The invention relates to a dental root file, in which a cavity is opened in the center of the file body, and a through hole connecting the cavity is opened on the outer wall of the file body. The radius of the through hole decreases gradually from the outer wall of the file body to the inner wall of the file body. The through hole is a circular platform hole, and the large radius of the circular platform hole is outward. Then a circular edge is formed at the corresponding place of the through hole on the file body, and the edge is located on the inner wall of the file body and enters the file body. After entering the root canal, the dental nerve enters the cavity through the through-hole, rotates the file body and cuts the dental nerve at the edge, which reduces the patient's pain; the outer surface of the file body is smooth, when the file body is pulled out, the resistance of the file body is small, it is convenient to pull out, and the file body will not pull the dental nerve, thus alleviating the patient's pain; the cavity body penetrates the handle and the file body, and can be on the handle. Connect the sterilizing solution tube and put the sterilizing solution into the cavity. The sterilizing solution can wash the cut dental nerve out of the root canal and press the root canal thoroughly. The cleaning efficiency of the root files is high.

牙根锉
本专利技术涉及医疗器械
,尤其是涉及一种牙根锉。
技术介绍
根管治疗是目前治疗各种牙髓炎、牙髓坏死、坏疽、牙齿折断等疾病比较理想和成熟的治疗方法。其主要过程是使用根管锉对病变根管内部和根管壁进行彻底清理,去处牙神经,并塑造出完整、光滑的根管内腔,然后在已成型的根管内填充其他材料,如牙胶尖等,以达到根管修复和治疗的目的。根管锉是用于根管内侧壁锉光,使之成形或拔除根管内残髓,去除碎屑的重要根管治疗器械之一。专利号为CN200620089849.1的中国专利《牙根锉》公开了牙根锉的聚具体结构为:包括塑料或木制的把手,在把手一端固定设有螺旋状的金属锉体,金属锉体采用NiTi记忆合金制成螺旋针状。金属锉体呈螺旋针状的牙根锉在使用时,靠针状的金属锉体将牙根管内的牙神经勾住,在向外拉出金属锉体时,将牙神经拉出,这种直接将牙神经拉出的方法,病患需承受的疼痛较大,病患的生理和心里负担较重,且在拉出牙神经的过程中,牙神经容易脱钩或断裂,金属锉体拉出后,仅带出少量的牙神经,牙根锉的使用效率较低,病患的疼痛时间较长。
