Description

Technical Field

[0001] The present application relates to the technical field of ultrasonic transducer sound field testing, and in particular to a flexible ultrasonic transducer sound field testing clamping tool. Background Art

[0002] Flexible ultrasonic transducers are widely used in medical devices, especially in ultrasonic imaging, diagnostic and therapeutic equipment. In order to ensure the performance of ultrasonic transducers in practical applications, their acoustic field characteristics must be accurately tested. At present, the water tank method is a common method for testing the acoustic field of ultrasonic transducers. This method uses water as the medium for sound wave propagation and evaluates its performance by measuring the acoustic field distribution of ultrasonic waves emitted by the transducer in water. Especially in the field of medical equipment, the water tank method has become a standard method for transducer performance verification because it can simulate the sound wave propagation characteristics in human tissue.

[0003] In the related art, the transducer guide wire is usually clamped and fixed by a clamp so that the probe at the end of the transducer guide wire is immersed in the water in the water tank. The transducer emits sound waves through the probe, and the receiver in the water tank monitors the sound wave characteristics in real time and records the sound wave propagation characteristics in the water.

[0004] In the above-mentioned related technologies, since the transducer guide wire is usually flexible, when it is clamped with an ordinary clamp, the transducer guide wire is very easy to bend, which makes it difficult to accurately control the position and angle of the transducer probe, resulting in large errors in the sound field test data of the flexible ultrasonic transducer.

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] The present application discloses a flexible ultrasonic transducer acoustic field test fixture. The fixture is used in a water tank method to test the acoustic field of the transducer. Specifically, the guide wire of the transducer is inserted into the water in the water tank through the fixture, and the probe 61 of the transducer is located on one side of the end of the guide wire (such as Figure 5As shown), the sound wave sensor in the water tank is fixed on the side wall of the water tank. When the probe 61 of the transducer guide wire 6 is facing the sound wave sensor, it is the maximum output power point of the probe 61. This process requires controlling the transducer guide wire 6 to adjust the position and angle to a certain extent. The clamping tooling of the present application can accurately position the transducer guide wire 6 and control the transducer guide wire 6 to adjust to the required position and angle.

[0027] For details, please refer to Figure 1 The flexible ultrasonic transducer sound field test clamping tooling includes a mounting seat 1, a connecting rod 11, a clamping member 2, a guide rod 3, an adjustment device 4 and an auxiliary positioning device 5. The mounting seat 1 is a rectangular plate. One end of the connecting rod 11 is connected to the mounting seat 1, and the other end is connected to the clamping member 2. The clamping member 2 is located below the mounting seat 1. The connecting rod 11 can increase the distance between the clamping member 2 and the mounting seat 1 to facilitate the clamping member 2 to carry the ultrasonic transducer into the water tank. A guide wire channel 211 is vertically opened inside the clamping member 2 for the transducer guide wire 6 to pass through, which is used to clamp and fix the transducer guide wire 6 in the guide wire channel 211. Please refer to Figure 2 The clamping member 2 includes a rectangular clamping seat 21, a flexible clamping block 22 arranged on the clamping seat 21, and a toggle clamp 23. The guide wire channel 211 is located at the center of the clamping seat 21. A notch 212 is provided on the side of the clamping seat 21 for the transducer guide wire 6 to pass through the guide wire channel 211. The flexible clamping block 22 is located below the notch 212. The flexible clamping block 22 is pushed by the toggle clamp 23, so that the flexible clamping block 22 can be compressed, thereby clamping and fixing the transducer guide wire 6. The guide rod 3 is arranged below the clamping member 2. The guide rod 3 is a round rod arranged vertically. A guide hole coaxially arranged with the guide wire channel 211 is provided inside the guide rod 3. The guide hole is used to limit the circumference of the transducer guide wire 6. The guide rod 3 is provided with a chamfer at one end of the guide hole close to the guide channel, and the maximum diameter of the chamfer is greater than the diameter of the guide channel, so as to facilitate the transducer guide wire 6 to enter the guide hole from the guide channel. In this embodiment, the transducer uses a 1mm guide wire, the diameter of the guide hole is slightly larger than the diameter of the transducer guide wire 6, and the inner wall of the guide hole is made of smooth materials such as polyurethane, aluminum alloy or ceramic, so as to reduce the friction resistance of the transducer guide wire 6 passing through the guide hole. The adjustment device 4 is used to control the movement or rotation of the clamping member 2, so as to adjust the position and angle of the probe 61 at the end of the clamped transducer guide wire 6. The auxiliary positioning device 5 is arranged on the mounting seat 1, and is used to position the transducer guide wire 6 passing through the guide rod 3 to a vertical state, reducing the possibility of bending of the transducer guide wire 6, thereby effectively improving the accuracy of the position and angle control of the transducer probe 61, and greatly reducing the error of the sound field test of the flexible ultrasonic transducer.

