The fang moving device in the invention has a simple construction, is convenient for use, can remove fangs fast at a time, leaves a small wound in operation, and enables patients to suffer little pain.

Description

technical field [0001] The invention relates to a medical device for dental operations, in particular to a tooth root extraction device. Background technique [0002] Teeth are easily broken during trauma or tooth extraction. In principle, all kinds of broken roots should be taken out at one time during tooth extraction. The extraction of a broken tooth root is relatively complicated. So far, the commonly used methods in clinical practice mainly include root forceps extraction, root extraction of teeth, and flap bone removal. Using traditional methods and instruments to deal with residual tooth roots is often traumatic and takes a long time, and it is easy to cause intraoperative and postoperative complications, the effect is not ideal, and unnecessary pain is brought to the patient. Contents of the invention [0003] The object of the present invention is to provide a tooth root extraction device with simple structure, convenient use, complete removal of residual tooth r...
