Description

Technical Field

[0001] The utility model relates to the technical field of laser beauty equipment, in particular to a distance gauge and a treatment hand tool for auxiliary diversion. Background Art

[0002] Laser beauty is to penetrate a laser beam of a specific wavelength into the epidermis or dermis, and be absorbed by the target color base according to the light selective absorption effect. For example, 1064nm laser can destroy pigment cells and pigment particles. The destroyed fragments are processed and absorbed by the macrophages in the body, which is safe and does not leave scars, and effectively achieves the purpose of whitening. In order to facilitate medical staff to control the size of the light spot and perform laser beauty treatment more accurately, for laser handpieces with non-parallel light output, since the laser has a certain divergence angle, the distance between the laser source and the skin determines the size of the light spot. Therefore, a distance gauge is generally set on the laser beauty treatment handpiece, and the distance gauge is used to limit the distance between the skin and the laser source to assist in laser beauty treatment. In the process of realizing the present invention, the applicant found that the existing laser beauty treatment handpieces generally air-cool the skin treatment area during laser treatment to ensure skin safety and improve the laser treatment effect. At the same time, the dandruff and the like splashed by laser treatment can also be blown away in time to reduce the risk of lens contamination in the handpiece. However, the air cooling is generally sprayed from the handle, and the cooling air will drive dust and bacteria in the environment to the skin treatment area when passing through the distance gauge, resulting in an increased risk of skin infection.

[0033] In order to facilitate medical staff to control the size of the light spot and perform laser beauty treatment more accurately, for laser handpieces with non-parallel light output, since the laser has a certain divergence angle, the distance between the laser source and the skin determines the size of the light spot. Therefore, a distance gauge is generally set on the laser beauty treatment handpiece to limit the distance between the skin and the laser source. At the same time, the skin treatment area is air-cooled to keep the skin at a lower temperature to ensure skin safety and improve the laser treatment effect. At the same time, the dandruff and the like splashed by the laser treatment can also be blown away in time to reduce the risk of contamination of the lens in the handpiece. However, air cooling is generally sprayed from the handle of the laser beauty treatment handpiece, and when the cooling air passes through the distance gauge, it will drive dust and bacteria in the environment to the skin treatment area, resulting in an increased risk of skin infection. In order to solve the problem of high risk of skin infection during the cooling process, the present application provides a distance gauge and treatment handpiece with auxiliary diversion that reduces the risk of skin infection by shortening the air treatment path. The specific structure is shown in the following embodiment.

[0034] Example 1

[0035] The embodiment of the present application provides a distance gauge for assisting flow diversion, such as Figures 1 to 4 As shown, it includes a base 20 with a preset length along the axial direction, the base 20 includes a connecting portion 100 and a contact portion 200 provided at the distal end of the connecting portion 100, the distal end surface of the contact portion 200 is used to abut against the skin, and the distance between the skin and the laser emitting unit on the treatment handpiece is limited by the base 20 with a preset length along the axial direction. When the distal end surface of the contact portion 200 abuts against the skin, the laser emitting unit and the skin are in an effective treatment distance; a fluid outlet 210 is provided on the contact portion 200, and the outlet direction of the fluid outlet 210 is toward the contact portion 20 0, a fluid channel is provided on the connecting portion 100, the distal end of the fluid channel is connected to the fluid outlet 210, and the proximal end of the fluid channel is used to connect to a fluid source, which is used to generate a high-pressure fluid. When used in a laser cosmetic treatment handpiece, the fluid source is used to generate a cooling fluid, which can be a cooling liquid, a cooling gas, a mixture of liquid and gas, or a mixture of solid particles and gas, preferably cooling air, or cooling air containing an auxiliary laser treatment agent. The auxiliary laser treatment agent can improve the laser treatment effect or ensure skin safety. Figure 7As shown, the proximal end of the connecting portion 100 is used to connect to the handle 10 of the laser cosmetic treatment handpiece. When in use, the proximal end of the connecting portion 100 is connected to the distal end of the handle 10 of the laser cosmetic treatment handpiece, so that the axis of the distance gauge is parallel to the output light of the laser output unit on the treatment handpiece. Preferably, the axis of the distance gauge coincides with the output light of the laser output unit. The contact portion 200 is arranged around the axis of the distance gauge. The output light of the laser output unit passes through the distance gauge and irradiates the skin. The skin absorbs energy and heats up. At the same time, the fluid source generates cooling air that flows from the fluid channel to the fluid outlet 210, and then flows from the fluid outlet 210 to the skin corresponding to the output light to cool the skin. During the entire cooling air flow process, due to the guidance of the cooling air by the fluid channel, the flow path length of the cooling air in the air when it reaches the skin surface is reduced, thereby reducing the amount of air flowing to the skin surface with the cooling air, reducing the risk of the skin being infected by dust and bacteria in the ambient air, and improving the safety and treatment effect of laser cosmetic treatment.

