Gastroscope segmentation follows a comparable dual‑layer structure. Application categories include Diagnostic Endoscopy, Therapeutic Endoscopy, Screening Programs, and Research/Training. Diagnostic endoscopy remains the backbone, sustaining steady volume as hospitals conduct routine examinations; Therapeutic endoscopy, encompassing polypectomy and hemostasis, adds higher‑margin revenue streams. Screening initiatives, driven by public‑health policies, expand the user base, while Research and Training generate ancillary demand for advanced models. Types are classified as Standard, High‑Definition (HD), Capsule, and Ultra‑thin gastroscopes. Standard devices meet baseline diagnostic needs, whereas HD gastroscopes command premium pricing due to superior image resolution, influencing market uplift. Capsule gastroscopes, though limited to specific screening scenarios, introduce a disruptive revenue channel. Ultra‑thin models address patient comfort and access constraints, supporting niche procedural markets. Collectively, these application‑type intersections delineate the gastroscope’s contribution to the overall market taxonomy.
