Handheld root canal file device

Abstract

A root canal file for tooth filling, comprising a root canal file assembly, the root canal file assembly is connected to a root canal file handle, and the root canal file assembly is rotatably connected to the root canal file handle. The invention reduces the operating space required by the operator, and solves the problems in the prior art caused by the contradiction between the narrow space in the oral cavity and the relatively large operating space required by the operator. The present invention adopts the technical feature of the rotary connection between the root canal file assembly and the root canal file handle, which reduces the operating space required by the operator. In this process, whether it is the exploration and preparation of the molar distal root canal, Or for the exploration and preparation of the mesial root canal of molars, the direction adjustment of the root canal file can be completed only by turning the root canal file assembly, and when the root canal file is pulled, the long handle of the root canal file will not No follow-up, thereby reducing the operating space required by the operator, so that the space in the oral cavity can already meet the operator's unobstructed root canal exploration and preparation operations.

Description

technical field [0001] The invention relates to a medical appliance, in particular to a root canal file as a root canal treatment tool. Background technique [0002] In the initial stage of root canal preparation, dentists often need to use 8#, 10# or 15# stainless steel hand files to explore the root canal opening and initially establish root canal access. However, for the premolars and molars located at the back of the oral cavity, due to the limitation of the patient's mouth opening and the obstruction of the operator's fingers, it is difficult for the operator to explore the root canal opening under direct vision or with the help of a mouth mirror. Surgeons often can only use stainless steel hand files to "blindly" detect the root canal orifice and prepare the root canal by relying on their own experience such as hand feeling and knowledge of the anatomical shape of the root canal system. [0003] The clinically used DG16 root canal probe has a single model, which can o...

Problems solved by technology

However, the tip of the micro-reamer is sharp and sharp, which is easily damaged and deformed or damaged. In addition, the angle of the working end of the micro-reamer is single, which is only convenient for the exploration and preparation of the molar distal root canal, but for the mesial root canal of the molar. The detection and preparation of the tube is extremely inconvenient, refer to image 3 , because the root canal file handle is fixedly connected with the hand root canal file, the root canal file handle rotates with the hand root canal file and changes the angle, and the root can
