Description

Technical Field

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

[0002] Currently, most high-frequency therapeutic products automatically determine whether to activate by detecting whether the treatment head is in contact with the treatment surface. This contact detection is primarily achieved using capacitive contact sensors or photosensitive sensors. However, both methods have limitations. For example, in high-frequency therapeutic devices that simultaneously output ultrasound and radiofrequency energy, an ultrasound coupling agent (gel) needs to be coated on the treatment surface to conduct the ultrasound energy to the subcutaneous layer, as the ultrasound energy requires a conductive medium. However, devices using capacitive contact sensors are prone to false triggering; the sensor may be falsely activated upon contact with the medical gel, causing the treatment head to activate even when it is not in contact with the treatment surface. Furthermore, in dark or low-light environments, photosensitive sensors may malfunction or have insufficient accuracy, preventing the treatment head from determining activation based on contact with the treatment surface. Summary of the Invention

[0017] In one embodiment, the treatment head further includes a temperature detection sensor connected to the electrode structure and spaced apart from the deformation detection sensor, the temperature detection sensor being used to detect the temperature of the electrode structure.

[0018] In one embodiment, the electrode structure is bonded to the housing.

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0034] In related technologies, high-frequency therapeutic devices often use capacitive contact sensors or photosensitive sensors to detect contact between the treatment head and the treatment surface. When the treatment head and treatment surface come into contact, the capacitive contact sensor or photosensitive sensor is triggered, and the therapeutic device controls the operation of the treatment head. For example, in high-frequency therapeutic devices that simultaneously output ultrasound and radiofrequency energy, since the conduction of ultrasound energy requires a sound-conducting medium, an ultrasound coupling agent (gel) is applied to the skin to facilitate the conduction of ultrasound energy to the subcutaneous layer. However, therapeutic devices using capacitive contact sensors are prone to false triggering; the capacitive contact sensor is easily triggered when it comes into contact with the medical gel, causing the therapeutic head to start operating even when it is not in contact with the treatment surface. In environments with insufficient light, the photosensitive sensor cannot function properly, causing the therapeutic device to lose its contact detection function between the treatment head and the treatment surface.

[0035] Based on the above issues and ideas, please refer to the following: Figures 1 to 7 As shown, the present invention proposes a treatment head 100, which includes a housing 1, a control plate 6, an electrode structure 2, and a deformation detection sensor 3. The housing 1 encloses and forms a mounting cavity 15; the control plate 6 is disposed in the mounting cavity 15; the electrode structure 2 is connected to the end of the housing 1 and is electrically connected to the control plate 6; the deformation detection sensor 3 is electrically connected to both the electrode structure 2 and the control plate 6, and is used to detect the deformation of the electrode structure 2 and transmit a deformation signal to the control plate 6. The control plate 6 is used to control the electrode structure 2 to emit electrical energy according to the received deformation signal.

[0036] In this embodiment, the electrode structure 2 is connected to the housing 1, which provides support for the electrode structure 2. The control plate 6 is disposed in the mounting cavity 15 formed by the housing 1 to isolate the control plate 6 from the outside environment, thereby protecting the control plate 6 and reducing the possibility of damage to the control plate 6. When the treatment head 100 performs treatment, the electrode structure 2 comes into contact with the treatment surface, and the electrode structure 2 undergoes slight deformation under pressure. The deformation detection sensor 3 detects the slight deformation of the electrode structure 2 and transmits the deformation signal to the control plate 6. The control plate 6 controls the electrode structure 2 to emit electrical energy to treat the treatment surface. This triggering method of the electrode structure 2 is not affected by the ambient brightness or whether the treatment surface is coated with medical gel or other coatings, which greatly improves the applicability and accuracy of the contact detection between the treatment head 100 and the treatment surface.

[0037] Optionally, the housing 1 is provided with a receiving groove, and at least a portion of the electrode structure 2 is confined within the receiving groove to facilitate the positioning and installation of the electrode structure 2; the deformation detection sensor 3 may be located at any position within the electrode structure 2, the control board 6, or the mounting cavity 15, without specific limitations.

