不仅能看清，还要更顺手：国产内镜在镜体优化上正中临床痛点

Core Viewpoint - The article emphasizes the evolution of gastrointestinal endoscopy technology, particularly focusing on the new generation of endoscopes that address the real needs of doctors, enhancing operational efficiency and patient experience through structural innovations [2][20]. Upper Digestive Tract - The challenges in upper digestive tract procedures are not just about access but also about maintaining visibility and stability during operations, especially in complex areas like the gastroesophageal junction and pylorus [3][4]. - The introduction of a new endoscope with a bending angle of 160° significantly improves the ability to approach and control difficult areas, enhancing the overall operational experience for doctors [4][3]. Lower Digestive Tract - The article discusses the importance of Cecal Intubation Time (CIT) as a key performance indicator in lower digestive tract procedures, where longer CIT indicates greater difficulty and discomfort for patients [8]. - The CAST system introduced in the new endoscope series optimizes the insertion experience by adjusting stiffness, adapting to bending, and ensuring precise transmission of movements, thereby improving operational efficiency [10][18]. Technical Innovations - The new endoscope features three core functionalities: adjustable stiffness to enhance support efficiency, adaptive bending to follow the anatomy, and precise transmission for better control, all aimed at reducing the burden on doctors during procedures [12][16][13]. - These innovations are not merely incremental changes but represent a systematic response to multiple pain points faced by doctors, particularly in challenging clinical scenarios [18][21]. Conclusion - The article concludes that the new generation of endoscopes, particularly the 650 series, focuses on refining operational details rather than making disruptive changes, aiming to provide a more user-friendly experience for doctors [20][21]. - The emphasis is on understanding the operational experience from the doctor's perspective, which is crucial for the current landscape of high-end domestic endoscope manufacturers seeking breakthroughs [21].
