Description

Technical Field

[0001] This utility model relates to the field of thyroid ultrasound technology, specifically a teaching aid for thyroid nodule ultrasound ablation simulation. Background Technology

[0002] The thyroid gland is the largest endocrine gland in the human body. Thyroid hormones promote metabolism and growth, playing a vital role in maintaining normal physiological functions. Thyroid nodules are a common condition, including both benign and malignant nodules, some of which require treatment. Ultrasound-guided ablation, as a minimally invasive technique, is increasingly being used for interventional treatment of thyroid nodules. Ablation is a restricted procedure, therefore doctors require extensive learning and training before performing actual ablation operations. This necessitates the use of thyroid nodule ultrasound ablation simulation teaching aids, such as the Chinese patent application CN202410996031.0, filed on 2024-07-24, which provides a thyroid nodule ultrasound ablation simulation teaching aid. This simulation teaching aid is simple in structure, easy to store, and less expensive than using a live subject, thus meeting the needs of practice.

[0003] After the thyroid nodule ultrasound ablation simulation teaching aid is used, it needs to be stored away to avoid being affected by the external environment. However, the device in the above-mentioned application does not have the function of being quickly stored and protected during use, which accelerates the aging and damage of the thyroid nodule ultrasound ablation simulation teaching aid and may lead to a decrease in simulation effect. Therefore, we propose a thyroid nodule ultrasound ablation simulation teaching aid to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this invention is to provide a thyroid nodule ultrasound ablation simulation teaching aid to solve the problem mentioned in the background art that the thyroid nodule ultrasound ablation simulation teaching aid does not have the function of being quickly stored and protected during use, which accelerates the aging of the thyroid nodule ultrasound ablation simulation teaching aid and leads to a decline in simulation effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a thyroid nodule ultrasound ablation simulation teaching aid, comprising a protective box, a cover plate movably connected to the upper surface of the protective box, a connecting shaft rotatably arranged inside the protective box, a fixing plate fixedly connected to the surface of the connecting shaft, and a thyroid teaching aid adhered to the surface of the fixing plate, a connecting plate fixedly connected to the inner wall of the protective box, the connecting shaft penetrating through the interior of the connecting plate, a limiting plate fixedly connected to the surface of the connecting shaft, and the surface of the limiting plate fitting against the outer wall of the protective box, a long pin slidably arranged inside the protective box, the end of the long pin located outside the protective box, and a handle fixedly connected to the end of the long pin.

[0006] Preferably, the connecting shaft and the connecting plate are rotatably connected, and a torsion spring that plays an elastic restoring role is fixedly connected to the surface of the connecting shaft, and the other side of the torsion spring is fixedly connected to the inner wall of the connecting plate.

[0007] Preferably, the torsion spring is initially in a stretched state, and a positioning rod is fixedly connected to the inner wall of the protective box.

[0008] Preferably, the surface of the fixing plate is provided with a slot corresponding to the long pin.

[0009] Preferably, a connecting spring that provides elastic reset is fixedly connected to the surface of the handle, and the other side of the connecting spring is fixedly connected to the outer wall of the protective box.

[0010] Preferably, a side plate is fixedly connected to the surface of the cover plate, and the side plates are symmetrically distributed about the center of the cover plate, and a first magnet is fixedly connected to the inner wall of the side plate.

[0011] Preferably, a second magnet is fixedly connected to the outer wall of the protective box, and the magnetic poles of the second magnet are opposite to those of the first magnet at adjacent positions.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This thyroid nodule ultrasound ablation simulation teaching aid adopts a novel structural design, the specific details of which are as follows: (1) The thyroid nodule ultrasound ablation simulation teaching aid is initially located inside the protective box. When the thyroid teaching aid is needed, the cover is opened first, and then the handle is pulled to move the end of the long pin out of the slot. At this time, the connecting shaft, the fixing plate and the thyroid teaching aid rotate under the action of the torsion spring. Finally, the connecting shaft, the fixing plate and the thyroid teaching aid rotate out of the protective box, making it easy to use. The operation process is simple and the work efficiency is high.

[0013] Furthermore, when the thyroid manipulative is inside the protective box, the torsion spring is stretched, and only after the end of the long pin moves out of the slot will the connecting shaft, the fixing plate, and the thyroid manipulative rotate clockwise.

[0014] (2) After using the thyroid nodule ultrasound ablation simulation teaching aid, the thyroid teaching aid needs to be put away again. At this time, the thyroid teaching aid can be rotated counterclockwise, and the fixing plate will rotate counterclockwise in sync. When the slot rotates to the same horizontal direction as the long pin, the long pin will return to its original position under the action of the handle and the connecting spring, that is, the long pin will enter the slot. At this time, the fixing plate will be in a locked state with the protective box again through the long pin. At this time, the thyroid teaching aid is put into the protective box, so that the thyroid teaching aid is not contaminated by dust.

