Description

A oscillation and washing integrated device for root canal therapy

Technical Field

The utility model relates to an oscillation and flushing integrated device for root canal treatment, and belongs to the technical field of root canal treatment.

Background

The oscillating irrigators for root canal therapy currently on the market have the following disadvantages: firstly, the root canal swinging and washing process needs to be completed in three steps: 1) injecting solution through the syringe needle after the tooth is opened; 2) oscillating through an oscillation washer; 3) the solution was injected through a syringe for rinsing. The above process needs to be repeated several times. If the broken debris is not washed immediately after being vibrated and stirred, the broken debris can continue to settle due to gravity, if the broken debris is stuck in the root tip, the broken debris is difficult to remove during the next washing, root canal inflammation is easy to cause, in serious cases, the failure of root canal treatment is caused, and teeth have to be pulled out; secondly, the process of washing the root canal by oscillation needs to be finished by a plurality of steps, and the oscillation and the washing are separated, so that the medical care feels inconvenient and fussy during the operation. Thirdly, the volume of the injector is limited, if more solution is used, the injector needs to be changed into a large one, so that the operation in the oral cavity is inconvenient, and the patient has too much solution in the mouth and is choked, thereby causing medical accidents; repeated drawing of the solution through the syringe can allow the impurities to be accessed in the pulp chamber for too long a period of time.
