Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a liposuction bottle for negative pressure liposuction in cosmetic surgery. Background Technology

[0002] Cosmetic medicine refers to cosmetic procedures that use drugs, surgery, medical devices, and other invasive or irreversible medical techniques to repair and reshape a person's appearance and various parts of the body. Liposuction, also known as fat removal or body sculpting, is a procedure that uses instruments inserted through small incisions in the skin to remove fat fragments from the subcutaneous fat layer. It is suitable for body contouring. Liposuction is a cosmetic surgery that uses negative pressure to remove accumulated subcutaneous fat through small incisions in the skin. Its purpose is to improve body shape and treat functional disorders caused by obesity. The suction equipment includes a suction tip, connecting cannula, and negative pressure drainage device. Areas for suction include the abdomen, buttocks, thighs, calves, and jawline.

[0003] For example, patent application number CN202022713640.0 discloses "a liposuction bottle for negative pressure liposuction", which includes a handle, a bottle cap and a bottle body. One side of the bottle cap is glued to the handle. The bottle cap is fixedly connected to one end of the liposuction tube connector. The bottle cap is fixedly connected to the negative pressure tube connector. A fixing structure is provided on the outside of the bottle cap.

[0004] However, the liposuction bottles mentioned above rely on a threaded structure and buckles to fix the cap to the bottle body during use. This method is prone to poor sealing and air leakage, which affects the quality of subsequent negative pressure liposuction. Summary of the Invention

[0005] The purpose of this invention is to solve the problem that the existing technology relies on threaded structures and buckles to fix the bottle cap to the bottle body, but this method is prone to poor sealing and air leakage, which affects the quality of subsequent negative pressure liposuction. Therefore, this invention proposes a liposuction bottle for negative pressure liposuction in medical aesthetics.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A liposuction bottle for negative pressure liposuction in cosmetic surgery includes a liposuction bottle with a top cap on its upper side; It also includes a sealing mechanism for sealing the connection between the top cover and the liposuction bottle. The sealing mechanism includes fixed rods fixedly installed on the left and right sides of the lower end of the top cover. Fixed plates are fixedly installed on both the left and right ends of the liposuction bottle. Fixed holes are opened on the fixed plates corresponding to the fixed rods. A connecting ring is slidably installed on the outer side of the liposuction bottle. A lower sealing ring plate is rotatably installed on the upper end of the connecting ring. The inner side of the lower sealing ring plate is in contact with the liposuction bottle. A groove is opened on the outer side of the liposuction bottle corresponding to the lower sealing ring plate. An inner sealing ring plate is fixedly installed on the lower end of the top cover corresponding to the inner wall of the liposuction bottle. An outer sealing ring plate is fixedly installed on the lower end of the top cover corresponding to the outer wall of the liposuction bottle. A bottle mouth contact ring is formed between the inner sealing ring plate and the outer sealing ring plate corresponding to the upper end of the bottle mouth of the liposuction bottle. A sealing groove is opened on the lower end of the outer sealing ring plate corresponding to the lower sealing ring plate. It also includes a cleaning mechanism for cleaning the adhering substances on the upper and outer surfaces of the lower sealing ring plate. The cleaning mechanism includes a cleaning plate that abuts against and adheres to the surface of the lower sealing ring plate, and a guide rod is fixedly installed on the left end of the cleaning plate.

[0007] Preferably, each of the fixed plates has a slidably mounted stabilizing strip on its upper end, and each fixed rod has a limit insertion hole corresponding to the stabilizing strip. A connecting frame is fixedly mounted at the rear end of each stabilizing strip, and a screw is threaded onto the middle of the connecting frame. The screw is rotatably connected to the rear end of the liposuction bottle.

[0008] Preferably, each of the upper ends of the fixed plate is slidably mounted with a movable inclined block corresponding to the stabilizing bar. A spring is fixedly mounted at the ends of the movable inclined blocks that are far apart from each other. The other end of the spring is fixedly connected to the fixed plate. A slot is opened at each of the movable inclined blocks at the ends of the stabilizing bars that are far apart from each other.

