Description

Technical Field

[0001] This invention relates to the field of puncture needle fixation devices, and in particular to a medical puncture needle fixation and adjustment device. Background Technology

[0002] In percutaneous puncture surgery guided by X-rays, CT scans, or other imaging techniques, the needle needs to be kept stable after insertion and may require fine adjustments. Existing technical solutions mainly include: Manual fixation: The surgeon holds and fixes the needle directly with their hand throughout the entire procedure. This is the most traditional method, and the surgeon's hand is exposed to the radiation field the entire time.

[0003] Simple clamping fixation: Using simple hemostatic forceps, special fixation clips, or tape, the needle is temporarily fixed to the patient's skin or bed sheet. This method can only achieve a simple "clamping" effect. Once adjustment is needed, the fixation must be removed and the needle must be manually repositioned. Fine adjustments while fixed are not possible.

[0004] Universal instrument fixation arms: Some operating rooms are equipped with large, multi-jointed universal robotic arms (such as snake arms) with universal clamps at their ends. While these devices can fix and adjust the position, they are usually bulky, cumbersome to operate, have relatively coarse positioning accuracy, and are not specifically designed for the rapid fixation and millimeter-level fine adjustment of puncture needles. They are also relatively expensive.

[0005] To address this issue, a medical puncture needle fixation and adjustment device is proposed. Summary of the Invention

[0020] 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.

[0021] 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.

[0022] Reference Figures 1-4 The present invention provides a medical puncture needle fixation and adjustment device, comprising: The bottom component includes a housing 1, a clamping mechanism is fixedly connected to the bottom of the housing 1, a lateral adjustment mechanism is provided inside the housing 1, an angle adjustment mechanism is provided on the lateral adjustment mechanism, and a height adjustment mechanism is provided on the angle adjustment mechanism. The fine-tuning component includes a lower plate 2 and an upper plate 3. A ball support 4 is fixedly connected to the lower plate 2. A ball 5 is rotatably connected inside the ball support 4. Positioning mechanisms are provided on both sides of the ball 5. The positioning mechanisms are fixedly connected to the lower plate 2. The upper plate 3 is fixedly connected to the ball 5. Several balance cylinders 6 are movably connected between the upper plate 3 and the lower plate 2. The puncture assembly includes a gripping rod 7, which is fixedly connected to the upper plate 3. A push-pull mechanism is provided on the gripping rod 7, and a puncture needle 8 is detachably connected to the push-pull mechanism. The controller 9 is fixedly connected to the housing 1. The horizontal adjustment mechanism, angle adjustment mechanism, height adjustment mechanism and positioning mechanism are all electrically connected to the controller 9.

[0023] In this device, the clamping mechanism is used to clamp onto other objects, such as an operating table, or other supporting objects, to facilitate surgical operations. The lateral adjustment mechanism is used to adjust the upper structure laterally. In practical applications, the angle adjustment mechanism can be adjusted laterally, and the angle adjustment mechanism can adjust the angle of the upper height adjustment mechanism. The height adjustment mechanism can adjust the height of the upper fine-tuning component and the puncture component. The fine-tuning component is used to make fine adjustments to the puncture needle 8. The positioning mechanism is opened by the controller 9, so that the ball 5 can rotate within the ball support 4. During adjustment, the gripping rod 7 is held so that the upper plate 3 can rotate, which in turn drives the ball 5 to rotate within the ball support 4, thereby making fine adjustments. When the fine adjustments are in place, the ball 5 is positioned by the positioning mechanism. The push-pull mechanism is manually operated to allow the puncture needle 8 to enter the surgeon's body.

[0024] The scheme is further optimized. The push-pull mechanism includes a fixed tube 10, which is fixedly connected to the holding rod 7. A push-pull column 11 is slidably arranged inside the fixed tube 10. A slot 12 is opened on the push-pull column 11. A puncture needle 8 is detachably connected to the slot 12. An installation cavity is opened inside the push-pull column 11. A first electric telescopic rod 13 is fixedly connected inside the installation cavity. A first top block 14 is fixedly connected to the output end of the first electric telescopic rod 13. The first top block 14 is slidably connected inside the installation cavity and abuts against the puncture needle 8. A third threaded hole is opened on the fixed tube 10. A first positioning stud 15 is threadedly connected inside the third threaded hole. The first electric telescopic rod 13 is electrically connected to the controller 9. A sliding groove 48 is opened on the push-pull column 11. A guide block 49 is fixedly connected inside the fixed tube 10 and is located in the sliding groove 48.

