Description

Technical Field

[0001] This utility model relates to the field of medical drainage tube technology, and in particular to a double-lumen drainage tube after thyroid endoscopic surgery. Background Technology

[0002] Postoperative hemorrhage drainage is necessary after thyroid endoscopic surgery. The routine drainage method is to use a drainage tube, one end of which is placed directly at the thyroid incision site, and the other end is connected to a drainage bag. Postoperative placement of the drainage tube can reduce blood and fluid accumulation in the surgical area, monitor bleeding volume, prevent tracheal compression, and facilitate the surgeon's observation of bleeding.

[0003] However, bleeding after thyroid endoscopic surgery can be categorized into surgical space bleeding, tunnel bleeding, and bleeding from the thyroid surgical wound. The treatment measures differ depending on the location of the bleeding. In current clinical practice, both oozing from the thyroid region and oozing from the surgical cavity are drained through a single drainage tube, making it difficult to determine the location of the bleeding and thus hindering timely and targeted treatment.

[0004] If drainage is required in the thyroid region and cavity, two drainage tubes and two drainage bags need to be inserted simultaneously. Because of the large number of drainage tubes, the system becomes cluttered, affecting the patient's appearance. Furthermore, the tubes are easily pulled, making them inconvenient for the patient to carry and move around in. Extra care must be taken during activity to prevent displacement of the drainage tubes. Summary of the Invention

[0005] To address the problem of difficulty in determining the bleeding location using conventional single-lumen drainage tubes, this invention provides a double-lumen drainage tube for thyroid endoscopic surgery. By optimizing the single-lumen drainage tube into a double-lumen structure, it can drain bleeding from different sites, thereby clearly identifying the bleeding location. At the same time, it avoids the problems of clutter and difficulty in carrying and moving the patient caused by a large number of drainage tubes.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] The double-lumen drainage tube after thyroid endoscopic surgery includes two tubular tubes arranged side by side. A long strip-shaped separator is integrally formed between the two tubular tubes. The two tubular tubes are connected and fixed by the separator. The two tubular tubes are separated by manually tearing the separator.

[0008] Both hose one and hose two include an integrally formed front section, middle section and rear section. The front section is formed by tearing open the front end of the separator strip and separating hose one and hose two from each other. The two front sections are easy to insert into different drainage positions. The end of the front section is connected to a drainage connector. The rear section is formed by tearing open the rear end of the separator strip and separating hose one and hose two from each other. The end of the rear section is connected to an adapter pipe for easy connection of a drainage device. The rear section is also equipped with a flow stop clamp for easy control of the flow of the pipeline.

[0009] The middle section is equipped with multiple tube clamps. Each tube clamp is bent into a "C" shape to clamp the first and second tubes to prevent the first and second tubes from separating further. The tube clamps are provided with clamp sections at both ends to clamp the patient's clothing and facilitate the fixation of the double-lumen drainage tube.

[0010] Furthermore, both the first and second hoses are made of medical plastic. After the first and second hoses and the separator are integrally formed, the cross-section is shaped like an "8". The first and second hoses are in continuous line contact through the separator, which makes it easy to tear the separator to separate the first and second hoses.

[0011] Furthermore, the front sections of hose one and hose two are of equal or unequal length, which facilitates trimming the length of the front sections to adapt to different drainage positions.

[0012] Furthermore, the drainage connector is a tube with one end closed and the other end open. The closed end of the drainage connector is arc-shaped, and the open end of the drainage connector is inserted into the front section. The open end of the drainage connector is tightly fitted with the inner wall of the front section to achieve locking, which increases the tightness of the connection. The drainage connector has multiple drainage holes, which increases the inflow path of the drainage fluid.

[0013] Furthermore, the rear sections of the first and second hoses are of equal length, and each rear section is connected to the medical drainage device through the adapter to facilitate the drainage fluid entering the drainage device. An anti-bending sleeve is fitted on the rear section between the adapter and the stop clamp to prevent the rear section from kinking and blocking the flow of drainage fluid.

[0014] Furthermore, the number of pipe clamps is at least three, with two pipe clamps respectively arranged at the junction of the middle section and the front section, and at the junction of the middle section and the rear section, to effectively prevent the front section and the rear section from separating further.

[0015] Furthermore, the pipe clamp is a C-shaped piece made of plastic that can be slightly deformed. The two ends of the pipe clamp are bent outwards and in the opposite direction to form a clamp piece. The clamp piece and the end of the pipe clamp form the clamp segment. One end of the clamp segment is closed and the other end is open. The size of the opening of the clamp segment is adjustable. The size of the opening is adjusted by deforming the clamp segment.

