Title: Device for removing blood clots in the form of a 3D noose
Inventor: SEO JUNG HWA
IPC: A61B17/3205
Filed: 2021-03-26
Abstract: The present invention provides a 3D noose-type device for removing blood clots which comprises: a catheter with a hollow hole inside; an adjustment wire provided in the hollow hole of the catheter and selectively moving along the hollow hole; a first noose, one part of which is connected to a top end of the adjustment wire, and which unfolds in a ring shape while being bent at a corresponding angle when appearing outside the top end of the catheter due to the movement of the adjustment wire; and a second noose connected to a width direction side of the first noose and unfolding in an arc shape while being bent in a direction opposite to the bent direction of the first noose when appearing outside the top end of the catheter due to the movement of the adjustment wire. The 3D noose-type device for removing blood clots can be easily accommodated in the hollow hole of the catheter as the width of the noose which captures the blood clots is reduced and can form a smaller diameter of the catheter than before so as to easily enter the blood vessel which is difficult for the conventional device for removing blood clots to enter. In addition, the 3D noose-type device for removing blood clots can capture and remove the blood clots more easily due to a structural feature which the noose unfolds while being bent toward a wall side of the blood vessel at the same time as the noose appears at the top end of the catheter and enables the noose to enter and exit the top end of the catheter such that the width of the noose is selectively reduced and expanded so as to prevent the blood clots from being missed or fragmented during the blood clot removal.
