Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a therapeutic hand and a therapeutic instrument. Background Technology

[0002] Currently, medical devices such as intense pulsed light (IPL) therapy devices and laser therapy devices are widely used in the medical industry. IPL devices typically use xenon lamps as the light source, which can generate a spectrum with wavelengths from 400nm to 1200nm to meet different treatment needs. A cooling structure is located on the side of the light window in the device. This cooling structure lowers the temperature of the light window during treatment to alleviate pain for the user. The cooling structure generally requires power, so it is usually located close to the light source for easy wiring between the light source and the cooling structure. However, this placement results in the cooling structure being located far from the contact point between the light window and the treatment surface, reducing the cooling rate of the treatment surface and affecting pain relief for the user. Summary of the Invention

[0003] The main objective of this invention is to provide a treatment hand and device that aims to improve the cooling speed of the treatment surface and quickly relieve the patient's pain during treatment.

[0006] A light-transmitting component, comprising a light-incident end and a light-exit end, the light-incident end being connected to the light-emitting component, and the light-exit end comprising an abutment surface and a first peripheral side surface connected at an angle to the abutment surface, the abutment surface being used to abut against the treatment surface; and

The cooling component and the structural component are connected, and the structural component is detachably connected to the light-emitting component.

[0012] In one embodiment, the light-transmitting component further includes a filter, which is attached to the side of the second light-transmitting element that is close to the first light-transmitting element.

[0013] In one embodiment, the treatment handpiece further includes a storage chip disposed on the second light-transmitting element, the storage chip being used to record the filtering information of the filter and / or the light transmission information of the second light-transmitting element.

[0019] The present invention also proposes a therapeutic device, the therapeutic device comprising:

[0020] Treatment host; and

[0021] The treatment handpiece described above is connected to the treatment host.

[0032] Please refer to the reference. Figure 1 and Figure 2 As shown, the present invention proposes a therapeutic handpiece 100, which includes a light-emitting component 1, a light-transmitting component 2, and a cooling component 3. The light-emitting component 1 is used to provide a therapeutic light source; the light-transmitting component 2 is provided with an incident light end 211 and an exit light end 222. The incident light end 211 is connected to the light-emitting component 1, and the exit light end 222 is provided with an abutting surface 2221 and a first peripheral side surface 2222 connected at an angle to the abutting surface 2221. The abutting surface 2221 is used to abut against the therapeutic surface; the cooling component 3 includes a cooling surface 311, which is attached to the first peripheral side surface 2222.

[0033] In this embodiment, the light-emitting end 222 includes an abutment surface 2221 and a first peripheral side surface 2222. When the treatment handpiece 100 performs treatment, the abutment surface 2221 abuts against the treatment surface. The treatment light emitted by the light-emitting component 1 enters through the light-incident end 211 of the light-transmitting component 2, passes through the light-emitting end 222 of the light-transmitting component 2, and exits from the abutment surface 2221, ultimately reaching the patient's skin for treatment. The treatment surface is the skin surface of the patient to be treated that is irradiated by the treatment light source. The cooling surface 311 of the cooling component 3 is attached to the first peripheral side surface 2222. When the treatment handpiece 100 performs treatment, it cools the light-transmitting component 2 to reduce the temperature of the abutment surface 2221, thereby cooling the patient's treatment surface and preventing burns from excessively high treatment temperatures. It also alleviates the patient's pain during treatment. The cooling surface 311 is attached to the first peripheral side 2222 near the contact surface 2221, which is closer to the contact surface 2221. This can improve the efficiency of heat transfer with the contact surface 2221, further improve the cooling effect on the contact surface 2221, and enhance the effect of relieving the patient's pain.