[0009] Preferably, the liposuction bottle has front and rear inclined pressure blocks on both sides of the top cover, and a connecting plate is fixedly installed at the lower end of each of the front and rear inclined pressure blocks. A guide rod is slidably installed through the connecting plate. The ends of the guide rods that are close to each other are fixedly installed on the liposuction bottle, and a spring is sleeved on the outer side of each guide rod.

[0010] Preferably, an L-shaped plate is abutting against the middle of the connecting frame, and the L-shaped plate is fixedly connected to the connecting plate on the rear side. A rack is fixedly installed on the left end of the connecting plate, and a gear shaft meshes between the racks. A support plate is rotatably installed through the upper end of the gear shaft, and the support plate is fixedly connected to the left end of the liposuction bottle.

[0011] Preferably, each of the front and rear inclined pressure blocks is provided with a limiting plate on its left side, and a rotating shaft is fixedly installed at the middle of the right end of each limiting plate. The right end of the rotating shaft is rotatably installed on the front and rear inclined pressure blocks, and a torsion spring is sleeved on the outer side of the rotating shaft.

[0012] Preferably, the liposuction bottle has a top strip fixedly installed on the limiting plates at both ends corresponding to the front and rear sides, and the top cover has a slot on both the front and rear sides corresponding to the limiting plates.

[0013] Preferably, a connecting plate 2 is slidably installed through the middle of the guide rod 2, a spring 3 is sleeved on the outer side of the guide rod 2, a rotating rod is fixedly installed at the left end of the guide rod 2, and the lower end of the rotating rod is rotatably installed on the connecting ring.

[0014] Preferably, a limiting plate two is slidably installed on the upper end of the connecting ring corresponding to the rotating rod, and a thread is opened on the outer side of the gear shaft corresponding to the connecting ring, so that the connecting ring is threadedly connected to the gear shaft.

[0015] Preferably, a scraper plate is slidably sleeved on the outer side of the fixed rod, and a guide rod three is fixedly installed on the upper end of the scraper plate. A spring four is sleeved on the outer side of the guide rod three, and the upper end of the guide rod three is movably installed on the top cover.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, the fixed rod on the top cover is aligned with the fixed hole and inserted into the fixed plate. After the fixed rod is inserted into the fixed hole, the limiting insertion hole is located at the front side of the stabilizing strip. Rotating the screw drives the connecting frame to move forward, and the connecting frame drives the stabilizing strips on both sides to move synchronously. The stabilizing strip is gradually inserted into and passes through the limiting insertion hole. The stabilizing strip makes it easy to fix the fixed rod on the fixed plate, preventing the fixed rod from loosening from the fixed hole, which would cause loosening and air leakage at the connection between the top cover and the liposuction bottle, thereby improving the stability of the subsequent negative pressure liposuction of the liposuction bottle.

[0017] 2. In this invention, as the stabilizing bar gradually penetrates the limiting insertion hole, the front end of the stabilizing bar will contact and push the inclined surface of the movable inclined block. The movable inclined block will slide in opposite directions away from each other on the fixed plate, compressing the first spring. When the first slot moves to the side where the movable inclined blocks are close to each other, the first spring will drive the movable inclined blocks on both sides to reset, so that the movable inclined block is inserted into the first slot. The movable inclined block is designed to limit and fix the stabilizing bar, avoiding the situation where the stabilizing bar is pushed out of the limiting insertion hole by the screw due to external force, resulting in an unstable connection between the top cover and the liposuction bottle. This effectively ensures the stable sealing of the connection between the top cover and the liposuction bottle.

