AI Technical Summary

Technical Problem

Existing protective devices for clinical dental preparation are difficult to maintain a proper mouth-opening position for extended periods in children's mouths, affecting children's comfort and the continuity of the surgeon's operation, and lack a design adapted to children's oral tolerance.

Method used

The upper and lower tooth support blocks are hinged together in an arc-shaped shell shape, combined with an elastic expansion component and an oral cavity opening adjustment component. The elastic expansion maintains the oral cavity expansion state and can adjust the oral cavity opening to suit the characteristics of children's oral cavity.

Benefits of technology

It reduces oral muscle fatigue in children, improves tolerance and cooperation, reduces the probability of tissue damage, ensures the continuity and precision of surgical procedures, and enhances children's comfort and safety.

Abstract

The present application relates to the technical field of oral medical instruments, in particular to a special protective device for clinical tooth preparation of children's oral cavity, comprising an arc-shaped shell-shaped upper tooth support block and a lower tooth support block, the upper tooth support block and the lower tooth support block are hingedly connected, an elastic expansion assembly is arranged at the hinge connection of the upper tooth support block and the lower tooth support block, and the elastic expansion assembly is used for generating elastic expansion prestress acting on the upper tooth support block and the lower tooth support block; the hinge connection of the lower tooth support block and the lower tooth support block is also provided with an oral cavity opening degree adjusting assembly, and the oral cavity opening degree adjusting assembly is used for adjusting the maximum relative swing angle of the lower tooth support block and the lower tooth support block around the hinge connection; the present application maintains the oral cavity expansion state through the arc-shaped shell-shaped upper tooth support block and the lower tooth support block which are hingedly connected, cooperates with the elastic expansion assembly, and adjusts the oral cavity opening degree, so that the technical defects that the existing mouth opener is difficult to adapt to the tolerance of children's oral cavity are solved.
