Minimally invasive surgery (MIS) is limited in safety and efficiency by the hand-held nature and narrow fields of view of traditional laparoscopes. A multi-resolution foveated laparoscope (MRFL) was invented to address these concerns. The MRFL is a stationary dual-view imaging device with optical panning and zooming capabilities. It is designed to simultaneously capture and display a zoomed view and supplemental wide view of the surgical field. Optical zooming and panning capabilities facilitate repositioning of the zoomed view without physically moving the system. Additional MRFL features designed to improve safety and efficiency include its snub-nosed endoscope, tool-tip auto tracking, programmable focus profiles, unique selectable display modalities, foot pedal controls, and independently controlled surgeon and assistant displays. An MRFL prototype was constructed to demonstrate and test these features. Testing of the prototype validates its design architecture and confirms the functionality of its features. The current MRFL prototype functions adequately as a proof of concept, but the system features and performance require further improvement to be practical for clinical use.
微创手术 (MIS) 受到传统腹腔镜手持操作和有限视场的限制，在安全性和效率方面受到限制。为了解决这些问题，发明了多分辨率注视腹腔镜 (MRFL)。MRFL 是一种具有光学平移和缩放功能的固定双视图成像设备。它旨在同时捕获和显示手术区域的缩放视图和补充的宽视图。光学缩放和平移功能便于在不实际移动系统的情况下重新定位缩放视图。旨在提高安全性和效率的其他 MRFL 功能包括其短鼻内窥镜、工具尖端自动跟踪、可编程焦点轮廓、独特的可选显示模式、脚踏控制器以及独立控制的外科医生和助手显示器。构建了一个 MRFL 原型来演示和测试这些功能。原型的测试验证了其设计架构，并确认了其功能的有效性。当前的 MRFL 原型作为概念验证足够有效，但系统功能和性能需要进一步改进，才能实际用于临床应用。
