Specific embodiment
As shown in Figs. 1-5, catheter dredging brush includes microtubular 1 and seal wire 2 around property, the outer diameter of the microtubular 1 with
Urethral catheterization pipe orifice clearance fit, the seal wire 2 use metal material.Match in the internal orifice dimension gap of 2 diameter of seal wire and microtubular 1
It closes, the seal wire 2 is axially movably arranged in microtubular 1, and 2 front end of seal wire is equipped with cilium ball 3, and cilium ball 3 uses
The composition of fiber filament made of high molecular material manages interior tamper to be conducive to more efficiently remove, and reduces the stimulation to human body,
The cilium end of the cilium ball 3 is preferably barb-like, and the cilium end of the cilium ball 3 is preferably spheric.
In order to which the movement for being accurately controlled seal wire 2 can be compared, and then it is accurately controlled the position of cilium ball 3, as this
The further setting of invention, is preferably provided with 2 driving mechanism of seal wire in the tail end of the microtubular 1.2 driving mechanism of seal wire
Specific setting can be the tail end in the microtubular 1 equipped with a bit of screwed pipe 4, and 2 tail end of seal wire is equipped with one section of matching
Stud 5 is adjusted, the cooperation of adjusting stud 5 constitutes 2 driving mechanism of seal wire in the screwed pipe 4；Either described micro-
