Abstract

A depth limiting device includes a braking structure; a limited shrinking structure, the limited shrinking structure including a part that surrounds a moving object and being in a home position or a compressed position; and a structure adapted for pushing the limited shrinking structure to the home position. The braking structure brakes the moving object such that the moving object moves together with the depth limiting device. When the moving object enters into a subject, the part of the limited shrinking structure is pressed against the subject, and the limited shrinking structure moves from the home position to the compressed position and stops the moving object from entering further into the subject.
