Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to a thyroid double-cavity drainage structure. Background Art
[0002] Inserting a drainage tube is a common surgical procedure. It allows fluid accumulation in the surgical area to be removed from the body, making it easier to observe the nature of the effusion and determine whether there are complications such as bleeding or infection. If the effusion is large, it can also play a therapeutic role, reducing tension in the surgical area, draining bloody or purulent fluid, and preventing disease progression. The thyroid gland has a rich blood supply, and postoperative bleeding is one of the most common complications. Because the thyroid gland is adjacent to the trachea, the increased hematoma pressure caused by progressive bleeding can narrow the airway and, in severe cases, pose a risk of suffocation. Therefore, unobstructed drainage is particularly important for thyroid surgery, especially complex procedures such as total thyroidectomy combined with cervical lymph node dissection.
[0003] Currently, the commonly used thyroid drainage tube is a single-lumen drainage tube with a negative pressure ball, which has a good effect on unilateral drainage. However, for situations where bilateral drainage is required, two tubes need to be placed or the single drainage tube needs to be split longitudinally to form two silicone sheets for drainage on both sides. Both methods have their limitations: the former will add an additional drainage incision on the neck, affecting the appearance and healing, and requires two drainage tubes, wasting medical resources; the latter silicone sheet drainage connection does not fit tightly with the incision, the negative pressure drainage effect is poor, and additional operation is required to cut the drainage tube, which is inconvenient. Summary of the Invention
[0004] The purpose of the present utility model is to solve the above problems and provide a thyroid double-chamber drainage structure with a simple structure and easy use. It can be applied to unilateral thyroid surgery with a large surgical range, and can also perform bilateral drainage in complex total resection surgery. Moreover, the length and angle of the drainage branch can be determined according to clinical needs. The operation is simple and quick, and the drainage effect and patient comfort are good.
[0005] To achieve the above-mentioned purpose of the utility model, the utility model provides a thyroid double-cavity drainage structure, comprising: a double-cavity drainage tube having two drainage cavities that can be used simultaneously or selectively; a single-cavity connecting tube installed at one end of the double-cavity drainage tube and having an inner cavity that is simultaneously connected to the two drainage cavities of the double-cavity drainage tube; a drainage tube connected to the connecting tube at one end; and a negative pressure ball connected to the other end of the drainage tube.
[0006] Preferably, the double-lumen flow guide tube includes a first flow guide tube and a second flow guide tube arranged in parallel.
[0007] Preferably, the double-lumen flow guide tube further comprises a connector connecting the side walls of the first flow guide tube and the second flow guide tube.
[0008] Preferably, the connecting piece is a thin rubber strip on which an easily tearable wedge-shaped groove or a dotted line is provided.
[0009] Preferably, the side walls of the first flow guiding tube and the second flow guiding tube are respectively provided with through holes for facilitating drainage.
[0010] Preferably, the outer diameter of the connecting tube is greater than or equal to the outer diameter of the drainage tube.
[0011] Compared with the existing technology, the thyroid double-chamber drainage structure of the present invention has the following advantages:
[0012] 1. The utility model has a double-chamber thyroid drainage structure with a simple structure and is easy to use. It can be applied to unilateral thyroid surgery with a large surgical range, and can also perform bilateral drainage in complex total resection surgery. The length and angle of the drainage branch can be determined according to clinical needs. The operation is simple and quick, and the drainage effect and patient comfort are good.
[0013] 2. The utility model has a double-lumen thyroid drainage structure. Its double-lumen drainage tube has two drainage cavities. Compared with the traditional single-lumen drainage tube, it can achieve bilateral and multi-site drainage with a single drainage tube, eliminating the need to place multiple tubes or cut them longitudinally. The patient has fewer incisions, saving medical costs, and the drainage effect is good and convenient. Compared with the traditional Y-shaped double-lumen drainage tube, the utility model has a wider range of uses and is more flexible. The connection angle of the two drainage tubes can be freely selected from 0-180 degrees, and the length can also be selected as needed, which better matches clinical needs and individualized drainage strategies for different patients.

[0019] like Figure 1 As shown in FIG, it is a schematic diagram of the structure of the double-chamber thyroid drainage structure of the present invention. Figure 2-Figure 4As shown in the figure, it is a schematic diagram of the structure of the double-lumen drainage tube in different states of the present invention. As can be seen from the figure, the double-lumen drainage structure of the thyroid gland of the present invention includes: a double-lumen drainage tube 1 with two drainage cavities, and the two drainage cavities can be used simultaneously or selectively; a single-lumen connecting tube 2 installed at one end of the double-lumen drainage tube and the inner cavity of which is connected to the two drainage cavities of the double-lumen drainage tube at the same time; a drainage tube 3 connected to the connecting tube at one end; and a negative pressure ball 4 connected to the other end of the drainage tube.
