Magnetic resonance guided laser ablation treatment system

A magnetic resonance guided laser ablation treatment system, comprising:

• an optical fiber cooling assembly, accommodating and cooling an ablation optical fiber;
• a laser ablation apparatus, comprising a laser generator and a cooling device;
• a stereotactic driving system, accommodating and controlling a position and/or a rotation angle of the ablation optical fiber;
• and a workstation, configured to:
• control the movement of the stereotactic driving system, and generate and display ablation information of the target region during the workflow of the magnetic resonance guided laser ablation treatment system by using magnetic resonance temperature imaging technology;
• wherein the stereotactic driving system comprises:
• a guiding device, comprising a cooling sleeve guide part and a guiding device shell;
• at least two sensor assemblies, each comprising an angle sensor;
• a rotation driving device and an axial movement driving device, the rotation driving device drives the ablation optical fiber to rotate and the axial movement driving device drives the ablation optical fiber along the major axis;
• and a controller, being connected in communication with the sensor assemblies and the rotation driving device, receiving output angle information from the sensor assemblies, controlling the movement of the rotation driving device and further receiving control information;
• wherein in a use state, the far end of the ablation optical fiber is arranged within the inside lumen of the optical fiber cooling assembly, the angle sensors are securely connected to a device or a structure which does not rotate together with the ablation optical fiber;
• wherein the stereotactic driving system further comprises a sleeve, the sleeve ensures that the length between the first sensor assembly and the second sensor assembly remains secure, and allows the ablation optical fiber to rotate about its major axis and move along the major axis in the sleeve.
