A dual-view multi-resolution laparoscope for safer and more efficient minimally invasive surgery

Area of Science:

• Surgical Technology
• Medical Imaging
• Minimally Invasive Surgery

Background:

• Traditional laparoscopes in minimally invasive surgery (MIS) have limitations in safety and efficiency due to their hand-held nature and narrow fields of view.
• These limitations can hinder surgical precision and increase operative risks.

Purpose of the Study:

• To introduce and evaluate a multi-resolution foveated laparoscope (MRFL) designed to overcome the limitations of conventional laparoscopes.
• To assess the feasibility of an MRFL prototype for improving surgical visualization and efficiency.

Main Methods:

• Development of a stationary, dual-view imaging device with optical panning and zooming capabilities.
• Integration of features such as a snub-nosed endoscope, tool-tip auto tracking, programmable focus, selectable display modalities, foot pedal controls, and independent displays.
• Construction and testing of an MRFL prototype to validate design and functionality.

Main Results:

• The MRFL prototype successfully demonstrated its design architecture and the functionality of its integrated features.
• Optical panning and zooming allowed for repositioning of the zoomed view without physical system movement.
• Testing confirmed the prototype's adequate performance as a proof of concept.

Conclusions:

• The developed MRFL prototype serves as a viable proof of concept for advanced surgical imaging.
• Further improvements in system features and performance are necessary for the MRFL to be clinically applicable.
• The MRFL technology holds potential for enhancing safety and efficiency in minimally invasive procedures.
