Embodiment 1

[0134] Example 1: An optimization scheme for precise temperature measurement design.

[0135] Please also refer to figure 2 , on the basis of the multi-wavelength multi-channel laser system described above, the improvement of the first embodiment is that the multi-wavelength multi-channel laser system not only has the temperature measurement function of the magnetic resonance guidance unit, but also has the function of real-time detection of tissue The temperature function can realize double precision temperature measurement. Specifically, the first optical fiber conduit 301 and the second optical fiber conduit 302 have the same structure, and here we take the first optical fiber conduit 301 as an example for illustration: the first optical fiber conduit 301 is provided with a temperature-measuring optical fiber, and the temperature-measuring The connection relationship between the optical fiber 8 and the first optical fiber guide 301 includes but not limited to adhesion, em...

Embodiment 2

[0140] Embodiment 2: Optimization scheme 1 about system temperature control design.

[0141] Such as image 3 As shown, in order to further improve the accuracy of conformal ablation, on the basis of Embodiment 1, the laser module 202 is also equipped with a cooling module, which is connected to the control host 201 and connected to the optical fiber The catheter unit 300 is connected. The control host 201 controls the operation of the cooling module; the cooling module cools the optical fiber catheter unit 300 and surrounding tissues of the optical fiber catheter unit 300 by driving and controlling the circulating flow of cooling medium. The optical fiber conduit unit 300 has the first optical fiber conduit 301 and the second optical fiber conduit 302 with the same structure. The first optical fiber conduit 301 is used for illustration: the first optical fiber conduit 301 includes an optical fiber, a cooling inner tube and a cooling outer tube. Tube. The optical fiber is c...

Embodiment 3

[0149] Embodiment 3: Optimization scheme 2 regarding system temperature control design.

[0150] see Figure 4 , compared with Embodiment 2, the difference of Embodiment 3 is only that the first optical fiber conduit 301 and the second optical fiber conduit 302 share a cooling module, and the common form or method can be obtained by those skilled in the art according to the prior art, again I won't go into details.

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...
