Perfusion basket ultrasonic ablation catheter

The invention discloses a perfusion basket ultrasonic ablation catheter which comprises a multi-cavity tube, the near end of a perfusion basket support is fixed to a far-end inner cavity of the multi-cavity tube, the perfusion basket support is communicated with a liquid channel in the multi-cavity tube, and a plurality of water spraying holes are formed in the surface of the perfusion basket support. Under the condition that the mesh basket support is initially opened, the water spraying holes spray normal saline towards the energy converter located in the middle of the filling mesh basket support to clean the surface of the energy converter, and the center wire is connected with the multi-cavity tube and used for fixing the energy converter and the far end of the filling mesh basket support. The mesh basket supporting wires are hollow porous wires, normal saline can be infused through the porous wires and directly sprayed to the surface of the transducer, the surface temperature of the transducer is reduced