[0036] To improve the cooling effect on the skin surface, e.g. Figures 3 to 5 As shown, the fluid channel can include an introduction section 110, a compression section 120, and a connecting section 130, arranged sequentially along the fluid flow direction. The connecting section 130 has a smaller diameter than the introduction section 110, while the compression section 120 gradually decreases in diameter along the fluid flow direction. The inner walls of the compression section 120, introduction section 110, and connecting section 130 form a smooth transition. Based on Bernoulli's principle, the cooling fluid is compressed when passing through the compression section 120, increasing its flow rate. This increases the flow rate of the cooling fluid sprayed from the fluid outlet 210 toward the skin surface. The greater the flow rate of the cooling fluid, the greater the cooling effect on the skin surface.

[0037] In order to facilitate medical staff to identify or predict the position where the laser is emitted to the skin surface, the contact part 200 can be set to a ring structure, and the center of the contact part 200 is located on the axis of the contact part 200, that is, the laser emission direction passes through the center of the contact part 200. Medical staff can identify or judge whether it corresponds to the target treatment point by the center of the contact part 200. Accordingly, the fluid outlet 210 is set on the inner side wall of the contact part 200, and the emission direction of the fluid outlet 210 corresponds to the center of the contact part 200, so that the cooling fluid is directly sprayed to the target treatment point on the skin, so that the cooling target of the cooling fluid is matched with the laser treatment target, and the two work together.

[0038] In some embodiments, the contact portion 200 may also be configured to include one or more arc-shaped structures, the arc center of the arc structure corresponding to the exit path of the laser light, and preferably the fluid outlet 210 is located inside the arc structure.

[0039] Since the fluid outlet 210 is located on the inner side of the contact portion 200, corresponding to the radial direction of the base 20, and the fluid channel is arranged along the axial direction of the base 20, in order to facilitate the smooth introduction of the cooling fluid into the fluid outlet 210, a fluid channel can be provided including a curved section 140 located at the contact portion 200, and the connecting section 130 is connected to the fluid outlet 210 through the curved section 140. The curved section 140 is used to guide the cooling fluid flowing along the axial direction of the base 20 to the circumferential direction of the base 20, thereby reducing the impact on the flow rate of the cooling fluid, thereby improving the cooling effect.

[0040] In some embodiments, in order to reduce the influence of the curved section 140 on the flow rate of the cooling fluid, a smooth transition between the inner wall of the curved section 140 and the inner wall of the adjacent connecting section 130 may be provided.

[0041] In some embodiments, in order to reduce the influence of the curved section 140 on the flow rate of the cooling fluid, the inner part of the inner wall of the curved section 140 smoothly transitions to the inner wall of the adjacent connecting section 130, and the outer part of the inner wall of the curved section 140 is provided with a transition plane 141. The angle between the transition plane 141 and the exit direction of the fluid outlet 210 is 45°, and the exit direction of the fluid outlet 210 is perpendicular to the exit direction of the connecting section 130, so that the cooling fluid flowing out of the connecting section 130 flows directly to the transition plane 141, is guided by the transition plane 141, and then flows directly to the fluid outlet 210, thereby reducing the contact time and collision contact area between the cooling fluid and the inner wall of the curved section 140, reducing the influence of the curved section 140 on the flow rate of the cooling fluid, and thereby improving the cooling effect.

