Description

Technical Field

[0001] This utility model relates to orthodontic treatment, and in particular to a modified saliva suction tube, belonging to the field of oral medical device technology. Background Technology

[0002] In clinical orthodontic treatment, bracket bonding is a crucial procedure that directly impacts the outcome. During the bonding process, the dentist uses an etching agent to treat the tooth surface to enhance the bond strength between the bracket and the tooth. Timely and effective removal of excess etching agent is essential; otherwise, residual etching agent may damage the gum tissue or affect the bonding result.

[0003] Publication number CN208926661U discloses an improved saliva suction tube, which includes a connecting tube and a working tube; the working tube is connected to the connecting tube; the working tube is flexible; the working tube includes an inner saliva suction tube and an outer saliva suction tube, the outer saliva suction tube covering the inner saliva suction tube, and the top end of the outer saliva suction tube has a mesh structure; the diameter of the top end of the outer saliva suction tube is larger than the top end diameter of the inner saliva suction tube. Furthermore, the working tube of the saliva suction tube is made of transparent material and soft plastic, can be bent freely as needed, and is for single use, ensuring the hygienic quality of the device. Based on the above information and commercially available saliva suction tubes, it can be seen that the length of commonly used surgical saliva suction tubes in clinical practice is usually 15-20 cm or even longer. These types of saliva suction tubes have significant shortcomings in delicate operations such as bracket bonding. Firstly, the longer tube body has poor flexibility when operating in the oral cavity and can easily interfere with the doctor's field of vision. Secondly, the excessively long tube body requires maintaining hand stability, increasing the burden on the hand. Thirdly, the suction port of conventional saliva suction tubes is not designed with a mechanism to intercept tooth fragments, which may cause tooth fragments to enter the saliva suction tube or the machine connected to it, thus requiring improvement.

[0004] Therefore, an improved saliva suction tube is proposed. Utility Model Content

[0005] In view of this, the present invention provides an improved saliva suction tube to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial alternative.

[0006] The technical solution of this utility model is implemented as follows: an improved saliva suction tube includes a tube body, one end of which is connected to a saliva suction section, and the other end of which is connected to a connection interface. A saliva suction port is provided in the saliva suction section, and an annular groove is provided in the saliva suction section. An intercepting tube is inserted into the saliva suction section, one end of which is connected to a gasket, and an annular buckle is provided on the intercepting tube. An intercepting net is provided inside the intercepting tube.

[0007] More preferably, the saliva-suction opening is obliquely cut, and the angle between the oblique cut surface and the axis of the saliva-suction section is thirty degrees.

[0008] More preferably, the tube body has a variable diameter structure, and the diameter of the section near the saliva inlet is slightly smaller than that of the section near the connection interface.

[0009] More preferably, the tube body is provided with anti-slip texture and the tube body is provided with scale.

[0010] More preferably, the tube body is made of polyvinyl chloride and the gasket is made of silicone.

[0011] More preferably, the length of the tube is eight to twelve centimeters, and the aperture of the intercepting net is one millimeter.

[0012] The present invention has the following advantages due to the adoption of the above technical solution: I. In this utility model, the tube body adopts a variable diameter structure design, which can ensure stable suction at the suction port and avoid the impact of suction fluctuations on the efficiency of acid etching. At the same time, the tube body is made of polyvinyl chloride, which can withstand acid etching corrosion, reduce wear and tear caused by chemical damage, and extend the overall service life of the suction tube. In addition, the overall length of the suction tube is controlled at 8-12 cm. Compared with the traditional long tube structure, it can significantly improve the flexibility of bracket bonding operations, effectively avoid the obstruction and interference of the doctor's operating field of vision by the long tube body, and better adapt to the limited operating space in the oral cavity, meeting the needs of precise operation.

[0013] II. In this utility model, by setting a combination structure of annular groove, intercepting tube, gasket, annular buckle and intercepting net in the suction section, the cooperation of annular groove and annular buckle can realize the stable assembly of the intercepting components, and at the same time facilitate medical staff to quickly disassemble and replace them; the intercepting net can accurately intercept tooth debris, prevent debris from entering the tube with the acid etching agent and causing blockage, reduce operation interruption caused by tube blockage, and reduce equipment maintenance frequency.

