Extension Mechanism of a Flexible End for Colonoscopy

Area of Science:

• Medical Devices
• Gastroenterology
• Endoscopy

Background:

• Colonoscope insertion depth is limited in certain colon configurations.
• A longer insertion tube is often required for complete colon examination.
• The distal tip extension mechanism (DTEM) addresses these limitations.

Purpose of the Study:

• To develop and investigate a novel distal tip extension mechanism (DTEM).
• To evaluate the DTEM's ability to extend the colonoscope's distal tip by 16 cm.

Main Methods:

• The DTEM was tested in a colonoscopy training model (CTM) with a silicon tube.
• The mechanism's extension capability was measured in various colon configurations.
• The impact of DTEM implantation on insertion tube flexibility was assessed.

Main Results:

• The DTEM successfully extended the colonoscope's distal tip by 16 cm.
• The mechanism performed effectively across different colon configurations.
• The DTEM's effect on insertion tube flexibility was characterized.

Conclusions:

• The developed DTEM is a promising tool for enhancing colonoscopy.
• This mechanism can assist colonoscopists in performing more effective colonoscopies.
