[0026] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with examples. The examples are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0027] Thyroid puncture is a common clinical examination and treatment procedure, mainly used to diagnose thyroid diseases, such as benign and malignant determination of thyroid nodules, thyroid function tests, etc. Traditional thyroid puncture technology usually obtains thyroid tissue samples through fine needle aspiration (FNA). During the operation, the accuracy of the puncture needle, the comfort and stability of the patient are the keys to success. However, due to the complex anatomical structure of the patient's neck and the strict requirements on the depth and angle of the puncture needle during the operation, there are often certain shortcomings and deficiencies in the existing technology.

[0028] Traditional thyroid puncture devices mostly rely on manual operation to position and advance the puncture needle, which requires a high level of technical skills from the operator and is easily affected by changes in the patient's body position and posture. The patient needs to remain still for a long time during the puncture, which can cause neck fatigue or discomfort, affecting the stability and accuracy of the puncture. In addition, existing puncture devices often do not fully consider the patient's comfort and stability, which may cause excessive twisting or displacement of the neck, affecting the accuracy of the puncture process.

[0029] Therefore, according to Figure 1-Figure 7 As shown, this embodiment proposes a thyroid puncture device, including a base 1 and a puncture needle 10. When in use, the base 1 is fixed on a corresponding operating table, and a neck support seat 2 is installed on the base 1. The neck support seat 2 is ergonomically designed and can provide uniform support force, thereby providing stable support force for the patient's neck. Furthermore, elastic baffles 3 are installed on both sides of the neck support seat 2. The elastic baffles 3 are made of medical silicone, and the elastic baffles 3 are connected to the base 1 through a telescopic assembly. Accordingly, two groups of elastic baffles 3 are located on both sides of the patient's neck and provide side support force. At the same time, the telescopic assembly includes an electric push rod 21, the lower end of the electric push rod 21 is hinged to the base 1, and the telescopic end of the electric push rod 21 is hinged to the elastic stop pad 3. The electric push rod 21 is tilted. Since the support force of the elastic stop pad 3 is relatively low, after the patient's neck is located inside it, the electric push rod 21 is started, and its telescopic end is hinged to the upper end of the elastic stop pad 3, thereby enabling the elastic stop pad 3 to be in close contact with the patient's neck and provide sufficient support force, thereby avoiding the generation of a sense of oppression and providing side support force to ensure that during the puncture process, the patient's neck will not be excessively twisted or displaced. This design can effectively fix the patient's head and reduce the sense of oppression on the neck through the softness of the elastic stop pad 3.

[0030] An inner neck ring 4 is provided above the base 1, and an airbag belt 5 is installed on the inner side of the inner neck ring 4, a silicone layer is provided on the outer side of the airbag belt 5, and connection ports 22 are provided at both ends of the airbag belt 5. When in use, the airbag belt 5 is inflated by an external device, and the air pressure of the airbag is adjusted by inflation or exhaust to ensure its fixing effect on the patient's neck. Accordingly, the purpose of the airbag belt 5 is to be able to apply pressure evenly, avoid compressing local areas, and improve the comfort of the patient.

[0031] An extension frame 6 is installed at both ends of the inner neck ring 4. The cross section of the extension frame 6 is L-shaped, and the extension frame 6 is connected to the base 1 through a connecting assembly to maintain the stability of the structure and ensure accurate positioning during the puncture process. The connecting assembly includes two groups of symmetrically arranged protruding structures 11. The protruding structure 11 is formed integrally with the base 1, and a socket 12 is provided on the inner side of the protruding structure 11. The upper and lower ends of the socket 12 are connected to the outside world. The socket 12 can accommodate the extension frame 6 to pass through and is fixed by a locking member 13. The design of the socket 12 allows the extension frame 6 to pass freely. At the same time, the locking member 13 can firmly fix the extension frame 6 in a predetermined position to ensure that the entire device will not be displaced. Accordingly, a plurality of locking members 13 are provided. In this embodiment, two groups of locking members 13 are correspondingly provided on each protruding structure 11, and the locking member 13 is connected to the protruding structure 11 through a thread. The extension frame 6 is provided with a limiting groove 14, and the limiting groove 14 is provided with several groups. In this embodiment, each group of the extension frame 6 is provided with four groups of limiting grooves 14. Correspondingly, the inner side of the socket 12 is provided with an insertion strip 15, and the number and position of the insertion strip 15 correspond to the limiting groove 14, that is, the socket 12 is also provided with four groups of insertion strips 15, and the insertion strips 15 are located in the limiting groove 14. Through the cooperation of the insertion strips 15 and the limiting groove 14, it is ensured that the extension frame 6 can only move up and down, so as to facilitate the precise adjustment of the position. The extension frame 6 is provided with a through hole 16, and the through hole 16 can accommodate the locking member 13 to pass through. There are multiple groups of through holes 16 from top to bottom, and the position of the through hole 16 corresponds to the position of the locking member 13. Through the design of multiple through holes 16, the height of the extension frame 6 can be adjusted as needed, thereby adjusting the position of the inner neck ring 4.