[0015] Furthermore, after the thyroid teaching aid is placed inside the protective box, the cover can be closed. At this time, under the action of the first and second magnets, the side plate drives the cover to connect stably with the protective box. The operation process is quick and convenient, and the protection is good.

[0016] (3) In the process of releasing and rotating the thyroid nodule ultrasound ablation simulation teaching tool, the positioning rod plays a positioning role, so that the thyroid teaching tool, the connecting shaft and the fixing plate will not rotate excessively, thus ensuring stability.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1: The torsion spring 10, connecting shaft 2, and fixing plate 3 allow the connecting shaft 2 to rotate within the connecting plate 9, thus enabling the thyroid-shaped teaching aid 4 to be used quickly. Figures 1-6As shown, the device includes a protective box 1, a cover plate 13 movably connected to the upper surface of the protective box 1, a connecting shaft 2 rotatably arranged inside the protective box 1, a fixing plate 3 fixedly connected to the surface of the connecting shaft 2, and a thyroid-shaped teaching aid 4 adhesively connected to the surface of the fixing plate 3. A connecting plate 9 is fixedly connected to the inner wall of the protective box 1, and the connecting shaft 2 is penetrated through the interior of the connecting plate 9. A limiting plate 12 is fixedly connected to the surface of the connecting shaft 2, and the surface of the limiting plate 12 is in contact with the outer wall of the protective box 1. A long pin 5 is slidably arranged inside the protective box 1, and the end of the long pin 5 is located on the outside of the protective box 1. A handle 6 is fixedly connected to the end of the long pin 5.

[0021] The connecting shaft 2 and the connecting plate 9 are rotatably connected, and a torsion spring 10 with elastic reset function is fixedly connected to the surface of the connecting shaft 2. The other side of the torsion spring 10 is fixedly connected to the inner wall of the connecting plate 9. The torsion spring 10 is initially in a stretched state. A positioning rod 11 is fixedly connected to the inner wall of the protective box 1. A slot 8 corresponding to the long pin 5 is opened on the surface of the fixing plate 3. A connecting spring 7 with elastic reset function is fixedly connected to the surface of the handle 6, and the other side of the connecting spring 7 is fixedly connected to the outer wall of the protective box 1.

[0022] Initially, the thyroid manipulative 4 is inside the protective box 1, with the end of the long pin 5 inside the slot 8, and the torsion spring 10 in a stretched state. When the thyroid manipulative 4 needs to be used, first pull the handle 6. The handle 6 moves the end of the long pin 5 out of the slot 8. At this time, the fixing plate 3 and the protective box 1 are not engaged. Then, under the action of the torsion spring 10, the fixing plate 3, the connecting shaft 2, and the thyroid manipulative 4 rotate clockwise, that is, the thyroid manipulative 4 rotates to the outside of the protective box 1 for easy use. While the fixing plate 3, the connecting shaft 2, and the thyroid manipulative 4 are rotating, the positioning rod 11 restricts the movement of the manipulative 4. The rotation angles of the fixed plate 3, the connecting shaft 2, and the thyroid manipulative 4 ultimately ensure that the thyroid manipulative 4 is in a vertical position, guaranteeing stability. After using the thyroid manipulative 4, rotating it counterclockwise causes the fixed plate 3 to rotate counterclockwise simultaneously. When the slot 8 rotates to the same horizontal position as the long pin 5, the long pin 5 returns to its original position under the action of the handle 6 and the connecting spring 7, i.e., the long pin 5 enters the slot 8. At this time, the fixed plate 3 is once again engaged with the protective box 1 through the long pin 5. The thyroid manipulative 4 is then stored inside the protective box 1, thus preventing the thyroid manipulative 4 from being contaminated by dust.

[0023] Example 2: A side plate 14 is fixedly connected to the surface of the cover plate 13, and the side plates 14 are symmetrically distributed about the center of the cover plate 13. A first magnet 15 is fixedly connected to the inner wall of the side plate 14, and a second magnet 16 is fixedly connected to the outer wall of the protective box 1. The magnetic poles of the second magnet 16 and the first magnet 15 are opposite at adjacent positions.

[0024] After the thyroid teaching aid 4 is placed inside the protective box 1, the cover plate 13 can be closed. At this time, under the action of the first magnet 15 and the second magnet 16, the side connecting plate 14 drives the cover plate 13 to connect stably with the protective box 1. The operation process is quick and convenient, with good protection, and it slows down the aging process of the thyroid teaching aid 4.

[0025] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0026] 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.
