First claim

What is claimed is:

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.

2. The catheter or guide wire manipulating device according to claim 1 , wherein the catheter or guide wire manipulating device is configured to manipulate the catheter/guide wire to implement advancement motion and rotation motion along two directions; the advancement motion of catheter/guide wire is attached to the rotation motion of the catheter/guide wire.

3. The catheter or guide wire manipulating device according to claim 1 , wherein, the thumb component includes a roller, a rubber cover, a drive shaft, a bearing unit, a motor frame, a coupling and an advancing motor; the advancing motor is fixed to the motor frame with bolts; a motor output shaft of the advancing motor is connected to the drive shaft by a coupling; the drive shaft is supported by the bearing unit; ends of the drive shaft are connected to the roller by a thread; the rubber cover is made of material of rubber and mounted on the roller by an interference fit.

4. The catheter or guide wire manipulating device according to claim 3 , wherein, the roller of the thumb component is configured to rotate to make the catheter/guide wire advance or retreat by making the drive shaft rotate through the coupling, driving the roller of the thumb component to rotate by a rotation of the advancing motor output shaft and driving the catheter/guide wire to be advanced or retreated with the spring's pull force between the rubber cover of the thumb component and the rubber cover of the forefinger component.

5. The catheter or guide wire manipulating device according to claim 4 , wherein the catheter/guide wire is configured to rotate clockwise or counterclockwise via a combined motion of the thumb component and forefinger component by connecting the roller, the rubber cover, the drive shaft, the bearing unit, the motor frame, the coupling, and the advancing motor of the thumb component as a whole part to the driving component through a connecting plate, moving the whole part linearly up and down with a guidance of guide rails, while driving the roller of forefinger component by the driving component to move linearly in an opposite direction to a motion direction of the whole part.

6. The catheter or guide wire manipulating device according to claim 5 , wherein the forefinger component includes a roller, a rubber cover, a roller shaft, a bearing unit, a forefinger component pedestal, a spring, a horizontal guide rail, a forefinger component base board, a vertical guide rail and a connecting plate; the rubber cover is fixed to the roller by an interference fit; the roller is connected fixedly to the roller shaft through a thread; the roller shaft is supported fixedly by the bearing unit fixed on the forefinger component base board by the guide rail; the forefinger component base board is connected to a screw rod output through the connecting plate and to a fixed pedestal of the driving component through the guide rails; the forefinger component pedestal is configured to tightly press the roller of the forefinger component and the roller of the thumb component through a pull force of a spring.
