Front view and panoramic side view videoscope lens system design

Area of Science:

• Medical Devices
• Optical Engineering
• Endoscopy

Background:

• Rigid endoscopes are crucial for minimally invasive procedures.
• Current designs may face limitations in field of view and image quality.
• Aberrations from protective covers can degrade image clarity.

Purpose of the Study:

• To present a novel rigid panoramic endoscope design.
• To address image quality challenges in endoscopic imaging.
• To introduce a system for aberration correction.

Main Methods:

• Designed a rigid panoramic endoscope with a dynamic mechanical lens module.
• Integrated microgears and motors for lens component actuation.
• Incorporated a compensation element to correct optical aberrations.
• Attached a long depth of field navigator lens for front-side imaging.

Main Results:

• Demonstrated a novel endoscope structure with panoramic imaging capabilities.
• Successfully corrected aberrations caused by the endoscope's protective cover.
• Achieved enhanced imaging of the target field with the dynamic lens system.
• Validated the performance of the navigator lens for front-side visualization.

Conclusions:

• The novel rigid panoramic endoscope design offers improved visualization.
• The dynamic lens system and aberration correction are effective.
• This design has potential applications in various endoscopic procedures.