[0028] During the flexible transducer sound field test, the transducer guide wire 6 is inserted into the guide wire channel 211 of the clamping member 2, and the transducer guide wire 6 is inserted into the guide rod 3 through the guide wire channel 211. A guide hole with a smooth inner wall is arranged in the guide rod 3 to limit the circumference of the transducer guide wire 6 while reducing the obstruction to the movement of the transducer guide wire 6 along the guide hole. After the transducer guide wire 6 passes through the guide rod 3, the auxiliary positioning device 5 positions the transducer guide wire 6 to a vertical state, and the clamping member 2 clamps and fixes the transducer guide wire 6, so that the transducer guide wire 6 remains in a vertical state, so that when the adjusting device 4 controls the clamping member 2 to move or rotate, the probe 61 at the end of the transducer guide wire 6 can maintain a relatively ideal state, thereby effectively reducing the error of the flexible transducer sound field test.

[0029] For details, please refer to Figure 1 and Figure 3 The auxiliary positioning device 5 includes a positioning bracket 51 and a positioning cross bar 52. The positioning bracket 51 is a vertically arranged rectangular rod. One end of the positioning bracket 51 is fixedly connected to the mounting seat 1 by bolts, and the other end is fixedly connected to the positioning cross bar 52 by bolts. The positioning cross bar 52 is located below the guide rod 3. A positioning hole coaxial with the guide hole is opened on the positioning cross bar 52. A guiding fillet is opened at the top of the positioning hole of the positioning cross bar 52, so that the transducer guide wire 6 passing through the guide rod 3 can smoothly pass into the positioning hole under the action of the guiding fillet. Since the positioning hole is coaxial with the guide hole and the guide channel, the transducer guide wire 6 passing through the guide rod 3 is kept in a vertical state under the action of the positioning cross bar 52, reducing the possibility of bending of the transducer guide wire 6, so that the transducer probe 61 can face the sound wave receiver located on the side wall of the water tank, thereby reducing the error of the sound field test.

[0030] Since the transducer guide wire 6 is made of flexible material, the transducer guide wire 6 is easily bent under the water pressure at the moment of contacting the water surface, causing the initial angle of the probe 61 to tilt. Therefore, it is necessary to protect the end of the transducer guide wire 6 to reduce the possibility of bending when the end of the transducer guide wire 6 enters the water. Specifically, the auxiliary positioning device 5 also includes a guide wire sheath 53 and a drive assembly 54. The guide wire sheath 53 is a tube with an inner diameter slightly larger than the transducer guide wire 6. The guide wire sheath 53 is slidably arranged under the positioning cross bar 52 between the protection state and the storage state, and is coaxially arranged with the positioning hole. When in the protection state, the guide wire sheath 53 can wrap the end of the transducer guide wire 6, thereby reducing the possibility of bending when the transducer guide wire 6 enters the water; when in the storage state, the guide wire sheath 53 slides to abut against the positioning cross bar 52, so that the transducer probe 61 is exposed in the water, which is convenient for the transducer probe 61 to transmit sound waves toward the sound wave receiver. The driving assembly 54 is used to drive the guide wire sheath 53 to slide, so that the guide wire sheath 53 is switched between a protection state and a storage state.

[0031] During the process of the guide wire sheath 53 being transferred from the protective state to the storage state, the guide wire sheath 53 slides upward from the end of the transducer guide wire 6, which can straighten the transducer guide wire 6, so that the guide wire sheath 53 can not only reduce the possibility of bending of the end of the transducer guide wire 6 when entering the water, but also can straighten the transducer guide wire 6, further reduce the accuracy of the position of the probe 61, and thus reduce the error of the sound field test.

[0032] One end of the guide wire sheath 53 near the positioning cross bar 52 is provided with a bell mouth, which can facilitate the transducer guide wire 6 to enter the guide wire sheath 53 from the positioning hole. In order to buffer the impact caused by the contact between the guide wire sheath 53 and the positioning cross bar 52 when the guide wire sheath 53 enters the storage state, the guide wire sheath 53 is set to an elastic material, and the elastic material includes but is not limited to silicone or rubber, etc. The bell mouth set by the elastic material can also form a seal between the guide wire sheath 53 and the positioning cross bar 52, reducing the possibility that the water flow disturbs the transducer guide wire 6 from the gap between the guide wire sheath 53 and the positioning cross bar 52 when the position and angle of the transducer guide wire 6 are adjusted.

