Abstract

The invention provides a laser-induced thermotherapy device and system based on magnetic resonance guidance. The device comprises a work station, laser ablation equipment and a minimally invasive operation optical fiber module; the work station is used for generating an operation plan according to the pre-operation focus digital image of a patient, sending the operation plan to the laser ablationequipment, generating a real-time temperature image of the focus region by using the magnetic resonance temperature imaging technology in the operation, and controlling the laser power and the coolingpower in real time through the temperature numerical values of the focus and the peripheral health tissue; the laser ablation equipment is used for producing and regulating the laser, driving and controlling the circulation of the cooling mesenchyme; the minimally invasive operation optical fiber module performs precise conformal ablation on the regular or irregular tumor in the disease treatmentby using the laser and the cooling mesenchyme and cools the operation optical fiber module and the peripheral tissue. The regular or irregular tumor can be effectively ablated, and the ablation boundary can be real-time adjusted in the operation through the nuclear magnetism temperature imaging, thereby achieving the conformal ablation aim.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a laser thermal therapy device and system based on magnetic resonance guidance. Background technique [0002] In the treatment of focal epilepsy in the brain, malignant tumors (which cannot be solved by radiotherapy), and gangrene after radiotherapy, it is difficult for the existing hyperthermia technology to accurately treat deep lesions and irregular lesions. Accurately ablate the lesion while protecting the surrounding normal tissues to the greatest extent. Moreover, it is relatively difficult to achieve MR compatibility, and MR (Magneticresonance, magnetic resonance) temperature imaging cannot be used for accurate assistance. [0003] The objective shortcoming of the prior art mainly lies in that it is difficult to achieve precise conformal ablation in radiofrequency ablation. At present, it is necessary to plan the treatment parameters before implementing radiofr...
