Abstract
Description
Technical Field
[0001] This utility model relates to the field of microwave ablation needle technology, specifically to an anti-loosening transmission cable and a microwave ablation needle having the same. Background Technology
[0002] Microwave ablation therapy is a highly effective and safe tumor treatment technique. Its principle involves using a microwave antenna to radiate electromagnetic waves, causing charged ions and polar water molecules within biological tissue to rotate at high speed. This molecular motion converts microwave energy into heat energy through friction, causing the target tissue to reach a high temperature of 60-100°C within a short period. Under these temperature conditions, tumor cells rapidly undergo protein denaturation, coagulative necrosis, and dehydration, thereby achieving precise inactivation of the lesion.
[0003] Currently, most microwave ablation needles on the market are connected to the transmission cable via a straight-insertion circular electrical connector. The advantage is that it is easy to plug in and can be quickly plugged in and out, but the disadvantage is also obvious: it is easy to loosen under external force, which makes the connection unstable.

[0021] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0022] Example
[0023] The present invention will now be further described with reference to the accompanying drawings.
[0024] like Figure 1 As shown, this embodiment provides an anti-loosening transmission cable, including a cable body 1, and further including:
[0025] Connector 10 is installed at one end of the cable body 1;
[0026] The elastic buckle 12 is provided on the connector 10 to prevent the connector 10 from falling off the connector seat 11.
[0027] The working principle and beneficial effects of the above technical solution are as follows:
[0028] This utility model discloses an anti-loosening transmission cable. When the elastic clip 12 is manually pressed (using the thumb), it moves towards the connector 10 in the opposite direction, inserting the connector 10 into the connector base 11. After releasing the elastic clip 12, it remains locked in the connector base 11. To remove the connector 10, simply press the elastic clip 12 again, and the connector 10 will easily detach from the connector base 10. This utility model provides an anti-loosening transmission cable that uses the elastic clip 12 to securely connect the connector 10 and the connector base 11, preventing loosening even under external pulling and ensuring a stable connection.
[0029] In one embodiment, the elastic buckle 12 includes a fixing part 13, a snap-fit part 14, and an elastic part 15. The fixing part 13 is mounted on the connector 10. The snap-fit part 14 is protruding and transitionally connected between the fixing part 13 and the elastic part 15. The elastic part 15 is inclined upwards and its width is smaller than that of the snap-fit part 14.
[0030] The working principle and beneficial effects of the above technical solution are as follows:
[0031] The fixing part 13 is fixedly connected to the connector 10. The snap-fit part 14 is used to realize the fixing function in the connector seat 11, and the elastic part 15 is used to perform the snap-fit action of the snap-fit part 14. The elastic part 15 is tilted upward when no external force is applied. If the elastic part 15 is pressed manually, it will drive the snap-fit part 14 to move on the fixing part 13.
[0032] In one embodiment, a pressing part 16 is provided at the end of the elastic part 15 away from the snap-fit part 14, and the pressing part 16 is perpendicular to the elastic part 15.
[0033] The beneficial effects of the above technical solution are as follows:
[0034] The pressing part 17 is provided to facilitate manual pressing of the elastic part 15.
[0035] In one embodiment, the resilient snap 12 is made of deformable engineering plastic.
[0036] The beneficial effects of the above technical solution are as follows:
[0037] Highly elastic engineering plastics are selected to take advantage of their excellent elastic deformation characteristics.
[0038] In one embodiment, the back side of the elastic portion 15 is disposed near the connector 10, and the pressing portion 16 is exposed near the end of the connector 10 to abut against the connector 10.
[0039] The beneficial effects of the above technical solution are as follows:
[0040] The pressing part 16 protrudes from the back of the elastic part 15 near the end of the connector 10, so that after the pressing part 16 abuts against the connector 10, it is convenient to insert the connector 10 into the connector seat 11.
[0041] In one embodiment, a deformation groove 21 is provided on the front side of the elastic part 15 near the end of the pressing part 16.
[0042] like Figures 2 to 5 As shown, this embodiment also provides a microwave ablation needle, including: a needle bar 17 and a handle 18. The handle 18 is connected to the transmission cable as described above. The handle 18 is equipped with a connector seat 11 in conjunction with the connector 10. The connector seat 11 has a slot 19. The slot 19 has a convex shape for the connector 10 and the fixing part 13 to be inserted. The slot 19 has sub-clamping blocks 20 for limiting the locking part 14 symmetrically installed at the slot 19.
[0043] The working principle and beneficial effects of the above technical solution are as follows:
[0044] Holding the handle 18 with one hand and pressing the pressing part 16 with the thumb of the other hand, the elastic part 15 moves in the opposite direction towards the connector 10, inserting the connector 10 and the snap-fit part 14 connected to the fixing part 13 into the slot 19. After releasing the pressing part 16, the elastic part 15 drives the snap-fit part 14 to return to its original position. The width of the elastic part 15 is smaller than that of the snap-fit part 14, so that the snap-fit part 14 can be locked onto the sub-snap block 20, thus achieving a fixed connection between the connector 10 and the connector seat 11. If it is necessary to remove the connector 10, simply press the pressing part 16 again, and the snap-fit part 14 will retract from the sub-snap block 20, allowing the connector 10 to easily detach from the connector seat 10.
[0045] like Figure 6As shown, in one embodiment, a guide groove 24 is provided on the elastic part 15, and a guide rod 23 is slidably installed in the guide groove 24. One end of the guide rod 23 is slidably installed on the connector 10, and a wedge-shaped sliding block 22 is installed on the other end of the guide rod 23. The wedge-shaped sliding block 22 is slidably connected to the front side of the elastic part 15, and an impact block is installed on the wedge-shaped sliding block 22. A metal patch adapted to the impact block is installed on the connector seat 11.
[0046] The working principle and beneficial effects of the above technical solution are as follows:
[0047] After the pressing part 16 is released, the elastic part 15 drives the locking part 14 to reset. Simultaneously, the locking part 14 locks onto the sub-locking block 20. The front surface of the elastic part 15 drives the wedge-shaped sliding block 22 and the guide rod 23 connected to the wedge-shaped sliding block 22 to slide along the guide groove 24. The impact block on the wedge-shaped sliding block 22 quickly slides towards the connector seat 11 and impacts the connector seat 11, producing a sound to indicate that the connector 10 has been fixedly connected to the connector seat 11. When the pressing part 16 is pressed again, and the locking part 14 exits the sub-locking block 20, because the wedge-shaped sliding block 22 loses the constraint of the front surface of the elastic part 15, the guide rod 23 drives the wedge-shaped sliding block 22 to automatically slide down along the guide groove 24. The elastic buckle 12 is made of highly elastic engineering plastic, which can quickly reset after deformation, thus realizing the rapid movement of the wedge-shaped sliding block 22 and the sound produced by the impact block.
[0048] Specifically, a movable groove is provided on the connector 10, and one end of the guide rod 23 is slidably connected in the movable groove, thereby facilitating the limiting of the sliding of the guide rod 23.
[0049] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
