[0025] The main objective of this invention is to provide a therapeutic handpiece 100 that improves the heat dissipation capability of the mechanism component 11.

[0026] To achieve the above objectives, please refer to Figure 1 The treatment handpiece 100 includes: Handle 10, handle 10 for receiving movement assembly 11, handle 10 having air inlet 10a; and Heat pipe 20 is connected to handle 10; heat pipe 20 has a flow channel located outside handle 10, the flow channel is connected to air inlet 10a to form a heat dissipation duct, the heat dissipation duct is configured to dissipate heat from the movement assembly 11.

[0027] The therapeutic handpiece 100 proposed in this utility model is used to electrically connect to the therapeutic host. The therapeutic host includes a power supply module, a control module, etc. The power supply module can provide stable and suitable electrical energy to the therapeutic handpiece 100. The control module has a built-in control chip and operating program. Medical staff can set treatment parameters, such as output power, treatment time, energy intensity, radio frequency / laser wavelength, etc., through the panel of the therapeutic host. The host then transmits the control signal to the therapeutic handpiece 100 to ensure that the treatment process is precise and controllable.

[0028] The handle 10 is used for being held, and its treatment end is used to align with the patient's lesion. The core component 11 is used to output electrical energy into therapeutic energy that can perform pathological treatment on the patient, such as light energy, radio frequency energy, ultrasound, etc. The core component 11 can be a radio frequency energy core component 11, which can convert electrical energy into high-frequency radio frequency energy, which acts on the lesion tissue through electrodes to achieve ablation, coagulation, tightening and other treatments. Alternatively, the core component 11 can also be a xenon lamp component, which converts electrical energy into intense pulsed light to achieve precise whitening, skin rejuvenation and other treatments. Here, the specific type of core component 11 is not limited. The air inlet 10a of the treatment handpiece 100 is connected to the receiving space of the handle 10. The receiving space of the handle 10 is used to receive the core component 11. In this way, when the handle 10 has the conditions for air flow to form an airflow, the heat generated by the core component 11 can be discharged from the handle 10 in time, thereby achieving cooling of the core component 11.

[0029] One end of the heat dissipation pipe 20 is inserted into the handle 10 to connect with it, so that the flow channel of the heat dissipation pipe 20 can connect to the air inlet 10a of the handle 10; in one embodiment, the heat dissipation pipe 20 is connected to the treatment host, which is equipped with a second cooling fan. The host housing of the treatment host also has an air outlet, so that the cooling duct of the treatment handpiece 100 can connect to the air outlet of the treatment host. Driven by the second cooling fan, air can enter the cooling duct from the air inlet 10a of the handle 10, and the hot air in the cooling duct can be discharged through the air outlet of the treatment host, thereby ensuring that the heat of the core component 11 can be carried out of the handle 10 immediately. Meanwhile, because... The heat dissipation pipe 20 has its flow channel located on the outside of the handle 10. After absorbing heat, the hot air is directly introduced into the main unit for exhaust, preventing it from circulating and accumulating inside the handle 10 and avoiding a continuous rise in temperature around the mechanism. At the same time, the second cooling fan is located in the treatment main unit rather than in the handle 10, which can reduce the weight of the handle 10. When the user holds the handle 10, the grip force can be reduced, and the user will not experience soreness or fatigue due to the excessive weight of the handle 10. Even during long-term operation, the user can maintain grip stability and treatment accuracy. Especially in scenarios that require fine adjustment of treatment angle and continuous aiming at the lesion, the weight reduction of the handle 10 can significantly reduce the operational burden of medical staff and improve the efficiency of diagnosis and treatment.

[0030] In this technical solution, the handle 10 of the treatment handpiece 100 is used to accommodate the core component 11. The handle 10 is connected by a heat dissipation pipe 20. The heat dissipation pipe 20 has an independent flow channel, which is connected to the air inlet 10a of the handle 10. In this way, airflow can enter from the air inlet 10a of the handle 10 to remove the heat generated by the core component 11. The heat can be discharged immediately through the flow channel. At the same time, the air entering from the air inlet 10a is always fresh air that has not undergone heat absorption, which can ensure the cooling effect on the core component 11.

[0031] Further, please refer to Figure 1 The air inlet 10a is located on the end face of the handle 10 away from the heat pipe 20.

