Description

Technical Field

[0001] This utility model relates to the field of ultrasonic puncture technology, and in particular to an easy-to-operate medical ultrasonic puncture frame. Background Technology

[0002] Medical ultrasound is a technology that uses ultrasound waves for diagnosis and treatment of the human body. It is used to diagnose the morphology, structure, and lesions of internal organs, such as observing fetal development and examining abdominal and cardiovascular diseases. It is also used in treatments such as ultrasound-guided interventional procedures and high-intensity focused ultrasound (HIFU) for tumor treatment. The puncture frame mechanism is an auxiliary device for ultrasound-guided puncture procedures, typically including a fixation device, an angle adjustment mechanism, a depth adjustment mechanism, and a puncture needle guide mechanism. Its working principle is that it is installed on the ultrasound probe to fix the angle and direction of the puncture needle. The doctor observes the target based on the ultrasound image and guides the puncture needle along the puncture frame into the body, ensuring puncture accuracy.

[0003] When performing ultrasound-guided punctures, a medical ultrasound puncture frame is first installed on the ultrasound probe, and the angle and depth of the puncture needle are adjusted as needed. Then, the doctor places the ultrasound probe on the patient's body surface and observes the location of the target tissue using ultrasound images. After determining the puncture path, the doctor inserts the puncture needle into the body along the guide mechanism of the puncture frame, adjusting the direction and depth of the needle under real-time ultrasound monitoring until the target location is reached. The purpose of the puncture frame is to ensure the accuracy and stability of the puncture needle, reducing the risks and complications of puncture.

[0004] However, in existing technologies, some medical ultrasound puncture frames have poor compatibility with puncture needle models. There are numerous models and specifications of puncture needles, and the puncture needle guiding structure of the puncture frame is often designed for specific needle models, which may not be well-suited for other needle models. This results in significant resistance during passage, affecting the smoothness of the operation; some thinner puncture needles may also wobble within the guide hole, leading to inaccurate puncture direction. Therefore, this paper proposes an easier-to-use medical ultrasound puncture frame to solve these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an easy-to-operate medical ultrasound puncture frame, aiming to improve the problem of poor compatibility of puncture needle models in existing medical ultrasound puncture frames.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a medical ultrasound puncture frame that is easy to operate, comprising a functional ring one, a limiting bolt one threadedly connected to the inner wall of the top of the functional ring one, a guide tube threadedly connected to the bottom of the limiting bolt one, a plurality of fixing pads fixedly connected to the middle part of the guide tube, fixing bolts one fixedly connected to the top of the plurality of fixing pads respectively, a functional ring two threadedly connected to the outer top of the plurality of fixing bolts one, a support plate fixedly connected to the bottom of the functional ring two, a limiting plate rotatably connected to the bottom of the support plate, stabilizing plates fixedly connected to both sides of the limiting plate respectively, stabilizing bolts threadedly connected to the adjacent side of the two stabilizing plates, a base plate fixedly connected to the bottom of the limiting plate, and an adjustment component fixedly connected to the bottom of the base plate.

[0007] As a further description of the above technical solution: the adjustment component includes a functional plate one, the top end of the functional plate one is fixedly connected to the bottom end of the base plate, the bottom end of the functional plate one is slidably connected to a functional plate two, the external threads of the functional plate two are connected to a plurality of fixing bolts two, the bottom ends of two fixing bolts two are threadedly connected to a movable plate one, and the bottom ends of two fixing bolts two are threadedly connected to a movable plate two.

[0008] As a further description of the above technical solution: one side of the movable plate one is slidably connected to the interior of the functional plate two, and one side of the movable plate two is slidably connected to the interior of the functional plate two.

[0009] As a further description of the above technical solution: one side of the movable plate one is slidably connected to the top of the inner wall of the functional plate one, and one side of the movable plate two is fixedly connected to an instrument.

