Description

Technical Field

[0001] The present invention belongs to the technical field of medical ultrasonic equipment, and in particular relates to an operating device for ultrasonic experiments. Background Art

[0002] Ultrasound imaging is widely used in medicine and veterinary medicine. Its safety and non-invasive nature make it a valuable tool for diagnosis and research. For example, animal ultrasound technology uses ultrasound waves to image laboratory animals (such as mice, rabbits, pigs, and dogs), enabling high-quality detection of lesions and assessment of tissue and organ function.

[0003] In existing animal ultrasound experiments, the animal's torso and limbs are often placed on an operating panel, and imaging is performed by the operator holding a handheld ultrasound probe or using a fixed bracket. However, for specific applications such as musculoskeletal ultrasound, even slight angular deviation of the probe can significantly affect the imaging results (for example, anisotropy exists in musculoskeletal ultrasound), thus requiring high stability between the probe and the object under test. Manually holding the probe makes it difficult to maintain this stability due to human factors. Operator fatigue, hand tremors, or changes in posture can introduce positional and angular errors when holding the probe, resulting in unstable ultrasound images. This makes it difficult to maintain the same position and angle during repeated experiments, affecting the repeatability and accuracy of imaging results. While the probe can be adjusted within a certain range using a fixed bracket, it typically relies on manual adjustment of the probe's fixing rod. While the probe can be moved within a certain range, precise fine-tuning is difficult, and the precise position cannot be recorded, making repeated positioning difficult.

[0004] In summary, there is an urgent need for an operating device that can maintain a stable relative position between the object to be tested and the ultrasound probe during ultrasound experiments and can repeatedly position the object, so as to improve the stability, accuracy and repeatability of ultrasound imaging and meet the needs of animal experiments and clinical applications.

[0032] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0033] Example 1 Please refer to Figure 1 , this embodiment provides an operating device for ultrasonic experiments, including a base 1, a positioning adjustment platform, an operating platform 2 and a controller 3; The positioning and adjustment platform includes two mutually orthogonal linear translation mechanisms and a rotation mechanism. The linear translation mechanism is arranged on the base 1 and includes an X-axis translation mechanism 400 and a Y-axis translation mechanism 500, which are used to achieve movement of the operating platform in the X and Y directions. The rotation mechanism 600 is arranged on the linear translation mechanism and can achieve rotational adjustment of the operating platform 2 around the vertical axis (Z axis). The operating platform 2 is provided on the horizontal rotating mechanism 600 and is used to place an object to be tested (not shown in the figure) for ultrasonic experiments. The object to be tested is located directly below the externally fixed ultrasonic probe.

[0034] Specifically, the base 1 is a flat plate, and the material can be a high-rigidity material such as stainless steel to improve the stability of the device.

[0035] The base 1 is equipped with three leveling feet 101 and two auxiliary feet 102. Two of the three leveling feet 101 are located at one end of the base 1, and one at the other end, forming a triangle. A level gauge is integrated into the base 1 to indicate the level of the base. When the device is placed on a work surface, the three leveling feet 101 can be adjusted and the bubble on the level gauge can be observed to level the device. After leveling, the two auxiliary feet 102 are flush with the work surface to increase the stability of the device.