[0033] Please refer to Figure 3 and Figure 4 In order to facilitate the driving component 54 to control the guide wire sheath 53 from the protection state to the storage state, the driving component 54 can be electric or manual, but the electric driving method or the manual driving method will cause a complex structure and inconvenient operation. Because in this embodiment, the driving component 54 uses water buoyancy as a power source to drive the guide wire sheath 53 into the storage state.

[0034] Specifically, the drive assembly 54 includes a limit rod 541, a return spring 542 and a buoyancy member 543. The limit rod 541 is an L-shaped rod. One end of the limit rod 541 is fixedly connected to the side wall of the guide wire protective tube 53, and the other end penetrates from the bottom of the positioning cross bar 52 and passes out from the top of the positioning cross bar 52. The limit rod 541 is slidably connected to the positioning cross bar 52 along the sliding direction of the guide wire protective tube 53. The end of the limit rod 541 protruding from the positioning cross bar 52 is fixed with a mounting disk, and the mounting disk is a circular disk. The return spring 542 is sleeved on the limit rod 541, one end of the return spring 542 is fixedly connected to the top surface of the positioning cross bar 52, and the other end is fixedly connected to the mounting disk. The return spring 542 pulls the mounting disk to drive the limit rod 541 and the guide wire protective tube 53 to move away from the positioning cross bar 52, so that the guide wire protective tube 53 enters a protective state. The buoyancy member 543 is a hollow floating ball or a hollow floating block, and the buoyancy member 543 is fixedly connected to the mounting plate.

[0035] After the transducer guide wire 6 enters the water, the guide wire sleeve 53 is in a protective state. Figure 3As shown, the possibility of bending of the transducer guide wire 6 is effectively reduced. As the buoyancy member 543 enters the water, the buoyancy member 543 drives the guide wire sleeve 53 to slide upward under the action of the water buoyancy. Figure 4 As shown, the guide wire sheath 53 is put into the storage state, the structure is relatively simple, and the guide wire sheath 53 is automatically controlled to enter the storage state through water buoyancy, thereby ensuring the high accuracy of the ultrasonic transducer sound field test while greatly improving the convenience of the sound field test.

[0036] In order to improve the stability of the guide wire sheath 53 when it slides, two groups of drive assemblies 54 are provided. The two groups of drive assemblies 54 are symmetrically arranged on both sides of the guide hole, so that the two limit rods 541 can limit the guide wire sheath 53 at the same time to improve the stability of the guide wire sheath 53 when it slides, and the two reset springs 542 and the two buoyancy members 543 can increase the response speed of the guide wire sheath 53 and reduce the possibility of the guide wire sheath 53 floating during movement.

[0037] Please refer to Figure 6The adjusting device 4 includes an adjusting bracket, a sliding seat 42, a first rotating seat 43 and a second rotating seat 44. The adjusting bracket is not shown in the figure. The adjusting bracket is mounted above the water tank. The adjusting bracket is provided with a slide rail support 411 and a transverse slide rail 412. The slide rail support 411 is provided with two slide rails spaced apart in the transverse direction. The adjusting bracket is provided with a lifting drive, which includes but is not limited to a sprocket chain mechanism or a motor screw mechanism. The slide rail support 411 is lifted and adjusted by the lifting device, thereby driving the transverse slide rail 412 to lift and lower. The transverse slide rail 412 includes two parallel sliding rods. The ends of the two sliding rods are connected by a rectangular block, so that the two sliding rods are connected as a whole. The sliding rod simultaneously passes through the two slide rail supports 411 and is slidably connected with the slide rail supports 411 in the transverse direction, so that the position of the transverse slide rail 412 can be adjusted, so that the sliding block can enter the range of the water tank. The sliding seat 42 is a rectangular block. The sliding seat 42 is slidably connected to the adjustment bracket in the horizontal direction through the transverse slide rail 412. The sliding seat 42 is provided with a plurality of locking bolts, and the sliding seat 42 can be firmly locked on the transverse slide rail 412 through the locking bolts. The first rotating seat 43 and the second rotating seat 44 are both circular turntables. The first rotating seat 43 is rotatably connected to the sliding seat 42, and the rotation axis is in the horizontal direction and perpendicular to the sliding direction of the sliding seat 42. A connecting plate 48 is fixed on the first rotating seat 43. The mounting seat 1 is fixedly connected to the connecting plate by bolts. The second rotating seat 44 is rotatably connected to the mounting seat 1, and the rotation axis is arranged in the vertical direction. The clamping member 2 is connected to the second rotating seat 44 through the connecting rod 11, and the rotation axis of the second rotating seat 44 is coaxially arranged with the guide wire channel 211. A first coarse adjustment dial is provided on the side wall of the first rotating seat 43, and a second coarse adjustment dial is provided on the side wall of the second rotating seat 44. The angle of the probe 61 can be preliminarily adjusted by turning the first coarse adjustment dial and the second coarse adjustment dial. It should be noted that dampers are provided on the rotating shafts of the first rotating seat 43 and the second rotating seat 44 to reduce the possibility of the first rotating seat 43 and the second rotating seat 44 rotating without human control.

