Description

Technical Field

[0001] The invention relates to the technical field of ultrasonic handle testing, and in particular to an ultrasonic handle action depth calibration device and a rapid calibration method thereof. Background Art

[0002] Ultrasonic handles, such as ultrasonic transducers used in medical cosmetic or therapeutic equipment, are devices that transmit mechanical energy by generating high-frequency vibrations, converting this energy into heat or other forms of energy, and acting on the skin or specific tissue layers in the body. The different frequency and power settings of the ultrasonic handle will affect the propagation characteristics of the ultrasonic energy. By adjusting the parameters of the device (such as frequency, energy, pulse duration, etc.), it is ensured that the ultrasound can accurately reach the target action depth while avoiding unnecessary damage to the skin. Therefore, during the research and development and production process, depth calibration testing of the ultrasonic handle is an important step to ensure that the device can accurately and safely achieve the expected treatment effect. Depth calibration involves determining the penetration depth of ultrasonic energy under different settings to ensure that the energy can accurately act on the target tissue layer during treatment while avoiding unnecessary damage to surrounding non-target tissues.

[0003] In order to accurately measure the depth of action of ultrasound, the prior art uses thermochromic gel as the action object of the ultrasonic handle for detection. The specific process is as follows: the tester clamps the ultrasonic handle with a clamp, immerses the ultrasonic handle in the medium water and focuses the ultrasonic handle on the thermochromic gel, then starts the ultrasonic handle to generate ultrasonic energy, and the ultrasonic energy is transmitted to the thermochromic gel through the medium water, causing the thermochromic gel to heat up and change color, and the maximum depth of the thermochromic gel is used to calibrate the depth of action of the ultrasonic handle. However, the effect of ultrasonic energy is related to both the energy size and penetration. The prior art uses the maximum action depth as the action depth of the ultrasonic handle, which cannot reflect the energy size, but the effect of the ultrasonic energy size on the thermochromic gel is inconvenient to observe, which reduces the calibration accuracy of the action depth of the ultrasonic handle. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide an ultrasonic handle action depth calibration device and a rapid calibration method thereof which can reflect the ultrasonic action energy size in the process of calibrating the ultrasonic handle action depth by using test gel.

[0005] Provided is a device for calibrating the action depth of an ultrasonic handle, comprising a mounting frame and an observation slot for mounting the ultrasonic handle, wherein test gel and medium water are placed in the observation slot from bottom to top, and when the ultrasonic handle is mounted on the mounting frame, the ultrasonic emission direction of the ultrasonic handle is toward the test gel, the mounting frame comprises a connecting bracket for clamping the ultrasonic handle and an adjusting member for adjusting the horizontal height of the connecting bracket, and further comprises a ruler and a positioning line arranged beside the adjusting member, wherein the positioning line is used to mark the height of the connecting bracket relative to the bottom of the mounting frame, and the height change value relative to the positioning line marked by the ruler after the connecting bracket is adjusted by the adjusting member is calibrated as the action depth of the ultrasonic handle.

[0006] Furthermore, the adjusting member is a platform adjusting knob, and the platform adjusting knob is rotated to make the connecting bracket rise or fall relative to the scale, thereby driving the ultrasonic handle to approach or move away from the test gel.

[0007] Furthermore, the ruler is a ruler with scale lines.

[0008] Furthermore, the observation tank is specifically a transparent water tank with at least the front side being transparent.

[0009] Furthermore, the test gel is a thermochromic gel.

[0010] Furthermore, the mounting frame is specifically a Z-axis dovetail groove platform, and the connecting bracket serves as a slider of the Z-axis dovetail groove platform and is restricted to move in two directions of the X-axis and the Y-axis.

[0011] Furthermore, the ultrasonic handle is installed on the mounting frame in a horizontal or vertical manner.

[0012] A method for quickly calibrating the action depth of an ultrasonic handle is also provided, comprising the following steps: placing the ultrasonic handle to be calibrated in a hydrophone for initial action depth calibration to obtain a standard action depth of preset ultrasonic energy; placing the ultrasonic handle to be calibrated in the above-mentioned ultrasonic handle action depth calibration device for secondary action depth calibration to obtain the depth of a light spot of a preset range and size formed by the ultrasonic handle on the horizontal plane of the test gel, and marking the ultrasonic handle that reaches this depth as a handle that reaches the standard action depth.

