Detailed Implementation

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Reference Figure 1-6 This invention provides a musculoskeletal ultrasound probe-assisted fixation device, comprising:

[0029] The limiting part includes a base plate 1, a lifting device is provided on the top surface of the base plate 1, and a moving device is provided at the center of the top surface of the lifting device.

[0030] The fixing part includes a support frame 2, two support frames 2 are fixed to the top surface of the lifting device on both sides, and a first adjustment device is provided on each of the two support frames 2; the moving device can be translated along the axial direction of the two first adjustment devices; a second adjustment device is provided between the two first adjustment devices, a third adjustment device is provided on the second adjustment device, and a telescopic device for clamping the probe body 25 is provided at the bottom of the third adjustment device; the second adjustment device, the third adjustment device and the telescopic device are all located above the moving device.

[0031] In practice, medical staff often need to sit at the bedside to perform interventional treatments. However, because the interventional site needs to be constantly located, medical staff must constantly hold an ultrasound probe to probe the affected area for imaging observation. This necessitates frequent switching of surgical tools, significantly impacting work efficiency. The lifting device in this invention can be adjusted to accommodate both the patient's and medical staff's height, ensuring the medical staff are at the optimal height during surgery and improving comfort. Since different patients have different affected areas, a movable device allows for lateral movement of the patient. This design ensures the medical staff are always in the most comfortable position, enhancing adaptability and comfort by adjusting the patient's position during surgery. The first adjustment mechanism enables coarse adjustment, allowing the probe body 25 to be roughly adjusted around the patient's angle. A second adjustment device then enables fine adjustment, and a third adjustment device allows for directional adjustment in a direction different from the first and second devices, achieving omnidirectional adjustment. Finally, a telescopic device adjusts the vertical position of the probe body 25. Since the probe body 25 needs to exert pressure on the human body during detection, and this pressure must be maintained for a period of time to ensure stable and clear imaging, the first, second, and third adjustment devices, as well as the telescopic device, all function as positioning devices, maintaining the existing state and thus maintaining continuous pressure. This invention provides auxiliary fixation for the probe body 25, improving work efficiency.

[0032] Further optimization of the scheme: the first adjustment device includes a first motor 3, which is fixed to the top side of the support frame 2. The output end of the first motor 3 passes through the support frame 2 and is fixed to an adjustment gear 4. Limiting blocks 5 are fixed to both sides of the top surface of the moving device. Limiting holes are opened on the limiting blocks 5. The limiting holes are set with an arc-shaped structure. A ring 6 is provided through the limiting holes. The outer wall of the ring 6 slides in contact with the inner wall of the limiting hole. An arc-shaped sleeve 7 is fitted on the top outer wall of the ring 6. The arc-shaped sleeve 7 is fixed to the ring 6. The bottom surface of the arc-shaped sleeve 7 is provided with gear teeth, which mesh with the adjustment gear 4. The second adjustment device is set between the two arc-shaped sleeves 7.

[0033] The first motor 3 drives the adjusting gear 4 to rotate, and the ring 6 and the limiting block 5 achieve the limiting effect. The arc sleeve 7 drives the ring 6 to rotate, achieving coarse adjustment while driving the second adjusting device, the third adjusting device and the telescopic device to adjust the angle.

[0034] Further optimizing the scheme, the second adjustment device includes an adjustment shaft 8, with adjustment seats 9 rotatably connected to both ends of the adjustment shaft 8. The two adjustment seats 9 are fixedly connected to two arc-shaped sleeves 7. One end of the adjustment shaft 8 passes through one of the adjustment seats 9. A snap-fit ​​housing 10 is fixedly connected to the adjustment seat 9. A snap-fit ​​cylinder 11 is provided on the top and bottom surfaces of the snap-fit ​​housing 10. The protruding end of the adjustment shaft 8 is located inside the snap-fit ​​housing 10. A snap-fit ​​plate 12 is fixedly connected to the output end of the snap-fit ​​cylinder 11. The snap-fit ​​plate 12 is set as an arc-shaped structure. A snap-fit ​​rubber pad 13 is fixedly connected to the concave surface of the snap-fit ​​plate 12. The snap-fit ​​rubber pad 13 abuts against the adjustment shaft 8.

[0035] The adjustable shaft 8 can be rotated to further adjust the angle of the probe body 25. After the angle is positioned, the drive cylinder 11 pushes the locking rubber pad 13 to clamp the adjustable shaft 8 and achieve the angle positioning of the adjustable shaft 8.

[0036] Further optimizing the scheme, the third adjustment device includes a fixed seat 14, which is fixedly connected to the middle of the adjustment shaft 8. A fixed plate 15 is fixedly connected to the bottom surface of the fixed seat 14. Rotary seats 16 are fixedly connected to both sides of the bottom surface of the fixed plate 15. A rotating roller 17 is rotatably connected between the two rotating seats 16. The bottom of the rotating roller 17 is fixedly connected to the telescopic device. A positioning cylinder 18 is fixedly connected to both sides of the bottom surface of the fixed plate 15. A positioning rubber pad 19 is fixedly connected to the output end of the positioning cylinder 18. An arc-shaped groove is opened on the side of the positioning rubber pad 19, which is adapted to the rotating roller 17.

