An endoscopic carrier with complete directional control: design principles

Area of Science:

• Medical Devices
• Gastroenterology
• Robotics

Background:

• Endoscopic examinations of the upper and lower digestive tracts are crucial for diagnosis and treatment.
• Current endoscopic tools can face challenges navigating complex anatomical structures like curves and flexures.
• A need exists for improved maneuverability and ease of use in endoscopic instruments.

Purpose of the Study:

• To describe a novel carrier system for endoscopic instruments.
• To introduce a mechanism for enhanced control and navigation within the digestive tract.
• To facilitate easier and more effective endoscopic examinations.

Main Methods:

• Development of a carrier composed of articulated segments.
• Integration of magnetic clutches to control angular displacement between segments.
• Implementation of a system where the leading segment's angle is automatically replicated by subsequent segments.
• Inclusion of a central channel for instrument passage.

Main Results:

• The carrier demonstrates the ability to navigate curves and flexures effectively.
• The magnetic clutch system allows for precise control over the carrier's articulation.
• The automatic angle replication ensures consistent guidance along the entire carrier length.
• The central channel accommodates standard endoscopic instruments.

Conclusions:

• The described endoscopic carrier offers a significant advancement in navigating the digestive tract.
• This technology has the potential to simplify endoscopic procedures, particularly in the upper and lower digestive tracts.
• The innovative design promises to enhance the ease and efficiency of endoscopic examinations.