[0018] 3. In this invention, when the connecting frame moves backward, it also drives the L-shaped plate to move backward synchronously. The L-shaped plate drives the rear connecting plate and the rear front and rear inclined pressure blocks to move backward synchronously. At the same time, the racks and gear shafts on both sides drive the front connecting plate and the front front and rear inclined pressure blocks to move backward synchronously. At this time, the front and rear inclined pressure blocks on both sides move in a direction that approaches each other until the inclined surfaces of the front and rear inclined pressure blocks on both sides press against the front and rear sides of the top cover. The front and rear inclined pressure blocks facilitate the pressing and fixing of the front and rear sides of the top cover, which improves the sealing between the top cover and the liposuction bottle. It also prevents the front and rear sides of the top cover from being subjected to external force, causing the liposuction bottle to tilt outward and leak air. This ensures the firm sealing between the top cover and the liposuction bottle and guarantees the subsequent negative pressure liposuction effect.

[0019] 4. In this invention, when the front and rear inclined pressure blocks on both sides move closer to each other, they will also drive the rotating shaft, torsion spring and limiting plate 1 on both sides to move synchronously. The top bar will contact and push the limiting plate 1 to drive the rotating shaft to rotate on the front and rear inclined pressure blocks, compressing the torsion spring. When the front and rear inclined pressure blocks on both sides press and fix the front and rear sides of the top cover, the limiting plate 1 on both sides will also be locked in the slot 2. The limiting plate 1 can not only improve the stability and sealing of the front and rear inclined pressure blocks pressing the top cover, but also limit the top cover to avoid the top cover from shaking and becoming unstable. This improves the stability of the connection between the top cover and the liposuction bottle and ensures the quality of subsequent negative pressure liposuction.

[0020] 5. In this invention, after the top cover and the liposuction bottle are fixed, the outer wall of the inner sealing ring plate will abut against the inner wall of the upper side of the liposuction bottle, and the inner wall of the outer sealing ring plate will abut against the outer wall of the upper side of the liposuction bottle. The upper end of the liposuction bottle opening will abut against and fit with the bottle mouth contact ring. When the gear shaft rotates, it will also drive the connecting ring and the lower sealing ring plate to rise synchronously through the set thread. The lower sealing ring plate will be inserted into the sealing groove, which facilitates the sealing of the connection between the outer sealing ring plate and the lower end of the liposuction bottle, thereby improving the sealing performance between the top cover and the liposuction bottle.

[0021] 6. In this invention, pressing down on the guide rod three drives the scraper plate to move downward, compressing the spring four. The scraper plate facilitates the cleaning of the adhesive material adhering to the outer surface of the fixed rod, preventing the adhesive material from affecting the normal insertion of the fixed rod into the fixed hole, or causing the fixed rod and the fixed hole to rub against each other for a long time, resulting in gaps and affecting the stable sealing between the top cover and the liposuction bottle.

[0022] 7. In this invention, the lower sealing ring plate is rotated on the connecting ring. The cleaning blade facilitates the scraping of the adhering material on the outer surface of the lower sealing ring plate, effectively preventing the adhering material from causing gaps between the lower sealing ring plate and the sealing groove or the outer sealing ring plate, which would affect the subsequent negative pressure operation, thereby improving the quality of subsequent negative pressure liposuction.

[0023] 8. In this invention, pushing the limiting plate two outward and rotating the rotating rod causes the connecting plate two, the guide rod two and the cleaning plate two to rotate, so that the cleaning plate automatically detaches from the outer surface of the limiting plate two and rotates to the side away from the limiting plate two. This not only removes the adhering tissues cleaned by the cleaning plate, but also does not affect the normal insertion of the lower sealing ring plate into the sealing groove.

