Description

Technical Field

[0001] The invention relates to the technical field of ultrasonic transducer detection, and in particular to an ultrasonic transducer calibration detection device applied to medical ultrasonic diagnosis. Background Art

[0002] The simulation and calibration test of ultrasonic transducers (ultrasound probes) in medical ultrasonic diagnosis is an important part of ensuring the quality of ultrasonic images and the accuracy of diagnosis. Through simulation, the performance of the transducer can be predicted in the design stage, its structure and function can be optimized, and the imaging quality can be improved.

[0003] After searching, announcement number CN118067853B discloses an ultrasonic transducer detection device under a simulation environment, including a simulation environment model, a central rotating component, an integrated adjustment test component and a computer test system. The simulation environment model includes an electromagnetic radiation cavity, a high-temperature cavity and a biological fluid-simulating cavity. The rotating shell in the central rotating component is movably connected in the central cavity. The first driving member is transmission-connected to the central tube. Four linear guide rails are arranged on the surface of the rotating shell. The accommodating groove in the integrated adjustment test component is used to place the ultrasonic transducer. The driving part is transmission-connected to the second tooth groove to drive the ultrasonic transducer into the feeding cavity, the electromagnetic radiation cavity, the high-temperature cavity or the biological fluid-simulating cavity. The computer test system is electrically connected to the ultrasonic transducer to detect the operating parameters or imaging quality of the ultrasonic transducer. It has the characteristics of easy use, high test efficiency and more comprehensive, systematic and real test data.

[0004] The ultrasonic transducer detection device disclosed above sequentially places the ultrasonic probe in multiple environments that affect its imaging quality for detection and obtains detection results. Although it can obtain more comprehensive test data, it still has the following defects: (1) The detection angle of the ultrasonic probe in each test environment cannot be adjusted. However, in actual use, the angle at which the ultrasonic probe emits ultrasonic waves is not fixed. For example, the ultrasonic knife probe used in surgery and the vaginal probe used for gynecological examinations all need to be continuously adjusted during use to obtain more comprehensive image data of internal organs or tissues. (2) Considering that different types of ultrasonic probes have different data plugs, an adapter is generally required for conversion. The ultrasonic probe uses its own data plug to insert into the data interface of the adapter. Due to the limitation of the length of the data plug, the adapter and the ultrasonic probe need to be immersed in the tissue fluid for detection (the principle of immersion in a simulated biological fluid cavity for detection is consistent with the principle of water bath testing. Both simulate the propagation and reflection of ultrasound in tissues or liquids, and predict the image quality by evaluating the sound field distribution of the transducer at different frequencies and in different media). In this way, due to the different shapes of ultrasonic probes of different models, the installation of the ultrasonic probe must meet the basic condition of easy disassembly and assembly. The existing clamping and fixing structure cannot simultaneously provide stable support and good sealing for ultrasonic probes of different models. The connection between the ultrasonic probe and the adapter is easily affected by moisture and affects the test results. If the adapter and the ultrasonic probe are installed together in a sealed shell, it will affect the ultrasonic emission of the ultrasonic probe, so it cannot meet the calibration detection of ultrasonic probes of different models.

[0037] In the embodiment of the present invention, the adapter 2 ensures that different models or types of ultrasonic probes 10 are compatible with a specific ultrasonic system, so as to perform effective signal transmission and data acquisition. The adapter 2 can conveniently connect different models of ultrasonic probes 10 with different plug shapes and pins. When the ultrasonic probe 10 is running at high power for detection, the heat generated by the adapter 2 can be directly transferred to the water bath through the heat dissipation fins 121, and has the characteristics of good heat dissipation effect. A through hole 18 connected to the hollow shaft 17 is provided on the inner side of the interlayer 14.

A wireless data transmission module can also be installed on the inner side of the hollow shaft 17, which solves the problem that the wireless data transmission module cannot be used to transmit data to the computer software system in a sealed environment.

