Abstract

The invention discloses a residual tooth root extraction device. The residual tooth root extraction device comprises a cylindrical central column. A through hole is arranged on the central axis of thecentral column. The through hole comprises two vertical symmetrical conical holes. The small ends of the two conical holes are connected. Two opposite sides of the cylindrical surface of the centralcolumn are respectively provided with notches. One end of a support arm is located in the notch. A hinge shaft vertically passes through the two side walls of the notch and the end of the support armin the notch. The other end of the support arm is provided with a U-shaped fork port. An extraction rod comprises a screw and an extraction pin connected to the threaded tail end of the screw. The screw passes through a steel ball through the through hole, extends to one side of the fork port of the support arm and is connected to the steel ball through threads. The extraction pin is conical. Thelarge end of the extraction pin is connected to the threaded tail end of the screw. The conical surface of the extraction pin is provided with a helical cutting edge along the extraction pin length direction. The device can smoothly extract the residual tooth root from the gingiva.

Description

technical field [0001] The invention belongs to the technical field of tooth extraction, in particular to a device for removing tooth roots remaining in gums. Background technique [0002] Dentists often encounter patients with broken teeth. When the teeth are broken, the remaining roots on the gums are extremely difficult to extract, which causes great distress to the majority of patients, and also brings certain difficulties for doctors to extract the remaining roots.
