Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an ultrasonic therapy head, an ultrasonic therapy instrument, and a method for testing their fit. Background Technology

[0002] With social development and advancements in medical technology, the application of ultrasound therapy devices is becoming increasingly widespread. Ultrasound therapy devices focus ultrasound energy and precisely target the tissue for treatment.

[0003] Because ultrasound focuses high energy, the treatment area needs to be in close contact with the surface of the device during ultrasound therapy. Existing ultrasound therapy devices generally use contact sensors to detect whether the device is in contact with the treatment area, such as pressure sensors or capacitive contact sensors. However, due to limitations in the sensitivity and accuracy of these sensors, they cannot accurately determine whether the ultrasound therapy device is making good contact with the treatment area, leading to poor contact during treatment. This can result in the inability to achieve the desired therapeutic effect and may even cause skin burns. Summary of the Invention

[0004] The main objective of this invention is to provide an ultrasonic treatment head that addresses the problem of not being able to determine whether the treatment device fits the treatment area well during ultrasonic treatment.

[0005] To achieve the above objectives, the present invention proposes an ultrasonic treatment head, comprising: a housing assembly having a mounting cavity and a treatment window communicating with the mounting cavity; an ultrasonic transducer disposed within the mounting cavity; a contact detection assembly including an elastic element and an image acquisition unit, one end of the elastic element being disposed at the outer edge of the treatment window and the other end being used to contact the surface of the treatment area, the image acquisition unit being disposed on one side of the elastic element and used to acquire images of the elastic deformation of the elastic element; and a control unit, the control unit being communicatively connected to the image acquisition unit and the ultrasonic transducer, and controlling the operating mode of the ultrasonic transducer according to the detection signal of the image acquisition unit.

[0006] In one embodiment of the present invention, the outer edge of the treatment window is provided with a groove, one end of the elastic member is disposed in the groove, and the height of the elastic member is not less than the depth of the groove.

[0007] In one embodiment of the present invention, both the groove and the fitting detection component are provided with a plurality of grooves, the plurality of grooves are arranged circumferentially at intervals on the outer edge of the treatment window, and each elastic element is provided in each groove.

[0008] In one embodiment of the present invention, the opening shape of the treatment window is circular;

[0009] And / or, the opening shape of the groove is circular.

[0010] In one embodiment of the present invention, a cavity is formed by recessing one sidewall of the groove in a direction away from the treatment window, the depth of the cavity being the same as the depth of the groove, and the image acquisition unit is disposed in the cavity.

[0011] In one embodiment of the present invention, the housing assembly includes an outer shell and an inner shell, the outer shell being fitted around the outer periphery of the inner shell, one end of the inner shell forming the treatment window, and the interior of the inner shell forming the mounting cavity.

[0012] In one embodiment of the present invention, the inner shell bends and extends along the inner edge of the treatment window to form a first platform, and the outer shell bends and extends toward the center of the treatment window to form a second platform. The first platform and the second platform are located on the same horizontal plane, and the groove is formed on the second platform.

[0013] In one embodiment of the present invention, a gap is formed between the second platform and the outer surface of the inner shell, the groove communicates with the gap, and one end of the elastic member abuts against the outer surface of the inner shell;

[0014] And / or, the elastic element is made of silicone.

[0015] The present invention also proposes an ultrasonic therapy device, comprising any of the ultrasonic therapy heads, a main unit, and a handle described above, wherein the ultrasonic therapy head is mounted on the handle and is communicatively connected to the main unit.

[0016] This invention also proposes a method for detecting the fit of an ultrasound therapy device as described above. The main unit is equipped with a fit detection model, which can process and determine the degree of contact between the elastic element and the treatment area. The fit detection method includes the following steps:

[0017] The control and detection unit collects deformation data of the elastic component;

[0018] Receive the deformation data and compare it with a preset model based on the fit detection model;

[0019] If the deformation data matches the preset model, it is determined that the ultrasonic treatment head fits well with the skin, and the ultrasonic treatment device is turned on.

