Portable Gas Spring with Rachet and Pinion System as a Third Arm for Holding Endoscope in Two Handed Endoscopic ENT...

Area of Science:

• Otolaryngology
• Medical Device Design
• Surgical Technology

Background:

• Endoscopic middle ear surgery has evolved from an adjuvant role to exclusive practice.
• A key limitation of current endoscopic ear surgery is the single-handed technique, where the non-dominant hand is occupied holding the endoscope.

Purpose of the Study:

• To propose and design a novel portable endoscope holder.
• To facilitate two-handed endoscopic ear surgery by providing a stable, hands-free platform for the endoscope.

Main Methods:

• Concept development and design of a portable endoscope holder.
• The device utilizes a gas spring action and rack and pinion system to function as a 'third arm'.

Main Results:

• The designed endoscope holder acts as a stable, independent support for the endoscope.
• The system is portable and designed for integration into existing surgical workflows.

Conclusions:

• The developed portable endoscope holder addresses the significant limitation of single-handed technique in endoscopic ear surgery.
• This device has the potential to enhance outcomes in various two-handed endoscopic ear, nose, and throat surgeries.