[0025] Before the operation, the puncture needle 8 is first placed into the slot 12. The shape of the slot 12 is adapted to the puncture needle 8. Then, the first electric telescopic rod 13 is activated. The first electric telescopic rod 13 extends so that the first top block 14 can press against the puncture needle 8. When the puncture is performed, the first positioning stud 15 is loosened so that the push-pull column 11 can move within the fixed tube 10. Pushing the push-pull column 11, the guide block 49 and the sliding groove 48 cooperate to prevent the push-pull column 11 from engaging.

[0026] The scheme is further optimized. The positioning mechanism includes several second electric telescopic rods 16. The output end of the second electric telescopic rod 16 is fixedly connected to a second top block 17. Several pointed cones 18 are fixedly connected to the second top block 17, with the pointed cones 18 facing the sphere 5. A base plate 19 is fixedly connected to the lower plate 2. The second electric telescopic rods 16 are fixedly connected to the base plate 19. A guide tube 20 is fixedly connected to the base plate 19. The second top block 17 is slidably disposed in the guide tube 20. The second electric telescopic rods 16 are electrically connected to the controller 9.

[0027] When it is necessary to position the ball 5, the second electric telescopic rod 16 is activated by the controller 9. The second electric telescopic rod 16 extends so that the cone 18 on the second top block 17 contacts the ball 5, thereby preventing the ball 5 from rotating. When it is necessary for the ball 5 to rotate, the cone 18 can be separated from the ball 5.

[0028] The scheme is further optimized. The lateral adjustment mechanism includes a first motor 21, which is fixedly connected inside the outer casing 1. Two guide rods 22 are fixedly connected inside the outer casing 1. The angle adjustment mechanism is slidably mounted on the guide rods 22. A first threaded rod 23 is fixedly connected to the drive shaft of the first motor 21. The end of the first threaded rod 23 away from the first motor 21 is rotatably connected inside the outer casing 1. A first fixing block 24 is fixedly connected to the angle adjustment mechanism. A first threaded hole is opened on the first fixing block 24. The first threaded rod 23 is threadedly connected to the first threaded hole. The first motor 21 is electrically connected to the controller 9.

[0029] The first motor 21 drives the first threaded rod 23 to rotate. When the first threaded rod 23 rotates, it can drive the first fixed block 24 to move, thereby allowing the angle adjustment mechanism to move laterally. The guide rod 22 facilitates the sliding of the angle structure.

[0030] The scheme is further optimized. The angle adjustment mechanism includes a movable box 25. Several second fixed blocks 26 are fixedly connected to the outside of the movable box 25. A first through hole is opened on the second fixed block 26. The guide rod 22 is slidably disposed in the first through hole. A rotating box 27 is rotatably connected inside the movable box 25. The rotating box 27 is rotatably connected inside the movable box 25 through a first rotating shaft 28. A first drive mechanism is disposed outside the movable box 25. The first drive mechanism is drivenly connected to the first rotating shaft 28. The first drive mechanism is electrically connected to the controller 9. The height adjustment mechanism is rotatably disposed inside the rotating box 27. A second drive mechanism is disposed inside the rotating box 27. The second drive mechanism is drivenly connected to the height adjustment mechanism.

[0031] When it is necessary to adjust the angle of the rotating box 27, the first rotating shaft 28 is driven by the first driving mechanism. When it is necessary to adjust the angle of the height adjustment mechanism, the height adjustment mechanism is driven by the second driving mechanism. The rotation direction of the rotating box 27 is different from the rotation direction of the height adjustment mechanism.

[0032] In a further optimized design, the first drive mechanism includes a second motor 29, which is fixedly connected inside the housing 1. A first gear 30 is fixedly connected to the drive shaft of the second motor 29, and a second gear 31 is fixedly connected to the first rotating shaft 28. The first gear 30 and the second gear 31 mesh, and the second motor 29 is electrically connected to the controller 9.

[0033] The second motor 29 drives the first gear 30 to rotate, and the first gear 30 drives the second gear 31 to rotate, thereby enabling the first rotating shaft 28 to rotate.

