A Novel Articulating Chip-on-Tip Endoscope for Dynamic Middle Ear Surgical Visualization

Area of Science:

• Medical Devices
• Surgical Technology
• Otolaryngology

Background:

• Pediatric middle ear surgeries often require invasive procedures like mastoidectomies due to limited visualization.
• Standard endoscopes have inherent limitations in articulation and field of view within the complex middle ear anatomy.

Purpose of the Study:

• To introduce and evaluate a novel Articulating Chip-on-Tip Endoscope (ACoT Endo) for enhanced visualization in pediatric Otolaryngology middle ear surgeries.
• To assess the potential of the ACoT Endo to reduce the instances of mastoidectomies.

Main Methods:

• The ACoT Endo features a cable-driven distal end camera and a Chip-on-Tip camera, designed for improved visualization and articulation.
• Bending capacity (70° ± 2°) and center axis rotation (360°) were evaluated.
• Functionality was tested using a Mock Ear simulating human ear anatomy, comparing the ACoT Endo against a standard 0° Karl Storz endoscope.

Main Results:

• The ACoT Endo provided visualization comparable to standard endoscopes, with an approximate 69% increase in field of view and a 249% increase in captured area compared to the 0° Karl Storz endoscope.
• The device allowed for effortless camera articulation with simple finger rotation, facilitating procedures like middle ear excision.
• Surgical details were accurately captured, demonstrating its utility in ENT procedures.

Conclusions:

• The ACoT Endo offers dynamic viewing angles and superior visualization within the middle ear via a single, highly articulate endoscope.
• Its capabilities present significant potential benefits for Otolaryngology procedures, improving surgical outcomes and safety in pediatric middle ear surgeries.