[0034] In some embodiments, the cross-sectional area of ​​the light-emitting end 222 gradually decreases from the end furthest from the abutment surface 2221 to the end closest to the abutment surface 2221. This is because when a doctor holds the treatment handpiece 100 for treatment, the abutment surface 2221 needs to be placed against the skin. During this process, the abutment position needs to be observed. Setting the area of ​​the side of the light-emitting end 222 closest to the abutment surface 2221 to be smaller makes it easier for the doctor to observe the position of the skin against which the abutment surface 2221 is placed, so that the light from the treatment light source can be accurately applied to the skin to be treated. In actual implementation, the light-emitting end 222 can be shaped like a frustum or a pyramid. The abutment surface 2221 can be an arc surface with a large radius of curvature or a plane, which is not specifically limited here. The connection between the abutment surface 2221 and the first peripheral side 2222 is chamfered to reduce the patient's discomfort when the light-emitting end 222 scrapes against the treatment surface. The shape of the light-emitting end 222 can be a trapezoidal or frustum shape, or a three-dimensional structure shape that gradually decreases in size from the end away from the contact surface to the end closer to the contact surface. That is, one of the cross-sections along the optical axis can be a trapezoid.

[0035] The contact surface 2221 can be coated with an anti-reflective film to improve light transmittance. When the treatment handpiece 100 performs treatment using a suspended, rapid sweeping method without direct skin contact, a strong, wear-resistant, hardened hydrophilic film can be added on top of the anti-reflective film. Under the cooling effect of the cooling component 3, the surface of the hardened hydrophilic film will quickly condense to form a thin and uniform water film, instead of forming a hazy droplet layer, further improving light transmittance. Alternatively, a hardened hydrophobic film can be added to the contact surface 2221 on top of the anti-reflective film. This prevents the contact surface 2221 from adsorbing small droplets during treatment, keeping the contact surface 2221 dry and clean, and improving light transmittance.

[0036] In one embodiment of the present invention, such as Figure 1 and Figure 2 As shown, the light-transmitting component 2 includes a first light-transmitting element 21 and a second light-transmitting element 22 arranged at intervals along the light-emitting direction. The first light-transmitting element 21 has a light-incident end 211, and the second light-transmitting element 22 has a light-emitting end 222.

[0037] In this embodiment, the light-incident end 211 and the light-exit end 222 are respectively disposed on the first light-transmitting element 21 and the second light-transmitting element 22. The therapeutic light emitted by the light-emitting component 1 first enters the first light-transmitting element 21, then is conducted from the first light-transmitting element 21 to the second light-transmitting element 22, and finally exits from the contact surface 2221 of the second light-transmitting element 22. The cooling surface 311 of the cooling component 3 is attached to the second light-transmitting element 22, and the second light-transmitting element 22 and the first light-transmitting element 21 are spaced apart. This can greatly reduce the heat transfer efficiency between the second light-transmitting element 22 and the first light-transmitting element 21, and prevent the second light-transmitting element 22 from transferring cold energy to the first light-transmitting element 21 and heat energy from the first light-transmitting element 21 to the second light-transmitting element 22 when the cooling component 3 is cooling the second light-transmitting element 22, thus avoiding affecting the cooling efficiency of the cooling component 3 on the second light-transmitting element 22.

[0038] In actual implementation, the first light-transmitting element 21 and the second light-transmitting element 22 are coaxially arranged to ensure the transmittance of light through them. Both the first light-transmitting element 21 and the second light-transmitting element 22 are made of sapphire. Sapphire not only has high thermal conductivity and light conductivity, but also good wear resistance and thermal stability, effectively ensuring the service life of the light-transmitting component 2. Relatively speaking, the volume of the first light-transmitting element 21 is larger than that of the second light-transmitting element 22, meaning that the second light-transmitting element 22 occupies a smaller volume proportion in the light-transmitting component 2. This makes the second light-transmitting element 22 easier to be completely cooled by the cooling component, resulting in better cooling of the contact surface 2221.

[0039] In one embodiment of the present invention, such as Figure 1 and Figure 2 As shown, a heat insulation cavity 23 is formed between the first light-transmitting element 21 and the second light-transmitting element 22. The light-transmitting assembly 2 also includes a heat insulation sealing element 24, which is arranged around the heat insulation cavity 23. The heat insulation sealing element 24 is used to reduce the heat conduction between the first light-transmitting element 21 and the second light-transmitting element 22.

