Therefore, compared with the prior art, the treatment device based on the irradiation light can avoid the surface skin burn of the target part.

An operator can control the on or off of the cooling device according to application requirements, such as requirements of a treated object, for example, when the irradiation time of the target part of the treated object is longer, the surface temperature of the target part is higher, and at this time, the cooling device of the treatment end 100 can be controlled to be turned on. In some embodiments, the present radiation-based treatment device further comprises: the temperature sensing device 104 is arranged at one end of the treatment end 100 close to the light output port; and the control device 210 is respectively connected with the temperature sensing device 104 and the refrigerating device, and is used for sending a first instruction according to the temperature signal output by the temperature sensing device 104, so that the refrigerating device performs refrigeration according to the first instruction.

For example, the control device 210 is configured to, if the temperature indicated by the temperature signal is greater than or equal to a first preset value, instruct to turn on the refrigeration device, so that the refrigeration device performs refrigeration. In this embodiment, the first preset value is not limited, and may be set according to application requirements in practical applications.

In some embodiments, the present radiation-based treatment device further comprises: the temperature sensing device 104 is arranged at one end of the treatment end 100 close to the light output port; and the control device 210 is respectively connected with the temperature sensing device 104 and the light emitting device, and is configured to send a second instruction according to the temperature signal output by the temperature sensing device 104, so that the light emitting device adjusts the emitted light according to the second instruction. The temperature obtained by the temperature sensing device 104 can reflect the temperature of the surface of the target part, and the treatment equipment realizes the intellectualization by monitoring the temperature of the surface of the target part and controlling the light emitting device according to the temperature of the surface of the target part.

In some embodiments, the control device 210 is configured to instruct to reduce the power of the light emitted by the light emitting device if the temperature indicated by the temperature signal is greater than or equal to a second preset value. In this embodiment, the value of the second preset value is not limited, and may be set according to the application requirement in practical application. For example, the second preset value is 42 ℃, and if the temperature of the surface of the target part is monitored to exceed 42 ℃, the light emitting device is controlled to reduce the power of the emitted light.

In some embodiments, the control device 210 is configured to instruct to control the light emitting device to stop emitting light if the temperature signal reflects that the rising rate of the temperature is greater than or equal to a third preset value. In this embodiment, the value of the third preset value is not limited, and may be set according to the application requirement in practical application. In this way, if the rate of temperature rise on the surface of the target portion is high, the light emitting device is turned off, and the treatment end 100 stops irradiating light. Illustratively, the third preset value is 1/5 ℃/s, i.e., 1 ℃ rise in 5 seconds, and the laser output is turned off when such a rapid rise in temperature occurs.

In this embodiment, the structure of the light emitting device is not limited, and the light emitting device includes, but is not limited to, a laser. In some embodiments, the therapeutic apparatus based on irradiation light further includes a water cooler and a cooling fan, wherein the water cooler and the cooling fan are respectively disposed at one side of the light emitting device, and the light emitting device is cooled by the water cooler and the cooling fan. In some embodiments, the therapeutic apparatus further includes a host, and the light emitting device and the control device 210 may be disposed in the host. Referring to fig. 2 and 3, fig. 2 is an overall schematic diagram of an irradiation light based treatment apparatus according to an embodiment, and fig. 3 is a top view of the irradiation light based treatment apparatus shown in fig. 2 after the upper cover is opened. As shown, the host computer is provided with a laser 205 and a control device 210, the laser 205 is connected with the treatment end 100 through the light guide 110, a connecting piece 111 is arranged at one end of the light guide 110 connected with the laser 205, and the light guide 110 is connected with an interface of the laser 205 through the connecting piece 111. If the light guide 110 is an optical fiber, the connection element 111 may be an optical fiber connector. The treatment end 100 may be configured to be removable, and the treatment end 100 may be configured to be removable from the host, such as by configuring different treatment ends 100 for different conditions.

A water cooler 206 and a heat radiation fan 207 are provided on the laser 205 side. The host is also provided with a power supply 209 and a power supply air switch 208. The host is also provided with a screen 201, a scram switch 202 and a power switch 203. A stand 204 is provided on the host side, the stand 204 being used for placing the treatment end 100.

The wave band which can penetrate through the tissue well to a deeper depth can be selected as a preset wave band, so that the light energy penetrates through the surface layer of the target part to a deeper depth. Has the effect of deep treatment. In some embodiments, the predetermined wavelength band includes 1270nm, and reference is made to fig. 4, where fig. 4 is a graph of absorption curves of water, hemoglobin, oxygenated hemoglobin, and melanin, where as the wavelength increases, melanin absorption is continuously decreasing, but water absorption is continuously increasing, so that there is a wavelength where melanin and water absorption are relatively low, where light is less absorbed, and can penetrate deeper. In the figure, the arrow indicates a position where melanin and water absorption are relatively low, and the arrow indicates a wavelength of about 1270nm. Thus, as can be seen from fig. 4, 1270nm light can penetrate better the skin tissue composed of water (water), hemoglobin (Hemoglobin), oxyhemoglobin (Oxyhemoglobin), and the deeper the penetration into the target site, the better the therapeutic effect. For example, a preset wavelength band with a central wavelength of 1270nm, for example, the light emitting device emits light with a wavelength band of 1270±20nm, and a semiconductor laser with an emitting light with a wavelength band of 1270±20nm may be used.

The using method of the treatment device of the embodiment is as follows:

After the treatment device is powered on, the power switch 203 is pressed down to enter a preparation state, and the program can select continuous laser and quasi-continuous laser to treat. And different laser intensities and treatment times can be selected according to different treatment positions.

Before treatment, the optical fiber connector of the treatment end 100 is required to be inserted into the host, the light-transmitting sheet 101 of the optical output port of the treatment end 100 is attached to the part to be treated, and after the laser switch is triggered, the laser 205 in the host emits laser to be transmitted to the optical output port of the treatment end 100 through the optical fiber, so that the laser enters the tissue of the treated object.

In treatment, the temperature of the treatment end 100 is typically set at 42 ℃, and at most 45 ℃, and when the temperature of the surface of the tissue to be treated (skin) is too high, the refrigerating device starts to operate, and heat generated by the laser is taken away and dissipated through the heat sink 103. Because the light output port adopts the heat conducting glass, the heat generated by skin tissues can be well conducted to the refrigerating sheet 102.