[0038] Working principle: Preparation before testing: First, use the knob 321 to control the worm 32, the worm wheel 312 and the inner shell 31 to rotate clockwise to open the No. 1 opening 13 or control the No. 2 opening 311 to rotate toward the No. 1 opening 13. The clockwise rotating inner shell 31 uses the fixed pin 313 and the protrusion 412 to control the transmission ring 41 to rotate 180 degrees synchronously. The clockwise rotating transmission ring 41 drives the movable pin 422 along the radial guide rail 151 toward the axis away from the outer shell 11 through the arc guide rail 411. The elastic member 152 is in a compressed state at this time, so the plurality of clamping members 42 moving radially can drive the elastic sealing ring 43 to expand or make a movement with a larger caliber, and then the ultrasonic probe 10 is placed inside the elastic sealing ring 43, and the corresponding data socket is selected according to the data plug model of the ultrasonic probe 10 to connect with the adapter 2; then the knob 321 is used to control the worm 32 to rotate 180 degrees counterclockwise, which is used to control the inner shell 31 to seal the No. 1 opening 13, and the fixing pin 32 rotates counterclockwise. 13 will not control the synchronous movement of the protrusion 412, so the transmission ring 41 without the fixed pin 313 is driven to move radially under the dual elastic force of the elastic member 152 and the elastic sealing ring 43, and the special-shaped clamping piece 421 that moves radially drives the transmission ring 41 to rotate counterclockwise using the movable pin 422 and the arc guide rail 411. On the one hand, the special-shaped clamping piece 421 made of rigid material and the elastic sealing ring 43 made of flexible material can ensure the stability of the clamping of the ultrasonic probe 10 and the sealing of the connection between the ultrasonic probe 10 and the housing 11, thereby preventing the problem of moisture affecting the calibration test result during the water bath test. On the other hand, not only can the No. 1 opening 13 and the elastic sealing ring 43 be opened at the same time to install the ultrasonic probe 10, but also the special-shaped clamping piece 421 and the elastic sealing ring 43 can adaptively clamp and seal the ultrasonic probe 10 while closing the No. 1 opening 13, and have the characteristics of adaptively clamping and fixing ultrasonic probes 10 of different models and good sealing effect.

[0039] Calibration and detection link: first, use the water inlet pipe 51 to input impurity-free water of a certain temperature into the water bath test box 5, use the water level sensor 54 to monitor the liquid level, and then use the temperature and humidity sensor 53 to monitor the temperature and humidity parameters inside the water bath test box 5 respectively, so as to ensure that the temperature and humidity parameters are within a certain threshold range, and prevent the formation of bubbles in the water due to the high temperature and humidity environment, because the existence of bubbles will change the propagation characteristics of sound waves on the interface between water and gas, thereby affecting the measurement results of the transducer, and then use the lateral displacement module 6 and the longitudinal displacement module 7 to adjust the coordinate position of the ultrasonic probe 10, so as to align the ultrasonic emission port of the ultrasonic probe 10 with the central mark point on the surface of the sample block 9 to be tested, and then use the ultrasonic generator inside the ultrasonic probe 10 to send an ultrasonic wave to the sample block 9 to be tested. The ultrasonic wave signal is received by the ultrasonic receiver inside the ultrasonic probe 10 and converted into an electrical signal. The electrical signal is transmitted to the computer analyzer through the adapter 2 and the data transmission line 16. Then the angle adjustment module 8 is used to control the ultrasonic probe 10 to rotate a certain angle with the hollow shaft 17 as the axis, and the above method is used to transmit the signal to the sample block 9 to be tested again. The detection data is collected by adjusting the angle of the ultrasonic probe 10 multiple times. It should be noted that between two tests, the water level sensor 54 is needed to monitor the water level change or water level disturbance parameter in real time. When the water level disturbance parameter is within a certain threshold range, the next detection can be performed. The computer analyzer is used to process and analyze the ultrasonic data, generate test results and reports, and ensure the accuracy of the measurement based on the calibrated ultrasonic measurement system.

[0040] In summary, the present application utilizes the structural coordination among the shell assembly 1, the sealing portion 3 and the clamping portion 4, which can not only open the No. 1 opening 13 and the elastic sealing ring 43 by controlling the simultaneous rotation of the inner shell 31 and the transmission ring 41 through the worm 32, so as to facilitate the connection of different types of ultrasonic probes 10 with the adapter 2, but also can close the No. 1 opening 13 while the special-shaped clamping piece 421 and the elastic sealing ring 43 can adaptively clamp and seal the ultrasonic probe 10. The special-shaped clamping piece 421 made of rigid material and the elastic sealing ring 43 made of flexible material can ensure the stability of the clamping of the ultrasonic probe 10 and the sealing of the connection between the ultrasonic probe 10 and the shell 11, thereby preventing the problem of affecting the calibration test results due to moisture during the water bath test, and has the characteristics of adaptively clamping and fixing ultrasonic probes 10 of different types and good sealing effect.