[0032] In this embodiment, the air inlet 10a is located on the end face of the handle 10 away from the heat dissipation pipe 20. Thus, the air inlet 10a and the heat dissipation pipe 20 are located at opposite ends of the handle 10, forming a straight, continuous airflow with air entering from one end and exiting from the other. After entering from the free end face of the handle 10, the air flows completely along the length of the handle 10's accommodating space, passing over the entire surface of the movement assembly 11, maximizing contact with the heat-generating area for sufficient heat absorption. The hot air then directly enters the flow channel of the heat dissipation pipe 20 at the other end, avoiding insufficient heat absorption or heat residue caused by airflow bends, further improving heat dissipation efficiency. This ensures that air can remove heat from the handle 10 as quickly as possible. At the same time, the air inlet 10a is located on the opposite side of the treatment end and the grip end of the handle 10. The end of the handle 10 is the core area for medical staff to hold. The air inlet 10a is located on the end of the handle 10 away from the heat dissipation pipe 20, which can prevent fingers from blocking the airflow when holding it. It will not change the smoothness of the side of the handle 10 and affect the grip feel. At the same time, the opposite side of the air inlet end and the treatment end end will not allow the airflow to be directed directly towards the patient's lesion area, avoiding blowing away the coupling agent, cooling the skin around the lesion, or causing discomfort to the patient, thus ensuring the stability of treatment.

[0033] In one embodiment of this utility model, please refer to Figure 3 The treatment handpiece 100 also includes a socket 30 and a first cooling fan 40. The socket 30 is used to connect the treatment host, and the first cooling fan 40 is disposed in the socket 30. The socket 30 has a first air outlet 30a, and the other end of the heat dissipation pipe 20 is inserted into the socket 30 to connect the first cooling fan 40. The air inlet 10a, the flow channel of the heat dissipation pipe 20 and the first air outlet 30a are connected in sequence to form a heat dissipation air duct.

[0034] In this embodiment, the treatment handpiece 100 constructs a heat dissipation duct for the independent handle 10 by adding a socket 30 and a first cooling fan 40. Specifically, the socket 30 serves as an electrical connection carrier to achieve electrical connection with the handle 10 and the treatment host, thereby providing working power to the core assembly 11 and powering the first cooling fan 40. It also serves as the terminal carrier of the heat dissipation duct, with the built-in first cooling fan 40 providing independent active driving force. The socket 30 is provided with a first air outlet 30a as a hot air exhaust channel. The other end of the heat dissipation pipe 20 is inserted into the socket 30 and connected to the first cooling fan 40, so that the air inlet 10a, the receiving space of the handle 10 (which absorbs heat through the surface of the core assembly 11), the flow channel of the heat dissipation pipe 20, the first cooling fan 40, and the first air outlet 30a of the socket 30 are connected in sequence to form a complete closed-loop heat dissipation duct.

[0035] When the treatment handpiece 100 is in operation, the first cooling fan 40 generates negative or positive pressure. Air enters from the air inlet 10a away from the heat dissipation pipe 20 on the handle 10, flows along the length of the handle 10 through the core assembly 11 to absorb working heat, and then the hot air is quickly guided into the socket 30 through the flow channel of the heat dissipation pipe 20, and finally discharged directly to the external environment through the first air outlet 30a. The entire airflow path is straight and unobstructed, and the first cooling fan 40 is independent of the treatment host, so that the treatment handpiece 100 can achieve efficient heat dissipation without relying on the host's second cooling fan, adapting to more usage scenarios (such as when the host and the handpiece are far apart, or when multiple handpieces need to work simultaneously). At the same time, the socket 30 integrates electrical connection and heat dissipation functions, with a compact structure that does not increase the volume of the handle 10. The heat dissipation pipe 20 serves as both an air duct carrier and a connection fixation function, ensuring the grip comfort of the handle 10 and avoiding electrical wiring and The mutual interference of the heat dissipation air ducts further optimizes heat dissipation efficiency and ease of use. At the same time, the first heat dissipation fan 40 is located at the socket 30, which serves as the connection end component of the handle 10. It is far away from the gripping area of ​​medical staff and the treatment area of ​​the patient's lesion. The airflow discharged from its first air outlet 30a will not blow directly onto the hands of medical staff, nor towards the treatment area of ​​the patient, thus avoiding interference from the airflow at the outlet. In addition, the fact that the first heat dissipation fan 40 is located in the socket 30 instead of in the handle 10 can reduce the weight of the handle 10. When the user holds the handle 10, the grip force can be reduced, and the user will not experience soreness or fatigue due to the excessive weight of the handle 10. Even during long-term operation, the grip stability and treatment accuracy can be maintained. Especially in scenarios that require fine adjustment of the treatment angle and continuous aiming at the lesion, the weight reduction of the handle 10 can significantly reduce the operating burden of medical staff and improve the efficiency of diagnosis and treatment.

