Ultrasonic wave emitted by ultrasonic transducer passes through liquid acoustic medium and acoustic membrane arranged at the acoustic window of therapeutic instrument in turn, and focuses ultrasonic wave on target area to achieve the purpose of ultrasonic therapy. However, due to the limitation of assembly process, there will inevitably be bubbles in liquid acoustic medium. During ultrasonic therapy, if the orientation of therapeutic instrument is improper, bubbles may move towards acoustic window.

[0027] The present application provides an ultrasonic treatment head.

[0028] In combination Figures 1 to 4 As shown in the figure, in an embodiment of the present application, the ultrasonic treatment head comprises a main body assembly 10, a sound-transmitting film 20, a detection module 30 and a control unit; the main body assembly 10 comprises a shell 11 and a transducer 12 arranged in the shell 11, the shell 11 forms a mounting cavity 111 with a sound-transmitting window 112, and the mounting cavity 111 is filled with a sound-transmitting medium; the sound-transmitting film 20 blocks the sound-transmitting window 112; the detection module 30 is installed on the shell 11 and is used to detect whether the main body assembly 10 is in a first posture or whether there is a bubble at the sound-transmitting film 20; the control unit is in communication connection with the detection module 30 and the transducer 12, and the control unit is used to control the opening or closing of the transducer 12; wherein when the main body assembly 10 is in the first posture, the bubbles in the sound-transmitting medium float to the sound-transmitting film 20; when the main body assembly 10 is in the first posture or there is a bubble at the sound-transmitting film 20, the control unit controls the closing of the transducer 12.

[0029] In the present embodiment, the sound-transmissive medium is generally water, which has good acoustic properties and can effectively transmit ultrasonic waves with less absorption and scattering of sound waves. The sound-transmissive film 20 is made of polyurethane, polyvinyl chloride or other materials, and has the functions of blocking the sound-transmissive window 112 of the ultrasonic treatment head and having good sound-transmission and waterproof properties to prevent external liquid (such as liquid in the patient's body or water) from entering the inside of the device and prevent the sound-transmissive medium from flowing out of the ultrasonic treatment head.

[0030] The detection module 30 is installed on the housing 11 and is used to detect whether the main body assembly 10 is in the first attitude or whether there is a bubble near the sound-transmissive film 20. When the ultrasonic treatment head is moved, swung or rotated by the user during ultrasonic treatment, the attitude of the ultrasonic treatment head changes. The present application defines the first attitude as the state when the ultrasonic treatment head is rotated to the side of the sound-transmissive window 112 facing upward, i.e., the state when the ultrasonic treatment head is inverted. When the ultrasonic treatment head is in the first attitude, the bubble moves to the sound-transmissive film 20 under the action of buoyancy. Therefore, the detection of whether the main body assembly 10 is in the first attitude by the detection module 30 can also reflect whether there is a bubble near the sound-transmissive film 20.

[0031] The control unit is in communication connection with the detection module 30 and the transducer 12. The control unit is responsible for receiving the detection signal of the detection module 30 and controlling the opening and closing of the transducer 12 accordingly to ensure the safe and effective operation of the ultrasonic treatment head. The control unit can take various forms, including but not limited to a microprocessor, a microcontroller, a digital signal processor (DSP) or a dedicated integrated circuit (ASIC).

[0032] When the detection module 30 (such as a gyroscope sensor 31, a distance sensor 32, an image sensor, etc.) detects the corresponding physical quantity (such as position, distance, image, etc.), it is converted into an electrical signal. The electrical signal is preprocessed through amplification, filtering, analog-to-digital conversion (ADC) and other steps. The processed signal is transmitted to the control unit through wired or wireless means. After receiving the signal, the control unit analyzes and makes decisions according to the preset logic or algorithm. According to the decision result, the control unit controls the transducer 12 to remain open or closed through the corresponding output interface (such as GPIO, PWM, etc.).

