospitals in different regions, and can better serve the construction of a hierarchical diagnosis and treatment system and medical poverty alleviation. and other work to effectively enhance the majority of patients' sense of gain in the field of medical and health care.
Q Realize a new breakthrough in remote real-time whole-process supervision
The previous single-console remote surgery mode of surgical robot has many problems such as ethical safety and medical responsibility, especially because the chief surgeon is far away from the patient, when a sudden or abnormal situation occurs during the operation, the surgeon cannot handle it on the spot, which increases the medical risk. Seriously hinder the development of telesurgery.
This remote surgery adopts a multi-point collaborative remote real-time interactive teaching mode. During the initial stage of robotic surgery or the learning period of complex surgery by local physicians, the control rights of remote multi-point consoles are transferred to realize the whole process of local surgery. Remote medical experts Real-time supervision and teaching operation of key steps of surgery greatly reduce the medical risk of local surgeons during the learning period, reduce the rate of open transfer, improve the success rate of surgery, and enable local physicians to learn in the process of practical operation, speeding up their operations skill growth. If the network is interrupted or the remote console fails, the local doctor will continue to use the local console to operate the surgical robot to complete the subsequent surgery, which controls and reduces the risk of remote surgery.
Q Technology helps the sinking of high-quality medical resources
The domestic Condom laparoscopic robotic surgery system attempted the world's first remote animal surgery based on 5G network in December 2018; in September 2019, it successfully implemented the world's first multi-point collaborative 5G remote animal surgery; October 2021, Beijing The Urology Department of the University's First Hospital successfully implemented a dual-console remote animal surgery test between the central campus and Miyun Hospital, which is 80 kilometers apart, using a fixed-line dedicated line; in March 2022, the Peking Union Medical College Hospital Telemedicine Center and Peking University First Hospital will operate The laboratory jointly completed the remote surgical operation test of 5G + fixed line dedicated line. The development and technical testing of the above basic experiments have provided solid technical support and confidence for the successful implementation of remote clinical surgery.
The multi-point collaborative remote real-time interactive surgery mode reduces the medical risk of a single remote console robot remote surgery, and can solve the problem of uneven distribution of high-end mature medical personnel resources caused by regional development differences. Make full use of new technologies, new businesses, and new models to enrich the forms of medical assistance, expand the connotation of telemedicine services, and improve the accessibility of medical services, in line with the Healthy China strategy of promoting the sinking of high-quality medical resources to the grassroots.
