Curved handpiece for dental root canal treatment

Abstract

The invention discloses a curved handpiece for dental root canal treatment. According to the curved handpiece for dental root canal treatment, an overall scheme of the dental curved handpiece which isconductive inside, insulated in surface, compact in structure, small in height and size and convenient to maintain is formed for the first time in the industry; the curved handpiece can accurately, safely and stably realize a dental root canal length measuring function, further realizes a stable two-in-one function of combining root canal preparation and dental root canal length measurement, is compact in integral structure, provides a good visual field, reduces the risk of instrument separation or preparation step generation in the operation process of doctors, and greatly guarantees the safety improvement. According to the scheme, disassembling, maintenance and cleaning are facilitated, the risk of cross infection is reduced, the use safety and convenience effects of the device are further improved, and the curved handpiece has great market benefits.

Description

technical field [0001] The invention relates to the field of dental medical instruments, in particular to a contra-angle handpiece for dental root canal treatment. Background technique [0002] At present, there are many kinds of internal conductive structures (with different structures) of contra-angle handpieces for dental root canal treatment on the market, and there are also many insulation schemes for the outer surface. For the back cover of the handpiece that needs to be pressed to hold the root canal file, in order to achieve insulation At the same time, there are different structures for the purpose of controlling the height dimension to be smaller. Finally, for the overall structure of the dental contra-angle handpiece, under the premise of simultaneously realizing internal conduction plus surface insulation and reducing the height of the back cover of the handpiece (insulation is also required), the connection and fastening methods between the components are basica...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a contra-angle handpiece for dental root canal treatment, which aims to solve the problem of unstable electrical conductivity during operation, easy failure or complex structure and difficult maintenance of the contra-angle handpiece for dental root canal treatment in the prior art; The product is externally connected to the conductive structure, which leads to a large shape and poor vision, which increases the risk of equipment separation or preparation steps during the operation of the doctor, resulting in technical problems of low operational safety.
