Outline of Final Research Achievements |
To realize a self-propelled catheter, we challenged to create a crawl type ultra-thin and flexible actuator that propels the blood vessel while generating a traveling wave.The introduced actuator consists of the inner tube and the Pneumatic artificial muscles:PAMs.Further, in the inner tube, holes having different sizes are provided so that each pressurizing chamber of the PAMs is pressurized at different timing.When fluid pressure is applied inside the inner tube, a propulsive motion is generated while propagating a traveling wave from the head to the root.We have constructed the design method of the proposed actuator, so that it could propel at an outer diameter of 4 mm and a speed of 10 mm / s. We also devised a reverse function and a direction steering function. Experiments confirmed the validity of these proposed methods.