Fixed plates 4 are fixedly installed on both ends of the liposuction bottle 1, with fixed holes 301 on the fixed plates 4 corresponding to the fixed rods 3. A connecting ring 25 is slidably installed on the outer side of the liposuction bottle 1, and a lower sealing ring plate 26 is rotatably installed on the upper end of the connecting ring 25. The inner side of the lower sealing ring plate 26 is in contact with the liposuction bottle 1, and a groove 2601 is formed on the outer side of the liposuction bottle 1 corresponding to the lower sealing ring plate 26. The lower end of the top cover 2... An inner sealing ring plate 27 is fixedly installed on the inner wall of the liposuction bottle 1, and an outer sealing ring plate 28 is fixedly installed on the lower end of the top cover 2 corresponding to the outer wall of the liposuction bottle 1. A bottle mouth contact ring 29 is formed between the inner sealing ring plate 27 and the outer sealing ring plate 28 at the upper end of the bottle mouth of the liposuction bottle 1. A sealing groove 30 is formed at the lower end of the outer sealing ring plate 28 corresponding to the lower sealing ring plate 26. A stabilizing strip 5 is slidably installed on the upper end of each fixed plate 4, and a limit insertion hole 6 is formed on each stabilizing strip 5 on each fixed rod 3. A connecting frame 7 is fixedly installed at the rear end of each stabilizing strip 5, and a screw 8 is threaded onto the middle of the connecting frame 7. The screw 8 is rotatably connected to the rear end of the liposuction bottle 1. A movable inclined plate is slidably installed on the upper end of each fixed plate 4 corresponding to the stabilizing strip 5. Each of the movable inclined blocks 9 and the movable inclined blocks 9 has a spring 10 fixedly installed at one end, and the other end of the spring 10 is fixedly connected to the fixed plate 4. The stabilizing bars 5 have slots 11 at their ends corresponding to the movable inclined blocks 9. The liposuction bottle 1 has front and rear inclined pressure blocks 12 on both sides corresponding to the top cover 2. A connecting plate 13 is fixedly installed at the lower end of each front and rear inclined pressure block 12. A guide rod 14 is slidably installed through each connecting plate 13. The ends of the guide rods 14 that are close to each other are fixedly installed on the liposuction bottle 1, and a spring 15 is sleeved on the outer side of each guide rod 14. An L-shaped plate 16 is fitted and abutted against the middle of the connecting frame 7. The L-shaped plate 16 and the connecting plate 14 on the rear side... 3. Fixed connection: racks 17 are fixedly installed on the left end of connecting plate 13. Gear shafts 18 mesh between racks 17. Support plate 19 is rotatably installed through the upper end of gear shaft 18. Support plate 19 is fixedly connected to the left end of liposuction bottle 1. Limiting plates 20 are provided on the left side of the front and rear inclined pressure blocks 12. A rotating shaft 21 is fixedly installed in the middle of the right end of the limiting plates 20. The right end of the rotating shaft 21 is rotatably installed on the front and rear inclined pressure blocks 12. A torsion spring 22 is sleeved on the outer side of the rotating shaft 21. Top strips 23 are fixedly installed on the limiting plates 20 corresponding to the front and rear sides of the liposuction bottle 1. The top end of the top cover 2 has slots 24 corresponding to the limiting plates 20 on the front and rear sides. During operation, the fixed rod 3 on the top cover 2 is aligned with the fixed hole 301 and inserted into the fixed plate 4. After the fixed rod 3 is inserted into the fixed hole 301, the limiting insertion hole 6 is located in front of the stabilizing bar 5. Rotating the screw 8 drives the connecting frame 7 to move forward, and the connecting frame 7 drives the stabilizing bars 5 on both sides to move synchronously. The stabilizing bar 5 gradually inserts into and passes through the limiting insertion hole 6. The stabilizing bar 5 is designed to fix the fixed rod 3 on the fixed plate 4, preventing the fixed rod 3 from loosening from the fixed hole 301, which would cause loosening and air leakage