[0020] The ultrasonic therapy head proposed in this invention includes a housing assembly, a contact detection assembly, a control unit, and an ultrasonic transducer. When the therapy head is in contact with the treatment area, the contact detection assembly acquires an image of the deformed elastic material via an image acquisition unit and transmits the image to the contact detection model to determine the degree of contact between the elastic material and the treatment area, i.e., the fit between the treatment window and the treatment area. Based on the determination result, the control unit controls the ultrasonic transducer to operate, and the ultrasonic waves emitted by the transducer act on the treatment area to achieve the purpose of ultrasonic therapy. The ultrasonic therapy head proposed in this invention can determine whether the treatment window and the treatment area are well-fitted during ultrasonic therapy, thereby achieving the expected therapeutic effect.

[0033] This invention proposes an ultrasonic treatment head.

[0034] Combination Figure 1 and Figure 2 As shown, the ultrasonic treatment head includes: a housing assembly 10, which has a mounting cavity and a treatment window 122a communicating with the mounting cavity; an ultrasonic transducer 40, which is disposed in the mounting cavity; a contact detection assembly 20, which includes an elastic element 22 and an image acquisition unit 21, one end of the elastic element 22 being disposed at the outer edge of the treatment window 122a and the other end being used to contact the surface of the treatment area, the image acquisition unit 21 being disposed on one side of the elastic element 22 and used to acquire images of the elastic deformation of the elastic element 22; and a control unit, which is communicatively connected to the image acquisition unit 21 and the ultrasonic transducer 40, and controls the working mode of the ultrasonic transducer 40 according to the detection signal of the image acquisition unit 21.

[0035] In this embodiment, the housing assembly 10 includes an outer shell 11 and an inner shell 12. The outer shell 11 is fitted around the outer periphery of the inner shell 12. The inner shell 12 has a mounting cavity inside. The bottom end face of the inner shell 12 communicates with the mounting cavity and forms a treatment window 122a. During ultrasound treatment, ultrasound waves pass through the treatment window 122a and act on the surface of the treatment area. The outer shell 11 and the inner shell 12 are a through structure from one end of the treatment window 122a to the end opposite to the treatment window 122a. The end of the inner shell 12 opposite to the treatment window 122a is sealed by a sealing gasket and connected to the shell cover. The outer shell 11 and the inner shell 12 have the same shape, such as circular or square. The outer shell 11 further strengthens the overall structural strength of the housing assembly 10 based on the inner shell 12. In other embodiments, the housing assembly 10 is a spherical shell structure with a mounting cavity inside, and a treatment window 122a communicating with the mounting cavity at one end.

[0036] An ultrasonic transducer 40 is fixedly installed within the mounting cavity. The ultrasonic transducer 40 is a device that emits ultrasonic waves. It is positioned facing the treatment window 122a, allowing the ultrasonic waves to pass through and focus on the treatment area. An acoustic membrane 30 is attached to the treatment window 122a, which allows ultrasonic waves to pass through. During ultrasonic treatment, the ultrasonic treatment head is typically immersed in water. The acoustic membrane 30 seals the treatment window 122a, preventing water from entering the treatment head and damaging the instrument, thus providing good waterproof performance. Simultaneously, the acoustic membrane 30 has a similar refractive index to water, reducing energy loss during ultrasonic wave transmission between the membrane and water. One end of the ultrasonic transducer 40, emitting ultrasonic waves, faces the acoustic membrane, allowing the focused ultrasonic energy to pass through the treatment window 122a and irradiate the treatment area, increasing the energy density and treatment efficiency. The other end of the ultrasonic transducer 40 is fixedly connected to the inner wall of the inner shell 12.

