Description

Technical Field

[0001] The invention relates to a medical auxiliary diagnosis tool, in particular to a thyroglossal duct cyst positioning device. Background Art

[0002] Thyroglossal duct cyst (TDC) is the most common non-odontogenic cyst in the neck, accounting for about 70% of all congenital abnormalities of the neck. It is the result of abnormal development and migration of the thyroid gland from the 4th to the 8th week of pregnancy. It is mainly benign in nature, but may occasionally become malignant. It is mostly located in the middle of the front neck. The middle of the front neck is also a common site for ectopic thyroid and thyroglossal duct cysts. Misdiagnosis often occurs, especially in the differential diagnosis of ectopic thyroid cancer and thyroglossal duct cysts.

[0003] 99m TcO4 thyroid SPECT imaging can meet the need to exclude thyroid tissue as the source of thyroglossal duct cysts before surgery. The determination of the positional relationship between the mass and the thyroid gland in the imaging is crucial to the next clinical diagnosis and treatment plan. In clinical practice, lead blocks are often placed at the location of the mass to determine its position with the thyroid gland (specifically, lead blocks are placed on the tumor in clinical practice. If there is a defect in the radioactivity of the thyroid tissue, it means that the mass and the thyroid gland are closely related). However, in clinical practice, it is found that because the masses are often of different sizes, the lead blocks themselves are not easy to cut, and the hardness and shape of the lead blocks themselves make them less stable when placed at the lesion location, which often leads to inaccurate positioning. Therefore, the diagnosis of the above-mentioned lesion relationship using traditional iron blocks is unclear and requires experienced physicians to judge. Summary of the invention

[0004] The present invention aims to overcome the above-mentioned defects and provide a device which has a simple structure, is easy to assemble, and can be adjusted in size according to the thyroglossal duct cyst. The device can be used to locate the thyroglossal duct cyst. The device forms an adjustable ring. Since the thyroid gland itself has imaging properties, if superposition occurs, the result will be very clear.

[0044] The present invention is capable of various modifications and various embodiments, and therefore specific embodiments are illustrated and described in the accompanying drawings. However, this is not intended to limit the present invention to specific implementations, but should be understood to include all modifications, equivalents, and even substitutes that fall within the concept and technical scope of the present invention.

[0045] like Figure 1 As shown, a thyroglossal duct cyst positioning device provided in this embodiment includes a cuttable hose 200 and a developer injection piece 100;

[0046] The developer injection member 100 and the cuttable hose 200 are in a detachable structure;

[0047] The developer injection component comprises a developer injection portion 110 and two wings 120 and 130 in a three-way shape, and the two ends of the two wings 120 and 130 are provided with limiting protrusion structures 121 and 131, and the limiting protrusion structure and the developer injection portion are respectively located at three openings of the three-way, which can accommodate the inflow and outflow of liquid;

[0048] The diameter of the limiting protrusion structures 121 and 131 is larger than the diameter of the cuttable hose, so that when the hose is nested with the limiting protrusion structure during use, a clamping effect can be achieved to prevent it from slipping off and prevent the developer inside from leaking;

[0049] The developer injection part 110 has a one-way valve structure 111, that is, it uses elastic and stretchable materials such as rubber as a seal, and the middle part is a crack. The syringe can inject the developer into the inside from the crack. When the syringe is withdrawn, the sealing effect can be directly achieved due to the elastic effect.

[0050] Taking into account the leakage problem of developer, an opening and closing mechanism, that is, a cover or the like, may be further provided at the injection inlet of the developer injection portion.

[0051] Considering that it is generally formed into a ring, such as Figure 2 As shown, the developer injection piece can be designed to have a curved shape, or the developer injection piece can be made of a deformable material and can be deformed according to the shape of the hose during use.

[0052] like Figure 3 As shown, in another example, the limiting protrusion structure has hook-shaped edges or protrusions 122 and 133;

[0053] In order to match the hook-shaped edges or protrusions 122 and 133 , a plurality of limiting mechanisms are evenly arranged on the inner surface of the cuttable hose; the limiting mechanisms are engaged with the structures of the hook-shaped edges or protrusions 122 and 133 .

[0054] Preferred as Figure 4 As shown, the limiting mechanism 210 is in the shape of a groove. During use, the protrusion is just stuck in the groove to achieve the engagement of the two.

[0055] Alternatively, in order to match the hook-shaped edge, the limiting mechanism can also be a protrusion obliquely arranged on the inner surface of the cuttable hose to achieve a buckling effect.

[0056] Considering that the device is generally arranged at the throat of the human body, it is easy to slip due to slight movement even when lying on one's back. Therefore, an anti-falling positioning mechanism is also provided in the solution of this embodiment.

[0057] Design 1. The positioning mechanism is an adhesive component arranged on the bottom surface of the cuttable hose and / or the developer injection piece, such as an anti-allergic double-sided tape or other components with adhesive function.

[0058] Design 2. The positioning mechanism is as follows Figure 5 The airbag inflatable ring 1 shown is different from the traditional neck fixing ring. The opening and closing position of the airbag inflatable ring is at the side, and the ring-shaped closure is achieved by a buckle or adhesive buckle 3, and the air is inflated and deflated by a balloon 2;

[0059] The airbag inflatable ring 1 has an annular mounting groove 2, which corresponds to the throat. When the patient wears it, it can be fine-tuned by rotating it left and right according to the position to be detected.

[0060] The annular mounting groove 2 thyroglossal duct cyst positioning device is embedded in the annular mounting groove to achieve positioning without falling off.

[0061] Based on the above design, a thyroglossal duct cyst localization device capable of injecting contrast agent, adjusting the size, and being deformable is realized. When the device is used in clinical examination, Figure 6 As shown, the imaging effect is very clear (as shown by the arrows and circles in the figure), which can more accurately identify the relationship between thyroid tissue and tumors.

[0062] Although the above description is centered on the embodiment, it is only an example and does not limit the present invention. It is clear to those skilled in the art that various modifications and applications not illustrated above can be made within the scope of the essential characteristics of the present embodiment. For example, each component specifically shown in the embodiment can be implemented after being modified. Moreover, various differences related to such modifications and applications should be interpreted as being included in the scope of the present invention as defined in the attached claims.