[0040] In this embodiment, the first light-transmitting element 21 and the second light-transmitting element 22 are spaced apart to form a heat insulation cavity 23. A heat insulation sealing element 24 is disposed between the first light-transmitting element 21 and the second light-transmitting element 22 to seal the heat insulation cavity 23 formed between the first light-transmitting element 21 and the second light-transmitting element 22, preventing moisture or other impurities from entering the heat insulation cavity 23 and affecting the light transmission between the first light-transmitting element 21 and the second light-transmitting element 22. At the same time, the heat insulation sealing element 24 ensures that the first light-transmitting element 21 and the second light-transmitting element 22 are maintained at a preset distance, preventing relative movement due to shaking or vibration. The first light-transmitting element 21 and the second light-transmitting element 22 remain in a close but not overlapping state, preventing the cold air of the second light-transmitting element 22 from being transferred to the first light-transmitting element 21, and enhancing the cooling effect of the cooling component 3 on the second light-transmitting element 22.

[0041] Understandably, the heat insulation seal 24 is arranged around the heat insulation cavity 23 to prevent the heat insulation seal 24 from blocking the transmission path of the therapeutic light and affecting the transmission efficiency of the therapeutic light. The heat insulation seal 24 can be made of materials with good high temperature resistance, heat insulation and sealing properties, such as rubber or ceramic fiber.

[0042] In actual implementation, the heat insulation cavity 23 can be filled with dry gas or set in a vacuum to further reduce the heat transfer efficiency between the first light-transmitting element 21 and the second light-transmitting element 22.

[0043] In one embodiment of the present invention, such as Figure 1 and Figure 2 As shown, the second light-transmitting element 22 is connected to the cooling component 3. The treatment handpiece 100 also includes a structural component. The cooling component 3 is connected to the structural component, and the structural component is detachably connected to the light-emitting component 1.

[0044] In this embodiment, the second light-transmitting element 22, the cooling component 3, and the structural component are modularly arranged. The structural component is detachably connected to the light-emitting component 1, so that the second light-transmitting element 22 connected to the light-emitting component 1 can be replaced.

[0045] Understandably, by replacing the second light-transmitting element 22 with different sizes, shapes and tapers, the contact surface 2221 of the second light-transmitting element 22 can be changed, thereby changing the spot size of the therapeutic light emitted from the second light-transmitting element 22. This can meet the needs of different patients and different treatment sites for the size of the therapeutic spot.

[0046] The size of the therapeutic light spot emitted from the contact surface 2221 is consistent with the size of the contact surface 2221. Within a certain taper range, by finely adjusting the taper and length of the second light-transmitting component 22, the size of the contact surface 2221 of the second light-transmitting component 22 can be changed, thereby changing the size of the therapeutic light spot emitted from the contact surface 2221. Compared to using a metal part with a light guide rod to cover the contact surface 2221 of the light-transmitting component 2 to reduce the size of the therapeutic light spot, adjusting the therapeutic light spot by replacing the second light-transmitting component 22 can avoid heat accumulation and overheating on the metal part, which could lead to burns to the patient and affect the service life of the treatment handpiece 100.

[0047] In practical implementation, the first light-transmitting element 21 is connected to the light-emitting component 1. The first light-transmitting element 21 is not replaced when the second light-transmitting element 22 is replaced, thus saving on the usage cost of the treatment handpiece 100. The second light-transmitting element 22 is bonded to the cooling surface 311 of the cooling component. When replacing the second light-transmitting element 22, the cooling component and the second light-transmitting element 22 can be replaced together, ensuring that the cooling component and the second light-transmitting element 22 are compatible in size and cooling effect. A filter 25 can be disposed on the second light-transmitting element 22, so that the filter 25 can also be replaced at the same time as the second light-transmitting element 22, thereby changing the wavelength of the therapeutic light emitted from the contact surface 2221 to meet different treatment needs.

[0048] Understandably, the light-emitting component 1 includes an electrical connection module that is electrically connected to the treatment host. The light-emitting component 1 is electrically connected to the power supply unit and control unit of the treatment host through the electrical connection module. Specifically, the electrical connection module can be a control circuit board.