[0037] The fit detection component 20 includes an elastic element 22 and an image acquisition unit 21. The elastic element 22 undergoes elastic deformation under pressure and returns to its original shape after stress release. The elastic element 22 can be disposed on the end face of the outer edge of the treatment window 122a, with one end connected to the end face of the outer edge of the treatment window 122a and the other end protruding from the end face and contacting the surface of the treatment area. Alternatively, the elastic element 22 can be disposed within a groove 112a on the outer edge of the treatment window 122a, with one end connected to the bottom of the groove 112a and the other end contacting the surface of the treatment area. When the treatment window 122a contacts the surface of the treatment area, the treatment area also contacts and compresses the elastic element 22. The image acquisition unit 21 is disposed on one side of the elastic element 22. The image acquisition unit 21 can be a CCD camera, infrared camera, etc., and can acquire and record images or contours of the target object. When the elastic element 22 undergoes elastic deformation, the images and contours before and after the deformation can be accurately recorded.

[0038] The control unit controls the operation of the ultrasonic treatment head. The control unit is communicatively connected to the fit detection assembly 20 and the ultrasonic transducer 40. The fit detection assembly 20 transmits the acquired image of the deformed elastic element 22 back to the control unit, which then transmits it to the fit detection model to determine the degree of contact between the elastic element 22 and the treatment area. When the determination result indicates good fit between the elastic element 22 and the treatment area, the control unit controls the ultrasonic treatment head to start operating. When poor fit occurs, the control unit keeps the ultrasonic treatment head in the off state and alerts the user to the poor fit.

[0039] The ultrasonic treatment head proposed in this invention includes a housing assembly 10, a contact detection assembly 20, and a control unit. It has the function of detecting the contact status between the treatment head and the treatment area. When the ultrasonic treatment head contacts the surface of the treatment area, the elastic element 22 in the contact detection assembly 20 is compressed and deformed. The image acquisition unit 21 in the contact detection assembly 20 acquires an image of the deformed elastic element 22 and transmits the deformed image to the contact detection model to determine the contact status between the treatment window 122a and the treatment area. After confirming good contact between the ultrasonic treatment head and the surface of the treatment area, the ultrasonic treatment head is activated to focus ultrasonic energy on the treatment area, achieving precise treatment.

[0040] Combination Figure 2 and Figure 3 As shown, in one embodiment of the present invention, the outer edge of the treatment window 122a is provided with a groove 112a, one end of the elastic member 22 is provided in the groove 112a, and the height of the elastic member 22 is not less than the depth of the groove 112a.

[0041] Optionally, in this embodiment, the elastic element 22 is embedded in the groove 112a on the outer edge of the treatment window 122a. The groove 112a can fix and limit the elastic element 22, making the connection between the elastic element 22 and the groove 112a more stable. At the same time, when the elastic element 22 is squeezed, the groove 112a guides the elastic element 22, improving the accuracy of the deformation acquisition of the elastic element 22 by the fit detection component 20. The height of the elastic element 22 when it is not under force can be set to be no less than the depth of the groove 112a. One end of the elastic element 22 is connected to the bottom of the groove 112a, and the other end is flush with or slightly protruding from the outer edge of the treatment window 122a. While meeting the height requirements of the elastic element 22, this improves the sensitivity of the deformation of the elastic element 22 after the treatment head contacts the treatment area, and avoids the elastic element 22 protruding outward from the treatment window 122a, which may excessively obstruct the surface contact between the treatment window 122a and the treatment area, thereby improving the focusing accuracy of the ultrasound at the preset position. In other embodiments, the height of the elastic member 22 is lower than the depth of the groove 112a, corresponding to a special treatment area structure, such as in a treatment area where the bone is more prominent, the surface of the treatment area will have a protrusion. When the height of the elastic member is lower than the depth of the groove 112a, the elastic member will also have a more obvious deformation when it comes into contact with the surface of the protruding area.

[0042] Combination Figure 2 and Figure 4 As shown, optionally, in one embodiment of the present invention, both the groove 112a and the fitting detection component 20 are provided with a plurality of grooves 112a, and the plurality of grooves 112a are arranged circumferentially at intervals on the outer edge of the treatment window 122a, and each elastic member 22 is provided in each groove 112a.