[0036] Please refer to Figure 2 and Figure 3In this embodiment, an X-axis translation mechanism, a Y-axis translation mechanism, and a rotation mechanism constitute a positioning and adjustment platform for achieving spatial positioning adjustment of the object to be measured. The X-axis translation mechanism 4 includes a first screw seat 401, a first screw 402, a first motor 403, and a first slider 404. The first screw seat 401 is mounted on the base 1, and the first screw 402 is rotatably mounted on the first screw seat 401. The first motor 403 is disposed at one end of the first screw seat 401, and the output shaft of the first motor 403 is connected to the first screw 402. The first slider 404 is provided with a threaded hole that matches and engages with the first screw 402. The first slider 404 is disposed on the first screw 402 through the threaded hole. The first slider 404 is provided on the first screw seat 401 with two parallel guide rails that respectively move the two sides of the first screw 402. The bottom of the first slider 404 is provided with a guide groove that is slidably connected to the guide rails. The cooperation between the guide rails and the guide groove can ensure the stable movement of the first slider 404 on the first screw 402. The first motor 403 is connected to the controller 3. The rotation of the first motor 403 drives the first screw 402 to rotate, so that the first slider 404 can move back and forth along the first screw 402; a first distance coordinate scale 405 is provided on the side of the first screw seat 401, and a first pointer 406 is installed on the side wall of the first slider 404. The first pointer 406 can indicate the position coordinate of the first slider 404 on the X-axis. The Y-axis translation mechanism 500 includes a second screw seat 501, a second screw 502, a second motor 503 and a second slider 504. The second screw seat 501 is installed on the first slider 404, and the second screw 502 is rotatably installed on the second screw seat 501. The second motor 503 is set at one end of the second screw seat 501, and the output shaft of the second motor 503 is connected to the second screw 502. The second slider 504 is provided with a threaded hole that matches and engages with the second screw 502, and the second slider 504 is set on the second screw 502 through the threaded hole; two parallel guide rods are provided on the second screw seat 501, which respectively displace the two sides of the second screw 502, and the bottom of the two sliders 504 is provided with guide holes that are slidably connected to the guide rods. The cooperation between the guide rods and the guide holes can ensure the stable movement of the second slider 504 on the second screw 502. The second motor 503 is connected to the controller 3. The rotation of the second motor 503 drives the second screw 502 to rotate, thereby moving the second slider 504 along the second screw 502; a second distance coordinate scale 505 is provided on the side of the second screw seat 501, and a second pointer 506 is installed on the side wall of the second slider 504. The first pointer 506 can indicate the position coordinate of the second slider 504 on the Y axis.

[0037] Please refer to Figure 4The rotating mechanism 600 includes a turntable and a third motor 601. The turntable includes a fixed seat 602 and a rotating platform 603 that can rotate relative to each other. The fixed seat 602 is fixedly installed on the second slider 504. A mutually meshing turbine and worm are provided in the turntable. The worm is located on one side of the inner side of the fixed seat 602. One end of the worm is connected to the output shaft of the third motor 601, and the turbine is connected to the rotating platform 603; the third motor 601 is connected to the controller 3, and the third motor 601 rotates and drives the rotating platform 603 of the turntable to rotate through the transmission of the turbine and worm; a first angle scale 604 is provided on the side of the rotating platform 603, and a first indicator line is engraved on the side wall of the fixed seat 602. The first indicator line can indicate the angular coordinate of the rotating platform 603 rotating around Z.

[0038] The first motor 403 , the second motor 503 and the third motor 601 are all servo motors.

[0039] In this embodiment, both the X-axis translation mechanism 400 and the Y-axis translation mechanism 500 utilize a lead screw drive mechanism in conjunction with a high-precision servo motor to achieve fine translation adjustment of the device along the X and Y axes in the horizontal direction. The lead screw drive provides smooth transmission and self-locking performance, and in conjunction with the servo motor, it achieves micron-level motion resolution. This linear translation mechanism allows the object under test to be freely adjusted relative to the ultrasonic probe in the horizontal plane, and the translation distance can be read from the coordinate scale on the mechanism.

[0040] In this embodiment, the rotation mechanism 600 utilizes a worm gear transmission mechanism coupled with a high-precision servo motor to precisely adjust the operating platform 2's rotation about the vertical axis (Z-axis). The worm gear's self-locking function ensures that the device does not rotate or slip at any given angle, thereby firmly maintaining the set angle. The rotation mechanism 600 allows the object under test to rotate within a certain range of angles relative to the ultrasound probe about the vertical axis, thereby changing the object's position relative to the probe. The rotation angle can be visually read using a first angle scale 604. Please refer to Figure 5 and Figure 6 In this embodiment, an angle adjustment support seat 700 is installed on the top surface of the turntable. The angle adjustment support seat 700 includes a support platform 701 and a swinging platform 702. The support platform 701 is installed at the rotation center of the top surface of the turntable. Threaded holes are provided at both ends of the support platform 701, and protrusions are provided at both ends of the swinging platform 702. The protrusions are provided with through holes. Bolts pass through the through holes and are screwed into the threaded holes to lock the support platform 701 and the swinging platform 702. The protrusions are provided with a second angle scale 703. The support platform 701 is engraved with a second indicator line. Rotating the swinging platform 702 can adjust the angle of the operating platform 2 relative to the probe, that is, to adjust the angle between the object to be measured and the ultrasonic probe. The second indicator line can indicate the angle value of the swinging of the swinging platform 702.

[0041] In this embodiment, a slide groove is provided on the top surface of the swing table 702, and a slide rail that can slide along the slide groove is provided at the bottom of the operating platform 3. The side walls of the slide groove are respectively a fixed wall and a movable wall. A locking knob is provided on the movable wall. After the position of the operating platform 3 relative to the swing table 702 is determined, the slide rail can be locked in the slide groove by using the locking knob.

