Flexible jig device for root canal file grinding

Abstract

The invention provides a flexible jig device for root canal file grinding, and belongs to the technical field of root canal file grinding machining. The flexible jig device comprises an L-shaped swingarm, a swing arm rotating pin, a sliding block and a ball head connecting base, protruding supporting tables are arranged at the two ends of a support, material holes are formed in the supporting tables, the L-shaped swing arm is hinged to the support through the swing arm rotating pin, a V-shaped bearing groove is formed in the upper side of one end of the L-shaped swing arm, and a ball head groove is formed in the other end of the L-shaped swing arm. A lead screw is rotatably arranged on two lead screw supports, the sliding block is slidably arranged on a sliding rail, the lead screw is inlead screw connection with a lead screw nut, the ball head connecting base is installed at the upper end of the sliding block, the ball head connecting base comprises a ball head portion and a supporting rod portion, and the ball head portion of the ball head connecting base is embedded into the ball head groove of the L-shaped swing arm. Real-time supporting of a root canal file is achieved through the V-shaped bearing groove in the L-shaped swing arm, the root canal file can be effectively prevented from deforming and even being broken in the grinding machining process, and the reliability and stability of grinding machining of the root canal file are greatly improved.

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
