Remote surgery teaching and medical consultation opens the new era of hospital

Hospital operation teaching and telemedicine system is a video communication system which uses computer video communication technology to record and transmit real-time images of clinical diagnosis or operation scene for long-distance teaching, long-distance observation and long-distance diagnosis. This paper introduces the application characteristics and trends of the teleoperation teaching and telemedicine consultation system, which is based on the remote video communication platform of Shenzhen Tenveo Company and H.264 high-definition video camera.

In the application of surgical teaching, clinical teaching, as an important task of many hospitals, shoulders the heavy responsibility of training medical and nursing personnel. The training method is usually on-site observation. However, due to the limitations of the site conditions or surgical equipment, the space for on-site surgical observation is narrow, and the participants are restricted. At the same time, it brings unnecessary trouble to the normal treatment of patients, and the effect is not ideal. The rapid development of video communication technology has brought new opportunities for the realization of long-distance visual teaching in hospitals. Many large and medium-sized hospitals urgently need to build high-quality hospital clinical network teaching system. But in the telemedicine consultation application, the doctor obviously can complete the medical diagnosis directly through the video communication system without spending too much time on the road, and even can launch the telemedicine consultation according to the patient's condition.

In fact, in the face of the continuous maturity and rapid development of today's video communication system, we can see that the video communication system has been fully capable of these more advanced applications in hospitals. Manufacturers in the field of video communication are gradually introducing and improving this kind of operation teaching and telemedicine system through the combination of technology and application. Among them, the operation teaching and medical consultation system developed by Beijing Huaweixun Company is gradually emerging. This system can accomplish various functions of teaching and consultation through a comprehensive video processing, video exchange and video transmission platform, and the front-end combined with high-definition video camera based on H. 264.

Convenient and fast medical video communication

Video surveillance and relay teaching system is a video communication system based on IP network, which integrates video surveillance, video real-time two-way interaction, video storage and sharing, remote video browsing and other functions. The network cameras which support H. 264 compression standard are adopted in the system. They have the advantages of lower storage requirement, faster frame speed and higher resolution, and significantly improve the storage capacity of high resolution video in the whole system application process. Especially the megapixel cameras set up in some key areas have wider coverage, and can provide excellent clarity and image details.

Through this system and H. 264 high-definition camera, it can not only realize the convenient long-distance surgery observation and teaching, but also realize the fast long-distance guidance. The core functions are as follows:

1) real-time remote surgery teaching

Operation teaching is a necessary means of clinical teaching in hospital. In order to improve the quality of operation and reduce the infection rate of operation, the operating rooms of the hospital have formulated the control index of the number of observers in the operating room and strictly controlled the number of people entering the operating room. This has greatly reduced the opportunities for interns to learn to observe the operation and is not conducive to improving the interns. The quality of learning. Video monitoring and broadcasting teaching system can be used to observe the operation process through a large screen outside the operating room and carry out real-time teaching. It not only reduces the cross infection in the operating room, but also ensures the aseptic requirement in the operating room. At the same time, it also enlarges the scope of operation teaching, thus getting rid of the limitation of traditional teaching mode in time, space and number.

2) real-time expert tele consultation.

Through the system, experts do not need to enter the operating room, can watch real-time high-definition images of surgery in the conference room, with the on-site doctor to confirm the diagnosis of patients, and surgery guidance; when the on-site surgery is more complex, through the network through the teaching terminal to form an operation seminar, in time to solve difficult surgical problems.

3) video storage and query.

The image data acquired by H. 264 high-definition camera has high definition, good imaging effect and high compression quality, which can provide a very clear real-time recording of surgical images and scene video for the system.

Through the high quality and long time storage of the operation process, it can be effectively used for future teaching. Some controversial operations can use these video data as the basis for scientific judgement. After the operation, the comparison of these imaging data for academic discussion and research, can effectively improve the level of surgery doctors.

In addition, the system can take pictures of the operation site, and allow pre-set scene image observation position, in the learning process can quickly change the observation point, but also can use wireless network, emergency or major surgery in temporary settings without rewiring.

Integration of medical video communication system integration

The video surveillance and teaching system is divided into four subsystems: video transmission subsystem, interactive video teaching subsystem, remote diagnosis and treatment video communication subsystem and exchange control subsystem. Among them, the first three subsystems realize the remote video teaching and diagnosis functions, belonging to the functional subsystem, the fourth system belongs to the background support subsystem. The four systems are integrated and designed to form an integrated medical video communication system.

1) operation room video transmission subsystem

Operating room subsystem is a digital image acquisition and coding system, each operating room has two channels of video, through the installation of H.264 high-definition field camera, as well as high-definition panoramic surveillance camera for image acquisition, and the use of omni-directional pickup microphone, the master knife doctor's voice and the voice of the entire operating room real-time transmission. Teaching and teaching rooms. The system transplants the audio and video signals of the operation room to the teaching end through compression.
