Abstract:

The active endoscopy system has a locomotion system that allows the endoscopist to control the capsule's motion in the GI tract. The endoscopist can move, or stop the capsule at any targeted locations, which provides a better and more reliable diagnosis. We propose a novel design of a capsule's locomotor with shape memory alloy (SMA) actuators. The hinge mechanism to translates the linear movement of the SMA into a translational motion to the capsule's links. The proposed design has the added advantage of steering the capsule's camera system by activating one or more SMA wires. To the best of our knowledge, this is the first proposed active capsule that has a steering mechanism that controls the camera view angle at the top of the capsule. This camera's steering mechanism leads to a wider angle range for the system without adding to the capsule's weight and size. Also, this will help to better capture pathological areas without increasing power consumption. The proposed capsule prototype is manufactured using 3D printing technology and powered by a battery installed in the capsule.
