Description

Technical Field

[0001] This invention relates to the field of root canal technology, and more particularly to a dental root canal clock lathe. Background Technology

[0002] Currently, in recent years, due to the maturity of root canal treatment techniques, more and more teeth with pulp and periapical diseases have been preserved. To restore the physiological shape and function of the tooth, post-core crown restorations are widely used. Dental post-cores are biomimetic instruments used in dental restorations, inserted into the patient's root canal to fix the artificial crown. Before installing a dental post-core, a pre-drilled hole needs to be made using a drill bit and drill shank. To prevent the drill bit from slipping during rotation, the concentricity accuracy of the drill shank's inner hole is crucial. Existing drilling equipment for dental post-cores has low concentricity and slow processing efficiency. Utility Model Content

[0003] In order to solve one or more technical problems existing in the prior art, the purpose of this application is to provide a dental root canal chord clock lathe that achieves high concentricity of drilling in the dental root canal post drill shank drilling equipment.

The other end of the inclined rod is hinged to the rectangular support sleeve.

[0009] Furthermore, a handle is provided at the top of the push rod.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] (1) When in use, the drive assembly drives the rotating shaft and the workpiece to rotate. The workpiece is the dental root canal post. During the rotation of the dental root canal post drill shank, the moving shaft is pushed. The moving shaft drives the drill bit to move.