[0042] In this embodiment, the operating platform 2 may be a temperature-controlled platform for carrying experimental animals and adjusting their contact temperature.

[0043] Please refer to Figure 7 Specifically, the operating platform 2 has a three-layer structure. The upper layer is a plate that contacts the experimental animal's body. This plate is preferably made of titanium alloy, which has excellent thermal conductivity and biocompatibility and is used to place and secure the animal. The middle layer is a flat plate with a built-in electric heater and temperature sensor. The electric heater has stepless power adjustment capabilities and, in conjunction with the sensor, enables closed-loop temperature control. The lower layer is a base plate connected to the swing table 702, ensuring the stable installation of the temperature control platform. The electric heater and temperature sensor are both connected to the controller via cables. Through the temperature control platform, the animal can be placed in an environment close to physiological body temperature. The desired temperature (e.g., within a range of 5°C to 45°C) is preset before the experiment and maintained throughout the experiment, or adjusted as needed, to ensure animal safety and meet imaging requirements under different experimental conditions.

[0044] In this embodiment, the controller 3 is fixed to the base 1 and is connected to each motor, electric heater and temperature sensor via cables. The controller 3 includes a control circuit board and a servo motor drive module, as well as a display screen that reproduces the human-machine interface. The controller 3 can be provided with a push rod or rocker for controlling the X / Y axis translation, a knob for controlling the Z axis rotation, a temperature setting button and a temperature display screen. The operator can manually adjust the XY axis position and the angle parameters around the Z axis of the platform through the controller 3, and monitor status information such as temperature in real time. The controller 3 can reproduce a preset program and can control the operating platform 2 to automatically move from one position to the next. If repeated detection is required, it can be repeated. Controlling the positioning and adjustment platform through the controller 3 can ensure a smooth and accurate adjustment process, and the position can be locked to avoid deviation after positioning is completed. The controller 3 can be integrated with a communication module to connect to a remote operating terminal, such as a mobile phone, so that the positioning and adjustment platform can be remotely controlled via the mobile phone.

[0045] Please refer to Figure 8In this embodiment, a positioning and correction clamping mechanism 800 for clamping the object to be measured is installed on the top surface of the turntable. The positioning and correction clamping mechanism 800 includes a connecting seat 801, and at least two vertical rods 802 are provided on the connecting seat 801. The top of each vertical rod is sequentially provided with a first connecting rod 803, a second connecting rod 804 and a third connecting rod 805, and the end of the third connecting rod 805 is provided with a crab claw clamp 806; the vertical rod 802, the first connecting rod 803, the second connecting rod 804 and the third connecting rod 805 are rotatably connected by a connecting rod clamp, and the connecting rod clamp is provided with two mutually perpendicular clamping holes, and a gap is provided on the outside of the clamping hole. The vertical gap is provided with a threaded hole and a light hole. The locking bolt passes through the light hole and the threaded hole to lock the rod clamped in the clamping hole. The two clamping holes respectively clamp two adjacent rods, and the two rods are perpendicular to each other. Multi-directional and multi-angle adjustment can be achieved through three connecting rods. By positioning and correcting the clamping mechanism 800 , the object to be tested can be fixed more stably.

[0046] When the operating device for ultrasound experiments of this embodiment is used, the object to be tested is muscle bone, and the muscle bone is fixed to the operating platform 2 using adhesive. It can also be assisted by a positioning and correction clamping mechanism 800 to fix the muscle bone directly below the ultrasound probe. The ultrasound probe is aligned with the muscle bone to meet the requirements of ultrasound detection. The external ultrasound probe can be fixed by an ultrasound probe bracket fixed on the work surface. The angle adjustment support seat 700 is adjusted to a set angle to meet the angle requirement of the ultrasound probe relative to the muscle bone. The operating device can be leveled by three leveling legs 101. The first motor 403, the second motor 503 and the third motor 601 are controlled by the controller 3 so that the X-axis translation mechanism 400, the Y-axis translation mechanism 500 and the rotation mechanism 600 drive the muscle bone to a precise ultrasound detection position. The device can ensure the stability between the object to be tested and the ultrasound probe through the positioning and adjustment platform, and can achieve repeated positioning, improve the stability, accuracy and repeatability of ultrasound imaging, and meet the requirements of animal experiments and clinical applications.