[0013] Beneficial effects: The ultrasonic handle action depth calibration device, by setting a ruler and a positioning line beside the adjusting part, can directly observe the change in the distance of the ultrasonic handle relative to the test gel in the observation slot from the height change of the relative positioning line marked by the ruler after the adjusting part adjusts the connection bracket, thereby facilitating the calibration of the action depth of the ultrasonic handle, and directly observing the changes of the test gels at different heights under the action of ultrasonic energy through the observation slot, thereby identifying the gel position corresponding to the preset ultrasonic energy, and improving the calibration accuracy of the action depth of the ultrasonic handle. In addition, by performing a secondary action depth calibration through the ultrasonic handle action depth calibration device, the depth of the ultrasonic handle forming a light spot of a preset range size on the horizontal plane of the test gel can be found, and the depth is used to calibrate the standard action depth of the ultrasonic handle placed in the hydrophone for the initial action depth calibration, thereby realizing the action depth calibration of the ultrasonic handle related to the energy size and penetration.

[0018] The present invention is further described in detail below in conjunction with specific implementation methods.

[0019] like Figure 1 As shown, the ultrasonic handle 4 action depth calibration device of this embodiment includes a mounting frame 1 for mounting the ultrasonic handle 4 and an observation tank 5, wherein the observation tank 5 is specifically a transparent water tank with at least the front side transparent. Test gel 7 and medium water 6 are placed from bottom to top in the observation tank 5, and the test gel 7 is a thermochromic gel. When the ultrasonic handle 4 is mounted on the mounting frame 1, the ultrasonic emission direction of the ultrasonic handle 4 is toward the test gel 7. The ultrasonic handle 4 of this embodiment is mounted on the mounting frame 1 in a horizontal manner. In other embodiments, see Figure 2 , the ultrasonic handle 4 is changed to be vertical.

[0020] The mounting frame 1 of this embodiment is specifically a Z-axis dovetail groove platform, and the mounting frame 1 includes a connecting bracket 2 for clamping the ultrasonic handle 4 and an adjusting member 3 for adjusting the horizontal height of the connecting bracket 2. The connecting bracket 2 serves as a slider of the Z-axis dovetail groove platform and is restricted to move in two directions of the X-axis and the Y-axis. The mounting frame 1 also includes a ruler 11 and a positioning line 12 arranged beside the adjusting member 3. The ruler 11 is a ruler with scale lines. The positioning line 12 is used to mark the height of the connecting bracket 2 relative to the bottom of the mounting frame 1. The height change value of the ruler 11 relative to the positioning line 12 after the adjusting member 3 adjusts the connecting bracket 2 is calibrated as the action depth of the ultrasonic handle 4. The adjusting member 3 is a platform adjustment knob. Turning the platform adjustment knob causes the connecting bracket 2 to rise or fall relative to the ruler 11, thereby driving the ultrasonic handle 4 to approach or move away from the test gel 7.

[0021] The ultrasonic handle 4 action depth calibration device, by arranging a scale 11 and a positioning line 12 beside the adjusting member 3, can directly observe the distance change of the ultrasonic handle 4 relative to the test gel 7 in the observation slot 5 from the height change of the relative positioning line 12 marked by the scale 11 after the adjusting member 3 is adjusted to connect the bracket 2, thereby facilitating the calibration of the action depth of the ultrasonic handle 4, and directly observing the changes of the test gel 7 at different heights under the action of ultrasonic energy through the observation slot 5, so as to identify the gel position corresponding to the preset ultrasonic energy, thereby improving the calibration accuracy of the action depth of the ultrasonic handle 4.

[0022] A detection material is provided below the installation position of the ultrasonic handle 4. The detection material is a thermochromic gel. During the calibration process of the action depth of the ultrasonic handle 4, the ultrasonic handle 4 transmits ultrasonic signals to the detection material. These signals will be reflected, scattered, etc. when penetrating the material being tested, thereby causing the thermochromic gel within the action range of the ultrasonic energy to change color. The color, shape, etc. of the thermochromic gel will change reversibly with changes in temperature. In the calibration of the action depth of the ultrasonic handle 4, this material is used as a detection material to intuitively display the action depth and energy distribution of the ultrasonic signal.