[0049] In practical implementation, the light-emitting component 1 may also include a housing structure mechanically connected to the structural component, and the electrical connection module of the light-emitting component 1 is correspondingly provided with a pin terminal; the structural component can be detachably connected to the housing structure of the light-emitting component 1 through a snap-fit ​​structure or a plug-in structure, and the structural component is also provided with a pin terminal coupled to the pin terminal, which can be electrically connected to the cooling component and the memory chip 4. The structural component can be mechanically connected to the housing structure through a plug-in structure or a snap-fit ​​structure, and the pin terminal is also coupled to the pin terminal to achieve electrical connection, thus realizing the detachable setting of the cooling component 3 in terms of both mechanical structure and electrical connection. The cooling component 3 and the storage chip 4 are electrically connected to the power supply unit and control unit of the treatment host through an electrical connection module. This allows the treatment host to control the working state of the cooling component 3 and communicate with the storage chip 4. The treatment host can read the light transmission information of the second light-transmitting element 22 and the filter information of the filter 25 stored on the storage chip 4, and control the light-emitting component 1 to work at an appropriate power through software processing, so that the therapeutic light emitted from the second light-transmitting element 22 has the energy density required for treatment. In this way, the utilization rate of light energy is extremely high, and no excessive waste light and heat will be generated to burn the patient.

[0050] In one embodiment of the present invention, such as Figure 1 and Figure 2 As shown, the light-transmitting component 2 also includes a filter 25, which is attached to the side of the second light-transmitting component 22 near the first light-transmitting component 21. The filter 25 is used to allow therapeutic light of a specific wavelength to pass through.

[0051] In this embodiment, the filter 25 allows therapeutic light within a specific wavelength range to pass through while blocking other wavelengths, thereby improving the therapeutic effect of the therapeutic light emitted from the contact surface 2221 on the patient. The filter 25 is attached to the second light-transmitting element 22, rather than the first light-transmitting element 21. This allows the cooling assembly 3 to also cool the filter 25, preventing the surface of the filter 25 from heating up due to light filtering, thus avoiding accelerated damage and aging and extending its lifespan. Simultaneously, the filter 25 is attached to the side of the second light-transmitting element 22 closest to the first light-transmitting element 21, i.e., the side facing away from the contact surface 2221. This prevents the filter 25 from being directly exposed to the external environment, thereby extending its lifespan.

[0052] In practical implementation, by setting different types of filters 25, therapeutic light of different wavelength ranges can be transmitted, thereby causing the contact surface 2221 of the light-transmitting component 2 to emit therapeutic light of different wavelengths, thus specifically meeting the treatment needs of different patients, different parts of the body, or different types of diseases, and improving the therapeutic effect of the treatment handpiece 100. Furthermore, it should be noted that since the first light-transmitting component 21 and the light-emitting component 1 are fixedly connected, the second light-transmitting component 22 and the cooling component 3 are fixedly connected, while the cooling assembly 3 and the light-emitting assembly 1 are detachably connected, it is equivalent to the first light-transmitting component 21 and the second light-transmitting component 22 being detachably connected. Simultaneously, the aforementioned filters 25 can also be formed by coating the second light-transmitting component 22 close to the first light-transmitting surface 21. In a treatment handpiece, there are multiple second light-transmitting components 22, each coated with a filter 25 of a different wavelength, so that when replacing a second light-transmitting component 22, the corresponding wavelength filter can be directly replaced.

[0053] In one embodiment of the present invention, such as Figure 1 and Figure 2 As shown, the light-emitting component 1 includes a xenon lamp 11 and a reflector 12. The reflector 12 is provided with a reflective groove 121. The xenon lamp 11 is disposed in the reflective groove 121. A first light-transmitting element 21 is connected to the reflector 12 and covers the opening of the reflective groove 121. A cooling medium is disposed in the reflective groove 121 for cooling the xenon lamp 11.

[0054] In this embodiment, the reflector 12 is used to reflect the light emitted by the xenon lamp 11 to the light-transmitting component 2, thereby improving the light utilization rate. As an incoherent light source, the light flux coupled to the light-transmitting component 2 by the xenon lamp 11 decreases with increasing distance. Therefore, the first light-transmitting component 21 directly covers the opening of the reflector groove 121. This not only eliminates the need for a sealing structure at the opening of the reflector groove 121, making the entire photonic handheld device structure more compact, but also brings the first light-transmitting component 21 closer to the xenon lamp 11, thereby increasing the light flux coupled into the first light-transmitting component 21 and improving the light energy utilization rate.