[0038] In one embodiment of the present invention, such as Figures 2 to 6As shown, the electrode structure 2 has a first surface 21 and a second surface 22 that are opposite to each other. The first surface 21 is used to contact the treatment surface. The deformation detection sensor 3 is located on the second surface 22. The second surface 22 is connected to the housing 1. The housing 1 has a relief cavity 12 corresponding to the deformation detection sensor 3. The deformation detection sensor 3 is suspended in the relief cavity 12.

[0039] In this embodiment, the first surface 21 of the electrode structure 2 is used to abut against the treatment surface, and the deformation detection sensor 3 is disposed on the second surface 22 of the electrode structure 2. Simultaneously, the deformation detection sensor 3 is suspended within the recessed cavity 12. When the electrode structure 2 contacts the treatment surface, it sends a deformation signal, causing the deformation detection sensor 3 to move into the recessed cavity 12. Thus, the recessed cavity 12 provides a certain deformation space for the electrode structure 2 and a certain displacement space for the deformation detection sensor 3, preventing the deformation detection sensor 3 from abutting against the cavity wall of the recessed cavity 12 and thus malfunctioning. When the first surface 21 contacts the treatment surface and rubs or is pressed, the electrode structure 2 deforms, triggering the deformation detection sensor 3 on the second surface 22. The deformation detection sensor 3 then sends a deformation signal to the control board 6, which controls the electrode structure 2 to begin treatment. By placing the deformation detection sensor 3 on the second surface 22 of the electrode structure 2, the signal transmission path between the electrode structure 2 and the deformation detection sensor 3 is shortened, thereby improving the immediacy and accuracy of the deformation detection sensor 3 in detecting the deformation of the electrode structure 2.

[0040] In actual implementation, when the treatment head 100 treats the treatment surface, it typically uses a stamping-style pressing method to ensure that the first surface 21 of the electrode structure 2 adheres to the treatment surface. This allows the electrode structure 2 to uniformly deliver electrical energy to the treatment surface, thereby ensuring the treatment effect. Therefore, when the electrode structure 2 contacts the treatment surface, the direction of the external force is mostly perpendicular to the first surface 21. By placing the deformation detection sensor 3 on the second surface 22, which is opposite to the first surface 21, the sensitivity of deformation detection of the electrode structure 2 can be improved without interfering with the first surface 21 adhering to the treatment surface.

[0041] In one embodiment of the present invention, such as Figures 4 to 6 As shown, both the deformation detection sensor 3 and the avoidance cavity 12 include multiple ones. Multiple deformation detection sensors 3 are spaced apart on the second surface 22. The avoidance cavity 12 is arranged in a one-to-one correspondence with the deformation detection sensor 3. Each deformation detection sensor 3 is suspended in an avoidance cavity 12.

[0042] In this embodiment, multiple deformation detection sensors 3 are spaced apart on the second surface 22 to ensure the accuracy of deformation detection of the electrode structure 2. Simultaneously, by analyzing the values ​​detected by the multiple deformation detection sensors 3, it can be determined whether the contact between the electrode structure 2 and the treatment surface has tilted or shifted. Furthermore, the contact angle between the electrode structure 2 and the treatment surface is adjusted in real time based on the detection values ​​of the multiple deformation detection sensors 3, thereby achieving the best treatment effect. The avoidance cavity 12 is configured in a one-to-one correspondence with the deformation detection sensor 3, ensuring that the housing 1 meets the avoidance requirements of the deformation detection sensor 3 while preventing the span of the avoidance cavity 12 from being too large, thus ensuring the supporting strength of the housing 1 for the electrode structure 2. It also increases the area of ​​the connection surface 11 with the electrode structure 2, thereby ensuring the connection strength with the electrode structure 2.

[0043] In actual implementation, the deformation detection sensor 3 can be one, two, three or other numbers. The deformation detection sensor 3 is arranged at intervals along the circumference of the electrode structure 2. The clearance cavity 12 is arranged in the shape of a groove or a through groove, which is not specifically limited here.

