Description

Technical Field

[0001] The invention relates to the technical field of laser hair growth treatment hand tools, and in particular to a visible dot matrix laser hair growth treatment hand tool. Background Art

[0002] Hair loss has become a problem that troubles many people. In modern society, young and middle-aged people are under too much pressure, have irregular work and rest schedules, and lack exercise, which makes some hair loss problems gradually become younger. Androgenic alopecia and alopecia are the two main causes of hair loss. Some traditional drugs, such as minoxidil and finasteride, can treat androgenic alopecia, but they have great side effects, high recurrence rate, and poor patient tolerance.

[0003] Laser treatment for hair loss has been widely used in clinical practice. A large number of clinical trials and controlled trials have proved that laser can effectively treat androgenic alopecia and alopecia areata, and the treatment effect is very significant.

[0004] In the prior art, fractional laser treatment for hair loss usually cannot accurately control the specific location of laser treatment on the scalp. The laser treats the hair and scalp indiscriminately, and the existing hair will be damaged during the treatment. In addition, for patients whose hair is not very sparse, it is difficult to accurately determine the condition and location of the scalp that needs treatment by visual inspection. During the treatment, abscesses, blood scabs and other parts of the scalp that are not suitable for treatment cannot be effectively avoided, causing unnecessary secondary damage to the patient. Summary of the invention

[0005] To this end, the present invention provides a visible fractional laser hair growth treatment hand tool to solve the above-mentioned problems in the prior art.

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

[0008] Furthermore: the lighting module provides the image capture module with the ambient light required for capturing the treatment area. The emission band of the lighting module is the visible light region and the near-infrared region. The lighting module emits scattered light, covering the maximum viewing angle treatment area.

[0009] Furthermore: the optical material used in the transparent observation window area at the bottom of the optical waveguide array treatment head is a material with a visible light transmittance greater than 85%. The light emitted by the lighting module passes through the optical waveguide array treatment head to reach the scalp treatment area. The scalp treatment area reflects the light back to the image capture module, and the imaging information of the treatment area is displayed on the image display module.

[0010] Furthermore: a shell capable of installing a lighting module and an image capturing module is provided on the side of the hand tool body, the shell can be connected to the hand tool body, and the wiring harness in the shell is electrically connected to the electrical components in the hand tool body.

[0011] Further: The optical waveguide array treatment head is characterized in that the array point density ranges from 10 to 100 points / cm 2 The size range of single-point treatment head of optical waveguide treatment surface is 0.15~0.8mm, and the size range of dot matrix laser spot is 0.1~0.5mm.

[0012] Furthermore: the treatment selection display module can display the warning information given by the warning module, the selectable working points in the laser treatment area, and the working points that need to be avoided.

[0013] Further: the processing flow of the image processing module is:

[0014] The image processing module identifies the scalp surface features under the treatment head position;

[0015] The storage module on the main control board stores the above-mentioned target feature information picture;

[0016] The image processing module performs single-point segmentation on the scalp feature image at the treatment position of the treatment head;

[0017] The segmented single image is compared with the feature image in the storage module to identify the image feature information, determine the feature according to the target information, and indicate whether treatment is needed in the treatment selection display module;

[0018] After the features of all segmented images are identified, the information is given to the main control board. The main control board controls the working status of the galvanometer and the laser according to the identified features. When the galvanometer moves to a suitable treatment area, the laser state is on; when the galvanometer moves to an unsuitable treatment area, the laser state is off.

[0019] Further: the image processing module performs single-point segmentation based on the area below the corresponding single-point treatment head.

[0020] Further: when the single-point segmentation image cannot be compared to a feature target, a manual identification feature is selected and stored in a storage unit; the manual identification feature can be manually input and stored on the operation interface.

[0028] The following is an explanation of the implementation of the present invention by specific specific examples. People familiar with this technology can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. It should be understood that these embodiments are only to further illustrate the present invention and cannot be understood as limiting the scope of protection of the present invention. Technical engineers in this field can make some non-essential improvements and adjustments to the present invention based on the contents of the above invention; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] like Figure 1-5 As shown, a visible fractional laser hair growth treatment handpiece includes a handpiece body 1, an optical waveguide array treatment head 2, an illumination module 3, an image capture module 4 and a specific wavelength laser 5;

[0030] The hand tool body 1 is connected to an optical waveguide array treatment head 2 at the bottom, and a specific wavelength laser 5 is connected to the top. The lighting module 3 and the image capture module 4 are arranged on the side of the hand tool body 1, and the lighting direction of the lighting module 3 is toward the transparent observation window area at the bottom of the optical waveguide array treatment head 2. The image capture module 4 can observe the skin condition inside the optical waveguide array treatment head 2 through the transparent observation window area.

