Endodontic (root canal therapy, RCT) is currently accepted as the most effective and common method of treating periapical disease of the pulp root, retaining natural teeth. The teeth are positioned in the oral cavity saliva environment, besides being moist, the saliva also contains a large amount of microorganisms, so that the teeth in the operation area are effectively isolated from the oral cavity environment in the root canal treatment process, and the prevention of the contamination of the saliva and the microorganisms to the operation area is a technical key for successful root canal treatment.
The existing rubber barrier isolation method uses a metal fixing clamp to mechanically clamp and hold the high-point gum square outside the tooth cheek, tongue, face and body for retention. For example, the Chinese patent application No. 2021230370357, the application day 2021-12-06 and the name of a rubber barrier fixing clamp disclose a rubber barrier fixing clamp, which comprises an elastic arc bow, wherein a first clamping arm and a second clamping arm are respectively arranged at two free ends of the elastic arc bow, a first beak-shaped clamping part is arranged at the inner side of the first clamping arm, a second beak-shaped clamping part corresponding to the first beak-shaped clamping part is arranged at the inner side of the second clamping arm, an extending first long arm is arranged on the first clamping arm, an extending second long arm is arranged on the second clamping arm, and the first long arm and the second long arm gradually shrink along the extending direction; the elastic arc provides elastic force to enable the first beak-shaped clamping part and the second beak-shaped clamping part to clamp and be fixed on the proximal teeth, and simultaneously the first long arm and the second long arm clamp a plurality of tooth gum parts adjacent to the proximal teeth or tooth gum parts at the distal ends under the action of the elastic force provided by the elastic arc.