[0038] By controlling the slide rail support 411 to rise and fall, the transverse slide rail 412 drives the mounting seat 1 to rise and fall, so that the connecting rod 11 connected to the mounting seat 1 drives the transducer guide wire 6 to extend into the water tank, and then the transducer guide wire 6 is controlled to adjust the angle by rotating the first rotating seat 43 and the second rotating seat 44, so that the probe 61 is initially aligned with the sound wave receiver in the water tank.

[0039] In order to control the distance between the clamping member 2 and the mounting seat 1 so that the probe 61 is kept at the same height as the sound wave receiver in the water tank, a through hole is provided on the mounting seat 1 for the connecting rod 11 to pass through. The connecting rod 11 can slide freely in the vertical direction and can rotate on its own. A locking member 45 is provided on the second rotating seat 44. The locking member 45 is a clamp. Before performing the sound field test, the clamping member 2 is made to reach the required height by sliding the connecting rod 11, and then the connecting rod 11 is locked by the locking member 45, so that the clamping member 2 can be quickly positioned.

[0040] To further improve the accuracy of the probe 61 angle, please refer to Figure 7 A first fine-tuning assembly 46 for fine-tuning the rotation of the first rotating seat 43 is provided between the first rotating seat 43 and the sliding seat 42, and a second fine-tuning assembly 47 for fine-tuning the rotation of the second rotating seat 44 is provided between the second rotating seat 44 and the first rotating seat 43. Figure 6 The first fine-tuning assembly 46 includes a fine-tuning support 461, a fine-tuning stop block 462, a fine-tuning turntable 463, a micrometer head 464, and a fine-tuning push rod 465. The fine-tuning support 461 and the fine-tuning turntable 463 are both disc-shaped. The fine-tuning support 461 is arranged vertically and is fixedly connected to the sliding seat 42. The fine-tuning turntable 463 is coaxially arranged with the fine-tuning support 461 and is rotatably connected to the fine-tuning seat. The first rotating seat 43 is coaxially rotatably connected with the fine-tuning turntable 463. The fine-tuning stop block 462 is a U-shaped block, that is, a stop groove is provided on the fine-tuning stop block 462, and the notch of the stop groove faces the fine-tuning turntable 463. A fine-tuning lever 4631 is fixed on the side wall of the fine-tuning turntable 463, and the fine-tuning lever 4631 is located in the stop groove of the fine-tuning stop block 462. The micrometer head 464 and the fine adjustment push rod 465 are both arranged on the fine adjustment limit block 462. The micrometer head 464 and the fine adjustment push rod 465 are arranged in the same line and are respectively located on both sides of the fine adjustment lever 4631. The fine adjustment lever 465 moves toward the micrometer head 464 through an elastic driving member such as a spring, so that the fine adjustment lever 4631 is clamped between the fine adjustment push rod 465 and the micrometer head 464. By twisting the dial of the micrometer head 464, the movable end of the micrometer head 464 pushes the fine adjustment push rod 465, and the fine adjustment of the first rotating seat 43 can be achieved. The working principle of the second fine adjustment component 47 is the same as that of the first fine adjustment component 46, which will not be repeated here.

[0041] After the angle of the probe 61 is preliminarily adjusted by the first coarse adjustment lever 431 and the second coarse adjustment lever 441, the first rotating seat 43 and the second rotating seat 44 are fine-tuned by the first fine-adjustment component 46 and the second fine-adjustment component 47, and then the angle of the probe 61 can be fine-tuned, so that the maximum output power point of the flexible ultrasonic transducer probe 61 or the corresponding power position required for the experiment can be accurately found, so that it can be accurately aligned with the sound wave receiver, and the performance test of the flexible ultrasonic transducer probe 61 can be completed.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