[0036] In one embodiment of this utility model, reference is made to Figure 2 The movement assembly 11 is located within the heat dissipation duct, and the projection of the movement assembly on the plane where the air inlet is located is located in the middle of the air inlet 10a.

[0037] In this embodiment, the core assembly 11 is a xenon lamp assembly, including a xenon lamp, electrodes, and other heat-generating components. The xenon lamp assembly is elongated and located within a heat dissipation duct, with one end facing the air inlet. Figure 2As shown, the xenon lamp assembly has a long, strip-shaped design, extending along the left and right directions. An air inlet 10a is located in the direction extending to the right. The area of ​​the air inlet 10a is larger than the cross-sectional area of ​​the xenon lamp assembly in the left-right direction, and the projection of the xenon lamp assembly in this direction is located in the middle of the air inlet 10a. Therefore, when the first cooling fan 40 is activated, air enters the cooling duct through the air inlet 10a, moves to the left, and upon encountering the xenon lamp assembly, disperses from the top, bottom, front, and rear perimeters of the xenon lamp before flowing to the left again, entering the heat dissipation pipe 20. After passing through the first cooling fan 40, it exits through the first air outlet 30a, completing the cooling of the xenon lamp assembly. This allows the air entering through the air inlet 10a to envelop the xenon lamp assembly, maximizing the contact area and increasing cooling efficiency.

[0038] In one embodiment of the present invention, the portion of the handle near the heat dissipation pipe 20 is flared.

[0039] In this embodiment, the cooling duct is the space within the handle where air flows. Air enters the cooling duct from the air inlet 10a, then flows out of the cooling duct and into the heat dissipation pipe 20a. The part of the handle 10 near the heat dissipation pipe 20a has a flared design, meaning this part of the cooling duct is flared in shape. This allows the air dissipating heat from the mechanism assembly 11 around its perimeter to converge at the wider end of the flared end and flow into the narrower end before entering the heat dissipation pipe 20a, improving airflow efficiency. This prevents air from circulating around the mechanism assembly 11, which would reduce cooling efficiency.

[0040] In one embodiment of this utility model, please refer to Figure 3 The socket 30 has a power-connecting side and an air-discharge side, and the power-connecting side and the air-discharge side of the socket 30 are respectively arranged on the socket 30. The first cooling fan 40 is located between the power-connecting side and the air-discharge side of the socket 30; the first air outlet 30a is located on the air-discharge side of the socket 30.

[0041] In this embodiment, the air outlet side and the power connection side of the socket 30 are located on the upper and lower sides of the socket 30 along the vertical direction. The power connection side is the side of the socket 30 with pins, which are used to connect the treatment host to achieve electrical connection. The first cooling fan 40 is located between the power connection side and the air outlet side of the socket 30 along the vertical direction. The first air outlet 30a is located on the air outlet side of the socket 30. When the treatment handpiece 100 is in working state, the first cooling fan 40 starts and forms a directional airflow, driving air to enter from the air inlet 10a away from the heat dissipation pipe 20 of the handle 10, and flow completely along the accommodating space of the handle 10. Heat is absorbed by the core assembly 11, and the hot air is introduced into the socket 30 through the heat dissipation pipe 20 flow channel. Under the guidance of the fan, it flows from the power connection side to the air outlet side, and is finally discharged upward through the first air outlet 30a on the air outlet side. While achieving directional exhaust, it can also remove the heat generated by the first cooling fan 40 when it is working and the additional heat generated by the electrical connection of the socket 30, so as to avoid the heat accumulation of the fan and the socket 30 affecting the working stability. At the same time, the upward air outlet direction is away from medical staff and patients, and the exhaust air will not blow towards medical staff and patients, thereby avoiding the interference of the air outlet airflow to users.