[0010] As a further description of the above technical solution: the bottom end of the first functional ring is fixedly connected to the top end of the support plate, and the top ends of the two stabilizing plates are both fixedly connected to the bottom end of the support plate.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the guide tube is restricted by the movement of the first functional ring via the first limiting bolt. The fixing pad on the guide tube cooperates with the second functional ring using the first fixing bolt to provide stability. The support plate can move with the second functional ring, and the limiting plate at its bottom can rotate relative to the support plate to achieve angle adjustment. The stabilizing plates on both sides further stabilize the position of the limiting plate with stabilizing bolts. The bottom plate at the bottom of the limiting plate provides support for the entire structure, thereby achieving the functions of restricting the puncture needle and adjusting its angle.

[0016] 2. In this utility model, by adjusting function plate one and function plate two, function plate one slides inside function plate two. By rotating multiple fixing bolts two, moving plate one and moving plate two are driven to move, thereby realizing the adjustment of their positions. At the same time, the limiting bolts two on both sides of the bottom of function plate one can be used for corresponding restriction. The instrument is fixedly connected to one side of moving plate one. The size of the relevant parts of the instrument is adjusted by the cooperation of various structures, thereby solving the problem of the probe size not matching the puncture frame size.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 2 to 4 This utility model provides an embodiment of an easy-to-operate medical ultrasound puncture frame. Functional ring 1 serves as the basic component, with a limiting bolt 2 on its inner top wall threadedly connected to a guide tube 3. Rotating the limiting bolt 2 allows for precise adjustment of the guide tube 3's height, facilitating accurate determination of the initial height of the puncture needle and improving puncture accuracy. A fixing pad 4 and a fixing bolt 5 in the middle of the guide tube 3 are connected to functional ring 6. The fixing pad 4 increases the stability of the connection between the guide tube 3 and functional ring 6, preventing the guide tube 3 from shaking and ensuring the smooth movement of the puncture needle within the guide tube 3. A support plate 7 at the bottom of functional ring 6 provides support for the underlying structure. A limiting plate 8, rotatably connected to its bottom, can rotate flexibly around the connection point, allowing for angle adjustment to accommodate different puncture angle requirements and expanding the puncture frame's application range. Stabilizing plates 9 and stabilizing bolts 10 on both sides of the limiting plate 8 can be tightened after the limiting plate 8 is adjusted to a suitable angle, preventing angle changes during puncture and further enhancing the stability and reliability of the puncture operation. The base plate 11 at the bottom of the limiting plate 8 serves as a load-bearing component, and the adjustment component fixed at its bottom can further adjust other functions of the puncture frame.

[0025] Reference Figures 2 to 4 Functional plate 12 is securely fixed to the bottom of base plate 11 at its top, serving as the basic support for the entire adjustment assembly and ensuring a stable foundation for subsequent structures. The bottom of functional plate 12 is slidably connected to functional plate 2 13, allowing functional plate 2 13 to slide smoothly relative to functional plate 12, thus enabling length adjustment to adapt to different usage scenarios or operational needs and increasing the flexibility of the puncture frame. Multiple fixing bolts 2 14 are externally threaded onto functional plate 2 13. When the fixing bolts 2 14 are rotated, their bottom ends can be threadedly connected to movable plates 1 15 and 2 16. Movable plates 1 15 and 2 16 can adjust their relative distance to functional plate 2 13 by rotating the fixing bolts 2 14, thereby enabling clamping or loosening operations on some auxiliary components or instruments.