[0016] The beneficial effects of this utility model through the above technical solution are:

[0017] This utility model has a reasonable structural design. A separator strip is integrally formed between the first and second flexible tubes, and the separator strip creates a continuous line contact between them. This facilitates tearing the separator strip to separate the first and second flexible tubes. After separation, the first and second flexible tubes can be divided into a front section and a rear section. The front section is inserted into the drainage position within the patient's body, and its length can be cut according to different drainage locations.

[0018] This invention is applied after thyroid endoscopic surgery. The front ends of the first and second flexible tubes are inserted into the thyroid wound in the neck and the cavity outlet, respectively. The drainage fluid from these two different locations is drained through the first and second flexible tubes and then into the drainage device connected at the rear end. This facilitates accurate determination of the bleeding location and amount, allowing for targeted treatment.

[0019] The first and second tubing of this invention are initially connected together. They can be separated according to different drainage locations to form a front section. This front section can be trimmed and its length freely adjusted to facilitate drainage of different areas. The remaining sections of the first and second tubing remain connected and fixed, secured by clamps. This prevents the double-lumen drainage tube from becoming tangled, and the clamps at designated locations prevent further separation of the first and second tubing. The clamp ends have clip sections that can be used to secure the patient's clothing, facilitating the fixation of the double-lumen drainage tube and making it convenient for the patient to carry and move around.

[0026] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings:

[0027] like Figures 1-5 As shown, the double-lumen drainage tube after thyroid endoscopic surgery includes two parallel flexible tubes, tube 1 and tube 2, both made of medical-grade plastic. Initially, tubes 1 and 2 are of equal length and are connected together.

[0028] In this embodiment, a long strip-shaped separator 3 is integrally formed between hose 1 and hose 2, and hose 1 and hose 2 are connected and fixed by the separator 3. By tearing the separator 3, hose 1 and hose 2 can be separated. That is, by pinching the ends of hose 1 and hose 2 with both hands and pulling outward, the separator 3 will break, and hose 1 and hose 2 will be separated.

[0029] To facilitate the separation of hose 1 and hose 2, the separator 3 needs to be able to tear quickly. Therefore, after hose 1, hose 2, and separator 3 are integrally formed, their cross-section is shaped like an "8," and hose 1 and hose 2 form a continuous line contact through the separator 3. Thus, hose 1 and hose 2 can be easily separated by manual pulling.

[0030] Since hose 1 and hose 2 are initially connected, and can be separated by external force, hose 1 and hose 2 can be divided into multiple segments based on whether they are connected or separated. Specifically, both hose 1 and hose 2 include an integrally formed front section 4, middle section 5, and rear section 6, such as... Figure 1 As shown.

[0031] The formation of the front section 4, middle section 5 and rear section 6 is as follows: the front end of the separator strip 3 is torn open, and the first tube 1 and the second tube 2 are separated to form the front section 4. The two front sections 4 are no longer connected but are separated from each other. The front section 4 is used to insert into the corresponding surgical site in the patient's body.

[0032] Here, the lengths of the front section 4 of hose 1 and hose 2 are equal or unequal. Specifically, the lengths of the front sections 4 formed by directly pulling apart hose 1 and hose 2 are equal. Based on the fact that the two front sections 4 are of equal length, they are then cut to make them unequal in length. The purpose of cutting is to adjust the length of the front sections 4 according to the drainage position, ensuring that the length of the front sections 4 is suitable and convenient for insertion into the corresponding position.

[0033] The drainage fluid enters the tubing 1 and tubing 2 from the front section 4. In order to expand the flow path of the drainage fluid, a drainage connector 7 is plugged into the end of the front section 4. The plugging and unplugging connection is to facilitate the installation of the drainage connector 7 on the cut front section 4.

[0034] The drainage connector 7 is a tube closed at one end and open at the other. The closed end of the drainage connector 7 is arc-shaped, and multiple drainage holes 71 are provided on the drainage connector 7. The drainage fluid enters the drainage connector 7 through the drainage holes 71 and then flows into the front section 4. During installation, the open end of the drainage connector 7 is inserted into the front section 4. The open end of the drainage connector 7 fits tightly against the inner wall of the front section 4 to achieve a lock and prevent disengagement. That is, the tight connection between the front section 4 and the drainage connector 7 is achieved through the deformation of the front section 4. Figure 2 As shown.