at the connection between the top cover 2 and the liposuction bottle 1. This improves the stability of the subsequent negative pressure liposuction of the liposuction bottle 1. When the stabilizing bar 5 gradually passes through the limiting insertion hole 6, the front end of the stabilizing bar 5 will contact and push the inclined surface of the movable inclined block 9. The movable inclined block 9 will move away from each other on the fixed plate 4. Sliding and compressing spring 10 until the slot 11 moves to the side where the movable inclined blocks 9 are close to each other, spring 10 drives the movable inclined blocks 9 on both sides to reset, so that the movable inclined blocks 9 are inserted into the slot 11. The movable inclined blocks 9 are designed to limit and fix the stabilizing strip 5, preventing the screw 8 from being pushed by external force and causing the stabilizing strip 5 to fall out of the limiting insertion hole 6, resulting in an unstable connection between the top cover 2 and the liposuction bottle 1. This effectively ensures the stable sealing of the connection between the top cover 2 and the liposuction bottle 1. When the connecting frame 7 moves backward, it will also drive the L-shaped plate 16 to move backward synchronously. The L-shaped plate 16 drives the connecting plate 13 on the rear side and the front and rear inclined pressure blocks 12 on the rear side to move backward synchronously. At the same time, the racks 17 and gear shafts 18 on both sides drive the front side The connecting plate 13 and the front and rear inclined pressure blocks 12 move backward synchronously. At this time, the front and rear inclined pressure blocks 12 on both sides move towards each other until the inclined surfaces of the front and rear inclined pressure blocks 12 on both sides press against the front and rear sides of the top cover 2. The front and rear inclined pressure blocks 12 are designed to press and fix the front and rear sides of the top cover 2, which improves the sealing between the top cover 2 and the liposuction bottle 1, and also prevents the front and rear sides of the top cover 2 from tilting outward and leaking air due to external force. This ensures the firm sealing between the top cover 2 and the liposuction bottle 1, and guarantees the subsequent negative pressure liposuction effect. When the front and rear inclined pressure blocks 12 on both sides move towards each other, they will also drive the rotating shafts 21, torsion springs 22 and limiting plates 20 on both sides to move synchronously. The top bar 23 will contact and... Pushing the limiting plate 20 causes the rotating shaft 21 to rotate on the front and rear inclined pressure blocks 12, compressing the torsion spring 22. When the front and rear inclined pressure blocks 12 on both sides press and fix the front and rear sides of the top cover 2, the limiting plates 20 on both sides also engage in the slots 24. The limiting plates 20 not only improve the stability and sealing of the top cover 2 when pressed by the front and rear inclined pressure blocks 12, but also limit the top cover 2, preventing it from shaking or becoming unstable. This improves the stability of the connection between the top cover 2 and the liposuction bottle 1, ensuring the quality of subsequent negative pressure liposuction. After the top cover 2 and the liposuction bottle 1 are fixed, the outer wall of the inner sealing ring plate 27 abuts against the inner wall of the upper side of the liposuction bottle 1, and the inner wall of the outer sealing ring plate 28 abuts against the outer wall of the upper side of the liposuction bottle 1.Furthermore, the upper end of the opening of the liposuction bottle 1 abuts against and fits against the bottle mouth contact ring 29. When the gear shaft 18 rotates, it also drives the connecting ring 25 and the lower sealing ring plate 26 to rise synchronously through the set thread. The lower sealing ring plate 26 is inserted into the sealing groove 30, which facilitates the sealing of the connection between the outer sealing ring plate 28 and the lower end of the liposuction bottle 1, thereby improving the sealing performance between the top cover 2 and the liposuction bottle 1.

