[0027] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and embodiments.

[0028] Example 1

[0029] See also Figure 1 A side view of a treatment head shown in FIG. Figure 2 The outer side of the treatment head body is shown in FIG. Figure 3 The inner side schematic diagram of the treatment head body shown in FIG. Figure 4 The schematic diagram shown is a diagram of the position where the light spot is formed on the front surface of the light guide device array. The present application proposes a treatment head, including: a treatment head body 100 and a laser handpiece bracket 200.

[0030] The treatment head body 100 is detachably connected to the laser handpiece bracket 200 .

[0031] The treatment head body 100 includes a light guide device array 101 , a micro lens array 102 and a hollow shell 104 .

[0032] The microlens array 102 is fixed on the hollow housing 104 , and the light guide device array 101 is arranged on the outer surface of the light side of the microlens array 102 .

[0033] The microlens array 102 includes: a plurality of microlenses arranged side by side; the light guide device array 101 includes: a plurality of light guide devices arranged side by side; wherein, the plurality of light guide devices can be in contact with the user's scalp.

[0034] Here, the density of the light guide device can be in the range of 30 / cm for the treatment of fractional laser. 2Up to 300 / cm 2 The plurality of microlenses are all microlenses with positive optical power.

[0035] The light guide device adopts a tapered optical device, which includes: a light guide cone and a tapered optical waveguide; the specific shape of the tapered optical waveguide is as follows Figure 4 shown.

[0036] In one embodiment, the height of the light guide cone and the tapered light waveguide are both between 3 mm and 5 mm.

[0037] The shape of the microlens array 102 is circular, square, or polygonal; correspondingly, the shape of the light guide device array 101 is also circular, square, or polygonal.

[0038] Each microlens in the plurality of microlenses and each light guide device in the plurality of light guide devices are arranged in the same manner, and each microlens corresponds to each light guide device one by one.

[0039] In one embodiment, the arrangement of each microlens in the plurality of microlenses and each light guide device in the plurality of light guide devices includes, but is not limited to, a single row arrangement, a multi-row arrangement, and a honeycomb arrangement.

[0040] Each of the microlenses converges the incident light beam, and the converged light beam is incident on the light guide device corresponding to the incident microlens, forming a light spot on the front surface of the light guide device array, wherein the front surface of the light guide device array is located on the light output side of the light guide device array.

[0041] In one embodiment, the light beam may be, but is not limited to, a laser beam in the visible light band and a laser beam in the near-infrared band; the wavelength of the light beam ranges from 400 nanometers to 2000 nanometers.

[0042] In order to enable the treatment head body 100 to be detachably connected to the laser handpiece bracket 200 , the treatment head proposed in this embodiment further includes a limiting rubber ring 103 .

[0043] The laser hand tool support 200 is provided with an interface, and a fixing rubber ring 201 is provided on the interface.

[0044] The limiting rubber ring 103 is fixed to the inner side wall of the hollow shell 104. The limiting rubber ring 103 fixed to the inner side wall of the hollow shell 104 is connected to the fixing rubber ring 201 provided on the laser handpiece bracket, so that the treatment head body 100 and the laser handpiece bracket 200 are detachably connected.

[0045] The position-limiting rubber ring 103 on the treatment head body 100 works in conjunction with the fixed rubber ring 201 at the interface of the laser handpiece support 200 to ensure the fixed and sealed position of the treatment head body 100 when assembled on the laser handpiece support 200, as well as the detachable connection between the treatment head body 100 and the laser handpiece support 200. The treatment head body 100 and the laser handpiece support 200 do not require additional tools during assembly, making replacement easy and eliminating the need to recalibrate the laser position and energy.

[0046] This embodiment also provides a hair growth treatment device, including: a fractional laser and the above-mentioned treatment head.

[0047] The fractional laser is fixed on a side of the laser handpiece support 200 in the treatment head away from the treatment head body 100 .

[0048] The dot matrix laser includes a laser module and a scanning galvanometer.

[0049] Here, the hollow shell 104 is used to fix the distance between the light guide device and the scanning galvanometer, ensuring that the focal plane of the assembled fractional laser can be at the designed position, that is, the treatment surface of the system, located on the front surface of the light guide device array.

[0050] The light beam emitted by the laser module is incident on the scanning galvanometer, and the scanning galvanometer reflects the incident light beam to each of the microlenses in the treatment head body 100 of the treatment head, so that each of the microlenses converges the incident light beam. The converged light beam is incident on the light guide device corresponding to the incident microlens, and together with other light beams incident on the light guide device, forms a light spot on the front surface of the light guide device array 101, wherein the focus of each of the microlenses is located on the front surface of the light guide device array.

[0051] In one embodiment, the laser module includes: a fiber laser and a collimating lens; the light beam emitted by the fiber laser is collimated by the collimating lens and then incident on the scanning galvanometer.

[0052] In another embodiment, the laser module includes: a fixed laser and a collimating lens; the light beam emitted by the fixed laser is collimated by the collimating lens and then incident on the scanning galvanometer.

[0053] The treatment head and hair growth treatment device proposed in this embodiment have the following advantages:

[0054] 1. The treatment head proposed in this embodiment combines the advantages of existing treatment heads. It is used in conjunction with a fractional laser and incorporates a light guide array. This is a contact-based treatment method that does not require numerous light sources, requiring only a single laser module. Via galvanometer scanning, the laser beam emitted by the laser module is controlled to land within each light guide in the light guide array. Furthermore, the separation of the treatment head from the laser module, which serves as the light source, facilitates cleaning and replacement of the treatment head, allowing it to be used by different users, thus avoiding the risk of cross-infection between patients.

[0055] 2. In the light guide array of the treatment head proposed in this embodiment, each light guide is equipped with a microlens to reduce the error in the laser beam landing point. Because each light guide is very small, the requirements for the laser beam landing point are high. A structure combining a microlens and a light guide is adopted. The microlens can perform secondary focusing on the laser beam. This structure can achieve a higher point density (more light guides) and a greater depth (the light guide height can be high). In use, it can ensure that existing hair and newly grown hair are effectively avoided during treatment, and the light guide can be accurately brought into contact with the scalp position that needs treatment.

[0056] 3. The treatment head of the hair growth therapy device adopts an integrated optical material structure. Combined with the pressing force and lasers of different wavelengths, it increases the penetration depth range of the scalp and the range of the effective light spot size during treatment, thereby improving the use effect of the hair growth therapy device.

[0057] In summary, this embodiment proposes a treatment head and a hair growth treatment device. In the treatment head, the treatment head body is detachably connected to the laser handpiece bracket. Compared with the situation in the related art where the treatment head of the treatment device cannot be replaced, after use, the treatment head body can be removed from the laser handpiece bracket so that the treatment head body can be cleaned and replaced, so that the treatment head can use the cleaned and replaced treatment head body to treat the next user, thereby improving the user experience; moreover, a light guide device array is provided on the treatment head body, and the user's scalp is treated by contacting multiple light guide devices in the light guide device array with the user's scalp, ensuring that the light spot formed on the front surface of the light guide device array can fall on the scalp, avoiding the light spot acting on the user's hair and causing damage such as breakage of the user's hair; furthermore, before the light beam enters the light guide device, the light beam is first converged by a microlens corresponding to the light guide device, so that the light beam can enter the light guide device more accurately, thereby increasing the use effect of the treatment head.

[0058] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