[0042] In one embodiment of this utility model, please refer to Figure 1 and Figure 3 The treatment handpiece 100 also includes a power supply cable 50, a power supply cable 50 electrical connection socket 30 and a handle 10, and a heat dissipation pipe 20 sleeved on the outer periphery of the power supply cable 50.

[0043] In this embodiment, the power supply cable 50 serves as an electrical transmission carrier, with one end electrically connected to the socket 30 and the other end electrically connected to the handle 10. When the socket 30 is plugged into the treatment host, the power supply cable 50 can transmit working power to the core component 11 inside the handle 10. The heat dissipation pipe 20 is sleeved around the power supply cable 50, forming a structure of "cable in the center and air duct around", which can avoid the entanglement and pulling problems caused by the dispersed arrangement of the power supply cable 50 and the heat dissipation pipe 20, and improve the ease of operation and structural stability. When the treatment handpiece 100 is in operation, air enters from the air inlet 10a at the far end of the handle 10, flows through the core assembly 11 to absorb heat, and is then directed into the socket 30 along the flow channel of the heat dissipation pipe 20 (encircling the outer periphery of the power supply cable 50). Driven by the first cooling fan 40, the air is discharged upward from the first air outlet 30a on the air outlet side. This not only achieves rapid heat dissipation from the core assembly, but also simultaneously removes the small amount of additional heat generated by the power supply cable 50 during operation, preventing heat accumulation in the cable from affecting insulation performance or power transmission stability. At the same time, the heat dissipation pipe 20 provides physical protection for the power supply cable 50, reducing damage to the cable caused by friction and bending during use.

[0044] In one embodiment of this invention, the heat dissipation pipe 20 is a corrugated pipe. The corrugated pipe connects the handle 10 and the socket 30, and can extend, retract, and bend to accommodate the movement of the handle 10 relative to the socket 30, preventing pipe breakage or leakage due to movement. Furthermore, since a first cooling fan 40 is installed on the socket 30, the first cooling fan 40 will generate some vibration during operation. The corrugated pipe can absorb the vibration energy generated by the first cooling fan 40 during operation, reducing noise propagation and mechanical stress transmission. In addition, the flexible structure of the corrugated pipe can reduce turbulence and pressure fluctuations of the internal airflow, thus reducing noise.

[0045] In one embodiment of this utility model, please refer to Figure 2 and Figure 3 The treatment handpiece 100 also includes a first sealing component 60, which includes a first fixing seat 61 and a first clamp 62. The first fixing seat 61 is fixedly connected to the first cooling fan 40. One end of the cooling pipe 20 is sleeved on the outer periphery of the first fixing seat 61, and the first clamp 62 is fixedly installed on the outer periphery of the cooling pipe 20 corresponding to the first fixing seat 61, so that the cooling pipe 20 is sealed to the first fixing seat 61.

[0046] In this embodiment, the first sealing component 60 serves as a transitional structure connecting the heat dissipation pipe 20 and the first cooling fan 40. The first fixing seat 61 is directly fixedly connected to the first cooling fan 40 by means of screwing, welding, bonding, or integral molding. After one end of the heat dissipation pipe 20 is sleeved on the outer periphery of the first fixing seat 61, a first clamp 62 is fixedly installed on the heat dissipation pipe 20 corresponding to the outer periphery of the first fixing seat 61. The tightening force of the first clamp 62 makes the inner wall of the heat dissipation pipe 20 fit tightly with the outer periphery of the first fixing seat 61, forming a reliable sealing connection. The first fixing seat 61 has a hollow structure with open ends at both ends, so that the two ends of the first fixing seat 61 can connect the air cavity of the first cooling fan 40 and the flow channel of the heat dissipation pipe 20, thereby realizing air flow.