[0034] The design is further optimized. The height adjustment mechanism includes an upright column 32, which is rotatably connected to the rotating box 27 via a second rotating shaft 33. A second drive mechanism is connected to the upright column 32. A cavity 34 is provided inside the upright column 32. A motor housing 35 is fixedly connected to the top of the upright column 32. A third motor 36 is fixedly connected inside the motor housing 35. A second threaded rod 37 is fixedly connected to the drive shaft of the third motor 36. A lifting block 38 is slidably arranged inside the cavity 34. A second threaded hole is provided on the lifting block 38. The second threaded rod 37 is threaded into the second threaded hole. Two elongated holes 39 are provided on the upright column 32 and communicate with the cavity 34. A connecting block is fixedly connected to the lifting block 38. A support column 40 is fixedly connected to the connecting block. The support column 40 is fixedly connected to the lower plate 2. The third motor 36 is electrically connected to the controller 9.

[0035] When height adjustment is required, the third motor 36 drives the second threaded rod 37 to rotate. When the second threaded rod 37 rotates, it drives the lifting block 38 to move. The lifting block 38 drives the connecting block and the support column 40 to rise and fall, thereby driving the lower plate 2 to rise and fall. The second rotating shaft 33 causes the upright column 32 to rotate and connect to the rotating box 27.

[0036] In a further optimized design, a semi-circular gear 41 is fixedly connected to the bottom surface of the upright column 32. The second drive mechanism includes a fourth motor 42, which is fixedly connected inside the rotating box 27. A third gear 43 is fixedly connected to the drive shaft of the fourth motor 42, and the third gear 43 meshes with the semi-circular gear 41.

[0037] When the angle of the upright column 32 needs to be adjusted, the third gear 43 is driven by the fourth motor 42, and the third gear 43 drives the semi-circular gear 41 to move, so that the upright column 32 can rotate.

[0038] The scheme is further optimized. The clamping mechanism includes a U-shaped plate 44. Several fourth threaded holes are opened on the U-shaped plate 44. A second positioning stud 45 is threadedly connected to the fourth threaded hole. A pressure plate 47 is rotatably connected to the second positioning stud 45. The pressure plate 47 is located inside the U-shaped plate 44.

[0039] When it is necessary to clamp this device, put the U-shaped plate 44 on the fixed object, and then rotate the second positioning stud 45 to make the pressure plate 47 clamp the object.

[0040] The scheme is further optimized by fixing a flexible protective cover 46 between the lower plate 2 and the upper plate 3, and the balance cylinder 6 is movably connected to the upper plate 3 and the lower plate 2 respectively through universal joints.

[0041] The flexible shield 46 can protect the internal structure.

[0042] The method of using this device is as follows: Before surgery, the puncture needle 8 is first placed into the slot 12, the shape of which is adapted to the puncture needle 8. Then, the first electric telescopic rod 13 is activated, extending so that the first top block 14 can rest on the puncture needle 8. When clamping the device, the U-shaped plate 44 is placed on the fixed object, and then the second positioning stud 45 is rotated to clamp the object with the pressure plate 47. The lateral adjustment mechanism is operated by activating the first motor 21, which drives the first threaded rod 23 to rotate. When the first threaded rod 23 rotates, it can move the first fixed block 24, thereby allowing the angle adjustment mechanism to move laterally. When it is necessary to adjust the angle of the rotating box 27, the second motor 29 drives the first gear 30 to rotate, which in turn drives the second gear 31 to rotate, causing the first rotating shaft 28 to rotate, thereby allowing the rotating box 27 to move laterally. The rotating box 27 rotates. When the angle of the upright column 32 needs to be adjusted, the third gear 43 is driven by the fourth motor 42, and the third gear 43 drives the semi-circular gear 41 to move, so that the upright column 32 can rotate. When the height needs to be adjusted, the third motor 36 drives the second threaded rod 37 to rotate. When the second threaded rod 37 rotates, it drives the lifting block 38 to move. The lifting block 38 drives the connecting block and the support column 40 to rise and fall, thereby driving the lower plate 2 to rise and fall. When fine-tuning, hold the holding rod 7 so that the upper plate 3 can rotate, and at the same time drive the ball 5 to rotate in the ball support 4, so as to perform fine-tuning. When the fine-tuning is in place, the ball 5 is positioned by the positioning mechanism. When performing the puncture, the first positioning stud 15 is loosened so that the push-pull column 11 can move in the fixed tube 10. Pushing the push-pull column 11 allows the puncture needle 8 to enter the surgeon's body.
