Towards a Magnetic Articulated Needle

Abstract:

In order to reach the deep of a human body, steerable needle is usually used in minimally invasive surgeries. For increasing the steerability and steering accuracy, a novel magnetic articulated needle is proposed in this paper. The proposed needle consists of a magnetic head, articulations, and sections. A magnetic force is generated on the needle head by adding an external magnetic field, which is used to manipulating the needle’s inserting path. The generated magnetic force and the motion of such a needle are analyzed for understanding the steering of the needle. The proposed needle is more easily to be controlled to avoid obstacles in human body while inserting.