[0031] The lighting module 3 provides the image capture module 4 with the ambient light required for capturing the treatment area. The emission band of the lighting module 3 is in the visible light region and the near-infrared region. The lighting module 3 emits scattered light, covering the maximum viewing angle treatment area.

[0032] The optical material used in the transparent observation window area at the bottom of the optical waveguide array treatment head 2 is a material with a visible light transmittance greater than 85%. The light emitted by the lighting module 3 passes through the optical waveguide array treatment head 2 to reach the scalp treatment area, and the scalp treatment area reflects the light back to the image capture module 4, thereby displaying the imaging information of the treatment area on the image display module 14.

[0033] In this embodiment, in order to achieve a better real-time effect, a shell capable of installing a lighting module 3 and an image capture module 4 is provided on the side of the hand tool body 1. The shell can be connected to the hand tool body 1, and the wiring harness in the shell can be electrically connected to the electrical components in the hand tool body 1.

[0034] The handpiece body 1 is provided with an image recognition module 6, an image processing module 7, an image display module 14, an early warning module 8 and a main control board 11; the image capture module 4 is electrically connected to the image recognition module 6, and the image recognition module 6 is electrically connected to the image display module 14 and the image processing module 7; the early warning module 8 is electrically connected to the main control board 11, and the early warning module 8 is electrically connected to the image processing module 7; the image display module 14 can transmit images to the operation interface 9, and the operation interface 9 is electrically connected to the main control board 11; a treatment selection display module 10 is provided on the operation interface 9.

[0035] In addition, a storage module is electrically connected to the main control board 11 , and the storage module is electrically connected to the image processing module 7 .

[0036] Further: The optical waveguide array treatment head 2 is characterized in that the array point density ranges from 10 to 100 points / cm 2The diameter of the single-point treatment head of the optical waveguide treatment surface ranges from 0.15 to 0.8 mm, and the diameter of the dot matrix laser spot ranges from 0.1 to 0.5 mm.

[0037] After the image capture module 4 captures the image of the treatment area, the image recognition module 6 automatically identifies the specific position of the fractional laser of the optical waveguide array treatment head 2 and the pathological condition of the scalp at the corresponding position. The image processing module 7 identifies the scalp condition that is not suitable for treatment, and gives a warning message through the warning module 8 by comparing it with the position of the laser treatment point.

[0038] The corresponding specific situation is: when the equipment user fails to identify the avoidance working point, the warning module 8 gives a warning message, and the warning message is cancelled through the operation of the treatment selection display module 10.

[0039] The treatment selection display module 10 can display the warning information given by the warning module 8, the selectable working point 13 in the laser treatment area, and the working point 12 that needs to be avoided; the equipment operator can manually select and avoid the corresponding working point position.

[0040] like Figure 4 As shown, the purpose of the image processing module 7 is to identify the surface features of the scalp under the position of the treatment head, mainly the hair follicles of the treatment target body, and characteristic areas that are not suitable for treatment targets such as wounds, cysts, inflammation, etc.

[0041] The storage module on the main control board 11 stores the above-mentioned target feature information picture; the image processing module 7 performs single-point segmentation on the scalp feature picture at the treatment position of the treatment head;

[0042] The segmentation is based on the area below the corresponding single-point treatment head. For example, the size of the single-point treatment head is 0.5*0.5mm; the size of the image segmentation sheet is 1*1mm;

[0043] The segmented single image is compared with the characteristic image in the storage module to identify the characteristic information of the image, and whether the target information is judged to be a hair follicle or a cyst and other characteristics is marked in the treatment selection display module to indicate whether treatment is needed;

[0044] After the features of all segmented images are identified, the information is given to the main control board 11. The main control board 11 controls the working status of the galvanometer and the laser according to the identified features. When the galvanometer moves to a suitable treatment area, the laser state is on; when the galvanometer moves to an unsuitable treatment area, the laser state is off.

[0045] When the single-point segmentation image cannot be compared to a feature target, the feature can be manually identified and stored in the storage unit; manual identification can be performed on the operation interface 9 to manually input and store information.

[0046] The therapeutic handpiece of the present invention can monitor the specific conditions of the treatment area in real time during use; it can remind the equipment operator to avoid working points that are not suitable for treatment; for working points that the operator misjudged, the equipment gives an early warning, thereby reminding the operator to re-evaluate the treatment area.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
