Description

Technical Field

[0001] This utility model relates to the field of treatment equipment technology, and in particular to a radiofrequency treatment handpiece and radiofrequency treatment device. Background Technology

[0002] Radiofrequency treatment handpieces apply radiofrequency energy to the treatment site through electrodes to achieve the purpose of treatment. Since the shape and size of different treatment sites and the same treatment site (such as the vagina and urethra) vary from patient to patient, the electrodes in the radiofrequency treatment handpiece are often designed to be detachably connected to the housing, so as to facilitate the removal and replacement of the electrodes.

[0003] To facilitate quick assembly and disassembly of the electrode and the housing, the electrode is usually equipped with a locking block or slot to engage with the housing. However, during the manufacturing process, the locking block and slot may inevitably have manufacturing errors, which may result in the locking block and slot not fitting tightly. This can lead to a loose connection between the electrode and the housing, and the electrode head may wobble slightly during treatment. Utility Model Content

[0004] The main purpose of this invention is to provide a radiofrequency therapy handpiece and radiofrequency therapy device, which aims to solve the problem of electrode head wobbling.

[0005] To achieve the above objectives, the radiofrequency therapy handpiece proposed in this utility model includes a housing, an electrode head, and an elastic element. The housing is provided with a mating interface. The electrode head includes a treatment part and a connecting part protruding from the treatment part. One of the peripheral sidewall of the connecting part and the inner peripheral wall of the mating interface is recessed with a slot, and the other is protruding with a locking block. The connecting part is inserted into the mating interface, and the locking block is inserted into the slot to engage the electrode head with the housing. The elastic element is disposed in the mating interface and abuts against the electrode head. The elastic element is used to apply an outward pushing force to the electrode head.

[0006] In one embodiment, the radiofrequency treatment handpiece further includes a temperature sensing component disposed at one end of the elastic member facing the electrode head, the elastic member applying a thrust to the electrode head via the temperature sensing component.

[0007] In one embodiment, the axis of the temperature measuring component is coaxial with the axis of the electrode head.

[0008] In one embodiment, the connecting portion is provided with an installation channel, and both the elastic member and the temperature measuring component are disposed in the installation channel. The temperature measuring component is disposed at the end of the elastic member facing the treatment portion to apply a thrust to the treatment portion.

[0009] In one embodiment, the radiofrequency treatment handle further includes a sleeve that passes through the interface and is connected to the housing. An opening is provided at one end of the sleeve facing the treatment part. An elastic element is disposed inside the sleeve, and a temperature measuring component passes through the opening and is connected to the elastic element.

[0010] In one embodiment, the temperature measuring component includes a heat-conducting element and a temperature sensor. The heat-conducting element passes through the opening and is connected to the elastic element. The temperature sensor is disposed inside the heat-conducting element. The heat-conducting element pushes against the treatment part under the action of the elastic element.

[0011] In one embodiment, the treatment part has a recessed abutment groove on the side facing the heat conductor, the abutment groove being directly opposite the heat conductor, the cross-sectional dimensions of the abutment groove gradually decreasing from the end facing the heat conductor to the end away from the heat conductor, and the heat conductor has a protruding abutment portion on the side facing the treatment part, the shape and size of the abutment portion matching the shape and size of the abutment groove.

[0012] In one embodiment, the heat-conducting component is made of metal, and the radiofrequency treatment handpiece also includes a main control board. The main control board is disposed in the cavity of the outer shell, and the heat-conducting component is electrically connected to the main control board through a wire. The heat-conducting component contacts the treatment part to realize electrical conduction between the electrode head and the main control board.

[0013] In one embodiment, the shape of the treatment part is one of a cone, a square, or a circle.

[0014] This utility model also proposes a radiofrequency therapy device, which includes a main unit and the radiofrequency therapy handle mentioned above, wherein the main unit is electrically connected to the radiofrequency therapy handle.