[0020] Specifically, such as Figure 2-Figure 4 As shown, the double-lumen flow guide tube of the present invention includes a first flow guide tube 11 and a second flow guide tube 12 arranged in parallel, and further includes a connector 13 connecting the side walls of the first flow guide tube and the second flow guide tube.
[0021] Wherein, the first drainage tube and the second drainage tube are both hollow tubes, and the inner cavity of the hollow tube can be a circular cavity or a cross-shaped cavity to prevent the drainage tube from being blocked.
[0022] The side walls of the first and second flow guide tubes are respectively provided with a plurality of through holes 14 for facilitating drainage. The through holes can be circular or elliptical, and the through holes connect the inner cavity of the corresponding flow guide tube with the outside air.
[0023] The connecting piece connecting the opposite side walls of the first and second drainage tubes can be a thin rubber strip. In order to facilitate the use of instruments to cut or tear the thin rubber strip by hand in clinical use, the utility model provides an easy-to-tear wedge-shaped groove 13 or a dotted line on the thin rubber strip. When the wedge-shaped groove is provided, the wedge-shaped groove can be opened on both symmetrical sides of the rubber strip (see Figure 3 ), and extends downward from the upper end along the length of the rubber strip. When a dotted line is set, the dotted line is set along the length extension direction of the rubber strip and can extend from the upper end to the lower end of the rubber strip.
[0024] The rubber strip can be the same length as the first and second flow-conducting tubes, or slightly shorter. During manufacturing, the rubber strip can be integrally formed with the first and second flow-conducting tubes, or can be manufactured separately and then affixed to opposing sidewalls of the first and second flow-conducting tubes by gluing.
[0025] The utility model connects the lumens of the first flow guiding tube and the second flow guiding tube through a connecting tube, and then connects the negative pressure ball and the connecting tube through another flow guiding tube.
[0026] The connecting tube can be a single-lumen silicone tube, which connects the double-lumen drainage tube and the drainage tube. The outer diameter of the connecting tube is equal to the outer diameter of the double-lumen drainage tube connection, but larger than the diameter of the drainage tube, so that the connecting tube and the drainage tube form a step-shaped structure, which facilitates tying and securing the drainage tube at the step after suturing.
[0027] Among them, the double-lumen drainage tube, connecting tube, drainage tube and negative pressure ball can all be made of silicone. During production, the double-lumen drainage tube, connecting tube and drainage tube can be formed in one piece, and the negative pressure ball is made separately. The negative pressure ball is inserted into the distal end of the drainage tube through the interface thereon so as to be connected with the above-mentioned tube bodies. This connection method is used to facilitate the selection and use of the negative pressure ball according to clinical needs. In addition, the double-lumen drainage tube, connecting tube, drainage tube and negative pressure ball can also be formed in one piece during production. The negative pressure ball adopts the existing medical negative pressure ball structure, which will not be described in detail here.
[0028] During clinical use, for unilateral deep thyroid surgery with a large surgical area, the two drainage tubes can be separated without following the grooves or dotted lines on the strips. Instead, the two lumens of the two drainage tubes can be placed in parallel to drain the same area to ensure adequate drainage. When multi-point or multi-level drainage is required, the two drainage tubes can be separated along the grooves or dotted lines on the strips to the required appropriate length (e.g. Figure 4 (As shown), one drainage tube is placed deep, and the other is placed shallowly or in a concave area to ensure adequate drainage and avoid blind cavities. For patients undergoing bilateral thyroid surgery requiring drainage, the double-lumen drainage tube can be divided into two branches along the groove or dotted line and placed in the left and right surgical areas. The indwelling drainage tube is routinely placed percutaneously through a single incision, secured with needle and suture, and then connected to a vacuum bulb.
[0029] Compared with the traditional single-lumen drainage tube, the utility model of the double-lumen thyroid drainage structure can achieve bilateral and multi-site drainage through a single drainage tube, without the need to place multiple tubes or cut the drainage tubes longitudinally, etc., with fewer incisions for patients, saving medical costs, and good drainage effect, convenient and fast. Compared with the traditional Y-shaped double-lumen drainage tube (the traditional Y-shaped double-lumen drainage tube is mostly Y-shaped drainage, with a fixed angle at the connection, and the two drainage tubes are not flexible in the placement angle in the incision, and the structure in the wound is thicker when the tube is removed, and the patient feels more uncomfortable), the utility model of the double-lumen thyroid drainage structure has a wider range of use and is more flexible. The connection angle of the two drainage tubes can be freely selected from 0-180°, and the length can also be selected as needed, which better matches clinical needs and individualized drainage strategies for different patients.
[0030] Although the utility model is described in detail above, the utility model is not limited thereto. Those skilled in the art can make modifications based on the principles of the utility model. Therefore, all modifications made in accordance with the principles of the utility model should be understood to fall within the scope of protection of the utility model.
