WIPO Patent Application WO/2017/150764
Kind Code:
A1
Abstract:
The present invention relates to a calculus removing device used in medical fields and, more particularly, to a calculus removing device having a calculus crushing probe, which can simultaneously crush and remove a calculus formed inside a human body selectively using a drawing force or electricity through the calculus crushing probe, regardless of the size of the calculus. A calculus removing device according to an aspect of the present invention may comprise: a first tube having an inner space formed therein; a second tube inserted into the inner space of the first tube so as to move inside the inner tube; a capturing means having an end coupled to an end of the second tube such that the capturing means is introduced into the inner space of the first tube in response to a movement of the second tube, thereby capturing and retaining a calculus; a calculus crushing probe inserted into the inner space of the second tube so as to contact the calculus, which is retained by the capturing means, and to apply an electric impact thereto; and a handle coupled to an end of the first tube so as to independently move the second tube and the calculus crushing probe.
