The invention belongs to the field of interventional surgery robots, and in particular relates to a main-end control device for vascular interventional surgery robots, which includes a surgical control ring, a force-sensing control mechanism, a position detection mechanism and a rotation detection mechanism. The force-sensing control mechanism includes a torque generator, a synchronous Pulley, synchronous idler wheel and synchronous belt, the position detection mechanism includes a magnetic ring guide shaft and a displacement sensor for detecting the position of the surgical control ring on the magnetic ring guide shaft; the rotation detection mechanism is connected with the synchronous belt, and is also connected with the surgical control ring Turn to connect. Based on the present invention, firstly, when the doctor manipulates the surgical control ring, the force feedback can be effectively obtained; secondly, the rotation and pushing actions of the guide wire / catheter can be performed together, and the rotation angle is not limited, which reduces the complexity of the surgical operation; finally , in line with the doctor's habit of operating the guide wire / catheter with two fingers in routine operations for interventional surgery, which reduces the difficulty for doctors to learn robot operation.