[0043] In this embodiment, the number of grooves 112a and the number of adhesion detection components 20 are the same, and there are multiple grooves 112a and adhesion detection components 20 are distributed at intervals on the outer periphery of the treatment window 122a. Each groove 112a is provided with an elastic element 22. The cooperation method of the elastic element 22, the image acquisition unit 21, and the groove 112a is the same as in the above embodiment. Setting multiple sets of grooves 112a and adhesion detection components 20 on the outer periphery of the treatment window 122a can detect the surface adhesion status of the treatment head at different positions with the treatment area, prevent misjudgment when the treatment window 122a is tilted, and further improve the accuracy of adhesion detection between the treatment window 122a and the treatment area.

[0044] In practical applications, based on the scheme of providing multiple grooves 112a and the bonding detection component 20 mentioned in the above embodiments, the present invention also provides an embodiment. (Refer to...) Figure 3As shown, in this embodiment, there are three grooves 112a and three fitting detection components 20. The three grooves 112a are evenly spaced around the outer periphery of the treatment window 122a. Each groove 112a contains an elastic element 20, and each elastic element 20 has an image detection unit 21 on one side. The three grooves 112a and the fitting detection components 20 can detect the fitting of the treatment head to the treatment area at different positions, while avoiding the increase in processing costs caused by too many grooves.

[0045] Please continue to refer to Figure 4 In one embodiment of the present invention, the opening shape of the treatment window 122a is circular;

[0046] And / or, the opening shape of the groove 112a is circular.

[0047] Optionally, the opening shape of the treatment window 122a can be circular, square, or rhomboid. In this embodiment, the opening shape of the treatment window 122a is circular.

[0048] While the opening shape of the treatment window 122a may or may not be limited to a circle, the opening shape of the groove 112a can be circular, rectangular, or other shapes. In this embodiment, the opening shape of the groove 112a is circular. The circular groove 112a has no sharp edges, which avoids uneven force on the elastic element 22 at the corners and further improves the accuracy of the deformation change of the elastic element 22 after the treatment head contacts the treatment area.

[0049] Combination Figure 2 and Figure 3 As shown, optionally, in one embodiment of the present invention, a cavity 113a is formed by recessing one sidewall of the groove 112a in a direction away from the treatment window 122a. The depth of the cavity 113a is the same as the depth of the groove 112a, and the image acquisition unit is disposed in the cavity 113a.

[0050] In this embodiment, a cavity 113a is recessed into one sidewall of the groove 112a. The cavity 113a is located on the side of the groove 112a away from the treatment window 122a. The shape of the cavity 113a can be a cuboid, a cylinder, etc. The depth of the cavity 113a is the same as the depth of the groove 112a, which allows the image acquisition unit 21 to have sufficient acquisition space to acquire the overall shape of the elastic member 22 after deformation, further improving the accuracy of image acquisition by the fit detection component.

[0051] The image acquisition unit 21 is fixedly mounted on the inner wall of the cavity 113a. The image acquisition unit 21 can be located at any position above, below, or in the cavity 113a. In this embodiment, the image acquisition unit 21 is located in the middle of the cavity 113a. The image acquisition unit 21 located in the middle of the cavity 113a further enhances the image acquisition capability of capturing images of the overall shape of the elastic member 22 before and after deformation. A gap exists between the image acquisition unit 21 and the elastic member 22, which increases the visible range of the image acquisition unit 21 and further improves its ability to capture images of the overall shape of the elastic member 22.

[0052] Please continue to refer to Figure 1 and Figure 2 Optionally, in one embodiment of the present invention, the inner shell 12 bends and extends along the inner edge of the treatment window 122a to form a first platform 121, and the outer shell 11 bends and extends toward the center of the treatment window 122a at one end to form a second platform 111. The first platform 121 and the second platform 111 are located on the same horizontal plane, and the groove 112a is formed on the second platform 111.

[0053] In this embodiment, the inner shell 12 extends a first platform 121 towards the center of the treatment window 122a. The first platform 121 is surrounded on all four sides with an opening in the center, through which ultrasound waves pass. A sound-transmitting membrane 30 is attached to the first platform 121. The first platform 121 increases the contact area of ​​the sound-transmitting membrane 30, resulting in a tighter fit. The outer shell 11 extends a second platform 111 in the same direction as the first platform 121, and is located on the same horizontal plane as the first platform 121. The first platform 121 and the second platform 111 abut against each other, and a groove 112a is formed on the second platform 111. The second platform 111 allows for a larger groove 112a, resulting in a larger contact area between the elastic element 22 and the treatment area, further improving the accuracy of fit detection.