[0044] For example, four deformation detection sensors 3 are provided, and the four deformation detection sensors 3 are evenly spaced along the circumferential distance of the electrode structure 2. Four clearance cavities 12 are also provided, and the four clearance cavities 12 are evenly spaced along the circumferential distance of the housing 1.

[0045] In one embodiment of the present invention, such as Figure 2 , Figure 4 and Figure 7 As shown, the electrode structure 2 includes a first metal layer 232 and a second metal layer 234. The first metal layer 232 is electrically connected to the control board 6, and the second metal layer 234 is electrically connected to the deformation detection sensor 3. The second metal layer 234 is located between the first metal layer 232 and the housing 1. The first metal layer 232 is used to emit electrical energy, and the deformation detection sensor 3 is used to detect the deformation of the second metal layer 234.

[0046] In this embodiment, the first metal layer 232 and the second metal layer 234 are conductive layers. The control board 6 is electrically connected to the first metal layer 232 and can control the first metal layer 232 to generate electrical energy to treat the treatment surface. The deformation detection sensor 3 is electrically connected to the second metal layer 234. When the second metal layer 234 deforms, the deformation detection sensor 3 generates a deformation signal and sends the deformation signal to the control board 6, so that the control board 6 controls the electrode structure 2 to emit electrical energy.

[0047] Understandably, when the treatment head 100 performs treatment, the second metal layer 234 is located on the side of the first metal layer 232 facing away from the treatment surface. When the first metal layer 232 deforms due to contact between the treatment head 100 and the treatment surface, it will cause the second metal layer 234 to deform, thereby triggering the deformation detection sensor 3. The first metal layer 232 and the second metal layer 234 have a certain elastic deformation capability. Optionally, the first metal layer 232 and the second metal layer 234 are copper foils; the first metal layer 232 is provided with an electrical energy generation circuit.

[0048] In one embodiment of the present invention, such as Figure 3 and Figure 4 As shown, the electrode structure 2 also includes a first insulating layer 231, a second insulating layer 233 and a third insulating layer 235. The second insulating layer 233 is disposed between the first metal layer 232 and the second metal layer 234. The first insulating layer 231 is disposed on the side of the first metal layer 232 away from the second metal layer 234. The third insulating layer 235 is disposed on the side of the second metal layer 234 away from the first metal layer 232.

[0049] In this embodiment, the first insulating layer 231, the first metal layer 232, the second insulating layer 233, the second metal layer 234, and the third insulating layer 235 are sequentially stacked. This provides mutual insulation between the first metal layer 232 and the second metal layer 234, and also between them and the outside environment. This ensures the normal operation of the circuits within the first and second metal layers 232 and 234, prevents short circuits or interference, and improves the electrical insulation performance of the electrode mechanism. When the treatment head 100 performs treatment, the first insulating layer 231 contacts the treatment surface, transmitting deformation to the second metal layer 234. The deformation detection sensor 3, electrically connected to the second metal layer 234, is then triggered. It is understood that the deformation detection sensor 3 passes through the third insulating layer 235 and connects to the second metal layer 234.

[0050] In practical implementation, the first insulating layer 231, the second insulating layer 233, and the third insulating layer 235 can be polyimide film or polyester film, etc. The first insulating layer 231, the second insulating layer 233, and the third insulating layer 235 have good insulation properties and also have a certain mechanical protection function to increase the overall performance and reliability of electrode structure 2. The first insulating layer 231, the first metal layer 232, the second insulating layer 233, the second metal layer 234, and the third insulating layer 235 can be connected by adhesive bonding or directly integrally molded. Electrode structure 2 is an FPC structure, and no specific limitation is made here.

[0051] In one embodiment of the present invention, such as Figure 3 , Figure 4 and Figure 7As shown, the first metal layer 232 includes a plurality of radio frequency electrodes 23 spaced apart. The plurality of radio frequency electrodes 23 are spaced apart between the first insulating layer 231 and the second insulating layer 233. The deformation detection sensor 3 includes a plurality of electrodes, and the deformation detection sensor 3 is arranged in a one-to-one correspondence with the radio frequency electrodes 23.

