Solution application topology
As shown in the above figure, the operating room collects surgical image signals through high-definition surgical field cameras and panoramic cameras to gather and store surgical process information for operations with different requirements. The teaching signals are stored in the storage device through the network via the teaching terminal. Real-time rebroadcasting or later on-demand broadcasting is carried out for local area network users within the hospital and Internet users outside the hospital through the network. Whether in the classroom, office, or anywhere outside the campus, high-definition teaching activities can be fully received and watched through mobile terminals. At the same time, the operating room and the family chat room or classroom can interact through voice terminals. All audio and video files are stored in large capacity through storage servers.
Operation room
The operating room is the information source for the learning system. The scene at the surgical site, surgical results, and the language of the doctor on site are the main elements in teaching. Usually, one or more high-definition coding terminals are deployed in the operating room. These terminals collect and transmit multi-channel video from the operating room to the display room and remote consultation rooms.
a. Panoramic camera: Used for capturing panoramic video information of the operating room.
b. High-definition camera: For capturing surgical details.
c. Endoscopic videos.
d. The wireless microphone transmits the voice of the chief surgeon in real time to the classroom.
e. Optionally access various medical instruments in the operating room, such as cardiac blood pressure monitoring equipment, X-ray machines, etc.
In each operating room, the surgical demonstration interactive host is employed to achieve audio and video collection. According to the type of surgery and actual needs, video signals from panoramic cameras, surgical field cameras, medical equipment, and wireless two-way earphones are gathered. The encoded audio signals can be recorded and saved locally and uploaded to a third-party FTP server for file storage and archiving, facilitating users to download files and watch on-demand playback.
One surgical teaching interactive host can support the simultaneous recording of 10 video signals. Multiple operating rooms or classrooms can be centrally managed through a comprehensive management platform, which saves costs and facilitates later management and maintenance.
Showroom/Consultation room
The showroom provides a centralized environment for observation, learning, and interactive Q&A for a large number of customers. It is usually equipped with large-screen display devices such as multiple projectors and flat TVs.
The teaching terminal decodes high-definition audio and video from the network and directly outputs it to large display devices. Users can flexibly switch between on-site surgical video images, control the pan-tilt and camera, conveniently combine and display multiple surgical video images, and support bidirectional voice and visual intercom.
The demonstration classroom can have two-way audio interaction with the operating room through the demonstration terminal.
System function
The operation teaching system uses Internet technology to display all panoramic activities and surgical section activities in the operating room on the large screen in the teaching room, enabling observers to watch the entire surgical process in the teaching room. Of course, this requires the assistance of hardware devices such as 1080p high-definition surgical field cameras and panoramic cameras to capture the surgical incision image and the operating room panoramic view respectively.
At the same time, in order to ensure bidirectional intercom between the teaching room and the operating room, the surgical teaching demonstration system also requires the assistance of equipment such as microphones, speakers, and pickups to jointly create a convenient and easy-to-use teaching assistance software. The application of this system avoids the infection caused by personally entering the operating room for observation and greatly improves the efficiency of clinical teaching, ensuring that most people can observe the expert's surgery at once.
