Description

Moisture absorption device in root canal

technical field

The utility model relates to the technical field of oral medical instruments, in particular to a moisture-absorbing device in a root canal.

Background technique

Apical surgery is a surgical method to promote the healing of periapical disease by scraping the periapical diseased tissue, removing the infected root tip, and sealing the root canal system tightly. One of the key steps in apical surgery is root canal backfilling. Before root canal backfilling, it is necessary to thoroughly dry the apical 3mm root canal in the operation area. Since the direction of the area that needs to be dried is perpendicular to the direction of the area that can be directly reached by the instrument, and the operation area is wet and bleeding, it is difficult to dry, so it is necessary to achieve the complete drying of the target area through a simple and convenient method.

At present, the most commonly used method when drying the dental operation area is to bend the tip of the moisture-absorbing paper at 90° and place it on the target area for drying. However, due to the humidity of the operation area, it is often stained by surrounding tissue fluid and blood before reaching the position that needs to be dried. Wet, and repeated operations are required to dry thoroughly, which is time-consuming and laborious; Chinese patent CN214434569U discloses a paper tip conveyor for apical surgery, which puts the paper tip from the end of the delivery tube so that the paper tip can be inserted The head flows out and enters the notch to realize the absorption and removal of the liquid in the notch. The angle of the fixed end can be adjusted at will to adapt to notches of different positions and angles. However, the method mentioned in this device has pipeline bending, and it is difficult for the moisture-absorbing paper tip to pass through the curved part. The gravity of the moisture-absorbing paper tip is used to make the paper tip enter the root canal. For some teeth, such as the lower teeth, the direction of transporting the paper tip It is opposite to the direction of gravity, which is difficult to achieve, and it is difficult to completely dry the operation area with a moisture-absorbing paper tip. Repeated operations are required, which is time-consuming and laborious, and it is difficult to solve the problem of paper tip being contaminated by the operation area.