[0015] This radiofrequency therapy handpiece is equipped with an elastic element, which is placed inside the interface to connect with the electrode head. The elastic element is in a compressed state, which ensures that the elastic element always applies an outward pushing force to the electrode head. Under the elastic force of the elastic element, the electrode head tends to move outward, which can make part of the side wall of the locking block and part of the side wall of the locking slot tightly abut against each other, effectively preventing the electrode head from becoming loose or shaking.

[0028] This utility model proposes a radiofrequency therapy handpiece 100.

[0029] Please see Figures 1 to 5 An embodiment of the radiofrequency therapy handpiece 100 includes a housing 1, an electrode head 2, and an elastic element 3. The housing 1 is provided with a docking interface 11. The electrode head 2 includes a treatment part 21 and a connecting part 22 protruding from the treatment part 21. One of the peripheral sidewall of the connecting part 22 and the inner peripheral wall of the docking interface 11 is recessed with a slot 222, and the other is protruding with a locking block 13. The connecting part 22 is inserted into the docking interface 11, and the locking block 13 is inserted into the slot 222 to realize the locking of the electrode head 2 and the housing 1. The elastic element 3 is disposed in the docking interface 11 and connected to the electrode head 2. The elastic element 3 is used to apply an outward pushing force to the electrode head 2 to prevent the electrode head 2 from shaking.

[0030] To facilitate the disassembly and replacement of the electrode head 2, this radiofrequency therapy device features a snap-fit ​​connection between the electrode head 2 and the outer casing 1. Specifically, the outer casing 1 is provided with a mating interface 11. The electrode head 2 includes a treatment section 21 and a connecting section 22 protruding from the treatment section 21. Figure 3 and Figure 5 As shown, the outer periphery of the connecting part 22 is recessed with several slots 222, which are evenly arranged in the circumferential direction of the connecting part 22. The inner periphery of the interface 11 is provided with protruding blocks 13, the number of which is the same as the number of slots 222, and the recess depth of the blocks 13 is the same as the recess depth of the slots 222. When assembling the electrode head 2 with the outer shell 1, the connecting part 22 of the electrode head 2 is inserted into the interface 11, and each block 13 is inserted into a slot 222 to achieve the snap-fit ​​between the electrode head 2 and the outer shell 1. Of course, the same snap-fit ​​effect can be achieved by interchangeing the positions of the slots 222 and the blocks 13. The slots 222 are concave hemispherical, and the blocks 13 are convex hemispherical; the two can be snapped together through an interference fit.

[0031] During treatment, the treatment portion 21 of the electrode head 2 contacts and adheres to the skin for radiofrequency treatment. Inevitably, processing errors may occur during the manufacturing process of the locking block 13 and the slot 222, resulting in gaps between the sidewalls of the locking block 13 and the slot 222. This can cause loosening of the connection between the electrode head 2 and the outer shell 1, leading to the electrode head 2 easily wobbling during treatment. To avoid this problem, the radiofrequency treatment handle 100 is equipped with an elastic element 3, such as a spring or rubber pad. The elastic element 3 is located within the interface 11 and connected to the electrode head 2, and is in a compressed state. This ensures that the elastic element 3 always applies an outward pushing force to the electrode head 2. Under the elastic force of the elastic element 3, the electrode head 2 tends to move outward, allowing a portion of the sidewall of the locking block 13 to abut against a portion of the sidewall of the slot 222, effectively preventing the electrode head 2 from loosening and wobbling.

[0032] It is easy to understand that radiofrequency energy applied to the skin will cause the skin to generate heat. If the heat is too low, the treatment effect will be weakened, and if the heat is too high, burns will occur. In order to perform real-time temperature detection on the treated skin, this radiofrequency treatment handpiece 100 also includes a temperature measuring component 4. The temperature measuring component 4 is located at the end of the elastic member 3 facing the electrode head 2. The elastic member 3 applies a pushing force to the electrode head 2 through the temperature measuring component 4.