[0042] During laser beauty treatment, the laser light acts on the corresponding treatment point of the skin, and the treatment point and the surrounding adjacent skin will absorb the laser energy, resulting in a trend of temperature increase at the treatment point and the surrounding adjacent skin. In order to ensure the safety of the treatment point and the surrounding adjacent skin, the connecting portion 100 can be provided to include a connecting column, and the fluid channel is provided on the connecting column. The projection of the connecting column and the fluid outlet 210 on the contact portion 200 along the axial direction of the base 20 is at most partially overlapped with the projection of the fluid outlet 210. When the cooling fluid flows from the connecting column to the contact portion 200, due to the fluid outlet 210 and the connecting column being on the axial direction of the base 20, the fluid outlet 210 and the connecting column are at most partially overlapped. There is a certain misalignment in the axial projection, and accordingly, there is a certain misalignment between the fluid channel and the fluid outlet 210 in the axial projection of the base 20. When the cooling fluid flows out of the fluid channel, it is affected by the non-misaligned part of the contact portion 200, which blocks the cooling fluid. In the process of the cooling fluid flowing out of the fluid outlet 210, the cooling fluid has a tendency to flow from the side of the fluid outlet 210 close to the connecting column to the side of the fluid outlet 210 away from the connecting column, so that the cooling fluid outflow amount of the fluid outlet 210 in the length direction is similar, so as to achieve uniform fluid discharge from the fluid outlet 210, and allow the cooling fluid to be evenly sprayed to the treatment point and the surrounding adjacent areas.

[0043] In some embodiments, in order to ensure the structural stability of the distance gauge, the connecting portion 100 can be provided with N connecting columns, N ≥ 2, and the contact portion is connected to the handle 10 of the therapeutic handpiece by the N connecting columns, so that the abutting pressure with the skin is distributed through the N connecting columns to avoid stress concentration, thereby improving the structural safety and stability of the connecting columns and the distance gauge; at least two of the N connecting columns are respectively provided with fluid channels, and the contact portion 200 is provided with multiple fluid outlets 210, and the fluid channels are connected to at least one fluid outlet 210. The multiple fluid outlets 210 form cooling fluids emitted in multiple directions, which can assist in cleaning impurities on the skin surface on the basis of effectively cooling the skin.

[0044] In order to improve the cooling effect on the skin, the connecting part 100 can be provided with a first connecting column and a second connecting column, and the first connecting column and the second connecting column are respectively provided with fluid channels. The contact part 200 is provided with a first fluid outlet 210a arranged near the first connecting column and a second fluid outlet 210b arranged near the second connecting column. The first fluid outlet 210a is connected to the fluid channel in the first connecting column, and the second fluid outlet 210b is connected to the fluid channel in the second connecting column. The fluid outlet direction of the first fluid outlet 210a and the fluid outlet direction of the second fluid outlet 210b are respectively located on different planes and are staggered, so that the cooling fluid of the first fluid outlet 210a and the cooling fluid of the second fluid outlet 210b are staggered with each other, and the relative flow rate between the two cooling fluids is doubled, so that the skin heat in this area can be more easily exchanged and carried away by the cooling fluid, thereby improving the cooling effect.

[0045] In order to precisely control the cooling effect on the skin, the axis corresponding to the fluid outlet direction of the first fluid outlet 210a and the axis corresponding to the fluid outlet direction of the second fluid outlet 210b can be set to be parallel, and one of the first fluid outlet 210a and the second fluid outlet 210b passes through the laser emission path. The laser is generated by the treatment handpiece. The cooling fluid generated by the first fluid outlet 210a passes through the skin treatment point along the first direction, while the cooling fluid generated by the second fluid outlet 210b flows in the opposite direction of the first direction and is offset and flows in parallel compared to the first fluid. That is, in the skin area adjacent to the skin treatment point, the two cooling fluids flow relative to each other, as shown in FIG. Figure 6 As shown, a cooling area with a relatively higher flow rate is formed near the treatment point, so that the heat of the treatment point and the adjacent skin can be more easily exchanged and carried away by the cooling fluid, thereby achieving precise cooling of the treatment point and the adjacent skin.

The proximal end of the connecting portion 100 is connected to the distal end of the handle 10. The distal end of the handle 10 is provided with a laser emitting unit. The light emitting direction of the laser emitting unit is parallel to the axial direction of the distance gauge. Preferably, the light emitting direction of the laser emitting unit coincides with the axial direction of the distance gauge. The therapeutic handpiece is used for laser beauty treatment. Preferably, the therapeutic handpiece is a handpiece of a laser therapy device. The therapeutic handpiece is provided with a laser output module. The laser output module generates laser light, which is emitted by the laser emitting unit to the treatment area. The operator holds the therapeutic handpiece and aims it at the patient's skin disease area. By controlling the therapeutic handpiece, the laser light is generated and irradiated on the patient's skin disease area. The laser beam penetrates the epidermis and dermis, destroying pigment cells and pigment particles. The fragments are processed and absorbed by the macrophages in the body, achieving beauty treatment.
