Description

Technical Field

[0001] This utility model relates to the field of puncture fixation device technology, specifically a puncture fixation device. Background Technology

[0002] A puncture fixation device is a device used in pain management. A pain management puncture fixation device is an auxiliary device specifically designed for use in pain management treatment, aiming to provide stable support and precise puncture guidance to ensure the accuracy and safety of the treatment process.

[0003] Currently, most existing puncture fixation devices are primarily designed for vertical adjustment, adapting to different patient body shapes and treatment needs by adjusting height. However, their horizontal adjustment capability is relatively weak, limiting the precise selection and positioning of puncture points and making it difficult for doctors to achieve the optimal puncture angle and depth during operation. Furthermore, existing fixation devices are insufficiently adaptable to puncture needles of different sizes and specifications. Because puncture needles vary in diameter, length, and other parameters, while the clamping mechanism and adjustment range of existing fixation devices are often relatively fixed, the puncture needle is prone to shaking or shifting during installation and use. This instability not only affects the accuracy of punctures. Therefore, this invention provides a puncture fixation device. Utility Model Content

[0027] Please see Figure 1-5 ,

[0028] Example 1: A puncture fixation device includes a base 1, a fixing box 3, a needle tube adjusting sleeve 6 and a needle tube 7. The base 1 is used to provide a stable support platform to ensure the stability of the entire puncture fixation device.

[0029] The base 1 has a fixed concave surface 2 at the top, which is used to support the patient's body parts and ensure the accuracy of the puncture operation. The base 1 has fixed boxes 3 on both sides of the top, and each fixed box 3 has a slide 4 at the top. The slide 4 has a slide rod 5 at the top, which provides support for the slide rod and allows the slide rod to move in the vertical direction. The slide rod 5 on both sides is provided with a needle tube adjusting sleeve 6, which allows the needle tube adjusting sleeve to be adjusted in the vertical direction. The needle tube adjusting sleeve 6 is slidably connected to a needle sleeve 7, which is used to accommodate and protect the puncture needle.

[0030] In this embodiment, a fixed shaft 8 is provided at the connection between the slide rods 5 on both sides and the needle tube adjusting sleeve 6. The fixed shaft 8 is used to connect the slide rods and the needle tube adjusting sleeve to ensure a stable connection between them. A rotating shaft 9 is provided at one end of the connection between the fixed shaft 8 and the needle tube adjusting sleeve 6. The rotating shaft 9 is used to allow the needle tube adjusting sleeve to rotate around the fixed shaft at a certain angle, increasing the flexibility of the puncture angle. The fixed end of the rotating shaft 9 is connected to the needle tube adjusting sleeve 6.

[0031] In this embodiment, a first slide rail 10 is provided on the front and rear sides of the inner wall of the needle tube adjusting sleeve 6 facing the needle tube 7. The first slide rail 10 is used to guide the needle tube to slide in the horizontal direction. The needle tube 7 is slidably connected to the needle tube adjusting sleeve 6 through the first slide rail 10. A control handle 11 is provided on the top of the needle tube 7. The control handle 11 is used to manually control the sliding of the needle tube in the needle tube adjusting sleeve and the rotation of the needle tube adjusting sleeve.

[0032] In this embodiment, stabilizing sleeves 12 are provided on both sides of the bottom of the needle sheath 7. The stabilizing sleeves 12 are used to increase the stability of the needle sheath for the puncture needle. A moving plate 13 is provided at the end of the stabilizing sleeve 12 away from the needle sheath 7. The moving plate 13 is used to allow the stabilizing sleeve to slide on the slide rail plate. Control pins are provided at the connection between the moving plates 13 on both sides and the second slide rail 15, which are used to fix the moving plate 13 after the position is adjusted. A slide rail plate 14 is provided on the side of the bottom of the needle tube adjusting sleeve 6 facing the moving plate 13. The slide rail plate 14 is used to provide a sliding track for the moving plate. A second slide rail 15 is provided on the slide rail plate 14. The second slide rail 15 is used to guide the movement of the moving plate. The movement of the moving plate drives the stabilizing sleeve to move. The moving plates 13 on both sides are slidably connected to the slide rail plate 14 through the second slide rail 15.

