4 4 AN END-ANGLE-CONTROLLED CATHETER DEVICE USING FOUR GUIDE LINES IN FOUR DIRECTIONS OF UP AND DOWN AND LEFT AND RIGHT DIRECTIONS AND A METHOD OF USING THE SAME

摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a catheter apparatus for adjusting an end angle using four guide lines in four directions of upper, lower, left, and right directions, and more specifically, a catheter apparatus having an elongated flexible tube, Four wires arranged at intervals of 90 [deg.] Apart, one end being guided to the distal end of the catheter body, one end of the four guidewires being spaced at 90 [deg.] From the distal end of the catheter body And four inlet holes which are arranged at a position shifted by a predetermined distance in the direction of the catheter body from the fixed portion at the distal end of the catheter body to draw the four guide lines into the inside of the catheter body By adjusting the lengths of the four guide lines drawn to the distal end of the catheter body, And to control a feature of the configuration thereof. The present invention also relates to a method of using an end angle-adjustable catheter apparatus using four guide lines in four directions of upper, lower, left, and right directions, more specifically, as a tube having flexibility of elongated shape, , Four wires arranged at intervals of 90 [deg.] From each other, one end of the four lead wires arranged at 90 [deg.] Apart from each other at the distal end of the catheter body to which the other end is led to the distal end of the catheter body And four inlet holes for introducing the four guide lines into the interior of the catheter body, which are disposed at a position shifted from the fixed portion at the end of the catheter body by a predetermined distance in the direction of the distal end of the catheter body A method of using a catheter device comprising: (1) a catheter body, which is a flexible elongated tube, And (2) adjusting the distal angle of the catheter body by adjusting the lengths of the four guide lines extended to the distal end of the catheter body. According to the end angle-controlled catheter apparatus using the four guide lines in the four directions of up and down and left and right as proposed in the present invention, the catheter body inserted into the inside of the body is composed of four wires arranged at intervals of 90 degrees, A guide wire extending from the distal end of the catheter body to the distal end of the catheter body, four fixed portions of which one end of the four guide wires are fixed, and a fixed portion of the distal end of the catheter body, The catheter body includes four inlet holes for introducing the four guide lines into the interior of the catheter body. Thus, it is possible to replace the catheter or to rotate the catheter body in order to enter the target vessel , Simply adjusting the length of the four guide lines drawn to the distal end of the catheter body makes it easier to tilt the distal end of the catheter body vertically and horizontally Can be adjusted. In addition, according to the present invention, the catheter body further includes four guide portions at the distal end thereof, so that it is possible to easily grasp the direction in which the angled end of the catheter body is directed when adjusting the direction of the distal end of the catheter body, It is possible to prevent the four guide lines from being tangled to each other inside the tip of the catheter body, and the four guide lines drawn out from the guide portion can be guided into the catheter body, Since there is no risk of crossing inside the body, the angle of the distal end of the catheter body can be adjusted in the direction in which the guide portion is disposed. In addition, according to the present invention, it is possible to solve the problem of reusing a catheter in a medical facility by constituting a relatively inexpensive catheter having a simple structure, unlike an expensive catheter having a conventional complicated structure, The risk of car infections can be reduced.