[0033] The present application sets the detection module 30 to detect or judge whether there is a bubble near the sound-transmissive film 20. When there may be a bubble near the sound-transmissive film 20, the control unit controls the transducer 12 to be closed to prevent the ultrasonic waves emitted by the transducer 12 from being focused on the surface of the sound-transmissive film 20 by the bubble, thereby preventing the problem of the sound-transmissive film 20 being broken, and improving the safety and convenience of the ultrasonic treatment head.

[0034] In combination withFigure 2 As shown in the embodiment of the utility model, the detection module 30 includes a gyroscope sensor 31, which is installed on the shell 11 and used to collect position information of the main body assembly 10 to confirm whether the main body assembly 10 is in the first posture.

[0035] In this embodiment, the gyroscope can provide high-precision angle measurement and can monitor the posture change of the device in real time, providing a continuous data stream to enable the control unit to react quickly. The gyroscope has high sensitivity to slight changes in posture, which can improve the accuracy of detection.

[0036] To further improve the accuracy of detection, the gyroscope sensor 31 is manufactured using high-precision MEMS technology, with high sensitivity and low noise characteristics. In actual use, the gyroscope sensor 31 can monitor the spatial posture of the main body assembly 10 in real time, and once it detects that the main body assembly 10 is in the first posture that may cause the bubble to float to the sound-transparent membrane 20, it immediately sends a signal through the control unit to turn off the transducer 12, avoiding potential damage to the sound-transparent membrane 20 by the bubble. In other embodiments, the position information of the main body assembly 10 can also be detected by an acceleration sensor.

[0037] In combination Figure 2 As shown in the embodiment of the utility model, the gyroscope sensor 31 is a three-axis gyroscope, and the axis of the shell 11 coincides with one of the detection axes of the three-axis gyroscope.

[0038] In this embodiment, the three-axis gyroscope can detect the rotational motion of the device in three orthogonal axes, more accurately determine the posture and motion of the main body assembly 10, and accurately detect the position information of the main body assembly 10 in space. The axis of the shell 11 coincides with one of the detection axes of the three-axis gyroscope, which can reduce errors caused by non-coincidence of the axes to ensure the accuracy of detection.

[0039] In combination Figure 2 As shown in the embodiment of the utility model, the end of the shell 11 away from the sound-transparent window 112 is provided with a mounting groove 113, and the gyroscope sensor 31 is installed in the mounting groove 113.

[0040] In this embodiment, the gyro sensor 31 is disposed outside the housing 11 to facilitate assembly and disassembly of the gyro sensor 31. This also reduces the impact of the acoustically transparent medium on the life of the gyro sensor 31 compared to a solution in which the gyro sensor 31 is installed within the mounting cavity 111. Because an adapter extends from the end of the ultrasonic treatment head facing away from the acoustically transparent window 112, the adapter is used to drive and connect the driver and the transducer 12. Therefore, a mounting groove 113 is provided at the end of the housing 11 facing away from the acoustically transparent window 112. The gyro sensor 31 is mounted within the mounting groove 113 to prevent interference between the gyro sensor 31 and the adapter. The design of the mounting groove 113 also allows the gyro sensor 31 to be stably fixed within the housing 11, facilitating subsequent maintenance and replacement.

[0041] The output of the gyro sensor 31 is connected to the control unit via a wire, and the wire is led out through a sealed wire hole to ensure the reliability and waterproof performance of the electrical connection.

[0042] Combine Figure 3 As shown, in one embodiment of the present invention, the detection module 30 includes a suspension member 33 and a distance sensor 32. The suspension member 33 is movably arranged in the installation cavity 111 and has a density less than that of the sound-transmitting medium. The distance sensor 32 is installed in the shell 11 and is located on the cavity wall of the installation cavity 111 away from the sound-transmitting window 112. The distance sensor 32 is used to detect the distance between itself and the suspension member 33. When the main assembly 10 is in the first posture, the distance between the suspension member 33 and the distance sensor 32 is the largest.