[0033] During treatment, skin temperature is transferred to electrode head 2, and then to temperature measuring component 4, thereby enabling skin temperature detection. Temperature measuring component 4 not only monitors skin temperature, ensuring it remains within a safe and effective range, but also, by positioning it at the end of elastic member 3 facing electrode head 2, it performs the dual functions of temperature measurement and applying thrust. This improves the utilization rate of temperature measuring component 4, reduces the space occupied by both component 4 and elastic member 3, and makes the structure at the connection between outer shell 1 and electrode head 2 more compact.

[0034] The fact that the axis of the temperature measuring component 4 is coaxial with the axis of the electrode head 2 ensures that the thrust of the temperature measuring component 4 on the treatment part 21 is along the axial direction, thereby reducing the lateral force on the electrode head 2 and reducing shaking.

[0035] Reference Figure 2 In one embodiment of the present invention, an installation channel 221 is provided in the connecting part 22 of the electrode head 2. The axis of the installation channel 221 is coaxial with the axis of the treatment part 21. The elastic member 3 and the temperature measuring component 4 are both provided in the installation channel 221. The temperature measuring component 4 is provided at the end of the elastic member 3 facing the treatment part 21 to apply a pushing force to the treatment part 21.

[0036] In this embodiment, an installation channel 221 is provided in the connection part 22 of the electrode head 2, and the elastic element 3 and the temperature measuring component 4 are both arranged in the installation channel 221. This allows the temperature measuring component 4 to be closer to the treatment part 21, thereby reducing heat loss during the transfer process and making the temperature measured by the temperature measuring component 4 closer to the skin temperature, thus improving the accuracy of temperature measurement.

[0037] Furthermore, the radiofrequency treatment handpiece 100 also includes a sleeve 5, which passes through the interface 11 and is connected to the housing 1. An opening is provided at the end of the sleeve 5 facing the treatment section 21. An elastic element 3 is disposed within the sleeve 5, and a temperature sensing component 4 passes through the opening and is connected to the elastic element 3. In this case, the temperature sensing component 4 can extend and retract along the axial direction of the opening, thereby adapting to the assembly requirements of electrode heads 2 of different thicknesses and improving the versatility and flexibility of the device.

[0038] The temperature measuring component 4 includes a heat-conducting element 41 and a temperature sensor 42. The heat-conducting element 41 passes through the opening and is connected to the elastic element 3. The temperature sensor 42 is disposed inside the heat-conducting element 41. Under the action of the elastic element 3, the heat-conducting element 41 pushes against the treatment part 21. Skin temperature is transmitted to the electrode head 2, and then through the heat-conducting element 41 to the temperature sensor 42, thereby realizing the detection of skin temperature.

[0039] The heat-conducting component 41 is made of metal, enabling it to conduct electricity while maintaining thermal conductivity, thus achieving electrical connection with the electrodes. Specifically, the radiofrequency treatment handpiece 100 also includes a main control board 6, which is located within the cavity of the outer casing 1. The heat-conducting component 41 is electrically connected to the main control board 6 via a wire 7, and the heat-conducting component 41 contacts the treatment part 21, thereby achieving electrical connection between the electrode head 2 and the main control board 6. Thus, the temperature sensing component 4 not only transfers heat but also serves to ensure electrical connection between the electrode head 2 and the main control board 6, allowing current to flow smoothly and guaranteeing the effective transfer of radiofrequency energy.

