Description

Technical Field

[0001] This utility model belongs to the field of saliva suction technology, and in particular relates to an improved saliva suction tube. Background Technology

[0002] During dental treatment, the patient's mouth usually needs to be opened wide enough for the dentist to use instruments. The procedure generates a large amount of saliva, and the extraction or drilling of teeth produces water mist and blood, while cleaning wounds generates wastewater. All of these require the use of a saliva suction tube to remove them from the mouth, ensuring the proper execution of the dental procedure.

[0003] In implantation surgery, the suction effect differs between the surgical and non-surgical areas. Sometimes it is necessary to remove all of the material at once, while at other times it is necessary to avoid aspiration of the implanted material area (including bone powder, periosteum, growth factors, etc.). In order to ensure that the implanted material part can reduce bleeding and have a clear field of vision while avoiding aspiration of the material, an improved suction tube is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide an improved saliva suction tube to solve existing problems.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is an improved saliva suction tube, comprising a tube body, wherein movable chamber one and movable chamber two are respectively opened in the tube body. A filter disc is rotatably connected to the left end inlet of the tube body. A vertical rod is set at the top of the peripheral side of the filter disc. A bevel gear one is set at the top of the vertical rod. A fixing block one is set in movable chamber two. A rotating rod one is inserted through the fixing block one. A bevel gear two is set at the left end of the rotating rod one. A fixing block two is set in movable chamber one. A rotating rod two is inserted through the fixing block two. A universal coupling is set at the left end of the rotating rod two. A movable groove is opened in the peripheral side of the tube body. A locking block is set in the tube body. A friction sleeve is fitted on the peripheral side of the rotating rod two. The peripheral side of the rotating rod two is fixedly connected to the friction sleeve. The movable groove communicates with movable chamber one. Movable chamber one communicates with movable chamber two. The top of the vertical rod is set in movable chamber two. The fixing block one and the rotating rod one are rotatably engaged. A plurality of micropores are opened on the surface of the filter disc.

[0006] Furthermore, the second bevel gear meshes with the first bevel gear, the right end of the first rotating rod is fixedly connected to the other end of the universal coupling, the friction sleeve has a scale on its circumferential side, and the friction sleeve is located in the movable groove.

[0007] This utility model has the following beneficial effects: This invention exposes the circumferential surface of the friction sleeve through a movable groove. Rubbing the circumferential surface of the friction sleeve drives the second rotating rod to rotate. The second rotating rod, via a universal coupling at its left end, drives the first rotating rod to rotate. The first rotating rod then drives the second bevel gear at its left end to rotate. The second bevel gear meshes with the first bevel gear, which in turn drives the filter disc to rotate inside the tube via the upright rod. As the filter disc rotates from vertical to horizontal, its filtration surface is perpendicular to the direction of liquid flow within the tube, effectively intercepting and filtering impurities in the liquid. During implantation, when facing the area containing the transplanted material, the horizontal position of the filter disc prevents transplanted materials such as bone powder, periosteum, and growth factors from being accidentally aspirated into the suction tube. Simultaneously, the rotation of the filter disc is flexible and stable, thanks to the connection of the universal coupling, which allows for flexible angle transmission between the second and first rotating rods, ensuring continuous rotation. When it is necessary to change the state of the filter disc, rubbing the friction sleeve in the opposite direction causes the second rotating rod to rotate in the opposite direction, and through a series of transmissions, the filter disc rotates back from horizontal to vertical. In the vertical direction, the filter disc offers minimal resistance to liquid flow, allowing for the complete removal of saliva, water mist, blood, and other contaminants from the mouth at once, meeting various suction needs. Furthermore, this method of controlling the filter disc's rotation by rubbing the sleeve is simple to operate, enabling dentists to quickly adjust it according to the actual situation during oral treatment, greatly improving the convenience and effectiveness of the saliva suction tube.

[0015] Please see Figures 1-5 As shown, this utility model is an improved saliva suction tube, including a tube body 1. The tube body 1 has a first movable cavity 100 and a second movable cavity 1000. A filter disc 11 is rotatably connected to the left end inlet of the tube body 1. A vertical rod 110 is provided at the top of the side of the filter disc 11. A bevel gear 111 is provided at the top of the vertical rod 110. A fixing block 101 is provided in the second movable cavity 1000. A rotating rod 12 is inserted in the fixing block 101. A bevel gear 120 is provided at the left end of the rotating rod 12. A fixing block 102 is provided in the first movable cavity 100. A rotating rod 13 is inserted in the fixing block 102. A universal coupling 2 is provided at the left end of the rotating rod 13. A movable groove 10 is provided on the side of the tube body 1. A locking block 103 is provided inside the tube body 1.

[0016] Furthermore, a friction sleeve 130 is fitted around the circumference of the rotating rod 13, and the circumference of the rotating rod 13 is fixedly connected to the friction sleeve 130. The movable groove 10 communicates with the movable cavity 100, the movable cavity 100 communicates with the movable cavity 1000, and the top of the upright rod 110 is located inside the movable cavity 1000.

[0017] Furthermore, the first fixed block 101 is rotatably engaged with the first rotating rod 12, the second fixed block 102 is rotatably engaged with the second rotating rod 13, and the surface of the filter disc 11 is provided with several micropores.

[0018] Furthermore, bevel gear 120 meshes with bevel gear 111, the right end of rotating rod 12 is fixedly connected to the other end of universal coupling 2, and the friction sleeve 130 has a scale on its circumferential side and is located in the movable groove 10.

[0019] Furthermore, the friction sleeve 130 can determine the rotation angle of the filter disc 11 by using the scale set on its circumferential side.

[0020] It should be noted that this utility model exposes the circumferential side of the friction sleeve 130 through the movable groove 10. Rubbing the circumferential side of the friction sleeve 130 causes the rotating rod 13 to rotate. The rotating rod 13, through the universal coupling 2 at the left end, drives the rotating rod 12 to rotate. The rotating rod 12 drives the bevel gear 120 at the left end to rotate. The bevel gear 120 meshes with the bevel gear 111, which in turn drives the filter disc 11 to rotate inside the tube 1 via the upright rod 110. When the filter disc 11 rotates from the vertical direction to the horizontal direction, its filter surface is perpendicular to the liquid flow direction inside the tube 1, effectively intercepting and filtering impurities in the liquid. When facing the area of ​​the transplanted material during implantation, the filter disc 11 is in a horizontal state, preventing transplanted materials such as bone powder, periosteum, and growth factors from being accidentally aspirated into the suction tube. Meanwhile, the rotation of the filter disc 11 is flexible and stable, thanks to the connection of the universal coupling 2, which allows for flexible angle transmission between the rotating rod 2 13 and the rotating rod 12, ensuring continuous rotation. When it is necessary to change the state of the filter disc 11, the friction sleeve 130 is rubbed in the opposite direction, causing the rotating rod 2 13 to rotate in the opposite direction. Through a series of transmissions, the filter disc 11 rotates from the horizontal direction back to the vertical direction. In the vertical direction, the filter disc 11 provides less resistance to liquid flow, allowing for the complete removal of saliva, water mist, blood, and wastewater from the oral cavity to meet different suction needs. Moreover, this method of controlling the rotation of the filter disc 11 by rubbing the friction sleeve 130 is simple to operate, allowing doctors to quickly adjust according to the actual situation during oral treatment, greatly improving the convenience and effectiveness of the saliva suction tube.
