Description

Tooth root canal treatment device Technical Field The invention belongs to the field of medical equipment, and particularly relates to a tooth root canal treatment device. Background The root canal treatment operation is the most common, effective and perfected method for treating dental pulp diseases and periapical diseases, and the current root canal treatment operation steps mainly comprise pulp opening, root canal preparation, root canal disinfection and root canal filling. Among them, root canal preparation has been a major problem that plagues clinicians. At present, a manual method is mainly adopted in clinic to complete the whole tooth root canal treatment process, in a narrow oral cavity working space, a doctor performs root canal preparation by manually rolling and lifting or using a rotary nickel titanium instrument, the tooth generally has a plurality of root canals, and the time for completing root canal preparation of the whole tooth is long. The doctor needs to keep a fixed posture for a long time to perform the operation during the root canal treatment, brings great working strength to the treating doctor, is easy to cause fatigue of the doctor, causes diseases such as cervical vertebra and lumbar vertebra and the like, and brings pain to the patient. Root canal preparation is seriously dependent on experience and operation level of doctors, medical accidents such as root canal file fracture, lateral puncture and the like can be caused by careless operation, and incomplete root canal preparation can be caused by doctors with insufficient experience, so that secondary infection is caused. In the prior art, a dental root canal treatment device is generally arranged on a multi-axis mechanical arm or a three-dimensional moving platform, in the actual use process, the dental root canal treatment device is sent into the oral cavity of a patient by means of the multi-axis mechanical arm or the three-dimensional moving platform, and then positioning treatment is carried out on a treatment place, so that a problem is generated, if the moving speed of the multi-axis mechanical arm or the three-dimensional moving platform in the adjustment process is too slow, the external moving positioning is very time-consuming, the integral efficiency is low, and if the moving speed of the multi-axis mechanical arm or the three-dimensional moving platform in the adjustment process is too fast, high-precision fine adjustment is difficult to be carried out in the oral cavity of the patient, and the fine adjustment requirement of the oral cavity of the patient can be met by only three fine adjustment actions of pitching, advancing and retreating and lifting, so that the position and posture of a root canal treatment end in the prior art can be finely adjusted, and the root canal file in the oral cavity of the patient can be met, and the aim of quick rough adjustment and fine adjustment of the root canal file in the treatment process is fulfilled.