[0033] It should be noted that when the puncture needle needs to be secured in the needle cannula 7, firstly, the puncture needle is inserted from the top of the needle cannula 7. As the puncture needle is inserted, it gradually contacts the arc-shaped stabilizing plates 18 located at the bottom of the needle cannula 7. These arc-shaped stabilizing plates 18 are connected to the stabilizing springs 16 via connecting rods 17. The stabilizing springs 16 are located inside the stabilizing sleeve 12 on the side facing the needle cannula 7. As the puncture needle is further inserted, it compresses the arc-shaped stabilizing plates 18 on both sides, causing them to open outwards. This action simultaneously compresses the stabilizing springs 16, making... The spring accumulates elastic potential energy. When the puncture needle reaches the predetermined depth, the elastic potential energy of the stabilizing spring 16 will push the connecting rod 17, thereby causing the arc-shaped stabilizing plate 18 to fit tightly against both sides of the puncture needle. At the same time, since the stabilizing sleeve 12 can be moved by the moving plate 13, the movement of the moving plate 13 is achieved by the second slide rail 15 moving on the slide rail plate 14. The movement of the stabilizing sleeve 12 can be finely adjusted horizontally according to the size of the puncture needle, ensuring that the puncture needle can be stably installed in the needle sleeve 7, thereby accommodating puncture needles of different sizes.

[0034] Example 2: It also includes a stabilizing spring 16 inside the stabilizing sleeve 12 facing the needle tube 7. The stabilizing spring 16 is used to provide a clamping force on the puncture needle. The other end of the stabilizing spring 16 is provided with a connecting rod 17, which is used to connect the stabilizing spring and the arc-shaped stabilizing plate to transmit the clamping force. The other end of the connecting rod 17 is provided with an arc-shaped stabilizing plate 18, which is used to contact the puncture needle and provide a stable clamping effect. Both arc-shaped stabilizing plates 18 are located on the bottom side inside the needle tube 7.

[0035] In this embodiment, both sides of the fixed box 3 are provided with a fixed soft plate 19 on the side facing the fixed concave surface 2. The fixed soft plate 19 is used to increase patient comfort. The side of the fixed soft plate 19 facing the inside of the fixed box 3 is provided with a connecting column 20. The connecting column 20 is used to connect the fixed soft plate and the adjusting plate and transmit the adjusting force. The other end of the connecting column 20 is provided with an adjusting plate 21. The front and rear sides of the bottom of the inner wall of the fixed box 3 are provided with a ratchet locking device 22 at the connection with the adjusting plate 21. The ratchet locking device 22 is used to lock the position of the adjusting plate to ensure stability. The other end of the adjusting plate 21 is provided with a pull ring 23. The pull ring 23 is used to facilitate manual operation of the position of the adjusting plate, thereby adjusting the position of the fixed soft plate 19. The pull ring 23 is located on the side of the fixed box 3 away from the fixed concave surface 2.

[0036] The beneficial effects of the above embodiments:

[0037] This puncture fixation device, through the design of the fixed concave surface 2 on the top of the base 1, provides a stable support platform for the puncture operation. The design of the slide 4 and slide rod 5 allows the needle tube adjusting sleeve 6 to move flexibly in the vertical direction. The sliding connection between the first slide rail 10 on the inner wall of the needle tube adjusting sleeve 6 and the needle tube 7 allows the needle tube 7 to move in the horizontal direction, thereby expanding the adjustment range of the puncture point. In addition, the design of the moving plate 13 driving the sliding of the slide rail plate 14 on the stabilizing sleeve 12 allows the stabilizing sleeve 12 to be finely adjusted in the horizontal direction according to the size of the puncture needle, ensuring that the puncture needle can be firmly installed in the needle tube 7. The stabilizing spring 16 inside the stabilizing sleeve 12 drives the connecting rod 17 at the other end and the arc-shaped stabilizing plate 18 to clamp the puncture needle, effectively preventing the deviation caused by external force during the puncture process.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
