Radio frequency ablation catheter having function of moving guide wire

A radiofrequency ablation catheter having a movable guide wire, comprising an electrode bracket, a catheter body and a control handle which are arranged in sequence, wherein

• the catheter body has a lumen for the movable guide wire sliding therein;
• the movable guide wire comprises a guide wire body and a soft guide wire at a distal end of the guide wire body and the soft guide wire being maintained outside the distal end of the electrode bracket;
• the movable guide wire has a first stop point, which is limited outside the distal end of the electrode bracket, and the first stop point is used to expand the electrode bracket;
• and the movable guide wire has a second stop point limited between the distal end of the electrode bracket and a proximal end of the electrode bracket, and being used for contracting the electrode bracket;
• the movable guide wire extends from the control handle, through the catheter body to the electrode bracket, with a distal end thereof outside the electrode bracket;
• the movable guide wire is controlled by a controlling member in the control handle or outside the control handle;
• the electrode bracket is changeable between a compact state and an expanded state, and is provided with a plurality of electrodes for radiofrequency ablation.
