Characteristic information can be shown incisively and vividly on screen；
2nd, surgery demonstration system should have two way audio function：Earphone-microphone and control room, operating room or teaching can be passed through
Room carries out two-way or multidirectional real-time exchange, while audio system should avoid echo and problem of uttering long and high-pitched sounds, and avoids unexpected generation sonic boom
Surgical procedure is interfered；
3rd, surgery demonstration system should have recording function：The picture of operating room can be recorded simultaneously in a manner of manually and automatically
And audio, the recording, storage and playback of more image modes are supported, supports full HD or high, SD mixing recording function.
4th, surgery demonstration system should support remote expert consultation function：Need to consider access remote expert consultation system, specially
Family, professor also can carry out remote operation guidance in office by the system to front end operating room, be carried out with point-of-care personnel
Bidirectional audio-video is interactive, and expert can be clearly seen that operation details, can accurate judgement surgery situation propose directiveness in time
Opinion.
