Abstract
Description
Technical Field
[0001] This utility model relates to the field of dental cleaning equipment technology, and in particular to a dental subgingival spray nozzle. Background Technology
[0002] Currently, in dentistry, compressed gas (usually air) is typically used to propel abrasive powder onto the tooth surface, where it mixes with a liquid medium (usually water) to clean the tooth surface and subgingival periodontal pockets, thus preventing periodontal inflammation and disease. During air polishing, the air and liquid medium have independent channels inside the nozzle and spray head, preventing interference between them and avoiding the mixing of airborne abrasive powder with the liquid medium that could cause blockage.
[0003] There are two main ways to connect and install subgingival nozzles on the market: 1. The subgingival nozzle and the subgingival tip are fixedly connected by a third component other than the two. This method increases material costs and is complicated to install. 2. The subgingival nozzle and the subgingival tip are directly connected. In this method, the angle of the subgingival tip is fixed after it is installed, which cannot meet the needs of various angles in clinical practice. Utility Model Content
[0004] The purpose of this invention is to provide a dental subgingival nozzle that solves the problems of cumbersome connection and installation, fixed angle, and inability to flexibly adapt to clinical needs in existing subgingival nozzles.
[0005] To achieve the above objectives, this utility model provides a dental subgingival spray nozzle, comprising a spray head body, a spray head air tube, and a nozzle; the spray head body is detachably connected to the nozzle and is located on one side of the spray head body; the spray head air tube communicates with the spray head body and is located on the side of the spray head body closer to the nozzle; the spray head body includes a first groove and a second groove, the first groove being located on one side of the spray head body, and the second groove being located on the side of the first groove away from the nozzle; the nozzle has a first boss and a second boss, the second boss being located on the side of the nozzle closer to the spray head body, and the first boss being located on the side of the second boss away from the spray head body.
[0006] The nozzle body has a first channel air pipe, which is connected to the nozzle air pipe and located on one side of the nozzle air pipe. The nozzle has a second channel air pipe, which is located inside the nozzle.
[0007] The nozzle body has a first channel water pipe located on one side of the nozzle air pipe, and the nozzle has a second channel water pipe located inside the nozzle.
[0008] The nozzle body has a first guide groove and a second guide groove, the first guide groove being located on the nozzle body and the second guide groove being located on the side of the nozzle body closer to the first guide groove.
[0009] The dental subgingival nozzle also includes a friction ring, which is fixedly connected to the nozzle and located on the side of the nozzle closer to the nozzle body.
[0010] This invention relates to a dental subgingival spray nozzle. During installation, the nozzle body and the nozzle are aligned. The nozzle body and the nozzle are connected via a first groove and a first boss ring, and a second groove and a second boss ring, completing the installation. Compared to the traditional method of connection via a third component, this reduces material costs and installation complexity. Furthermore, the nozzle body and the nozzle can rotate at any angle, facilitating cleaning of hard-to-reach areas such as interdental spaces and periodontal pockets, enabling comprehensive treatment. The nozzle air tube connects the nozzle body and the nozzle, allowing the nozzle to use compressed gas to spray therapeutic powder and liquid media onto the tooth surface. This solves the problems of cumbersome connection and installation, fixed angle, and inflexible application to clinical needs in existing subgingival spray nozzles. Attached Figure Description