[0055] Understandably, the walls of the reflector groove 121 are curved to reflect the light emitted by the xenon lamp 11 towards the first light-transmitting element 21 that covers the opening of the reflector groove 121, thereby improving the light utilization rate. Optionally, the light-emitting element can be a reflector or a reflector bowl, etc.

[0056] In practical implementation, the first light-transmitting element 21 can be bonded to the reflector 12 by means of dispensing adhesive or sealing and pressing, so that the reflector groove 121 forms a sealed cavity. A cooling medium can flow inside the reflector groove to dissipate heat from the xenon lamp 11, keeping it at its normal operating temperature, ensuring the stability of the xenon lamp 11's operation, and extending its service life. The reflector 12 can also be provided with a protruding structure for limiting the first light-transmitting element 21. The protruding structure limits the connection between the reflector 12 and the first light-transmitting element 21 along its circumference, thereby improving the connection stability.

[0057] In one embodiment of the present invention, such as Figure 1 and Figure 2 As shown, the treatment handpiece 100 also includes a storage chip 4, which is disposed on the second light-transmitting element 22. The storage chip 4 is used to record the filtering information of the filter 25 and / or the light transmission information of the second light-transmitting element 22.

[0058] Understandably, the treatment handpiece 100 is usually also connected and communicates with the treatment host, through which the doctor can observe and control the operation of the light-emitting component 1 and the cooling component 3.

[0059] In this embodiment, the storage chip 4 can record the wavelength information of the light allowed to pass through the filter, and can also record the spot size of the therapeutic light emitted through the contact surface 2221. When the treatment handpiece 100 is connected and communicates with the treatment host, the treatment host can read the filter information recorded by the storage chip 4 so that the physician can determine the wavelength of the therapeutic light emitted from the contact surface 2221, and then perform targeted treatment on the patient.

[0060] The cross-sectional area of ​​the second light-transmitting element 22 gradually decreases from the end furthest from the abutment surface 2221 to the end closest to the abutment surface 2221. That is, the second light-transmitting element is conical or frustum-shaped with a certain taper. Depending on its height or taper, the light spot size of the treatment light source emanating from the abutment surface 2221 can be different, corresponding to different light transmission information. Simultaneously, the treatment host can read the light transmission information of the second light-transmitting element 22 through the storage chip 4, and then automatically control the luminous power of the light-emitting component 1 through a software algorithm. This ensures that the luminous power of the light-emitting component 1 matches the light spot size of the treatment light emitted from the abutment surface 2221, enabling the treatment light to achieve the required treatment energy density. The energy density of the treatment light is equal to the ratio of total energy to the light spot area.

[0061] Understandably, the area of ​​the therapeutic light spot emitted through the contact surface 2221 of the second light-transmitting element 22 is the area of ​​the contact surface 2221. The area of ​​the contact surface 2221 can be directly recorded in the storage chip 4. The treatment host can calculate the required energy of the therapeutic light by preset energy density of the therapeutic light, and then control the light emission power of the light-emitting component 1 accordingly, so as to avoid the light emission power of the light-emitting component 1 being too low or too high, affecting the treatment effect or causing waste of light energy.

[0062] In one embodiment of the present invention, such as Figure 1 and Figure 2 As shown, the cooling component 3 includes a cooling element 31 and a heat sink 32. The cooling element 31 has a heat dissipation surface and a cooling surface 311 opposite to the heat dissipation surface. The heat sink 32 is connected to the side of the cooling element 31 away from the cooling surface 311 and is connected to the light-emitting component 1.

[0063] In this embodiment, the heat sink 32 can dissipate heat from the cooling component 31 to ensure that the cooling surface 311 of the cooling component 31 is in a normal cooling state. Simultaneously, the heat sink 32 is connected to the light-emitting component 1, enhancing the stability of the cooling component 3 and improving the overall integrity of the treatment handpiece 100. Optionally, the heat sink 32 and the light-emitting component 1 can be detachably connected via a snap-fit ​​structure or a plug-in structure to facilitate maintenance and replacement of the cooling component 3 and the light-transmitting component 2.

