Description

Technical Field

[0001] The utility model relates to a dental surgical instrument, in particular to an adjustable non-invasive oral saliva suction tube. Background Art

[0002] The oral saliva suction tube is one of the indispensable instruments in the oral treatment process, and it plays an important role in the treatment. The main function is to suck away the saliva and blood in the patient's mouth, as well as the cooling water produced by high-speed mobile phones, dental cleaning heads and other instruments during work. The oral saliva suction tube is required in various oral treatment processes such as tooth preparation and oral cleaning. However, the saliva suction tube can easily cause damage to soft tissues such as the tongue and oral mucosa through long-term suction with negative pressure, which can make the patient feel uncomfortable and may even cause fear and refuse to cooperate with the doctor's treatment.

[0003] Especially for patients with mandibular edentulism, severe edentulism, and hypertrophic tongue, the saliva suction tube often affects the work efficiency because it sucks the oral soft tissue during use. In severe cases, the saliva suction tube may even stop suctioning, which undoubtedly brings great trouble to the doctor's treatment work. In order to ensure the progress of the treatment, the doctor needs to constantly adjust the position of the saliva suction tube, which not only increases the difficulty of the doctor's work, but also reduces the patient's comfort during the visit.

[0004] At present, the saliva suction tubes used in clinical practice generally produce continuous noise during operation due to the rapid airflow passing through the suction head, which generates vibrations in the tube. This noise affects the quality of diagnosis and treatment services and brings inconvenience to both patients and doctors. Therefore, how to reduce the negative impact of saliva suction tubes and improve the patient's treatment experience is an issue that dentists and device developers need to pay attention to and solve.

[0022] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0023] In order to thoroughly understand the present invention, detailed steps and detailed structures will be presented in the following description to illustrate the technical solution of the present invention. The preferred embodiments of the present invention are described in detail below, but in addition to these detailed descriptions, the present invention may also have other implementations.

[0024] Reference Figure 1 As shown, the utility model provides an adjustable non-invasive oral saliva suction tube, which includes a saliva suction tube body, which is composed of a primary suction head 100 detachably connected to a secondary suction head 200 at the front end of the primary suction head 100.

[0025] First level suction head 100

[0026] The first-level suction tip 100 is a medical-grade transparent soft tube body, which is not only soft and durable, but also has good biocompatibility, which can reduce the stimulation to the patient's oral soft tissue. A metal wire 110 is provided in the side wall of the first-level suction tip 100 for maintaining the shape after bending, so that the first-level suction tip 100 can maintain a certain shaping effect after bending, which is convenient for the doctor to adjust its shape during use. A first end cap 120 is provided at the front end of the first-level suction tip 100, and a threaded hole 121 is provided in the middle of the first end cap 120. The first end cap 120 has a certain thickness to ensure strength and bonding strength with the fixing screw 220. A plurality of strip-shaped first saliva suction holes 122 are provided on the front side wall of the first-level suction tip 100, and the front end opening of the first saliva suction hole 122 extends to the first end cap 120 to increase the suction area. An outer retaining ring 130 protruding from the outer diameter of the first-level suction tip 100 is provided at the rear end of the first saliva suction hole 122.

[0027] Secondary suction head 200

[0028] The secondary suction head 200 is a metal wire mesh tubular structure that can be compressed and deformed. The front end of the secondary suction head 200 is provided with a second end cover 210 with a center hole 211. The secondary suction head 200 is sleeved on the front end of the primary suction head 100 and the rear end of the secondary suction head 200 abuts on the outer retaining ring 130. The secondary suction head 200 is connected to the primary suction head 100 by a fixing screw 220. The fixing screw 220 passes through the center hole 211 of the second end cover 210 and is threadedly connected with the threaded hole 121. The length of the secondary suction head 200 can be changed by rotating the fixing screw 220.

[0029] When the oral saliva suction tube is needed clinically, we first adjust the patient's body position, put the secondary suction head 200 on the outside of the primary suction head 100, and the bottom of the secondary suction head 200 is in close contact with the outer retaining ring 130 of the primary suction head 100. Use the fixing screw 220 to pass through the secondary suction head 200 and threadedly cooperate with the threaded hole 121 of the primary suction head 100, and fix the secondary suction head 200 on the front end of the primary suction head 100.

