Handheld root canal file device

Abstract

The invention relates to a handheld root canal file device for dental filling. The handheld root canal file device comprises a root canal file assembly, wherein the root canal file assembly is connected with a handheld root canal file handle; in addition, the root canal file assembly is rotationally connected with the handheld root canal file handle. The operation space required by an operator isreduced; the problem caused by conflict between the narrow space in the oral cavity and the relative big operation space required by the operator in the prior art is solved. The technical scheme thatthe root canal file assembly is rotationally connected with the handheld root canal file handle is utilized; the operation space required by the operator is reduced; in the process, the direction regulation of the handheld root canal file device can be completed by only triggering the root canal file assembly no matter in the operation of inspection and preparation for molar remote middle root canals or the inspection and preparation for molar near and middle root canals; during the root canal file triggering, the long handheld root canal file handle cannot move in a following way, so that theoperation space required by the operator is reduced, thereby the space in the oral cavity can meet the operations of unobstructed root canal inspection and preparation and the like by the operator.

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 canal that is far away from the hand root canal file (equivalent to the rotation center) The operating angle of the file handle will be multiplied and changed, resulting in a large operating space required by the operator (by image 3 From the display of the left and right parts, the angle changes greatly, and a relatively large operating space is required to complete), and the human mouth is narrow, which cannot provide the large space required for using the micro-reamer. The exploration of the mesial root canal can only rely on the operator's feeling, so that the exploration and preparation