[0037] The rotation direction of the rotating roller 17 is perpendicular to the rotation direction of the first adjustment device and the second adjustment device, which together realizes universal adjustment. At the same time, the positioning rubber pad 19 can realize the positioning of the telescopic device.

[0038] The design is further optimized. The telescopic device includes a telescopic cylinder 20. The top surface of the telescopic cylinder 20 is fixedly connected to the rotating roller 17. A telescopic rod 21 is provided inside the telescopic cylinder 20. A rubber plug 22 is fixedly connected to one end of the telescopic rod 21. The rubber plug 22 slides in contact with the inner wall of the telescopic cylinder 20. The other end of the telescopic rod 21 passes through the bottom surface of the telescopic cylinder 20 and is fixedly connected to a clamping cylinder 23. A rubber layer 24 is provided inside the clamping cylinder 23. The rubber layer 24 is used to clamp the probe body 25. A positioning mechanism is provided in the inner cavity of the telescopic cylinder 20.

[0039] When adjusting the vertical direction of the probe body 25, medical staff can directly pull down the telescopic rod 21 to adjust the length. After reaching the designated position and pressure, the telescopic rod 21 can be released. Under the action of the positioning mechanism, the pressure and angle can remain unchanged, and continuous imaging can be maintained, which is convenient for medical staff to carry out the next step of interventional treatment.

[0040] The scheme is further optimized. The positioning mechanism includes an oil tank 26, which is fixed to one side of the bottom surface of the fixed plate 15. A first one-way valve 27 and a second one-way valve 28 are connected to the outer wall of the telescopic cylinder 20. The oil tank 26 is connected to the first one-way valve 27 through a first hose. A connecting component is connected to the bottom of the oil tank 26. The connecting component is connected to the second one-way valve 28 through a second hose.

[0041] When the telescopic rod 21 is pulled down, the oil in the oil tank 26 is drawn into the telescopic cylinder 20 through the first one-way valve 27. After the telescopic rod 21 is released, the connecting component prevents the oil from flowing back, thus fixing the position.

[0042] Further optimization of the scheme: the connecting component includes a connecting housing 29, which is fixed to the bottom surface of the oil tank 26. The top of the connecting housing 29 is connected to the oil tank 26. A connecting pipe 30 is connected to the bottom of the connecting housing 29. The connecting pipe 30 is connected to the second one-way valve 28 through a second flexible hose. A partition plate 31 is fixed to the top wall of the connecting pipe 30. The periphery of the partition plate 31 is fixed to the inner wall of the connecting housing 29. Several limiting pipes 32 are fixed at equal intervals around the bottom surface of the inner cavity of the connecting housing 29. An electromagnetic plate 33 is fixed to the bottom surface of the inner cavity of the limiting pipe 32. One end of a spring 34 is fixed to the top surface of the electromagnetic plate 33. The other end of the spring 34 is fixed to a limiting rod 35. The top of the limiting rod 35 penetrates the partition plate 31, and the outer wall of the limiting rod 35 slides in contact with the inner wall of the limiting pipe 32. A sealing plate 36 is fixed to the top surface of several limiting rods 35. A rubber sealing layer 37 is fixed to the bottom surface of the sealing plate 36.

[0043] When it is necessary to reset or move the telescopic rod 21, the electromagnetic plate 33 is energized to release the spring 34, realize the connection state of the connecting pipe 30, and the oil in the telescopic cylinder 20 returns to the oil tank 26, thus resetting the telescopic rod 21.

[0044] Further optimization of the scheme: the lifting device includes a top plate 38, and several lifting cylinders 39 are fixedly connected to both sides of the top surface of the top plate 38. The output end of the lifting cylinder 39 passes through the top plate 38 and is fixedly connected to the top surface of the bottom plate 1. A moving device is provided on the top surface of the top plate 38.

[0045] The lifting cylinder 39 drives the top plate 38 to rise and fall, which in turn drives the upper bed board 44 and the lower bed board 43 to rise and fall.

[0046] In a further optimized design, the mobile device has two base frames 40, which are fixed to the top surfaces of the top plate 38 on both sides. A moving screw 41 is rotatably connected between the two base frames 40. One end of the moving screw 41 passes through one of the base frames 40 and is fixed to the output end of the moving motor 42. The moving motor 42 is fixed to the side wall of the base frame 40. A displacement mechanism is threadedly connected to the moving screw 41.

[0047] The set mobile motor 42 drives the mobile screw 41 to rotate, which in turn drives the upper bed plate 44 to move laterally.

[0048] The scheme is further optimized. The displacement mechanism includes a lower bed plate 43, which is fixedly connected to two bottom frames 40. A strip hole is opened on the top surface of the lower bed plate 43. The top surface of the lower bed plate 43 slides in contact with an upper bed plate 44. Two displacement seats 45 are fixedly connected to the bottom surface of the upper bed plate 44. The two displacement seats 45 pass through the strip hole and are connected to the moving screw 41 by threads. The side wall of the displacement seat 45 slides in contact with the inner wall of the strip hole.