[0032] Two groups of outer neck rings 7 are arranged symmetrically in front and back on the outside of the inner neck ring 4, and the outer neck rings 7 are fixedly connected to the extension frame 6. The outer neck rings 7 adopt a front and back symmetrical design, which can provide uniform support force and ensure the stability of the subsequent needle drive seat 9. An opening 8 is provided on the inner neck ring 4, and a needle drive seat 9 is installed on the inner side of the opening 8, and a puncture needle 10 is installed in the needle drive seat 9. In this embodiment, the opening 8 can accommodate the needle drive seat 9 to adjust the puncture angle. An electric linear module 23 is installed on the inner side of the needle drive seat 9, and the output end of the electric linear module 23 is connected to the puncture needle 10 through a fixed block 24. A joint 25 is installed on the upper end of the puncture needle 10, and the joint 25 is an interface that can be connected to an external pipeline. Thus, the puncture needle 10 is installed in the needle drive seat 9 and driven by the electric linear module 23. This design ensures that the puncture needle 10 can be accurately advanced and withdrawn when needed, while avoiding unnecessary misoperation. The corresponding electric linear module 23 can provide a stable propulsion force and reduce the fatigue of the doctor's manual operation.

[0033] The needle drive seat 9 is connected to the outer neck ring 7 through an adjustment component. The outer neck ring 7 is provided with an arc-shaped limit opening 17. The adjustment component includes an extension column 18. One end of the extension column 18 is connected to the needle drive seat 9. The other end of the extension column 18 passes through the arc-shaped limit opening 17 and is threadedly installed with a locking ring 19. The diameter of the extension column 18 is adapted to the diameter of the arc-shaped limit opening 17. The locking ring 19 contacts the outer neck ring 7. Two groups of symmetrically arranged arc-shaped slide rails 20 are installed in the inner neck ring 4. The arc-shaped slide rails 20 are connected to the needle drive seat 9 through a slider. Specifically, the locking ring 19 is threadedly installed on the extension column 18 and contacts the outer neck ring 7. When the angle of the needle drive seat 9 is adjusted, the rotation of the locking ring 19 can fix the extension column 18 in a predetermined position, thereby preventing the puncture needle 10 from changing or deviating in angle during operation. The clamping force provided by the locking ring 19 ensures the stability of the extension column 18 after adjustment, and provides reliable support for the puncture operation. The locking ring 19 can be tightened and adjusted to fix the extension column 18 at the desired position to avoid changes in the angle of the puncture needle 10. During operation, the doctor can easily loosen the locking ring 19 and pull the locking ring 19 to cause the extension column 18 to move in the arc-shaped limit opening 17, thereby adjusting the angle of the needle drive seat 9. The design of the arc-shaped limit opening 17 allows the extension column 18 to slide within a certain range to adjust the angle of the needle drive seat 9. This design ensures that the puncture needle 10 can be accurately advanced along a predetermined angle through the cooperation of the arc-shaped track. During this process, the cooperation of the arc-shaped slide rail 20 and the slider ensures that the needle drive seat 9 moves along the correct track, thereby maintaining the stability and accuracy of the puncture needle 10, and then fixes it again by rotating the locking ring 19. Therefore, during the operation, the doctor can adjust the angle of the extension column 18 according to the patient's needs by loosening the locking ring 19 and pulling the locking ring 19. This process is simple and intuitive, and the angle of the puncture needle 10 can be quickly adjusted to position it more accurately. In this embodiment, the locking ring 19 adopts an anti-loosening design and is provided with a locking pin to ensure that the locking ring 19 will not loosen automatically after being tightened.