[0054] Combination Figure 2 and Figure 3 As shown, in one embodiment of the present invention, a gap is formed between the second platform 111 and the outer surface of the inner shell 12, the groove 112a communicates with the gap, and one end of the elastic member 22 abuts against the outer surface of the inner shell 12.

[0055] And / or, the elastic element 22 is made of silicone.

[0056] In this embodiment, the outer shell 11 and the inner shell 12 are connected by a snap-fit ​​connection. A groove 112a is provided on the second platform 111. There is no snap-fit ​​structure at the location of the groove 112a. A gap is left between the second platform 111 and the outer surface of the inner shell 12 at the groove 112a. The groove 112a penetrates the second platform 111 and communicates with the gap. The gap between the second platform 111 and the outer surface of the inner shell 12 can increase the depth of the groove 112a without increasing the thickness of the outer shell 11, thus making the height of the elastic element 22 higher. With the increased height of the elastic element 22, the deformation under the same pressure also increases. Therefore, when the treatment head contacts the treatment area, the deformation change of the elastic element 22 captured by the image acquisition unit 21 is more obvious, further improving the accuracy of the fit detection.

[0057] In addition, the gap between the second platform 111 and the outer surface of the inner shell 12 can also serve as a communication transmission channel between the image acquisition unit 21, the control unit and the ultrasonic transducer. The signal lines can be arranged in the gap, saving the structural space of the shell assembly 10 and making the shell assembly 10 more aesthetically pleasing.

[0058] When a gap is formed between the second platform 111 and the outer surface of the inner shell 12, whether or not a gap is defined, the elastic element 22 can be an elastic material such as silicone or rubber. In this embodiment, the elastic element 22 is made of silicone. Silicone has excellent elasticity; when the ultrasonic treatment head comes into contact with the surface of the treatment area, the silicone is compressed and deformed. When the ultrasonic treatment head separates from the surface of the treatment area, the silicone returns to its original shape. In other embodiments, the elastic element 22 can also be a spring or a sheet spring.

[0059] The present invention also proposes an ultrasonic therapy device (not shown). The ultrasonic therapy device includes: an ultrasonic therapy head as described in any of the above embodiments, a main unit and a handle, wherein the ultrasonic therapy head, the main unit and the handle are all communicatively connected.

[0060] In this embodiment, one end of the handle is connected to the ultrasonic treatment head, and the other end is connected to the main unit. The main unit is connected to the handle via a cable, and the housing assembly 10 of the ultrasonic treatment head can be connected to the handle via snap-fit, threaded connection, or other means. The main unit, handle, and ultrasonic treatment head are all communicatively connected. Since the ultrasonic transducer 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, and will not be described in detail here.

[0061] This invention also proposes a method for detecting the contact between an ultrasonic therapy device and the treatment area. The ultrasonic therapy device described in the above embodiment includes a contact detection model within the main unit. This model can process and determine the degree of contact between the elastic element 22 and the treatment area. The contact detection method includes the following steps:

[0062] Step S1: Control the detection unit to collect deformation data of the elastic element;

[0063] Step S2: Receive the deformation data and compare it with a preset model based on the fitting detection model;

[0064] Step S3: If the deformation data matches the preset model, it is determined that the ultrasonic treatment head fits well with the skin, and the ultrasonic treatment device is turned on.

[0065] In this embodiment, the fitting detection model can be selected from some classic deep learning models, such as convolutional neural networks (CNN), to facilitate operation and improve the efficiency of model building.

[0066] When building the model, a certain amount of sample data needs to be collected. The sample data includes image data of the elastic element 22 in contact with the skin, as well as information such as the actual contact between the corresponding treatment window 122a and the treatment area, and the pressure level of the elastic element 22. The image sample data can be preprocessed, including image denoising, scaling, and cropping, to improve the accuracy of subsequent deep learning algorithm processing.

