Description

A negative pressure device for root canal and sinus irrigation

technical field

The utility model relates to the field of negative pressure flushing devices, in particular to a negative pressure device for root canal and sinus flushing.

Background technique

In dental clinics, teeth need root canal treatment due to pulp disease, periapical disease and other reasons. Root canal treatment is divided into three steps: root canal preparation, root canal disinfection and root canal filling. In the above steps, root canal irrigation runs through the whole process to further clean up the necrotic pulp tissue and infected substances in the root canal. At present, the existing chemical flushing, ultrasonic cleaning and laser disinfection can remove the infected substances in the root canal well, but there are still some problems. discomfort or pain; and for sinus tracts with refractory apical periodontitis that have not healed for a long time, the existing methods cannot effectively clean up the infected substances in the sinus tracts. The modern point of view is to try not to inject calcium hydroxide and other disinfectants into the sinuses Anti-inflammation of the sinus tract to avoid protracted healing of the sinus tract, which requires us to remove the infectious substances in the sinus tract through irrigation. Therefore, we propose a negative pressure device for root canal and sinus irrigation. This device can place the negative pressure suction head on the upper 1/3 of the root canal, and when the irrigator penetrates into the middle and lower 1/3 of the root canal When flushing, the negative pressure head will suck out the flushing agent and infectious substances in time, and it is not easy to flush the infectious substances out of the apical foramen. The suction head can also be placed at the opening of the sinus tract. When the root canal is flushed, the flushing medicine will enter the sinus tract due to negative pressure suction, and the infected substances in the sinus tract will be thoroughly cleaned, which is more conducive to the healing of the sinus tract.
