Description

Technical Field

[0001] This utility model relates to the field of dental treatment equipment technology, specifically a dental implant handpiece. Background Technology

[0002] Currently, dental implant handpieces are used to hold rotating instruments such as burs, dental drills, and dental files, driving their movement to perform dental surgical operations such as cutting, grinding, shaving, and drilling. A dental implant handpiece includes an interconnected head, body, core assembly, and drive shaft assembly. The core assembly is located inside the head, and the drive shaft assembly is located inside the body with one end connected to the core assembly. The end of the drive shaft assembly away from the core assembly is connected to an electric motor. Power is transmitted between the core assembly and the drive shaft assembly through the meshing of several gears.

[0003] The conventional 20:1 implantable implant mobile phones generally use a closed and fixed structure for the head and drive shaft. After operation and use, the dirt and impurities generated are not easy to clean and maintain, which causes the internal core components and transmission components of the head to rust and be damaged, making them unusable. This greatly reduces the lifespan of the implantable implant mobile phone and increases the cost of hospitals or clinics.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.