[0047] By setting the first sealing component 60, the sealed connection between the heat dissipation pipe 20 and the first fixed base 61 can prevent airflow leakage at the connection point of the heat dissipation duct. This ensures that after the air enters from the air inlet 10a of the handle 10, it flows directionally along the flow channel of the heat dissipation pipe 20 to the first heat dissipation fan 40 without bypassing or losing air, thus ensuring the concentration and flow rate of the heat dissipation airflow. At the same time, the connection between the heat dissipation pipe 20 and the first heat dissipation fan 40 through the first sealing component 60 can prevent water stains or debris entering from the air inlet 10a from entering the interior of the socket 30 through the connection point, thus avoiding contamination of the electrical components of the socket 30, reducing the risk of equipment failure, and extending the service life.

[0048] In one embodiment of this utility model, please refer to Figure 1 and Figure 3The treatment handpiece 100 also includes a second sealing component 70, which includes a second fixing seat 71 and a second clamp 72. The second fixing seat 71 is disposed in the handle 10, and the other end of the heat dissipation pipe 20 is sleeved on the outer periphery of the second fixing seat 71. The second clamp 72 is fixedly disposed on the outer periphery of the heat dissipation pipe 20 corresponding to the second fixing seat 71, so that the heat dissipation pipe 20 and the second fixing seat 71 are sealed together.

[0049] In this embodiment, the second fixing seat 71 is disposed inside the handle 10, providing a precise installation positioning reference for the heat dissipation pipe 20. After one end of the heat dissipation pipe 20 is sleeved on the outer periphery of the second fixing seat 71, the second clamp 72 is fixedly installed on the heat dissipation pipe 20 corresponding to the outer periphery of the second fixing seat 71. The radial fastening force of the second clamp 72 makes the inner wall of the heat dissipation pipe 20 fit tightly with the outer periphery of the second fixing seat 71, forming a gapless sealed connection. At the same time, the second fixing seat 71 has a hollow structure with open ends at both ends, so that the two ends of the second fixing seat 71 can connect the receiving space of the handle 10 and the flow channel of the heat dissipation pipe 20, thereby realizing air flow.

[0050] By setting the second sealing component 70, airflow leakage at the connection between the heat dissipation pipe 20 and the handle 10 can be avoided, ensuring that after the air enters from the air inlet 10a of the handle 10, it can be directionally transmitted along the flow channel of the heat dissipation pipe 20 without bypassing or loss, thus ensuring the concentration and flow rate of the heat dissipation airflow.

[0051] In one embodiment of this utility model, please refer to Figure 4 The treatment handpiece 100 also includes a fan mounting base 80 and a first noise reduction and vibration damping component 81. The fan mounting base 80 is located inside the socket 30, and the first heat dissipation fan 40 is located in the fan mounting base 80. The first mounting base 61 is connected to the fan mounting base 80. The first noise reduction and vibration damping component 81 is located on the inner peripheral wall of the fan mounting base 80, and the outer peripheral wall of the first heat dissipation fan 40 abuts against the first noise reduction and vibration damping component 81.

[0052] In this embodiment, the fan mounting base 80 is composed of two symmetrical half-shells, both of which are open ends. The first mounting base 61 is connected to the fan mounting base 80 by means of screwing, welding, bonding, integral molding, etc. The heat dissipation pipe 20 is sleeved on the first mounting base 61 and exposed on the outer periphery of the fan mounting base 80. The other end of the fan mounting base 80 is connected to the air outlet of the socket 30, thereby realizing air flow.

[0053] The first cooling fan 40 is fixed in the fan mounting base 80. A first noise-reducing and vibration-damping component 81, made of silicone, sponge, or similar materials, is embedded in the inner cavity of the fan mounting base 80. The first noise-reducing and vibration-damping component 81 is attached to the inner circumferential surface of the fan mounting base 80 by adhesive or other means. The outer circumferential wall of the first cooling fan 40 abuts against the first noise-reducing and vibration-damping component 81. When the cooling fan is in operation, its high-speed motor rotation generates vibration, and the airflow within the fan cavity and duct causes airflow disturbance noise. The first noise-reducing and vibration-damping component 81, due to its elastic properties, can effectively absorb the noise generated by the fan. The vibration energy generated by the rotation is prevented from being transmitted through the fan mounting base 80 to the socket 30, heat dissipation pipe 20 and handle 10, thus preventing medical staff from feeling significant vibration when holding the handle 10. This ensures grip stability and operational accuracy, while also reducing long-term wear and tear on the electrical components inside the socket 30 and the internal mechanism components 11 inside the handle 10, extending the service life of the equipment. At the same time, materials such as silicone and sponge have good sound absorption properties, which can absorb the noise generated by the operation of the fan and the flow of air, reduce noise interference in the treatment environment, and improve the user experience for medical staff and patients.

