Soft Colonoscopy Robotic Platform
Each year, colon cancer claims the lives of more than 600,000 people worldwide, and is the fourth leading cause of cancer-related death in the world. Like other cancers, colon cancer progresses to malignancy in approximately 5 – 10 years; however, it possess the unique quality that if the tumor is detected at an early enough stage the prognosis for survival is 90%. For this reason, it is recommended that people over 50 years of age or people who have a family history of colon cancer undergo routine screenings for colon cancer every five years.
The focus of our research platform (shown in the image below) is two-fold: to increase patient compliance with these lifesaving recommendations by first decreasing the pain associated with the procedure, and expand the capabilities of traditional colonoscopy by introducing automated computer assistance. Navigating the endoscope is achieved by magnetic coupling, which allows for pulling the capsule endoscope from the front, rather than pushing the traditional colonoscope tube from the back, which can lead to painful stretching of the colon. The image below shows the components of the system. This platform is an evolution of the Magnetic Air Capsule (MAC) system, originally developed when Dr. Valdastri was at Scuola Superiore Sant’Anna.
The platform is composed by two main subsystems:
