Claim:
1. A catheter or guide wire manipulating device for vascular intervention comprising a thumb component, a forefinger component, a driving component and a catheter/guide wire support component; the thumb component comprises a roller configured to advance or retreat the catheter/guide wire; the thumb component is configured to drive the catheter/guide wire to rotate clockwise or counterclockwise by a combination motion of the thumb component and the forefinger component; the forefinger component is configured to cooperate with the thumb component to implement the rotation and advancement of the catheter/guide wire by moving the forefinger component manually away from the thumb component, and the forefinger component returning by a pull force of a spring after being released; the driving component is configured to drive the thumb component and the forefinger component; the driving component include a rotating motor, gears, pinions and screw rods, the rotating motor drives gears to rotate, the gears are engaged with the pinion correspondingly, nuts of the screw rods make a linear movement along opposite directions so that the linear movement is supplied to the thumb component and the forefinger component, respectively; the catheter/guide wire support component comprises a Y adapter fixation configured to install a Y adapter and an entry support configured to support and guide the catheter/guide wire into a mechanism; the entry support has a hollow structure to support the catheter/guide wire when the catheter/guide wire is transmitted into the mechanism; wherein rollers of the forefinger and thumb component are provided with rubber covers respectively so that a deformation is formed on the rubber cover as the two components are tightly pressed by the proper pull force of the spring and a contact area between rubber covers and the catheter/guide wire is increased, improving a stability of manipulating the catheter/guide wire via a friction.