[0028] As an embodiment of the present invention, a cleaning mechanism for cleaning the adhering substances on the upper and outer surfaces of the lower sealing ring plate 26 is also provided. The cleaning mechanism includes a cleaning piece 31 that abuts against and fits on the surface of the lower sealing ring plate 26. A guide rod 32 is fixedly installed on the left end of the cleaning piece 31. A connecting plate 33 is slidably installed through the middle of the guide rod 32. A spring 34 is sleeved on the outer side of the guide rod 32. A rotating rod 35 is fixedly installed on the left end of the guide rod 32. The lower end of the rotating rod 35 is rotatably installed on the connecting ring 25. A limit plate 36 is slidably installed on the upper end of the connecting ring 25 corresponding to the rotating rod 35. A thread is opened on the outer side of the gear shaft 18 corresponding to the connecting ring 25. The connecting ring 25 is threadedly connected to the gear shaft 18. A scraping ring plate 37 is slidably sleeved on the outer side of the fixed rod 3. A guide rod 38 is fixedly installed on the upper end of the scraping ring plate 37. A spring 4 39 is sleeved on the outer side of the guide rod 38. The upper end of the guide rod 38 is movably installed through the top cover 2. During operation, pressing down on guide rod 38 moves scraper plate 37 downward, compressing spring 4 39. Scraper plate 37 facilitates the cleaning of adhering material from the outer surface of fixed rod 3, preventing it from interfering with the normal insertion of fixed rod 3 into fixed hole 301 or causing friction between fixed rod 3 and fixed hole 301 over a long period, resulting in gaps and affecting the stable seal between top cover 2 and liposuction bottle 1. Moving lower sealing ring plate 26 causes it to rotate on connecting ring 25, and cleaning blade 31 facilitates the scraping of adhering material from the outer surface of lower sealing ring plate 26 as it passes. In addition, this effectively avoids gaps between the lower sealing ring plate 26 and the sealing groove 30 or the outer sealing ring plate 28 caused by adhering tissue, which could affect subsequent negative pressure operation, thus improving the quality of subsequent negative pressure grease suction. Pushing the limiting plate 36 outwards and rotating the rotating rod 35 causes the connecting plate 33, guide rod 32, and cleaning plate 31 to rotate, causing the cleaning plate 31 to automatically detach from the outer surface of the limiting plate 36 and rotate to a side away from the limiting plate 36. This not only removes the adhering tissue cleaned by the cleaning plate 31 but also does not affect the normal insertion of the lower sealing ring plate 26 into the sealing groove 30.