[0067] Then, the preprocessed image sample data is input into the fit detection model for deep learning training. During training, the model needs to be continuously optimized by combining image data and fit degree to accurately classify and judge images, thereby obtaining the deformation images of elastic element 22 and the corresponding pressure levels for different fit degrees. After the deep learning model is trained, it needs to be tested using image samples with multiple fit degrees to verify the model's accuracy and robustness.

[0068] In step S1, after the treatment window 122a contacts the treatment area, the detection unit can be activated to collect deformation data of the elastic element. This deformation data can be a deformation image of the elastic element 22, the pressure value experienced by the elastic element 22, the contact area between the elastic element 22 and the treatment area, or any combination of the above three. In step S2, the deformation data collected by the detection unit can be input into the fit detection model. The fit detection model processes the data and compares it with a preset model for judgment. This preset model is a model derived from deep learning and has good accuracy. In step S3, when the deformation data matches the preset model, the judgment result is good fit. At this point, the ultrasonic transducer 40 is then activated to improve its working performance.

[0069] The fitting detection model's judgment process includes judging the shape of the elastic element 22, judging the pressure level of the elastic element 22, and judging the contact area between the elastic element 22 and the treatment area.

[0070] The shape judgment process of elastic element 22: The image acquisition unit 21 performs image noise reduction, scaling, and cropping preprocessing on the acquired image of the deformed elastic element 22. The processed image is input into the fit detection model, and the image data is processed to calculate the deformation of elastic element 22. The fit detection model, based on pre-learning training, obtains the corresponding deformation threshold when elastic element 22 fits well with the treatment area, and compares the actual deformation of elastic element 22 during treatment with the set threshold. If it is within this threshold range, the shape judgment of elastic element 22 is judged to meet the requirements, and the pressure level judgment of elastic element 22 begins. If it exceeds the threshold, the subsequent judgment stops, and a signal of poor fit is sent back to the control unit.

[0071] The pressure level judgment process of elastic element 22: During the initial learning and training process, the fit detection model derives a pressure threshold for good fit. During actual treatment, when the therapeutic instrument contacts the treatment area, the shape of elastic element 22 changes. The fit detection model calculates the pressure value received by elastic element 22 based on this shape change and compares it with the pre-set pressure threshold. If the pressure value received by the elastic element is within this threshold range, the shape of elastic element 22 is considered to meet the requirements. If it exceeds the threshold, subsequent judgment stops, and a signal indicating poor fit is sent back to the control unit. Since the pressure threshold is related to the material and cross-sectional area of ​​elastic element 22, it needs to be defined based on the actual fit condition and is not further limited here. Compared with the traditional method of setting pressure sensors, this invention uses an image acquisition unit 21 to acquire images of the deformation of elastic element 22 and a model to calculate the deformation of elastic element 22 before obtaining the corresponding pressure value. This judgment process is not limited by the sensitivity and accuracy of the sensor, thereby improving the accuracy of judging the contact between the ultrasonic therapeutic instrument and the treatment area.

[0072] The process for determining the contact area between the elastic element 22 and the treatment area: After pressure assessment, the fit detection model calculates the contact area between the elastic element 22 and the treatment area based on the pressure value of the elastic element 22. This area is then combined with the image data of the elastic element 22 to determine whether the elastic element 22 fits well with the treatment area. Through learning and training, the fit detection model generates the deformation of the elastic element 22 corresponding to different contact areas with the treatment area. This judgment process reduces the probability of misjudgment due to tilting of the treatment head against the treatment area.

[0073] When all the requirements of the judgment process are met, the deep learning model for fit detection issues a command indicating that the elastic element 22 is in good contact with the skin, and transmits it to the control unit. The control unit then activates the ultrasonic transducer 40 to begin ultrasonic treatment. In practical applications, the deep learning model for fit detection will be continuously trained and optimized based on the fit between the treatment window 122a and the treatment area to further improve the accuracy of fit detection judgment.