[0043] In this embodiment, the suspended member 33 disposed within the mounting cavity 111 is freely suspended in the acoustically transparent medium. The density of the suspended member 33 is lower than that of the acoustically transparent medium, enabling the suspended member 33 to float near the acoustically transparent membrane 20 under the action of buoyancy when the ultrasonic therapy head is in the first position, i.e., when the ultrasonic therapy head is inverted. When the ultrasonic therapy head is rotated so that the acoustically transparent window 112 faces downward, the suspended member 33 floats close to the distance sensor 32 under the action of buoyancy. The distance sensor 32 thus detects the distance to the suspended member 33, confirming whether the main assembly 10 is in the first position and providing a signal to the control unit to shut down the transducer 12.

[0044] To ensure stable floating within the acoustically transparent medium, the suspending element 33 is made of lightweight plastic and coated with a hydrophobic material to reduce friction with the acoustically transparent medium. The distance sensor 32 can be either an ultrasonic or optical distance sensor. The appropriate sensor type should be selected based on the application.

[0045] Combine Figure 3As shown in the embodiment of the utility model, the main body assembly 10 further comprises a guide pipe 34, the guide pipe 34 is arranged in the installation cavity 111 and extends along the axial direction of the shell 11, the floating piece 33 is movably arranged in the guide pipe 34, and the distance sensor 32 is located at one end of the guide pipe 34.

[0046] In the embodiment, the guide pipe 34 is arranged to guide the floating piece 33 to move in the guide pipe 34, control the moving path and moving direction of the floating piece 33, and thus improve the accuracy of the distance sensor 32 in judging whether the main body assembly 10 is in the first posture.

[0047] The inner diameter of the guide pipe 34 is greater than the maximum size of the floating piece 33, so that the floating piece 33 can move freely in the guide pipe 34. The guide pipe 34 extends along the axial direction of the shell 11 and avoids the arrangement of corners, so as to further improve the stability of the floating piece 33 moving in the guide pipe 34.

[0048] In combination Figure 4 As shown in the embodiment of the utility model, the detection module 30 is an ultrasonic detector 35, the ultrasonic detector 35 is installed on the shell 11 and located at one end of the shell 11 provided with a sound transmission window 112, and the ultrasonic detector 35 judges whether there is a bubble at the sound transmission film 20 according to the attenuation degree of the transmitted and received ultrasonic waves.

The ultrasonic detector 35 is made of high-sensitivity piezoelectric material and can accurately detect the attenuation change of ultrasonic waves. In addition, the ultrasonic detector 35 can also adopt a multi-probe design to improve the detection range and accuracy.

[0050] In combination Figure 4 As shown in the embodiment of the utility model, the shell 11 is provided with a detection groove 114 around the sound transmission window 112, and the ultrasonic detector 35 is annular and embedded in the detection groove 114.

[0051] In the embodiment, the ultrasonic detector 35 is arranged around the outer periphery of the sound transmission window 112, so that the ultrasonic detector 35 can realize 360-degree ultrasonic detection above the sound transmission film 20, further improving the detection range and accuracy. The ultrasonic detector 35 is embedded in the detection groove 114, and the detection groove 114 plays a limiting and protecting role on the ultrasonic detector 35. The ultrasonic detector 35 is flush with or lower than the end face of the shell 11, so as to ensure that the ultrasonic treatment head can be closely attached to the skin during treatment. The ultrasonic detector 35 can be installed in the detection groove 114 by means of gluing, clamping or threaded connection.

[0052] In an embodiment of the utility model, the detection module 30 is an image sensor, the image sensor is arranged in the mounting cavity 111 and located at one end of the shell 11 close to the sound transmission window 112, the image sensor collects the image at the sound transmission film 20 to judge whether there is bubble at the sound transmission film 20.

[0053] In the embodiment, the image sensor adopts a high-resolution CMOS or CCD sensor, which can clearly capture the image at the sound transmission film 20 to judge whether there is bubble at the sound transmission film 20. In order to improve the definition and accuracy of the image, the image sensor includes a miniature lens, and the focal length and aperture of the lens can be adjusted according to actual application requirements.