[0023] The working process of the ultrasonic handle 4 action depth calibration device of this embodiment is as follows: install the ultrasonic handle 4 on the Z-axis dovetail groove platform and ensure that its position is accurate and fixed. Place the thermochromic gel under the ultrasonic handle 4 as the detection material. Start the ultrasonic handle 4 to emit an ultrasonic signal, observe the color change of the thermochromic gel, record the position and shape of these changes, and use these records to analyze the action depth and energy distribution of the ultrasonic signal. According to the observed color changes, combined with the parameter settings of the ultrasonic equipment (such as frequency, power, etc.), the action depth of the ultrasonic handle 4 is calibrated. By adjusting the parameters of the equipment, the penetration depth and focusing effect of the ultrasonic signal can be optimized to meet different detection needs.

[0024] The installation position of the ultrasonic handle 4 is crucial, as it determines the initial emission direction and energy distribution of the ultrasonic signal, which in turn affects the penetration depth and focusing effect of the signal in the material. In this embodiment, a Z-axis dovetail groove platform is used as the mounting frame 1 of the ultrasonic handle 4. The connecting bracket 2 is embedded in the dovetail groove on the base and can slide up and down along the Z axis (vertical direction). The Z-axis dovetail groove platform provides stable vertical guidance and lateral support for the connecting bracket 2 used to fix the ultrasonic handle 4, and allows smooth movement in a single direction, so that it can achieve high-precision vertical movement, so that the ultrasonic handle 4 fixed on the mounting frame 1 can move accurately, ensuring the accuracy of the test results.

[0025] In order to achieve the best working state, the position of the connecting bracket 2 on which the ultrasonic handle 4 is mounted can be easily fine-tuned by adjusting screws or other fasteners. In this way, the position of the connecting bracket 2 can be easily adjusted to meet the needs of a specific application. In addition, since the dovetail groove has a certain self-locking ability, it can maintain the current position unchanged without external force, thereby reducing the frequency of maintenance and adjustment.

[0026] The ultrasonic handle action depth calibration device based on this embodiment can realize the rapid calibration of the ultrasonic handle, and the specific steps are described as follows.

[0027] S1. Place the ultrasonic handle to be calibrated in a hydrophone for initial action depth calibration to obtain the standard action depth of the preset ultrasonic energy.

[0028] The hydrophone is a high-precision underwater sound pressure measurement device. During the performance test and calibration of ultrasonic equipment, it can accurately capture and convert the sound wave pressure in the water into electrical signals, providing detailed and accurate sound field distribution information, which is extremely important for ensuring the safety and effectiveness of medical cosmetic or therapeutic ultrasonic equipment in practical applications. Before taking measurements, the hydrophone needs to be strictly calibrated using a standard sound source to ensure the accuracy and reliability of its measurement results. Subsequently, according to the specific working mode of the handle to be tested (such as different operating frequencies, output powers, etc.), adjust the corresponding operating parameters to ensure the smooth progress of the test process. The hydrophone can clearly identify the concentrated area of ​​ultrasonic energy, such as Figure 3 This area is indicated by a scale mark 8. This concentrated area is the effective depth range in which the ultrasonic handle can produce effective effects in actual applications, that is, the standard action depth.

[0029] S2. Place the ultrasonic handle to be calibrated in the ultrasonic handle action depth calibration device for secondary action depth calibration, obtain the depth of the ultrasonic handle forming a light spot of a preset range and size on the horizontal plane of the test gel, and mark the ultrasonic handle that reaches this depth as the handle that reaches the standard action depth.

[0030] This embodiment performs secondary action depth calibration through the ultrasonic handle action depth calibration device, and can find out the depth of the ultrasonic handle forming a light spot of a preset range and size on the horizontal plane of the test gel. This depth is used to calibrate the standard action depth of the ultrasonic handle when it is placed in a hydrophone for initial action depth calibration, thereby realizing the action depth calibration of the ultrasonic handle related to the energy size and penetration.

[0031] The above is only an implementation method of the invention, and does not limit the scope of patent protection. Those skilled in the art can make non-substantial changes or substitutions based on the invention, which still fall within the scope of patent protection.
