Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an intelligent negative pressure drainage device for thyroid surgery. Background Technology

[0002] Thyroid surgery is commonly used to treat conditions such as thyroid tumors and hyperthyroidism. During the procedure, surgeons need to remove part of the thyroid gland, which can lead to complications such as postoperative bleeding and fluid accumulation. Therefore, effective postoperative drainage is crucial for reducing complications and promoting recovery. With advancements in medical technology, intelligent devices are increasingly being applied in the surgical field. Intelligent negative pressure drainage devices, by integrating sensors, monitoring systems, and automatic adjustment mechanisms, can monitor drainage in real time and automatically adjust the negative pressure level, thereby improving drainage effectiveness and safety.

[0003] During the surgery, surgical instruments are first used to explore the thyroid gland and surrounding structures to determine the optimal entry point for the drainage tube, avoiding damage to important blood vessels and nerves. Then, the drainage tube is passed through the incision and slowly guided to the cavity that needs drainage (such as the postoperative cavity or fluid accumulation area after thyroid surgery). It is ensured that the end of the drainage tube is accurately positioned and that the drainage tube is not twisted or compressed into the surrounding tissues. However, the head of the drainage tube is made of metal, and thyroid surgery is a delicate procedure. Improper operation during insertion can easily damage nerves. Utility Model Content

[0004] This invention provides an intelligent negative pressure drainage device for thyroid surgery, which has the beneficial effect of preventing the metal tip of the drainage tube from damaging nerves during actual operation.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A thyroid surgical intelligent negative pressure drainage device includes an intelligent negative pressure drainage controller, a drainage tube, and a drainage bag. One end of the drainage bag is connected to the intelligent negative pressure drainage controller, and the other end is connected to the drainage tube. A metal head is provided at the end of the drainage tube. An air bladder is fixedly connected to the external end of the metal head away from the drainage tube. The internal structure of the metal head has a cavity that communicates with the air bladder. An inflation tube is connected to the end of the metal head.

[0007] Optionally, the inflation tube is fixedly connected to the inner wall of the drainage tube and is embedded in the inner wall of the guide tube.

[0008] Optionally, the end of the metal head is provided with an air hole.

[0009] Optionally, the airbag may have a second air hole at the position corresponding to the first air hole.

[0010] Optionally, a rubber sealing tube is fixedly connected to the end of the inflation tube.

[0011] Optionally, the connection between the inflation tube and the drainage tube is sealed.

[0012] Optionally, the outer wall of the drainage tube is movably connected to two rotating plates.

[0013] Optionally, magnetic components are fixedly connected to the ends of the two rotating plates.

[0014] This invention provides an intelligent negative pressure drainage device for thyroid surgery, which has the following advantages compared with the prior art:

[0015] An air bladder is provided on the outside of the metal head at the end of the drainage tube. A cavity is provided inside the metal head, and an inflation tube is provided inside the drainage tube. The inflation tube is connected to the metal head. During the insertion of the drainage tube, the metal head can both guide the drainage tube and inflate the air bladder through the inflation tube, causing the air bladder on the outside of the metal head to expand and stretch the surrounding tissue, making it easier to insert the drainage tube into the designated position. At the same time, the air bladder can prevent the metal head from damaging the nerves of the human body due to improper operation during the insertion process. Attached Figure Description

[0023] 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.

[0024] Please see Figures 1 to 6 This utility model provides a technical solution: a thyroid surgical intelligent negative pressure drainage device, including an intelligent negative pressure drainage controller 1, a drainage tube 2 and a drainage bag 3. One end of the drainage bag 3 is connected to the intelligent negative pressure drainage controller 1, and the other end is connected to the drainage tube 2. A metal head 4 is provided at the end of the drainage tube 2. An air bladder 5 is fixedly connected to the end of the metal head 4 away from the drainage tube 2. The internal structure of the metal head 4 has a cavity 6, which is connected to the air bladder 5. An inflation tube 7 is connected to the end of the metal head 4.

