Abstract: In response to bottlenecks such as multi-source data integration and large-volume video data processing in traditional operating rooms, this paper proposes and develops a cloud-based digital surgical video management platform. By integrating cloud architecture with intelligent technologies, we have established a comprehensive digital surgical data ecosystem covering scientific research, education, and quality control throughout the entire workflow. The platform features interfaces with all hospital surgical systems and achieves normalized audio-visual signal processing through unified client deployment in operating rooms, supporting parallel processing of 8-channel high-definition videos per case. Implementing a tiered storage strategy for surgical video data, it overcomes limitations of traditional local storage capacity. Innovatively incorporating cross-platform collaboration capabilities, the system enables scientific data mining. Built-in video editing tools including timeline synchronization, dynamic layout switching, and subtitle annotation significantly reduce operational complexity for medical staff. Clinical applications demonstrate that the platform achieves 93.2% online video storage rate post-implementation, with 98.5% of stored videos undergoing online editing. Surgeons can efficiently create educational videos, while postoperative video reviews dynamically correlate intraoperative field visuals with monitoring data, optimizing procedural workflows and strengthening quality control systems. This platform development provides a replicable technical template for smart hospital construction, serving as critical infrastructure for promoting healthcare resource homogenization and digital transformation.
