Coronary artery rotational atherectomy intervention system

A coronary artery rotational atherectomy intervention system, comprising a rotational atherectomy mechanism, a physiological saline infusion system, a drive and control system, and a guide wire clamping system, wherein

• the rotational atherectomy mechanism comprises a guide wire, a drive shaft assembly, and a rotational atherectomy head,
• wherein
• the guide wire clamping system comprises a limit switch and a limit switch state detection and transmission module, the limit switch is connected to the limit switch state detection and transmission module, and after the guide wire is clamped, the limit switch is triggered to be in a closed state and is detected by the limit switch state detection and transmission module;
• the physiological saline infusion system comprises an infusion pump, an infusion pump control element, and an infusion pump state detection and transmission module, the infusion pump control element is connected to the infusion pump, the infusion pump control element is configured to control the infusion pump to be in a started state, and the infusion pump is connected to the infusion pump state detection and transmission module, to enable the started state of the infusion pump to be detected by the infusion pump state detection and transmission module;
• the drive and control system comprises a drive motor and a controller module, and the limit switch state detection and transmission module and the infusion pump state detection and transmission module are separately connected to the controller module to transmit state data to the controller module;
• and
• the controller module confirms, before issuing an instruction for starting the drive motor, that the infusion pump of the physiological saline infusion system is in the started state and the limit switch is in the closed state, to cause the drive motor to rotate and then drive the rotational atherectomy head to rotate together through the drive shaft assembly.