[0040] Furthermore, the treatment section 21 has a recessed abutment groove 211 on the side facing the heat-conducting element 41. The abutment groove 211 is directly opposite the heat-conducting element 41. The cross-sectional dimensions of the abutment groove 211 gradually decrease from the end facing the heat-conducting element 41 to the end away from the heat-conducting element 41. The side of the heat-conducting element 41 facing the treatment section 21 has a protruding abutment portion. The shape and size of the abutment portion match the shape and size of the abutment groove 211. The shape of the abutment groove 211 can be hemispherical, conical, or bowl-shaped, etc. Since the cross-sectional dimensions of the abutment groove 211 gradually decrease from the end facing the heat-conducting element 41 to the end away from the heat-conducting element 41, the abutment groove 211 has a corrective effect on the heat-conducting element 41. In this way, even if there is a slight deviation in the installation position of the heat-conducting element 41 and the electrode head 2, the abutment groove 211 can guide the heat-conducting element 41 to automatically correct its coaxiality with the electrode head 2, ensuring that the axis of the heat-conducting element 41 is coaxial with the axis of the electrode head 2, thus ensuring the reliability of the connection.

[0041] Reference Figure 2 To facilitate the installation of the elastic element 3, a base 8 is provided at the end of the sleeve 5 facing away from the heat-conducting element 41. The elastic element 3 is disposed inside the sleeve 5, and the end of the elastic element 3 facing away from the heat-conducting element 41 is connected to the base 8. The base 8 provides support for the elastic element 3, thereby ensuring that the elastic element 3 maintains the correct position and orientation within the sleeve 5.

[0042] In one embodiment, the plane on which the main control board 6 is located is perpendicular to the axis of the sleeve 5, and a spring pin 9 is provided between the base 8 and the main control board 6. The base 8 is connected to the main control board 6 through the spring pin 9.

[0043] In this embodiment, the base 8 is connected to the main control board 6 via a spring pin 9. Since the spring pin 9 has a certain telescopic performance, the base 8 and the sleeve 5 connected to the base 8 are allowed to telescopic within a certain range, so that the radiofrequency treatment handle 100 can adapt to the assembly requirements of electrode heads 2 with greater thickness, thereby further improving the versatility and flexibility of the device.

[0044] In order to limit the sleeve 5 and prevent the sleeve 5 from falling out of the interface 11, a first protruding ring 12 is provided on the inner peripheral wall of the interface 11, and a second protruding ring 51 is provided on the outer peripheral wall of the sleeve 5. The second protruding ring 51 is located on the side of the first protruding ring 12 facing the main control board 6. The first protruding ring 12 is used to abut against the second protruding ring 51 to limit the movement, thereby ensuring that the sleeve 5 can be stably fixed in the interface 11.

[0045] In the embodiment shown in the figure, a narrow first cavity is provided at the end of the heat-conducting element 41 facing the treatment section 21. The first cavity is filled with thermally conductive silicone grease, and the temperature sensor 42 is immersed in the thermally conductive silicone grease. As a highly efficient heat conduction medium, the thermally conductive silicone grease can ensure that the heat transfer from the treatment section 21 to the temperature sensor 42 is more rapid and uniform, enabling the temperature sensor 42 to more stably sense the temperature changes of the treatment section 21.

[0046] Meanwhile, a second cavity is provided at one end of the heat-conducting component 41 away from the treatment section 21. The second cavity is connected to the first cavity and the chamber of the sleeve 5, and the cross-sectional dimension of the second cavity is larger than that of the first cavity. A sealing plug 43 is provided inside the second cavity to prevent leakage of thermal grease. At this time, a wire passage is provided on the sealing plug 43, and the wire 7 passes through the wire passage to connect the temperature sensor 42 and the main control board 6.

[0047] Reference Figure 1 This radiofrequency treatment handpiece 100 is equipped with multiple electrode heads 2, the treatment portion 21 of which is one of a conical, square, or circular shape. Different shapes of electrode heads 2 can meet the treatment needs of different treatment portions 21. For example, a conical electrode head 2 is suitable for situations requiring gradual penetration into the skin, such as vaginal or urethral treatment; a square electrode head 2 is suitable for treatments requiring large-area contact; and a circular electrode head 2 is suitable for small-area treatments. Users can select the appropriate electrode head 2 shape according to the characteristics of different treatment portions 21, thus enabling this radiofrequency treatment handpiece 100 to be applied to a variety of different treatment scenarios.
