[0044] The embodiment of the present application provides a laser diagnostic device based on spatial multi-focus, which has a compact structure and is easy to operate. In particular, it can perform real-time online diagnosis of in vivo tissues in a limited space, thereby improving the laser diagnostic effect.

[0045] refer to Figure 1 As shown, Figure 1 The present invention is a schematic structural diagram of a laser diagnostic device based on spatial multi-focus according to an embodiment, comprising: a diagnostic laser module 11, an optical deflection module 12, a fiber coupling module 13, a fiber array 14 and a focusing microlens array 15 which are sequentially connected through an optical path; wherein the fiber coupling module 13 is independently connected to each fiber branch in the fiber array 14, and each fiber branch is connected to a focusing microlens in the focusing microlens array 15. The fiber branches of the fiber array 14 can be arranged in rows and columns, such as an n×n layout, and the fiber array 14 can set the length of the optical fiber according to the transmission distance.

[0046] During diagnosis, the diagnostic laser module 11 emits a diagnostic laser, which enters the optical deflection module 12. The optical deflection module 12 deflects the beam of the diagnostic laser at a specific angle. The optical fiber coupling module 13 couples the diagnostic laser into a target optical fiber branch in the optical fiber array 14 and transmits it to the focusing microlens array 15. Then, the focusing microlens of the focusing microlens array 15 focuses the diagnostic laser on the diseased tissue 01, generates a laser signal with tissue characteristic information, and uses the laser signal diagnosis to obtain the corresponding biological tissue information of the diseased tissue 01. Since each focusing microlens can be focused on a focus in space, each optical fiber branch corresponds to a focusing microlens in the focusing microlens array 15. After each optical fiber branch is transmitted once, a laser diagnosis can be performed at the focal position of each focusing microlens of the focusing microlens array 15, so that a refined diagnosis of the diseased tissue 01 can be performed, and more accurate biological tissue information of the diseased tissue 01 can be obtained.

[0047] In one embodiment, reference Figure 2 As shown, Figure 2 It is a structural schematic diagram of a laser diagnostic device based on spatial multi-focus of another embodiment, which may also include a controller 20, and the controller 20 is connected to the diagnostic laser module 11 and the light deflection module 12; wherein the controller 20 is used to control the diagnostic laser module 11 to output a diagnostic laser with set parameters, and control the light deflection module 12 to deflect the diagnostic laser in turn by a specific angle, so as to couple the diagnostic laser in turn to a target optical fiber branch of the optical fiber array 14.

[0048] Specifically, the diagnostic laser module 11 has a built-in laser light source, which can emit laser pulses with specific parameters under control. The optical deflection module 12 can have a built-in deflection component. For the optical deflection module 12 and the optical fiber coupling module 13, exemplarily, the optical deflection module 12 can use an acousto-optic deflector or a galvanometer, and the optical fiber coupling module 13 can use a microlens array or a common lens group.

[0049] like Figure 3 As shown, Figure 3 It is a schematic diagram of the structure of an example fiber coupling module. In order to achieve higher coupling efficiency, an arc shape is set on the fiber coupling module 13 according to the distance between the light deflection module 12 and the fiber coupling module 13, and the end face of each fiber branch is set perpendicular to the laser incident direction. Therefore, after the light deflection module 12 deflects the diagnostic laser, it is vertically incident on the fiber branch, thereby improving the laser transmission efficiency and ensuring the accuracy of laser diagnosis.

[0050] In one embodiment, in the laser diagnostic device based on spatial multi-focus of the present application, the focusing microlens array 15 also collects the laser signal generated by the diagnostic laser irradiating the diseased tissue 01, and transmits the laser signal to the fiber coupling module 13 through the target fiber branch. The fiber coupling module 13 transmits the laser signal to the light deflection module 12, and the light deflection module 12 returns the laser signal to the diagnostic laser module 11. The diagnostic laser module 11 separates the laser signal from the optical path and analyzes it; for separating the laser signal, a dichroic mirror can be used to separate the diagnostic laser and the returned laser signal in the optical path. Further, after obtaining the laser signal, the diagnostic laser module 11 can analyze the characteristic parameters of the laser signal and send it to the controller 20. The controller 20 can calculate the biological tissue information of the entire diseased tissue 01 based on the characteristic parameters of the laser signal returned by the branch optical fiber corresponding to each position point.

