A slice-cut sand bar hand-held device

Abstract

The invention discloses a hand-held device for slice-cut sand bar, which comprises a main body, a rotating arm and a sand bar. The main body includes an upper plate, which is divided into a first plate and a second plate through slots, and a boss is arranged under the upper plate. A lower plate is installed under the boss, and the two ends of the lower plate are respectively fixed to the upper end of the handle. The mounting hole on the upper part of the handle is fixed with a rotating arm through a bearing set. The fixed post is covered with sand strips. The device is simple in structure, easy to operate, easy to adjust the strength and speed of slice cutting, avoids pain for patients, increases the area of ​​resin bonding, increases the bonding strength of adjacent teeth, and prepares for the subsequent contact bonding. The preparation work is easy, the sand bar is replaced and disinfected conveniently, and other diseases of the patient's gums are avoided.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary tools, in particular to a hand-held device for cutting sand bars. Background technique [0002] Food impaction refers to food wedged into the interdental space under the action of occlusal force. It is a common oral clinical disease, which is often accompanied by other oral diseases, and can cause clinical symptoms such as gum pain and bleeding. Food impaction will have a great impact on the life of patients. If it is not improved for a long time, it will further lead to dental caries, gingival recession, bad breath and other problems, and further lead to damage to adjacent teeth and surrounding periodontal tissue. Food impaction is usually clinically divided into horizontal type, vertical type and mixed type; among them, the vertical type has the highest proportion of food impaction. Vertical food impaction means that food is embedded into the interdental space vertically from the occl...

AI Technical Summary

Problems solved by technology

[0003] At present, there are many methods for treating food impaction. At present, the common tools used by people to remove food impaction are toothpicks and dental floss: due to the shape limitation, the working end of the toothpick cannot completely enter the interdental gap, and in most cases it can only remove the central incision. The food impaction between teeth, lateral incisors, canines and some premolars cannot be removed, and because the working end of the toothpick is relatively sharp, it is easy to hurt the gums, especially the gums when picking teeth Nipples, leading to gingival recession, and when the toothpick penetrates into the interdental space with a large thrust, it will cause tooth loosening; and the more commonly used medical methods include ring forming contact bonding, prosthetic restoration, orthodontics, filling treatment, tooth extraction, etc.
