Research on One-hole Split Endoscope (OSE) technology is garnering increasing attention. This study aims to delineate the global landscape and emerging trends within this field. Literature publications on OSE from January 1, 1992, to March 1, 2025, were retrieved from the Web of Science Core Collection's Science Citation Index Expanded. The sourced data were examined and indexed utilizing bibliometric methodologies. For the visualization analysis, VOSviewer software (version 1.6.19) was employed to conduct co-authorship, co-occurrence, bibliographic coupling, and co-citation analyses, thereby elucidating the overarching trends in OSE research in recent years.A total of 819 articles were retrieved. The volume of global OSE research and publications has demonstrated a consistent annual increase. The United States contributed the most significantly to global OSE research, attaining the highest citation counts and the highest h-index. Springer Nature and Elsevier published the highest number of relevant articles. Wooridul Spine Hospital, the University of California System, Seoul National University (SNU), and Seoul St. Mary's Hospital were identified as the four most prolific institutions. Research foci could be categorized into three primary clusters: neurosciences, surgical procedures, and orthopedics. Surgical procedures are projected to be the next prominent hotspot in the field. Based on current global research trends, the number of publications related to OSE is anticipated to continue rising. The United States currently stands as the leading contributor to this domain. The majority of future research efforts are expected to concentrate on clinical studies, particularly OSE surgical techniques, which are likely to represent the next research frontier. The findings of this study provide clinicians and researchers with a comprehensive overview of the global development of OSE technology, its core research entities, and future directions, thereby offering a bibliometric evidence base for tracking technological frontiers, selecting international collaborators, and determining priorities in clinical research.