[0064] Understandably, the cooling element 31 can be a semiconductor refrigerator, a device that utilizes the thermoelectric effect of semiconductors for cooling. It achieves cooling or heating by generating a Peltier effect through a direct current passing through a couple composed of two different metals or semiconductor materials. Semiconductor refrigerators have advantages such as small size, light weight, no moving parts, quiet operation, and no pollution, making them particularly suitable for fields requiring precise temperature control. Semiconductor refrigerators operate based on the Peltier effect; when a direct current passes through a couple composed of two different metals or semiconductor materials, one end of the couple absorbs heat, and the other end releases heat, thus achieving a cooling effect. Therefore, the side of the cooling element 31 facing away from the cooling surface 311 forms a heat dissipation surface. The cooling surface 311 of the cooling element 31 is closely attached to the second light-transmitting element 22 to ensure the cooling effect on the contact surface 2221. The heat dissipation surface of the cooling element 31 is closely connected to the heat dissipation element 32 to improve the heat transfer efficiency between the heat dissipation surface and the heat dissipation element 32, ensuring the heat dissipation efficiency of the heat dissipation element 32 on the heat dissipation surface. The heat sink 32 can be a water-cooled heat sink structure or an air-cooled heat sink fin structure; no specific limitation is made here.

[0065] In practical implementation, the cooling surface 311 of the cooling component 31 is connected to the first peripheral side 2222 via thermally conductive gel or grease, and the heat dissipation surface of the cooling component 31 is also connected to the heat dissipation component 32 via thermally conductive gel or grease to ensure heat transfer efficiency. The cooling assembly 3 may also include a temperature detector, which is disposed on the cooling surface 311, abutting against the first peripheral side 2222, and electrically connected to the cooling component 31. The temperature detector is used to detect the temperature of the second light-transmitting element 22. The temperature detection element may be an NTC (Negative Temperature Coefficient) temperature sensor, which is a temperature measuring element based on an NTC thermistor. The resistance of this thermistor decreases as the temperature increases. By utilizing the pre-measured mathematical relationship between resistance and temperature, the resistance value can be converted into a temperature value, thereby realizing temperature measurement.

[0066] In one embodiment of the present invention, such as Figure 1 and Figure 2 As shown, the heat sink 32 includes a first segment and a second segment connected at an angle. The first segment extends along the first peripheral side 2222, and the second segment extends to a position close to the light-incident end 211. In some embodiments, the light-incident end 211 is the aforementioned first light-transmitting element 21, and the second segment extends along the peripheral side of the first light-transmitting element 21.

[0067] In this embodiment, the heat sink 32 is arranged along the first peripheral side 2222 and the second light-transmitting element 22 to maximize the area of ​​the heat sink 32 and improve its heat dissipation effect. Optionally, the first segment of the heat sink 32 is arranged parallel to the first peripheral side 2222, and the second segment of the heat sink 32 is arranged parallel to the peripheral side of the first light-transmitting element 21. This can also prevent the heat sink 32 from obstructing the doctor's view.

[0068] In practical implementation, the second section of the heat sink 32 is close to but not in contact with the peripheral side of the first light-transmitting element 21, making the peripheral side of the first light-transmitting element 21 suspended. This creates a high refractive index difference between the first light-transmitting element 21 and the air, resulting in total internal reflection of light. This significantly reduces the light leakage rate during transmission through the first light-transmitting element 21, thereby improving light utilization. Optionally, the side of the second section of the heat sink 32 closest to the first light-transmitting element 21 is smooth. This allows light overflowing from the peripheral side of the first light-transmitting element 21 to be reflected back into the first light-transmitting element 21, avoiding light waste and improving the light-guiding efficiency of the first light-transmitting element 21. Furthermore, a reflective material can be coated on the side of the second section of the heat sink 32 closest to the first light-transmitting element 21 to form a reflective material layer, further improving the efficiency of reflecting back the light refracted by the first light-transmitting element 21 and further enhancing the light-guiding efficiency. The reflective material layer can also be formed by coating on the heat sink, or by fixing a structure with a reflective material layer to the heat sink 32 by bonding or other means.