[0029] Working principle: In use, the fixed rod 3 on the top cover 2 is aligned with the fixed hole 301 and inserted into the fixed plate 4. After the fixed rod 3 is inserted into the fixed hole 301, the limiting insertion hole 6 is located at the front side of the stabilizing bar 5. Rotating the screw 8 drives the connecting frame 7 to move forward, and the connecting frame 7 drives the stabilizing bars 5 on both sides to move synchronously. The stabilizing bar 5 gradually inserts into and passes through the limiting insertion hole 6. The stabilizing bar 5 is designed to fix the fixed rod 3 on the fixed plate 4, preventing the fixed rod 3 from loosening from the fixed hole 301, which would cause loosening and air leakage at the connection between the top cover 2 and the liposuction bottle 1, thereby improving the stability of the subsequent negative pressure liposuction of the liposuction bottle 1. When the stabilizing bar 5 gradually passes through the limiting insertion hole 6, the front end of the stabilizing bar 5 will contact and push the inclined surface of the movable inclined block 9. The movable inclined block 9 will move away from each other on the fixed plate 4. The reverse sliding compresses the spring 10 until the slot 11 moves to the side where the movable inclined blocks 9 are close to each other. The spring 10 then drives the movable inclined blocks 9 on both sides to reset, so that the movable inclined blocks 9 are inserted into the slot 11. The movable inclined blocks 9 are designed to limit and fix the stabilizing strip 5, preventing the screw 8 from being pushed by external force and causing the stabilizing strip 5 to fall out of the limiting insertion hole 6, which would lead to an unstable connection between the top cover 2 and the liposuction bottle 1. This effectively ensures the stable sealing of the connection between the top cover 2 and the liposuction bottle 1. When the connecting frame 7 moves backward, it also drives the L-shaped plate 16 to move backward synchronously. The L-shaped plate 16 drives the connecting plate 13 on the rear side and the front and rear inclined pressure blocks 12 on the rear side to move backward synchronously. At the same time, the racks 17 and gear shafts 18 on both sides drive the front The connecting plate 13 on the side and the front and rear inclined pressure blocks 12 on the front side move backward synchronously. At this time, the front and rear inclined pressure blocks 12 on both sides move towards each other until the inclined surfaces of the front and rear inclined pressure blocks 12 on both sides press against the front and rear sides of the top cover 2. The front and rear inclined pressure blocks 12 are designed to press and fix the front and rear sides of the top cover 2, which improves the sealing between the top cover 2 and the liposuction bottle 1, and also prevents the front and rear sides of the top cover 2 from tilting outward and leaking air due to external force. This ensures the firm sealing between the top cover 2 and the liposuction bottle 1, and guarantees the subsequent negative pressure liposuction effect. When the front and rear inclined pressure blocks 12 on both sides move towards each other, they will also drive the rotating shaft 21, torsion spring 22 and limit plate 20 on both sides to move synchronously. The top bar 23 will contact The limiting plate 20 is pushed to make the rotating shaft 21 rotate on the front and rear inclined pressure blocks 12, compressing the torsion spring 22. When the front and rear inclined pressure blocks 12 on both sides press and fix the front and rear sides of the top cover 2, the limiting plates 20 on both sides are also locked in the slots 24. The limiting plates 20 not only improve the stability and sealing of the front and rear inclined pressure blocks 12 pressing the top cover 2, but also limit the top cover 2 to prevent it from shaking and becoming unstable. This improves the stability of the connection between the top cover 2 and the liposuction bottle 1, ensuring the quality of subsequent negative pressure liposuction. After the top cover 2 and the liposuction bottle 1 are fixed, the outer wall of the inner sealing ring plate 27 will abut against the inner wall of the upper side of the liposuction bottle 1, and the inner wall of the outer sealing ring plate 28 will abut against the outer wall of the upper side of the liposuction bottle 1.Furthermore, the upper end of the opening of the liposuction bottle 1 will abut against and fit against the bottle mouth contact ring 29. When the gear shaft 18 rotates, it will also drive the connecting ring 25 and the lower sealing ring plate 26 to rise synchronously through the set thread. The lower sealing ring plate 26 will be inserted into the sealing groove 30, which facilitates the sealing of the connection between the outer sealing ring plate 28 and the lower end of the liposuction bottle 1, improving the sealing performance between the top cover 2 and the liposuction bottle 1. Pressing down the guide rod 38 will drive the scraper plate 37 to move downward, compressing the spring 4 39. The set scraper plate 37 is convenient for cleaning the adhering tissue on the outer surface of the fixed rod 3, avoiding the adhering tissue from affecting the normal insertion of the fixed rod 3 into the fixed hole 301, or causing the fixed rod 3 and the fixed hole 301 to have a gap due to long-term friction of adhering tissue, which would affect the stability between the top cover 2 and the liposuction bottle 1. For sealing, the lower sealing ring plate 26 is rotated on the connecting ring 25. The cleaning blade 31 is designed to easily scrape off any adhering material on the outer surface of the lower sealing ring plate 26, effectively preventing gaps between the lower sealing ring plate 26 and the sealing groove 30 or the outer sealing ring plate 28 caused by the adhering material, which could affect subsequent negative pressure operation. This improves the quality of subsequent negative pressure grease suction. Pushing the limiting plate 36 outward and rotating the rotating rod 35 causes the connecting plate 33, guide rod 32, and cleaning blade 31 to rotate, causing the cleaning blade 31 to automatically detach from the outer surface of the limiting plate 36 and rotate to the side away from the limiting plate 36. This not only removes the adhering material cleaned by the cleaning blade 31 but also does not affect the normal insertion of the lower sealing ring plate 26 into the sealing groove 30.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
