Description

Technical Field

[0001] This utility model relates to the technical field of ablation needles, and in particular to an ablation needle that is easy to position. Background Technology

[0002] Ablation needles are mainly used for tumor treatment. When using them, the ablation needle needs to be precisely inserted into the tumor. The traditional method of use requires manually inserting the ablation needle into the human body. The drawback of this method is that human operation has a large margin of error and it is easy to insert the wrong needle. The current ablation needles are first located by a positioning device before operation.

[0003] For example, patent application CN202323078434.7 discloses a microwave ablation needle positioning device. This patent pre-connects the microwave ablation needle 2 to the medical system. The positioning mechanism 3 adopts a double-end clamping structure, which can position and clamp the microwave ablation needle 2 at a certain position and adjust the height of the microwave ablation needle 2, thus positioning and clamping it above the patient's body for easy insertion. The displacement mechanism 4 supports the microwave ablation needle 2 and the positioning mechanism 3, facilitating adjustment of the overall position of the microwave ablation needle 2 and the positioning mechanism 3 to adapt to the insertion position of the microwave ablation needle 2. When using this microwave ablation needle positioning device, the patient first lies on the bed frame 1. The doctor moves the positions of the first slider 402 and the second slider 406, thereby moving the positioning mechanism 3 to the position where the microwave ablation needle 2 is to be inserted. Then, the positioning mechanism 3 is activated to clamp and adjust the position of the microwave ablation needle 2, placing the microwave ablation needle 2 on the first rubber pad. Between the first rubber pad 311 and the second rubber pad 322, under the elastic force of the first clamping spring 309 and the second clamping spring 320, the microwave ablation needle 2 can be stably clamped between the first rubber pad 311 and the second rubber pad 322. If it is necessary to adjust the height of the microwave ablation needle 2, the first adjusting screw 303 can be rotated down to press down the first mounting plate 308, and the second adjusting screw 314 can be rotated down to press down the second mounting plate 319, thereby causing the overall height of the first rubber pad 311 and the second rubber pad 322 to move down, thereby causing the microwave ablation needle 2 between the first rubber pad 311 and the second rubber pad 322 to move down. Conversely, rotating the first adjusting screw 303 and the second adjusting screw 314 upwards can cause the microwave ablation needle 2 between the first rubber pad 311 and the second rubber pad 322 to move up, thereby achieving the height adjustment effect of the microwave ablation needle 2. After completing the above positioning and adjustment operations, the treatment operation can be performed through the microwave ablation needle 2.

[0004] In the existing technology, the ablation needle can only be inserted vertically during use. This insertion direction is relatively limited. In actual use, the affected areas of patients vary, so the existing ablation needle positioning method is not flexible. Utility Model Content

[0013] A positioning tube passes through the universal ball and is fixedly connected to it. A fourth threaded rod is provided on the positioning tube.

[0014] Preferably, the bottom of the slide groove has a threaded hole that passes through the positioning post, and a second threaded rod that is threadedly connected to the threaded hole is inside the threaded hole.

[0020] Figure 1 This is a schematic diagram of an ablation needle for easy positioning according to the present invention.

[0021] Figure 2 This is a cross-sectional view of the positioning column of this utility model.

[0022] The components include: positioning plate 10, positioning hole 20, moving plate 30, support plate 31, guide rod 32, first scale gauge 33, first threaded rod 34, positioning column 40, sliding groove 41, threaded hole 42, second threaded rod 50, sliding column 60, second scale gauge 61, universal ball 70, universal ball seat 71, third threaded rod 72, positioning tube 80, and fourth threaded rod 81. Detailed Implementation

[0023] The embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0024] like Figure 1-2 In this first embodiment, an ablation needle for easy positioning includes...

[0025] Positioning plate 10, with positioning holes 20 at both ends;

[0026] The movable plate 30 is movably mounted on the positioning plate 10;

[0027] The positioning post 40 is fixedly connected to the movable plate 30, and one side of the positioning post 40 has a sliding groove 41;

[0028] The sliding column 60 has one end that can be moved and slide into the sliding groove 41;

[0029] The universal ball joint 71 is fixedly connected to the other end of the sliding column 60;

[0030] The universal ball 70 is disposed on the universal ball seat 71 and passes through the universal ball seat 71. The universal ball seat 71 has a third threaded rod 72 for fixing the universal ball 70.

[0031] The positioning tube 80 passes through the universal ball 70 and is fixedly connected to the universal ball 70. The positioning tube 80 is provided with a fourth threaded rod 81.

[0032] This embodiment is implemented as follows:

[0033] In use, this application first uses a strap through the positioning hole 20 to bind the device to the body, positioning the positioning plate 10 near the tumor. Then, the moving plate 30 is adjusted, causing the positioning column 40 to move. The sliding column 60 moves within the sliding groove 41, moving the universal ball seat 71 to adjust its position, bringing it closer to the tumor. The ablation needle is then passed through the positioning tube 80, and the universal ball 70 is rotated to align it with the tumor. The universal ball 70 is then fixed by the third threaded rod 72. The ablation needle is then inserted into the tumor, and finally, the ablation needle is fixed within the positioning tube 80 by the fourth threaded rod 81. This achieves the positioning of the ablation needle.

[0034] The advantage of this application compared to the prior art is that the direction of the ablation needle is flexibly adjustable and has a wide range of applications.

[0035] Please see Figure 1 , 2 The bottom of the slide groove 41 has a threaded hole 42 that passes through the positioning post 40. The threaded hole 42 has a second threaded rod 50 that is threadedly connected to the threaded hole 42. One end of the second threaded rod 50 that extends into the slide groove 41 is rotatably connected to the slide post 60. Both the slide post 60 and the slide groove 41 are polygonal prisms.

[0036] The rotation of the second threaded rod 50 allows it to move within the threaded hole 42, thereby pushing the slide bar 60 to move within the slide groove 41.

[0037] Please see Figure 1 The slide bar 60 has a second scale 61 distributed along the slide bar 60.

[0038] The operator can easily determine the distance the slide column 60 has moved by using the second scale 61 on the slide column 60.

[0039] Please see Figure 1 The positioning plate 10 is provided with two parallel support plates 31. Between the two support plates 31, there are several guide rods 32 and a first threaded rod 34 that is rotatably set. The guide rods 32 slide through the moving plate 30, and the first threaded rod 34 passes through the moving plate 30 and is threadedly connected to the moving plate 30.

[0040] The rotation of the first threaded rod 34 can drive the movable plate 30 to move along the guide rod 32.

[0041] Please see Figure 1 The guide rod 32 has a first scale 33 distributed along the guide rod 32.

[0042] The first scale 33 on the guide rod 32 allows the operator to easily observe the movement position of the moving plate 30 on the guide rod 32.

[0043] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