[0054] In one embodiment of this utility model, please refer to Figure 5 The fan mounting base 80 also includes a mounting post 90 and a second noise reduction and vibration damping component 91. The second noise reduction and vibration damping component 91 is sleeved on the outer periphery of the mounting post 90. The mounting post 90 is fixedly connected to the socket 30. The second noise reduction and vibration damping component 91 is located between the mounting post 90 and the socket 30.

[0055] In this embodiment, the bottom of the fan mounting base 80 is provided with multiple fixing posts 90, and the socket 30 is provided with a number of holes corresponding to the number of fixing posts 90. Each fixing post 90 is inserted into one hole, thereby fixing the fan mounting base 80 in the socket 30. Alternatively, the end of the fixing post 90 is provided with an internal thread structure, and the fixing post 90 is screwed to the bottom of the socket 30 by screws, bolts, or other structures, thereby fixing the fan mounting base 80. A second noise reduction and vibration damping component 91 is sleeved on the outer periphery of each fixing post 90. The second noise reduction and vibration damping component 91 is made of materials such as silicone and sponge. When the cooling fan is in working condition, the vibration generated by its high-speed motor rotation is first initially absorbed by the first noise reduction and vibration damping component 81 on the inner periphery of the fan mounting base 80. The remaining unabsorbed vibration is transmitted to the fan mounting base 80, at which time the second noise reduction and vibration damping component 91 is activated. The shock absorber 91, with its elastic properties, further buffers and absorbs this vibration energy, completely blocking the transmission path of vibration through the fixed column 90 to the socket 30, heat dissipation pipe 20, and handle 10. This not only avoids medical staff feeling significant vibration when holding the handle 10, ensuring the accuracy and stability of treatment operations, but also reduces the mechanical wear of electrical connection components in the socket 30, the internal mechanism 11 in the handle 10, and the power supply cable 50 caused by long-term vibration, extending the overall service life of the equipment. At the same time, the second noise reduction shock absorber 91 works in synergy with the first noise reduction shock absorber 81, not only forming "double protection" on the vibration transmission path, but its elastic material can also help absorb some of the noise generated by the operation of the fan and the flow of air, further reducing noise interference in the treatment environment and improving the user experience for medical staff and patients.

[0056] This utility model also proposes a medical device, which includes a treatment host and a treatment handpiece 100 as described above. The handle 10 is electrically connected to the treatment host. In one embodiment, one end of the heat dissipation pipe 20 is connected to the handle 10 and the other end is connected to the treatment host. At the same time, the treatment host is provided with a second heat dissipation fan and a second air outlet. Thus, under the action of the second heat dissipation fan, the air entering from the air inlet 10a of the handle 10 can be discharged sequentially through the flow channel of the heat dissipation pipe 20 and the second air outlet of the treatment host, thereby forming a heat dissipation air duct that can dissipate heat and cool down the core component 11.

[0057] In another embodiment, the treatment handpiece 100 includes a handle 10, a heat dissipation pipe 20, a socket 30, and a first cooling fan 40. The handle 10 is electrically connected to the socket 30 via a power supply cable 50. The first cooling fan 40 is located inside the socket 30. One end of the heat dissipation pipe 20 is connected to the handle 10, and the other end passes through the socket 30 and is connected to the first cooling fan 40. The socket 30 is provided with a first air outlet 30a. Thus, under the action of the first cooling fan 40, the air entering from the air inlet 10a of the handle 10 can be discharged sequentially through the flow channel of the heat dissipation pipe 20 and the first air outlet 30a of the socket 30, thereby forming a heat dissipation air duct that can dissipate heat and cool down the core component 11.

[0058] Based on the above two embodiments, the specific structure of the treatment handpiece 100 is as described in the above embodiments. Since the medical device proposed by this utility model adopts all the technical solutions of 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 described in detail here.

[0059] The above are merely exemplary embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the technical concept of this utility model and the contents of the specification and drawings of this utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