[0052] In this embodiment, multiple radio frequency electrodes 23 are spaced apart on the first insulating layer 231 and the second insulating layer 233 to ensure the treatment area of ​​the electrode structure 2 and improve the treatment effect of the treatment head 100. A deformation detection sensor 3 is configured in a one-to-one correspondence with each radio frequency electrode 23. When any one of the multiple radio frequency electrodes 23 comes into contact with the treatment surface, the deformation detection sensor 3 can quickly and accurately detect the deformation of the electrode structure 2. The polarities of the multiple radio frequency electrodes 23 can be different to improve the treatment effect of the treatment head 100.

[0053] In practical implementation, the electrode structure 2 can be arranged in a ring shape, and multiple radio frequency electrodes 23 can be arranged in a fan-shaped interval between the first insulating layer 231 and the second insulating layer 233. Correspondingly, the connection part between the housing 1 and the electrode structure 2 can also be arranged in a ring shape, and the clearance cavity 12 is also arranged in a fan-shaped interval. The electrode structure 2 and the housing 1 enclose a through cavity that connects to the mounting cavity 15, so that the electrode structure 2 can be combined with other treatment structures such as ultrasound transducers. There can be one, two, three, four or other numbers of radio frequency electrodes 23, and the radio frequency electrodes 23 can be arranged symmetrically, without specific limitation.

[0054] In one embodiment of the present invention, such as Figure 2 , Figure 4 and Figure 7 As shown, the treatment head 100 also includes a reinforcing layer 4, which is disposed between the electrode structure 2 and the housing 1. The reinforcing layer 4 has a clearance hole 41 corresponding to the deformation detection sensor 3, and the deformation detection sensor 3 is disposed in the clearance hole 41.

[0055] In this embodiment, the reinforcing layer 4 is connected to the side of the electrode structure 2 closest to the housing 1. The reinforcing layer 4 enhances the overall mechanical strength of the electrode structure 2, preventing it from being damaged by bending or pressure during assembly and operation. It also provides support for the electrode structure 2 to facilitate subsequent installation and assembly. The deformation detection sensor 3 and the reinforcing layer 4 are located on the same side of the electrode structure 2. The reinforcing layer 4 has a clearance hole 41 corresponding to the deformation detection sensor 3 to avoid obstructing the deformation detection sensor 3. The deformation detection sensor 3 is suspended in the clearance hole 41 and directly connected to the electrode structure 2.

[0056] In practical implementation, the thickness of the reinforcing layer 4 can be selected according to requirements. When the thickness of the reinforcing layer 4 is greater than the thickness of the deformation detection sensor 3, the clearance hole 41 also serves to provide deformation space for the electrode structure 2 and displacement space for the deformation detection sensor 3. The material of the reinforcing layer 4 can be polyimide, glass fiber reinforced epoxy resin, or polyester, etc., to improve the mechanical strength and bending resistance of the electrode structure 2, giving it better elastic deformation capability.

[0057] In one embodiment of the present invention, such as Figures 2 to 5 As shown, the housing 1 has a connecting surface 11 and a notch 13 that connects the connecting surface 11 and the mounting cavity 15. The electrode structure 2 has a connecting arm 24. The electrode structure 2 is connected to the connecting surface 11. The connecting arm 24 passes through the notch 13 and is connected to the control board 6, so that the electrode structure 2 is electrically connected to the control board 6.

