握得顺手，做得长久：从开立看内镜设计的新边界

Core Viewpoint - The evolution of medical devices is a gradual process that requires a focus on user experience, particularly through Human Factors Engineering, to enhance safety, comfort, and efficiency in medical equipment design [1][3][18]. Group 1: Importance of Human Factors Engineering - Human Factors Engineering integrates the physiological, psychological, and behavioral characteristics of users to improve product safety and efficiency [3][18]. - A local company, Kaili Medical, has made significant strides in applying Human Factors Engineering by studying doctors' hand movements and fatigue during procedures [3][4]. Group 2: Impact of Ergonomic Design on Medical Professionals - Studies indicate a high prevalence of musculoskeletal pain among endoscopists, with 95.08% reporting pain, and 19.7% specifically in the hands [4][5]. - The design of medical devices often overlooks the user experience, prioritizing technical specifications over comfort, which can lead to long-term health issues for medical professionals [5][6]. Group 3: Innovations by Kaili Medical - Kaili Medical's new endoscope operation unit focuses on reducing the physical strain on doctors by implementing ergonomic design changes [7][9]. - Key innovations include a 20% reduction in handle weight and a 15% decrease in thickness, which help alleviate muscle fatigue during prolonged use [9]. - The design also features a 30% reduction in handwheel resistance, making it easier for users, especially those with smaller hands, to operate the device [11]. Group 4: Design Features Enhancing User Experience - The button layout is designed to mimic natural finger movements, allowing for seamless operation without changing grip, thus enhancing workflow continuity [13][14]. - An ergonomic grip design aligns with the natural contours of the hand, improving comfort during extended use [16][17]. - The overall design improvements reflect a deep understanding of user experience, emphasizing the importance of considering the user's physical and cognitive demands [17][18]. Group 5: Broader Implications for the Industry - The evolution of medical devices should not only focus on performance but also on the well-being of the users, addressing the diverse needs of medical professionals [18][19]. - Companies are encouraged to adopt a user-centered design approach, which can lead to improved service quality and greater satisfaction among healthcare providers and patients alike [18][19].