[0025] In use, connect the drainage tube 2 to one end of the drainage bag 3, and connect the other end of the drainage bag 3 to the intelligent negative pressure drainage controller 1, ensuring that all connections are sealed. Inflate the inflation tube 7 using an injection needle or other tools. The gas enters the cavity 6 of the metal head 4 from the inflation tube 7, and then enters the air bag 5, causing the air bag 5 to inflate. Then, insert the metal head 4 at the end of the drainage tube 2 into the patient's desired drainage location. During the insertion of the drainage tube 2, the air bag 5 can expand the surrounding tissues, and the metal head 4 can guide the drainage tube 2. Then, activate the intelligent negative pressure drainage controller 1 and set the negative pressure value according to the doctor's instructions to ensure the device operates normally, keeping the inside of the drainage tube 2 under negative pressure. This allows the drainage fluid from the thyroid gland to be drawn into the drainage bag 3 through the drainage tube 2. This provides a buffer even if improper operation occurs during insertion, preventing the metal head 4 from directly contacting the nerve and causing nerve damage. After the drainage tube 2 is inserted, the gas in the air bag 5 can be emptied.

[0026] Furthermore, the inflation tube 7 is fixedly connected to the inner wall of the drainage tube 2 and is embedded in the inner wall of the guide tube.

[0027] Please see Figure 3 , Figure 6 When drainage fluid passes through the drainage tube 2, the resistance to flow can be reduced to a certain extent.

[0028] Furthermore, the end of the metal head 4 is constructed with an air hole 8.

[0029] Please see Figure 3 , Figure 4The pore-8 can effectively avoid tissue damage or complications caused by excessive negative pressure during drainage. It can balance internal and external pressure and prevent excessive negative pressure from affecting surrounding tissues.

[0030] Furthermore, the airbag 5 has an air pore 9 at the position corresponding to the air pore 8.

[0031] Please see Figure 4 The position of vent 29 corresponds to the position of vent 18, to prevent vent 18 from being blocked after the airbag 5 is inflated.

[0032] Furthermore, a rubber sealing tube 10 is fixedly connected to the end of the inflation tube 7.

[0033] Please see Figure 3 The rubber sealing tube 10 can effectively prevent gas from leaking from the end of the inflation tube 7, ensuring that the gas inside the airbag 5 is kept at a set negative pressure, and also makes it easy to inject gas into the inflation tube 7 with a syringe-like device.

[0034] Furthermore, the connection between the inflation tube 7 and the drainage tube 2 is sealed.

[0035] Please see Figure 3 The sealed connection prevents external air and bacteria from entering the drainage tube 2 through the connection. The sealed state ensures that the pressure inside the drainage tube 2 is maintained within the set range, which helps to form a stable negative pressure state, thereby promoting the effective drainage of the drainage fluid.

[0036] Furthermore, two rotating plates 11 are movably connected to the outer wall of the drainage tube 2.

[0037] Please see Figure 2 This allows the position of the rotating plate 11 to be adjusted as needed, making it easy to operate.

[0038] Furthermore, magnetic components 12 are fixedly connected to the ends of the two rotating plates 11.

[0039] Please see Figure 2 The magnetic components 12 have magnetic force between them and can attract each other. The magnetic components 12 can be set to any shape such as sphere or square. The drainage tube 2 can be fixed to the clothing through the magnetic components 12, so that it can be fixed when wearing the drainage tube 2 and is also easy to operate.

[0040] Working principle: When using this intelligent negative pressure drainage device for thyroid surgery, first insert the gas-filled injection needle through the rubber sealing tube 10, then inflate the inflation tube 7. The gas then enters the cavity 6 of the metal head 4 from the inflation tube 7, and then enters the balloon 5, causing the balloon 5 to inflate. During this process, the metal head 4 can be inserted and inflated simultaneously, or the balloon 5 can be inflated first, and then the metal head 4 can be inserted into the designated position. In this way, during the insertion of the drainage tube 2, the balloon 5 can expand the surrounding tissue, and at the same time, the metal head 4 can guide the drainage tube 2. After the drainage tube 2 is inserted, the gas in the balloon 5 can be emptied, and then the intelligent negative pressure drainage controller 1 can be activated. The negative pressure value is set according to the doctor's guidance to ensure that the device operates normally, so that the inside of the drainage tube 2 is in a negative pressure state, and the drainage fluid from the thyroid gland is drawn into the drainage bag 3 through the drainage tube 2.

[0041] The standard parts used in this embodiment can be purchased directly from the market, while the non-standard structural parts described in the specification and drawings can be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0042] 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.
