System topology diagram
As depicted in the above figure, one set of surgical teaching carts is equipped in the operating room. Portable surgical teaching interactive terminals, high-definition surgical field cameras, and panoramic cameras can be installed on it to collect surgical image signals for different surgical needs. The surgical process information is collected and stored, and the video and audio signals are transmitted through the network to the simulation center conference room inside or outside the hospital for real-time live broadcasting and interactive communication.
In the operating room, through the surgical teaching cart, not only can audio and video signals of the operating room be collected, such as those from panoramic cameras, surgical field cameras, medical equipment video signals, and wireless two-way earphones audio signals. After encoding, files can be recorded and saved on a local USB drive or mobile hard drive and uploaded to a third-party FTP server for file storage and archiving, facilitating users to download files and watch and play on demand. It can also engage in real-time remote interaction with personnel at the simulation center, achieving remote teaching observation.
At the simulation center end, the 4K surgical teaching interactive terminal (named 1169) can remotely observe the panoramic view of the operating room and ultra-high-definition images of surgical field equipment in real time and can also communicate with the operating room through voice communication. At the same time, personnel at the simulation center can freely choose single-screen, multi-screen, or multi-screen display to observe the entire surgical process based on the actual situation of the surgical scene and display equipment. In addition, by deploying surgical teaching interactive terminals through voice terminals, the surgical teaching cart can interact with the family chat room or leadership office.
Surgical teaching cart
The surgical teaching cart (as shown in the figure below) employs a modular design. It is equipped with modules such as a 4K portable surgical teaching terminal, panoramic camera, surgical field camera, and omnidirectional microphone for easy installation. This product is furnished with an electric lifting structure and ultra-quiet medical wheels, enabling it to be easily and flexibly moved to the operating room.
Surgical demonstration
One surgical teaching cart is deployed in the operating room. It adopts a highly integrated and portable design, integrating a video conferencing terminal, video matrix, and environmental control. It supports 4K ultra-high-definition signal acquisition and H.264 and H.265 encoding. It can achieve audio and video signal interoperability with any classroom/conference room, with a picture quality of up to 4K ultra-high definition. Viewers can observe the surgical process from multiple angles and in all directions and engage in voice communication. It is a remote teaching platform specifically designed for hospitals, medical schools, and medical training institutions, including a camera system (with panoramic and surgical field dual camera positions), voice interaction system, display system, medical image acquisition and coding system, and control management system. The deployment is simple, convenient, flexible, highly reusable, and cost-effective.
Image Resource Management
The audio and video content of the surgical process can be saved locally in the operating room or uploaded to the image resource management server of the cloud control center for centralized storage in the demonstration room. It supports on-demand playback and can be directly viewed on the HDMI output at the same time.
Surgical video recording
Real-time recording of the surgical process in all aspects and multiple scenes, providing traceable video files.
Real-time live streaming
Push the surgery process to the Internet live broadcast platform in real time for users to watch through computers or mobile devices.
Video on demand
Classify and manage surgical images, provide convenient and fast retrieval, on-demand, and download services, and support multiple platforms.
Distance learning
Hospital distance education mainly comprises two training modes: real-time live streaming and courseware on-demand. Real-time live training ensures the synchronization of audio and video of teaching experts and supports real-time interaction among training participants. The intelligent medical remote teaching and training system employs computers and networks for remote teaching, achieving synchronous images, sounds, and interactive teaching between teaching parties in different locations, attaining goals that traditional distance education cannot reach.
Intraoperative communication
Through the interactive function of the surgical teaching terminal in the operating room, synchronous communication with pathologists regarding pathological sampling requirements, resection range, result feedback, and report return is possible, reducing the waiting time for intraoperative pathological examinations.
During the surgical process, if there are special circumstances that require communication with family members, the surgical images and information will be communicated to the patient's family in multimedia format. The surgeon can complete the intraoperative conversation without leaving the operating room. The authorized images of the conversation and family confirmation are saved throughout the surgical demonstration interactive terminal and can also be uploaded to the control center for centralized storage to avoid postoperative disputes between doctors and patients.
Remote visitation
An ICU visitation room is established. Family members enter and the visitation task is initiated by the nurse station. Once the visitation is completed, the task is stopped to ensure the safe and controllable transmission of images. The visitation terminal has a two-way audio and video visitation function. Through high-definition cameras and audio systems, it can achieve two-way audio and video interaction and visitation, meeting the needs of patients' families to pay attention to the surgical process and conduct remote visitation, and addressing the difficulties of ICU ward visitation.
Simulation center end
The surgical teaching interactive host (select a louder device name) supports SIP and H.263 interactive protocols and can achieve 4-party high-definition video interaction on its own. It can also register and connect to a remote expert consultation platform. It interconnects audio and video signals for remote expert consultations or conducts remote consultations and centralized consultations with lower-level hospitals.
