Embodiment Construction

[0015] As shown in the figure, a minimally invasive universal apex lifter disclosed by the present invention includes a handle 1, a lifter blade 5, and a lifter seat 3. The front end 51 of the lifter blade 5 is in the shape of an ultra-thin spoon, which can be selected and replaced according to the needs of root apex extraction surgery. 2-4mm different sizes of jigsaw, the jerk 3 is provided with a through installation hole 4, the rear end 53 of the jerk 5 is set in the installation hole 4, and the top of the handle 1 is provided with a connecting rod 2 obliquely, for convenience The straight blade stretches into the oral cavity and is convenient for pressing. The angle between the center line of the connecting rod and the center line of the handle is 30 degrees. The outer surface of the rear end 53 is a polygon 52. For the polygon 52 at the rear end of the jacking blade, the mounting hole 4 is designed to be a hole matched with the polygon, so that the compression of the top o...

Abstract

The invention discloses a minimally invasive universal apex lifter, which includes a handle, a connecting rod, and a lifter blade. There is a mounting hole, the rear end of the lifting blade is penetrated in the mounting hole, the top of the handle is provided with a connecting rod, the lifting seat is threadedly connected with the connecting rod, and the top of the connecting rod is tightly pressed against the rear of the lifting blade. end. By adopting the above-mentioned technical scheme, the universal rotation of the lifting edge can be realized, so as to realize the change of the direction of the lifting edge, and it is easy to use and labor-saving to lift and remove the residual root tip of the tooth.

Description

technical field [0001] The invention relates to a dental medical instrument, in particular to a minimally invasive universal apex lifter. Background technique [0002] Apex lifter is one of the commonly used dental medical devices, it is mainly used to wedge into the gap between the tooth root and the alveolar bone during tooth extraction, and loosen the tooth so as to facilitate tooth extraction. In the case of bent root, hypertrophy of the root end, pathological adhesion between the root and the alveolar bone, etc., it is more difficult to extract the tooth when the connection between the broken root part and the periradicular tissue is basically not separated. [0003] The current apex elevating blade narrow beak is broken into a sharp protrusion, which is in point contact when wedged into the root and periodontal tissue, and is prone to secondary fragmentation during apex extraction. Minimally Invasive Universal Root Tip Raising Blade is narrow and thin, and the blade i...