[0026] Reference Figures 1 to 3One side of the movable plate 15 is slidably connected to the interior of the functional plate 13. This sliding connection allows the movable plate 15 to move smoothly back and forth within the functional plate 13, providing a basis for subsequent precise position adjustments and preventing shaking during movement, thus ensuring stability when connected to other components. One side of the movable plate 16 is slidably connected to the interior of the functional plate 13, operating on a similar principle. An instrument 18 is fixedly connected to one side of the movable plate 16. This sliding connection between the movable plate 16 and the functional plate 13 allows for easy adjustment of the instrument 18's position, enabling it to function better and adapt to different operational needs. The bottom end of the functional ring 1 is fixedly connected to the top end of the support plate 7, creating a stable upper frame for the entire puncture frame. This ensures tight and reliable connections between components, facilitating force transmission and dispersion, and preventing structural deformation during puncture operations. The tops of both stabilizing plates 9 are fixedly connected to the bottom of the support plate 7, enhancing the stability of the connection between the limiting plate 8 and the support plate 7. This effectively prevents the limiting plate 8 from accidentally loosening or shifting during angle adjustment or puncture, ensuring the accuracy and stability of the puncture angle. One side of the moving plate 2 16 is slidably connected to the inside of the functional plate 1 12, further restricting the movement range of the moving plate 2 16, allowing it to slide only in a specific direction, thus improving the overall integrity and controllability of the structure. The external side of the instrument 18 is slidably connected to one side of the moving plate 2 16, facilitating fine-tuning of the instrument 18 to achieve optimal working condition. Limiting bolts 2 17 are threadedly connected to both sides of the bottom of the functional plate 1 12. The external threads of the limiting bolts 2 17 are connected to the inner wall of the top of the functional plate 2 13. By rotating the limiting bolts 2 17, the position of the functional plate 2 13 relative to the functional plate 1 12 can be precisely adjusted, thereby achieving indirect control of the positions of the moving plate 1 15 and the moving plate 2 16, facilitating flexible changes in the position and state of the instrument 18 according to actual conditions. The external thread of the stabilizing bolt 10 is connected to the inside of the limiting plate 8. After the limiting plate 8 is adjusted to a suitable angle, tightening the stabilizing bolt 10 can firmly fix it, preventing the angle from changing due to external force or operational vibration, and providing reliable angle protection for puncture operations.

[0027] Working principle: When using the medical ultrasound puncture frame, the limiting bolt 2 inside the top of the functional ring 1 rotates, and the bottom end of the limiting bolt 2 contacts the top end of the guide tube 3. The top end of the guide tube 3 has multiple holes. When the puncture needle is inside the guide tube 3, the limiting bolt 2 fixes its movement space to prevent loosening. At the same time, multiple fixing bolts 5 are threaded on the outside of the functional ring 6. The bottom end of the fixing bolt 5 is fixedly connected to the fixing pad 4. The bottom end of the fixing pad 4 contacts the outside of the guide tube 3. The fixing bolts 5 are used to adjust its movement space and restrict movement. When the angle of the guide tube 3 needs to be adjusted, the stabilizing bolt 10 rotates the support plate 7 to rotate at the top of the limiting plate 8. When the appropriate angle is adjusted, the stabilizing plates 9 on both sides of the limiting plate 8 are used to fix the support plate 7. At the same time, the stabilizing bolt 10 passes through the stabilizing plate 9 and the limiting plate 8. The stabilizing bolt 10 passes through and rotates to tighten the support plate 7, thereby solving the problem of unstable connection between the puncture needle of different sizes and the guide tube 3 when adjusting the angle.

[0028] When using a medical ultrasound puncture frame, the functional plate 12 slides inside the top of the functional plate 2 13. When the appropriate angle is reached, the limiting bolt 2 17 passes through the holes on both sides of the functional plate 12 and the top sides of the functional plate 2 13. The limiting bolt 2 17 is rotated to tighten and fix the device. When the instrument 18 is inside the functional plate 12 and the functional plate 2 13, the multiple fixing bolts 2 14 connected to the external threads of the functional plate 12 and the functional plate 2 13 push the moving plate 15 and the moving plate 2 16, so that the adjacent side of the moving plate 15 and the moving plate 2 16 is fixedly connected to the outside of the instrument 18, thereby stabilizing the instrument 18 and solving the problem of the probe size not matching the puncture frame size.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