[0051] In one embodiment, when the controller 20 controls the diagnostic laser module 11 to perform diagnosis, it first controls the optical deflection module 12 to couple the diagnostic laser deflection setting angle into one of the branch optical fibers, and then controls the diagnostic laser module 11 to emit the diagnostic laser and obtain the returned laser signal, and calculates the biological tissue information of the diseased tissue 01 at the corresponding position point of the corresponding branch optical fiber; after completing this acquisition, the controller 20 will control the optical deflection module 12 to deflect the diagnostic laser by another angle, so that the diagnostic laser is coupled into another specific optical fiber branch, and the returned laser signal is obtained again to analyze and calculate the biological tissue information of the corresponding position point; and so on, after completing this acquisition, it will deflect by another angle, and the operation will be repeated until all the position points of the diseased tissue 01 corresponding to all optical fiber branches are calculated.

[0052] refer to Figure 4 As shown, Figure 4This is an example of the coding diagram of the deflection angle and the light output point position; the light spot position of each branch optical fiber is encoded, and each light spot position corresponds to a deflection angle θ, and the deflection angle θ is a spatial angle. Thus, n optical fibers can form deflection angles θ1~θ n For example, when n=5×5, the deflection angles θ1~θ 25 , which can correspond to branch optical fibers coded 1 to 25 respectively; as shown in the figure, the branch optical fibers start from code 1 to code 25, and the controller 20 rotates according to the deflection angles θ1 to θ 25 Deflection is performed in sequence to couple the diagnostic laser to each optical fiber branch of the optical fiber array 14, and the focusing microlens array 15 focuses the diagnostic laser onto the diseased tissue 01, generating a laser signal with tissue characteristic information, which returns along the original path to the diagnostic laser module 11 for parameter characteristic analysis, and the signal characteristic parameters are sent to the controller 20 to obtain the corresponding biological tissue information at the focus of the branch optical fiber, mainly the material structure information; after all position points are collected, the biological tissue information collected by each branch optical fiber is used to form a scanned image of the diseased tissue 01 for pathological diagnosis, which can be compared with the database to obtain the biological tissue information of the entire diseased tissue 01, which can be used for rapid and accurate pathological diagnosis of the diseased tissue, thereby improving the diagnostic efficiency, reducing harm to patients and alleviating pain.

[0053] The spatial multi-focus laser diagnostic device, as exemplified above, has a compact structure and is easy to operate. It can perform detailed diagnosis of diseased tissues, and is particularly useful for real-time online diagnosis of in vivo tissues in limited spaces, thereby providing an important reference for the treatment of diseased tissues.

[0055] When used for diagnosis, the optical path switching module 40 is connected to the diagnostic laser module 11, the diagnostic laser module 11 emits the diagnostic laser, the optical path switching module 40 receives the diagnostic laser and outputs it to the optical deflection module 12, the optical deflection module 12 couples the diagnostic laser to a fiber branch of the optical fiber array 14, and transmits it to the focusing microlens array 15, and finally focuses on the diseased tissue 01 for diagnosis.

[0056] When used for treatment, the optical path switching module 40 is connected to the treatment laser system 30, the treatment laser system 30 emits the treatment laser, the optical path switching module 40 receives the treatment laser and outputs it to the optical deflection module 12; the optical deflection module 12 couples the treatment laser to a fiber branch of the optical fiber array 14, transmits it to the focusing microlens array 15, and finally focuses on the diseased tissue 01 for ablation treatment.

[0057] In one embodiment, the therapeutic laser system 30 and the optical path switching module 40 are also respectively connected to the controller 20; the controller 20 controls the therapeutic laser system 30 to emit a therapeutic laser of a set power, and controls the optical path switching module 40 to switch to connect to the diagnostic laser module 11 or the therapeutic laser system 30.

For example, during ablation treatment, the controller 20 controls the treatment laser module 31 to emit a treatment laser with set parameters, and the optical modulation module 32 performs independent power regulation on the treatment laser. The optical modulation module 32 may include a spatial light modulator, an optical fiber acousto-optic modulator, etc.; the optical fiber coupling module 13 may couple the treatment laser for ablation treatment of each different lesion location point into each optical fiber branch in the optical fiber array 14 in sequence, and the focusing microlens array 15 spatially focuses the treatment laser to the lesion location point corresponding to the diseased tissue 01 for ablation treatment.

[0060] Specifically, the therapeutic laser for ablation at each location point can be switched on and off and the power can be adjusted by the optical modulation module 32. The optical deflection module 12 can deflect it to the optical fiber coupling module 13 and couple it to the optical fiber branch of the optical fiber array 14 according to the current location point of the ablation treatment using the biological tissue information obtained in advance. The optical fiber array 14 transmits each optical fiber branch to the focusing microlens array 15. The therapeutic laser of each optical fiber branch can be independently controlled and spatially focused on each lesion location point of the diseased tissue 01 for ablation treatment.
