A root canal file grinding flexible jig device

Abstract

The invention provides a root canal file grinding flexible fixture device, which belongs to the technical field of root canal file grinding. It includes an L-shaped swing arm, a swing arm rotation pin, a sliding block, and a ball joint seat. The two ends of the bracket are provided with raised support tables, and the support tables are provided with material holes. The L-shaped swing arm is hinged on the swing arm through the swing arm rotation pin. On the bracket, the upper side of one end of the L-shaped swing arm is provided with a V-shaped support groove, the other end of the L-shaped swing arm is provided with a ball head groove, the screw rod can be rotated and arranged on the two screw rod supports, and the slider can slide Set on the slide rail, the screw is connected with the screw nut, and the ball joint seat is installed on the upper end of the slider. The ball joint seat includes a ball head and a support rod, and the ball head of the ball joint seat is embedded in the L The ball head groove of the swing arm. The invention realizes the real-time support of the root canal file through the V-shaped support groove on the L-shaped swing arm, can limit the deformation or even breakage of the root canal file during the grinding process, and greatly improves the grinding process of the root canal file. reliability and stability.

Description

technical field [0001] The invention relates to the technical field of root canal file grinding, in particular to a flexible fixture device for root canal file grinding. Background technique [0002] Root canal therapy, also known as endodontics, is a procedure in dentistry for the treatment of necrotic pulp and infected roots, which preserves the tooth and is therefore complementary to tooth extraction. Root canal treatment requires a set of fine and flexible root canal files to clean the root canal and shape the root canal. The dentist rotates and lifts the root canal through a hand file or a machine file connected to a motor. , during the operation of rotating and pulling the root canal, the root canal file cuts off the lesion in the path while going deep into the root canal. The root canal file is one-piece, generally made by grinding, generally divided into two parts, one part is the handle, the other part is the blade, the blade is in the shape of a cone, and there is...

AI Technical Summary

Problems solved by technology

However, because the root canal file is very thin, it only depends on the two ends for positioning and support, so it is easy to deform or even break during the grinding process.

At present, no company in the market can complete the processing of needle files with such high precision requirements, and there is no related processing equipment that adopts a real-time support structure
