Laparoscopic surgery has many ergonomic disadvantages often not considered in the design of instruments. The poorly designed surgical tools produce inconveniences in both functional and cognitive aspects; including tactile sensation and visual-motor space coordination. The aim of this article is to find out how laparoscopic handle design can be improved by combining classical ergonomic guidelines with tactile feedback related to handle design. The article briefly discusses how the human hand and hand-held tools are used to perform tasks. An ergonomic handle for laparoscopic grasping, with a built-in tactile sensation display, is presented. Our review of laparoscopic instruments reveals important aspects for handle design. It is concluded that there is a need for greater awareness of ergonomic guidelines for users' sensory requirements when designing and manufacturing laparoscopic instruments.
腹腔镜手术存在许多人体工程学方面的劣势，而在器械设计中这些劣势常常未被考虑到。设计欠佳的手术工具在功能和认知方面都会带来不便，包括触觉感受以及视觉-运动空间协调。本文的目的是探究如何通过将经典人体工程学准则与手柄设计相关的触觉反馈相结合来改进腹腔镜手柄的设计。本文简要讨论了人手及手持工具是如何用于执行任务的。还展示了一种用于腹腔镜抓握的人体工程学手柄，其内置了触觉感受显示器。我们对腹腔镜器械的审查揭示了手柄设计的重要方面。得出的结论是，在设计和制造腹腔镜器械时，需要更多地关注符合用户感官需求的人体工程学准则。