[0058] In this embodiment, the housing 1 has a connecting surface 11 for connecting to the electrode structure 2. The connecting surface 11 has a recessed cavity 12 for accommodating the deformation detection sensor 3. When the electrode structure 2 is connected to the housing 1, the electrode structure 2 fits against the connecting surface 11, and the deformation detection sensor 3 is suspended in the recessed cavity 12, thus providing a certain deformation space for the electrode structure 2 and a certain displacement space for the deformation detection sensor 3. The electrode structure 2 has a connecting arm 24 for electrical connection with the control board 6 to realize signal transmission between the electrode structure 2 and the control board 6. The housing 1 has a notch 13 corresponding to the connecting arm 24. When the electrode structure 2 is connected to the connecting surface 11 of the housing 1, the connecting arm 24 passes through the notch 13 of the housing 1 to facilitate electrical connection with the control board 6 in the mounting cavity 15. When the electrode structure 2 is connected to the housing 1, the electrode structure 2 can be positioned and installed through the cooperation of the connecting arm 24 and the notch 13. In actual implementation, the connecting arm 24 can be an FPC structure, and the notch 13 can be located at the periphery of the connecting surface 11. After the connecting arm 24 passes through the notch 13, it can be extended according to the connection requirements, without specific limitations.

[0059] In actual implementation, the housing 1 can be hollowed out to form a clearance cavity 12, or the housing 1 can be recessed on the connecting surface 11 to form a clearance cavity 12. The clearance cavity 12 can be set one-to-one or one-to-many with the deformation detection sensor 3, without specific limitation. Two connecting arms 24 can be provided. The two connecting arms 24 can be used for electrical connection between the first metal layer 232 and the second metal layer 234 and the control board 6, respectively. The deformation detection sensor 3 can be electrically connected to the control board 6 through the second metal layer 234 and the connecting arms 24.

[0060] In one embodiment of the present invention, such as Figure 1 and Figure 4As shown, the treatment head 100 also includes a temperature detection sensor 5, which is connected to the electrode structure 2 and is spaced apart from the deformation detection sensor 3. The temperature detection sensor 5 is used to detect the temperature of the electrode structure 2.

[0061] In this embodiment, the temperature detection sensor 5 is connected to the electrode structure 2 to detect the working temperature of the electrode structure 2 in real time, so as to prevent the radio frequency energy emitted by the electrode structure 2 from accumulating and causing the temperature to be too high and burn the user.

[0062] Optionally, the temperature sensor 5 can be disposed on the second surface 22 in a one-to-one correspondence with the radio frequency electrode 23. When the electrode structure 2 is connected to the housing 1, the temperature sensor 5 is also suspended in the clearance cavity 12 of the housing 1 to prevent the temperature sensor 5 from colliding with the housing 1 when the electrode structure 2 deforms. The deformation detection sensor 3 is disposed in a one-to-one correspondence with the radio frequency electrode 23 to detect the temperature of each radio frequency electrode 23 individually. The temperature sensor 5 can be electrically connected to the control board 6, so that the control board 6 can control the working power of the radio frequency electrode 23 according to the independent temperature of each radio frequency electrode 23. When the working temperature of any radio frequency electrode 23 is too high, the corresponding temperature sensor 5 can quickly and timely send a warning signal to the control board 6. The temperature sensor 5, the deformation detection sensor 3 and the electrode structure 2 can be bonded or welded together, which is not specifically limited here. In actual implementation, the temperature sensor 5 can be electrically connected to the control board 6 through the second metal layer 234 and the connecting arm 24.

[0063] In one embodiment of the present invention, such as Figure 1 and Figure 6 As shown, electrode structure 2 is bonded to housing 1.

[0064] In this embodiment, the electrode structure 2 and the housing 1 are connected by an adhesive layer 7, which can be 3M adhesive. In actual implementation, the electrode structure 2 is circular to facilitate a more uniform distribution of the radio frequency energy emitted by the electrode structure 2 on the treatment surface, avoiding excessive heat generation on the treatment surface and preventing damage. The adhesive layer 7 fully covers the connection surface 11 of the housing 1 to ensure the connection strength between the electrode structure 2 and the housing 1. Grooves 14 can be provided on the connection surface 11 to improve the firmness of the connection between the adhesive layer 7 and the connection surface 11. For example, when 3M adhesive is applied to the connection surface 11, some of the adhesive will fill the groove 14, thus increasing the adhesive area and allowing the adhesive to fully interlock and bond with the connection surface 11, improving the adhesion between the adhesive layer 7 and the connection surface 11 and ensuring the firmness of the bond.
