Abstract
A depth limiting device includes an axial braking structure; a limited shrinking structure, the limited shrinking structure surrounding 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 axial braking structure axially brakes the moving object such that the moving object moves together with the depth limiting device, and when the moving object enters into a subject, the limited shrinking structure is pressed against the subject, moves from the home position to the compressed position, and stops the moving object from entering further into the subject.
Claims5
A depth limiting device, comprising:
- an axial braking structure;
- a limited shrinking structure, the limited shrinking structure surrounding 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,
- wherein the axial braking structure axially brakes the moving object such that the moving object moves together with the depth limiting device, and
- wherein when the moving object enters into a subject, the limited shrinking structure is pressed against the subject, moves from the home position to the compressed position, and stops the moving object from entering further into the subject.
