Description
Technical Field
[0001] The present invention relates to the technical field of auxiliary positioning for extracorporeal lithotripsy, and particularly to an auxiliary device for precise positioning in extracorporeal lithotripsy treatment. Background Art
[0002] Extracorporeal shock wave lithotripsy (ESWL), as a commonly used minimally invasive treatment method, is widely applied to the treatment of kidney stones. This method uses high-energy shock waves to act on the stones externally, causing them to break into small pieces, which can then be excreted through urine, avoiding the invasiveness and risks of traditional surgeries. Compared with traditional surgeries, extracorporeal lithotripsy has many significant advantages, such as less trauma, less bleeding, and faster recovery, so it has become the preferred treatment option for kidney stone patients. However, in practical applications, extracorporeal lithotripsy also faces some technical challenges, especially in terms of stone positioning and patient body size differences.
[0003] Stone positioning is a crucial step in extracorporeal lithotripsy. Accurate stone positioning can ensure that the shock wave can act precisely on the stone, maximizing the lithotripsy effect. However, traditional positioning methods mainly rely on X-ray imaging, which has obvious limitations in many cases. For certain types of stones, especially X-ray transparent stones (such as uric acid stones), X-ray imaging cannot clearly show their positions, resulting in the inability to accurately locate the stones. This means that for X-ray negative stones, traditional radiographic positioning methods will not work, thus affecting the treatment effect. Although some devices combine CT imaging or ultrasonic imaging to assist in positioning, these technologies also have their own limitations, especially the need for additional equipment support, which increases the complexity of the operation and the treatment cost.
[0004] Secondly, the difference in patient body size is also an important issue faced by extracorporeal lithotripsy. For patients with different body sizes, such as obese or large-framed people, the poor penetrability of ultrasonic waves or X-rays may affect the accuracy of stone positioning. For patients with a large body size, traditional imaging positioning techniques may not provide sufficient clarity, resulting in the inability to accurately locate the stones. In addition, patients may need to change their body positions during the treatment process to adapt to the needs of lithotripsy treatment, and different body positions and body sizes may further increase the difficulty of positioning. Therefore, the present invention proposes an auxiliary device for precise positioning in extracorporeal lithotripsy treatment to solve the problems existing in the prior art. Summary of the Invention
[0005] Aiming at the above problems, the purpose of the present invention is to propose an auxiliary device for precise positioning in extracorporeal lithotripsy treatment.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0023] In order to deepen the understanding of the present invention, the following will further elaborate on the present invention in combination with embodiments. These embodiments are only used to explain the present invention and do not constitute a limitation to the protection scope of the present invention.
[0024] During the treatment process, due to limitations in the positioning device or the positioning method, for example, when the doctor uses a manual method to operate the ultrasonic probe to move on the patient, and then when facing some parts, the patient may need to maintain a certain posture on the treatment table, which may cause discomfort to the patient, especially when the treatment time is relatively long. To reduce the patient's pain, it is necessary to improve the treatment experience through higher-precision positioning and a more comfortable treatment method.
[0025] Therefore, according to Figures 1 - 5 As shown, this embodiment proposes an extracorporeal lithotripsy treatment precise positioning assistance device, including an ultrasonic probe 1 and a multi-dimensional driving structure. The multi-dimensional driving structure includes a base 2. An installation frame 3 is installed on the base 2 through an X-axis driving component. An assembly plate 4 is installed on the installation frame 3 through a Z-axis driving component. A connection plate 5 is installed on the assembly plate 4 through a Y-axis driving component. The X-axis driving component, Y-axis driving component, and Z-axis driving component are all composed of a linear module 23. In this embodiment, the multi-dimensional driving structure is realized by the X-axis driving component, Y-axis driving component, and Z-axis driving component, so as to be able to adjust the position of the ultrasonic probe 1 in multiple dimensions. As Figure 1 shown, the X-axis driving component precisely adjusts the installation frame 3 along the X-axis direction (left and right direction), the Y-axis driving component precisely adjusts the connection plate 5 along the Y-axis direction (front and back direction), and the Z-axis driving component drives the assembly plate 4 to move along the Z-axis direction (up and down direction). Thus, the coordinated work of these components ensures that the ultrasonic probe can adjust its position in three dimensions, thereby realizing precise auxiliary positioning of the calculus.
[0026] For the linear module 23, the linear module 23 is a screw linear module. The screw linear module is a commonly used high-precision driving component that can convert rotational motion into linear motion. It is driven by a motor to provide precise linear motion. Since the body shapes, calculus positions, and depths of different patients may be different, through the multi-dimensional driving structure, the position of the ultrasonic probe can be precisely adjusted. Whether the patient is in the supine position, lateral position, or other postures, the ultrasonic probe can quickly adapt and find the best position.