[0035] Tear open the rear end of the separator strip 3. The two tubing segments 1 and 2 are separated from each other to form the rear segment 6. The two rear segments 6 are no longer connected and are also separate from each other. The rear segment 6 and the middle segment 5 are placed outside the patient's body. The rear segment 6 of tubing segment 1 and the rear segment 6 of tubing segment 2 are of equal length. Tubes 1 and 2 are connected to their respective drainage devices using the rear segment 6.

[0036] Specifically, the end of the rear section 6 is connected to an adapter 8. Each rear section 6 is connected to a medical drainage device via the adapter 8. The medical drainage device can be a drainage bag, and the drainage fluid will eventually enter the drainage bag along the tubing. To control the flow of the tubing, a flow stop clamp 9 is also installed on the rear section 6 to control the flow of tubing 1 and tubing 2. Furthermore, an anti-bending sleeve 10 is fitted on the rear section 6 between the adapter 8 and the flow stop clamp 9. The anti-bending sleeve 10 is harder than the rear section 6 to prevent the rear section 6 from kinking and affecting the flow of fluid.

[0037] After the front section 4 and the rear section 6 are formed, the separator strip 3 is no longer torn apart, and the middle section 5 of hose 1 and hose 2 remains connected and fixed together. To prevent the separator strip 3 from being accidentally torn apart and causing hose 1 and hose 2 to separate further, a pipe clamp 11 is provided on the middle section 5. There are multiple pipe clamps 11, at least three in this case. The pipe clamps 11 are C-shaped pieces made of plastic. Each pipe clamp 11 is bent into a C shape to clamp hose 1 and hose 2. Figure 3 and Figure 4As shown.

[0038] The pipe clamp 11 has a certain elastic deformation capacity. It is used to constrain hose 1 and hose 2, preventing them from further separating. Since there are three pipe clamps 11, two are positioned at the junction of the middle section 5 and the front section 4, and at the junction of the middle section 5 and the rear section 6, respectively. These two clamps are the upper clamp 111 and the lower clamp 112. By defining the specific positions of the upper clamp 111 and the lower clamp 112, the formation of the front section 4 and the rear section 6 can be prevented, thus ensuring a constant length of the middle section 5.

[0039] The principle of this utility model is as follows: In the initial state, hose 1 and hose 2 are separated from each other and have formed the rear section 6, such as... Figure 5 As shown in Figure a; the front section 4 is formed by medical staff pulling and separating it according to different drainage positions. After separation, it can be further trimmed to ensure that the overall length of the front section 4 can adapt to the drainage position and avoid the front section 4 being too long and appearing messy. After the length of the front section 4 is determined, the drainage connector 7 is inserted and connected to the front section 4, and then the tube clamp 11 is placed in the corresponding position, such as... Figure 5 As shown in b.

[0040] Taking drainage after thyroid endoscopic surgery as an example: After the length of the double-lumen drainage tube is adjusted, the front section 4 of tube 1 is inserted into the thyroid wound in the neck according to the drainage procedure, and the front section 4 of tube 2 is inserted into the cavity outlet. Tubes 1 and 2 are each connected to a drainage bag. In this way, bleeding from different locations flows into the corresponding drainage bags, allowing for the identification of the specific bleeding location and the observation of the amount of bleeding, thus enabling targeted treatment. Furthermore, the double-lumen drainage tube is separated at the front section 4 and the rear section 6, while remaining connected and fixed together at the other positions. This structural design avoids the tubes 1 and 2 becoming tangled.

[0041] To optimize the product structure and facilitate the fixation of the double-lumen drainage tube, clamp sections 13 are provided at both ends of the tube clamp 11. Specifically, the two ends of the tube clamp 11 are bent outwards in opposite directions to form clamp pieces 12. The clamp pieces 12 cooperate with the ends of the tube clamp 11 to form clamp sections 13. One end of the clamp section 13 is closed and the other end is open, and the size of the opening of the clamp section 13 is adjustable. The patient's clothing can be inserted through the opening of the clamp section 13 and clamped by the clamp section 13; the elastic deformation of the clamp section 13 is used to clamp the patient's clothing, thereby fixing the tubing 1 and tubing 2 to the patient's clothing and preventing the double-lumen drainage tube from being pulled.

[0042] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the patent claims of this utility model should be included within the scope of the patent application of this utility model.
