Continuum Robots for Medical Interventions

Area of Science:

• Robotics
• Medical Devices
• Minimally Invasive Surgery

Background:

• Continuum robots, unlike traditional jointed robots, achieve motion through continuous bending along their entire structure.
• Their flexible, narrow form factor is ideal for navigating complex anatomical pathways like body lumens and surgical incisions.
• The inherent complexity in modeling and controlling these robots stems from diverse flexure mechanisms, often developed in isolation.

Purpose of the Study:

• To provide a unified overview of continuum robot architectures tailored for clinical applications.
• To present a cohesive framework for modeling and controlling continuum robot systems.
• To identify key research advancements and future directions for widespread clinical adoption.

Main Methods:

• Systematic review of existing continuum robot architectures and their design principles.
• Development of a unifying framework for modeling and control applicable across different architectures.
• Analysis of research accomplishments and identification of challenges for clinical implementation.

Main Results:

• Categorization and summary of various continuum robot designs based on their flexure mechanisms.
• Introduction of a generalized modeling and control framework applicable to diverse continuum robots.
• Highlighting of significant research progress in continuum robot design and control for medical applications.

Conclusions:

• A unified approach to modeling and control is crucial for advancing continuum robot technology.
• Standardized frameworks will accelerate the development and clinical integration of these robots.
• Further research is needed to overcome remaining challenges for widespread clinical use in minimally invasive procedures.