[0030] Observe whether the oral mucosa and other soft tissues at the suction position are sucked into the opening of the suction head. If the soft tissue is still sucked into the opening under normal negative pressure suction, the fixing screw 220 can be properly tightened to shorten the length of the secondary suction head 200 and increase the diameter of the middle section. The deformation of the secondary suction head 200 can be used to push away the oral soft tissue, thereby improving the suction efficiency and avoiding damage to the oral soft tissue.

[0031] In an optional embodiment, the second end cap 210 is provided with a plurality of second saliva suction holes 212 arranged around the central hole 211 to increase the saliva suction capacity of the saliva suction tube. At the same time, the design of the second saliva suction holes 212 can further reduce the pressure on the patient's oral soft tissue and further reduce the patient's discomfort.

[0032] In an optional embodiment, the first saliva suction hole 122 is a strip hole, and the second saliva suction hole 212 is a round hole. This design can not only optimize the saliva suction effect, but also improve the comfort of the patient. The first saliva suction hole 122 with a strip hole can more effectively capture and guide fluids such as saliva, blood and cooling water, while the second saliva suction hole 212 with a round hole can provide sufficient suction while reducing the pressure on the patient's oral soft tissue.

[0033] In an optional embodiment, a sponge layer covering the first saliva suction hole 122 is provided at the front end of the first-stage suction head 100. The airflow and water pass through the sponge layer and then enter the first-stage suction head 100 for suction, thereby preventing the rapid airflow from vibrating in the pipeline, thereby reducing noise and reducing the risk of pipeline blockage.

[0034] In an optional embodiment, if Figure 2 As shown, the inner surface and / or outer surface of the second end cap 210 is provided with a plurality of reinforcing ribs 213 arranged around the central hole 211. The design of the reinforcing ribs 213 not only enhances the structural strength of the second end cap 210, making it less likely to deform during long-term use, but also improves the overall stability of the saliva suction tube.

[0035] In an optional embodiment, the rear end aperture of the secondary suction head 200 is larger than the front end outer diameter of the primary suction head 100 and smaller than the diameter of the outer retaining ring 130. This design enables the secondary suction head 200 to be securely sleeved on the primary suction head 100.

[0036] In an optional embodiment, if Figure 3 As shown, the fixing screw 220 is a large head screw, and a semi-cylindrical handle paddle 221 is provided at the large head end of the fixing screw 220, so that the doctor can more easily rotate and fix the fixing screw 220 during the operation. The design of the handle paddle 221 not only increases the grip comfort of the fixing screw 220, but also improves the convenience and efficiency of the operation.

[0037] In actual use, the doctor can adjust the length of the secondary suction head 200 by rotating the fixing screw 220 according to the specific conditions and needs of the patient. When facing patients with mandibular edentulism or severe edentulism, the length of the secondary suction head 200 can be appropriately shortened to avoid sucking oral soft tissue and affecting work efficiency. When facing patients with hypertrophic tongue, the length of the secondary suction head 200 can be appropriately extended to improve the saliva suction effect and reduce the patient's discomfort.

[0038] In addition, in order to further improve the patient's medical experience, the utility model also sets a sponge layer at the front end of the primary suction head 100. This layer of sponge can not only reduce the vibration and noise generated by the airflow in the pipeline, but also filter out some larger particles and reduce the risk of pipeline blockage. At the same time, the softness of the sponge can further reduce the stimulation to the patient's oral soft tissue.

[0039] In summary, the adjustable non-invasive oral saliva suction tube provided by the utility model effectively solves the problems that are easy to occur in the use of traditional saliva suction tubes through unique design and optimized material selection, and improves the patient's medical experience and the doctor's work efficiency. At the same time, the utility model also has the advantages of simple structure, convenient operation, safety and reliability, and is suitable for wide promotion and use in the field of oral medicine.