[0069] Optionally, the cooling component 3 includes a cooling element 31 and a temperature sensor. The cooling element 31 and the temperature sensor are electrically connected to the treatment host through an electrical connection module. The temperature sensor can detect the temperature of the second light-transmitting element 22. The treatment host can control the current flowing into the cooling element 31 according to the detection data of the temperature sensor to control the cooling power of the cooling element 31, thereby controlling the temperature of the second light-transmitting element 22 within a preset range.

[0070] In one embodiment of the present invention, such as Figure 1 and Figure 2 As shown, the first light-transmitting element 21 has a light-emitting surface 212 on the side near the second light-transmitting element 22, and the second light-transmitting element 22 has a light-incident surface 221 on the side near the first light-transmitting element 21. The area of ​​the light-incident surface 221 is larger than the area of ​​the light-emitting surface 212.

[0071] In this embodiment, the therapeutic light emitted by the light-emitting component 1 is emitted from the light-emitting surface 212 of the first light-transmitting component 21 and then enters the second light-transmitting component 22 from the light-incident surface 221. This achieves the transmission of therapeutic light from the first light-transmitting component 21 to the second light-transmitting component 22. The area of ​​the light-incident surface 221 is larger than the area of ​​the light-emitting surface 212, so that the light emitted from the light-emitting surface 212 can penetrate the light-emitting surface 212 as much as possible, thereby improving the light coupling efficiency between the first light-transmitting component 21 and the second light-transmitting component 22, reducing light loss during transmission, and ensuring the therapeutic effect of the therapeutic handpiece 100.

[0072] In actual implementation, the light-emitting surface 212 and the light-incident surface 221 are coaxially arranged, and they can be circular to ensure the light coupling efficiency between the first light-transmitting element 21 and the second light-transmitting element 22. The diameter difference between the light-incident surface 221 and the light-emitting surface 212 is between 2mm and 5mm to avoid the light-incident surface 221 being too large or too small. If the light-incident surface 221 is too large, the overall structure of the treatment handpiece 100 may become too bulky, affecting the doctor's observation line of sight and operation; if the light-incident surface 221 is too small, it may affect the light coupling efficiency between the second light-transmitting element 22 and the first light-transmitting element 21.

[0073] In one embodiment of the present invention, the shape of the cooling surface 311 is the same as the shape of the first peripheral side surface 2222.

[0074] In this embodiment, the first peripheral side 2222 is defined as having three or more surfaces, one or more of which are fitted with the aforementioned cooling components, with the cooling surface of the cooling component attached to one of the surfaces. In some other embodiments, multiple cooling components are used, with each cooling surface 311 of the multiple cooling components attached to one of the surfaces of the first peripheral side 2222, allowing multiple cooling components 3 to conduct cold energy simultaneously through multiple surfaces of the first peripheral side 2222, thereby rapidly cooling the light-emitting end 222. The cooling surface 311 and the corresponding fitted surface of the first peripheral side 2222 have the same shape and are close to or the same size, so that the cooling surface 311 can surround the corresponding surface of the first peripheral side 2222, preventing cold energy from being conducted from the surface of the first peripheral side 2222 into the air, thus avoiding loss of cold energy. In some embodiments, the shapes and sizes of the two surfaces are exactly the same. Figure 1 and Figure 2 As shown, there are two cooling components 3, with their two cooling surfaces 311 attached to the two opposite surfaces of the first peripheral side 2222.

[0075] This invention also proposes a therapeutic device, such as... Figure 1 As shown, the therapeutic device includes a treatment host and a treatment handpiece 100. The specific structure of the treatment handpiece 100 is as described in the above embodiments. Since this therapeutic device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated here. The treatment handpiece 100 is connected to the treatment host. The physician can observe and control the working state of the treatment handpiece 100 through the treatment host. For example, the physician can adjust the light emission time and intensity of the light-emitting component 1 through the treatment host, thereby controlling the treatment time and intensity of the treatment handpiece 100; the physician can adjust the cooling intensity of the cooling component 3 through the treatment host to adjust the cooling intensity of the contact surface 2221 on the treatment surface for different patients, so that the patient can obtain the best treatment experience.
