Abstract
Present invention is a tip adjustable stylet to be inserted into a tubular structure and to be pushed out its distal aperture to form curvatures. The device comprises a bendable member, a retracting string, an intersegment and a control handle. The bendable member has a control ring at its proximal end and a tip at its distal end. An operator can push the bendable member distally from the proximal end along the lumen of the tubular structure. Predetermined extensibility and length of the retracing string limit distance of the bendable member being pushed and hold the distal portion of the bendable member backward when the bendable member is been pushed forward outside of the tubular structure's distal aperture, thereby to bend the distal portion of the bendable member into the curves therefore to move its tip to a target location, such as patient's vocal cords opening.
