Description

Technical Field

[0001] The utility model relates to the technical field of turning needles, in particular to a turning needle for removing a fractured implant base. Background Art

[0002] A dental bur is a needle-shaped tool mainly used for dental surgery and diagnosis. It is usually made of stainless steel and has a sharp double-sided blade or needle. It can be used for sampling, puncture, cutting, suturing and other operations. The dental bur is in the shape of a short straight stick of equal thickness. One end is sharp or blunt for precise positioning, and the other end is connected to the handle through a shaft.

[0003] In conventional dental surgery, the dental needle, needle clamp and rotating shaft are usually connected by threaded connection. Specifically, the needle clamp usually has a threaded opening, and the rotating shaft has another threaded opening that matches it. In this case, the needle can be installed on the rotating shaft by tightening the threaded openings of the needle clamp and the rotating shaft with a suitable tool, thereby completing the connection between the dental needle, needle clamp and rotating shaft. However, the size of the needle and needle clamp is very small, which is not convenient for rotation, making installation and disassembly very cumbersome. Utility Model Content