[0027] The connecting plate 5 is provided with a fixed block 7 through an extension frame 6. The two ends of the extension frame 6 are both hinged with a second connecting piece 21 and fixed by a second locking piece 22. The second connecting pieces 21 at both ends are fixedly connected to the fixed block 7 and the connecting plate 5, respectively. When in use, the moving range of the device is still in a certain restricted state. Therefore, through the hinged extension frame 6, the hinged structure allows the extension frame 6 to be flexibly adjusted in the vertical direction, thereby achieving the position adjustment of the fixed block 7. Due to the adjustability of the extension frame 6, the device can provide more moving range and fine adjustment in the vertical direction, thereby enhancing the adaptability of the ultrasonic probe under complex patient body shapes, stone positions and treatment postures. In this process, the role of the second locking piece 22 is to fix the position of the second connecting piece 21, ensuring that the adjustment of the extension frame 6 can be locked in the desired position. This locking function ensures that the device will not loosen or move unnecessarily during the adjustment process, and maintains the stability and accuracy of the position of the ultrasonic probe 1.
[0028] A connecting column 8 is installed on the inner side of the fixed block 7 through a bearing, and the connecting column 8 is driven by a motor, the motor is located above the fixed block 7, and is connected to the fixed block 7 through a bracket, an arc plate 9 is installed at the lower end of the connecting column 8, and a first connecting member 10 is installed on the arc plate 9 through an adjustment component, and an ultrasonic probe 1 is installed on the first connecting member 10. Through the cooperation of the set motor and the connecting column 8, the position of the arc plate 9 can be changed in the horizontal direction, thereby adjusting the position of the ultrasonic probe 1 in the horizontal direction. It can adapt to the body shape, stone location and treatment needs of different patients, and then can cope with different stone locations, body shape differences and patient postures, providing stronger adaptability for complex cases.
[0029] As for the adjustment component, it includes a slider 16, and an arc-shaped limit opening 17 is provided on the arc-shaped plate 9. The slider 16 is located in the arc-shaped limit opening 17 and slides in the arc-shaped limit opening 17. Arc-shaped blocks 18 are installed on both sides of the slider 16, and the arc-shaped blocks 18 are fitted with the arc-shaped plate 9, so as to ensure that the slider 16 can only move along the preset track, thereby avoiding the influence of the free movement of the slider on the positioning accuracy of the device, and ensuring that the slider 16 will not shake or error when sliding, which is very important for the position adjustment of the ultrasonic probe 1. The stable sliding mechanism can effectively improve the adjustment accuracy and ensure that the position adjustment of the ultrasonic probe 1 is always on the predetermined track. The arc-shaped block 18 on one side (front side) is connected to the first connecting member 10. When the device is performing auxiliary positioning, the arc-shaped plate 9 is covered on the outside of the patient's body, ensuring that the positioning device can effectively align with the patient's target area during operation, and also facilitating the adjustment and positioning of the ultrasonic probe 1.
[0030] The arc-shaped plate 9 is provided with limiting holes 19, and several groups of limiting holes 19 are evenly arranged. A first locking member 20 is installed between the two arc-shaped sticking blocks 18, and one end of the first locking member 20 passes through a group of limiting holes 19. Further, after the position of the slider 16 is adjusted, after the first locking member 20 passes through the corresponding limiting opening 19, it is fixed, so as to achieve the effect of fixing the position of the ultrasonic probe 1. Thus, in actual operation, the ultrasonic probe 1 needs to maintain an accurate positioning to ensure the treatment effect. Therefore, through the cooperation of the first locking member 20 and the limiting holes 19, the design ensures the accurate position of the probe, and any slight vibration or accidental touch of the patient and the treatment equipment will not affect the correct positioning of the probe. Correspondingly, the first locking member 20 corresponds to a bolt, and it is self-provided with a nut.
[0031] A display control screen 11 is installed on the mounting bracket 3, and the display control screen 11 is connected to the ultrasonic probe 1. The display control screen 11 is used to display the positioning status, image feedback and operation interface of the ultrasonic probe 1 in real time. The operator can view the ultrasonic image through the display screen, monitor the position of the stone, and adjust the position or operation parameters of the ultrasonic probe as needed.
[0032] The first connecting member 10 is provided with a notch, and the notch is adapted to the ultrasonic probe 1. Sockets 12 are provided on both sides inside the first connecting member 10, and the sockets 12 communicate with the notch. Plug blocks 13 are installed on both sides of the ultrasonic probe 1, and the plug blocks 13 are located inside the sockets 12. A stop block 14 is installed on the first connecting member 10, and a contact block 15 is installed on the stop block 14 through a spring, and the contact block 15 contacts the ultrasonic probe 1. When in use, in order to avoid the ultrasonic probe 1 applying a large pressure to the patient, a spring is provided. Through the cooperation of the spring and the contact block 15, an elastic pressure is applied to the ultrasonic probe 1, which helps to improve the comfort of the patient. Correspondingly, the stop block 14 and the first connecting member 10 are connected by screws, and it is a detachable design, which is convenient for the installation and disassembly of the ultrasonic probe 1.
[0033] Load-bearing blocks 24 are installed on the base 2, and several groups of load-bearing blocks 24 are provided. The lower end of the mounting bracket 3 is installed with limiting rails 25. The number and position of the limiting rails 25 correspond to those of the load-bearing blocks 24. The upper ends of the load-bearing blocks 24 are located inside the limiting rails 25. By setting the cooperation of the load-bearing blocks 24 and the limiting rails 25, it is convenient to provide better support for the base 2. At the same time, a fixing seat 26 is installed at the lower end of the base 2, and the fixing seat 26 is hollow. The fixing seat 26 is used to connect with external equipment.
