Example Embodiment

[0134] Example 1: About accurate temperature measurement design.

[0135] Please refer to figure 2 Based on the multi-wave multi-channel laser system described above, the embodiment is improved, and the multi-wave multi-channel laser system has both the temperature measurement function of the magnetic resonance guide, and also has real-time detection tissue. The function of the temperature can achieve double precision temperature measurement. Specifically, the fiber catheter 31 and the fiber catheter 222 have the same structure, where the fiber catheter is taken as an example: a temperature measurement fiber is provided on the optical fiber conduit 301, and the temperature measurement is provided. The connection relationship between the optical fiber 8 and the optical fiber conduit 31 includes, but is not limited to, adhesion, embedding setting, and the like. Preferably, the detection temperature of the temperature measurement fiber 8 is adjacent to the light light portion 9 of th...

[0140] Example 2: Optimization Scheme of System Temperature Control Design.

[0141] like image 3 As shown, in order to further improve the accuracy of the suitable ablation, the laser module 202 is also configured with a cooling module, which is connected to the control host 201, and the optical fiber. The catheter unit 300 is connected. The control host 201 controls the operation of the cooling module; the cooling module is cooled by tissue of the fiber catheter unit 300 and the fiber catheter unit 300 by driving and controlling the circulation flow of the cooling medium. The optical fiber catheter unit 300 has the same structure, and the fiber catheter 2 302 is described in the optical fiber catheter 21, which is described in the optical fiber conduit 301: the fiber catheter 301 contains optical fibers, cooling inner tubes and cooling. Tube. The optical fiber is connected to the laser device 1221; the optical fiber, the cooling inner tube and the cooling medium composed of the ...

Example Embodiment

[0149] Example 3: Optimization Scheme 2 for system temperature control design.

[0150] See Figure 4 Compared with the second embodiment, the difference between the embodiment three is only that the optical fiber catheter 31 and the fiber catheter 2 302 share a cooling module, a shared form or method, and those skilled in the art can be obtained according to the prior art, once again Do not done.

Abstract

The invention provides a multi-wavelength multi-channel laser system for thermal ablation in the neurosurgery department. The multi-wavelength multi-channel laser system comprises a magnetic resonance guiding unit, a laser ablation unit and an optical fiber catheter unit, wherein the laser ablation unit is used for generating an operation path and an operation scheme before an operation and regulating and controlling multiple laser modules and cooling modules in real time during the operation to achieve precise ablation of tissue, and the optical fiber catheter unit is provided with multiple ablation channels and can achieve ablation of tumors of any scale. According to the invention, a multi-wavelength multi-channel treatment scheme can be adopted, and a high-power single-wavelength single-channel scheme can be used for performing accurate conformal ablation on regular or irregular tumors, so that the application range and the use flexibility of laser thermal therapy are greatly improved.

Description

technical field [0001] The invention belongs to the field of laser treatment, in particular to a multi-wavelength and multi-channel laser system for thermal ablation in neurosurgery. Background technique [0002] Laser medical technology is to irradiate the laser emitted by the laser on the tissue to be treated through the medical optical fiber, and use the thermal effect or shock wave generated by the laser to perform thermal coagulation, vaporization or cutting treatment of lithotripsy or soft tissue. Laser medical technology is widely used in the treatment of thermal damage to cells, lithotripsy, and soft tissue cutting due to its short operation time and small wounds. In recent years, laser interstitial thermal therapy (LITT) guided by magnetic resonance imaging (MRI) has attracted the attention of domestic and foreign medical workers. Therapy, hereinafter referred to as LITT) is the application of the principle of thermal effect of laser. The laser interstitial hypert...