[0018] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0019] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0020] like Figure 1-5 As shown, this utility model embodiment provides an improved saliva suction tube, including a tube body 1, one end of the tube body 1 is connected to a saliva suction section 2, the other end of the tube body 1 is connected to a connection interface 3, a saliva suction port 4 is provided in the saliva suction section 2, an annular groove 7 is provided in the saliva suction section 2, an interception tube 8 is inserted in the saliva suction section 2, a gasket 9 is connected to one end of the interception tube 8, an annular buckle 10 is provided on the interception tube 8, and an interception net 11 is provided inside the interception tube 8.

[0021] In one embodiment, the suction port 4 is obliquely cut, and the angle between the oblique cut and the axis of the suction section 2 is 30 degrees. This facilitates operation close to the tooth surface and improves the efficiency of acid etching agent removal.

[0022] In one embodiment, the tube body 1 has a variable diameter structure, and the section near the saliva inlet 4 has a slightly smaller diameter than the section near the connection interface 3. After the external suction device is activated, the variable diameter section near the saliva inlet 4 forms a stable suction force under the action of the tube body 1.

[0023] In one embodiment, the tube body 1 is provided with anti-slip texture 5 and scale 6. During operation, medical staff hold the tube body 1 to keep it stable by holding the anti-slip texture 5 area, adjust the position of the suction port 4 according to the scale 6, and cooperate with the doctor's acid etching operation to remove excess acid etching agent in a timely and accurate manner, ensuring the smooth progress of the bracket bonding operation.

[0024] In one embodiment, the tube body 1 is made of polyvinyl chloride (PVC), and the gasket 9 is made of silicone. PVC is highly corrosion-resistant and has a long service life, while the silicone gasket 9 is skin-friendly, soft, and avoids damage to the gums. The overall length of the suction tube is controlled at 8-12 cm. Compared to traditional long tube structures, this significantly improves the flexibility of bracket bonding operations, effectively avoids the long tube body 1 obstructing the doctor's field of vision, and is more suitable for the limited operating space in the oral cavity. In one embodiment, the length of the tube 1 is eight to twelve centimeters, and the aperture of the interceptor mesh 11 is one millimeter. When the mixture flows through the interceptor tube 8, the interceptor mesh 11 acts as an interceptor, blocking dental debris inside the interceptor tube 8 and preventing debris from entering the interior of the tube 1 and the connected suction device.

[0025] In operation, this invention works as follows: Before use, the intercepting tube 8 is inserted into the suction section 2. With the cooperation of the annular buckle 10 and the annular groove 7, the intercepting tube 8 is pushed until the gasket 9 is tightly fitted to the end face of the suction section 2, thus completing the assembly. At this time, the intercepting net 11 is located in the channel between the suction port 4 and the tube body 1. Next, the connecting interface 3 is connected to the external suction device. The medical staff holds the area of ​​the tube body 1 with anti-slip texture 5 and determines the insertion depth through the scale 6 on the tube body 1. According to the bracket bonding operation requirements, the angle of the suction port 4 is adjusted so that the suction port 4, which is cut at a 30-degree angle, is aligned with the area of ​​the tooth surface to be treated, preparing for the subsequent removal of the etching agent. After the external suction device is started, under the action of the variable diameter structure of the tube body 1, the narrow section near the suction port 4 forms a stable suction force, and the etching agent and any accompanying tooth debris are sucked into the suction port 4. When the mixture flows through the interception tube 8, the interception mesh 11 acts as an interceptor, blocking dental debris within the interception tube 8 and preventing it from entering the tube body 1 and the connected suction device, thus preventing blockage of the tube body 1 and damage to the device. Simultaneously, the PVC tube body 1 ensures that it will not be damaged by chemical reactions during suction, while the silicone gasket 9 effectively enhances the seal between the interception tube 8 and the suction section 2, preventing suction leakage from affecting suction efficiency.

[0026] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
