AI Technical Summary

Technical Problem

Anesthesiologists face the risk of loosened teeth falling out during endotracheal intubation. Current techniques for manual ligation are not secure, are cumbersome, and lack fixed attachment points, which increases the risk of tooth loss.

Method used

A tooth-prevention device for preventing tooth loss was designed, including a tooth fixation strap and a ligation gun. The device utilizes a ligation ring, a connecting rope, and an adhesive plate. The ligation gun achieves rapid fixation through its expansion rod and downward pressure rod structure. The ligation ring can be fitted onto the loose tooth and fixed by the adhesive plate to prevent accidental pulling.

Benefits of technology

It achieves quick and easy tooth fixation, avoids tooth loss caused by accidental traction, solves the problems of weak ligation and difficult removal in existing technologies, and improves the convenience and safety of operation.

Abstract

The utility model discloses a tooth anti-falling device which comprises a tooth fixing band, the tooth fixing band comprises a loop ligature ring, a connecting rope and a bonding piece, one end of the connecting rope is fixedly connected with the loop ligature ring, and the other end of the connecting rope is fixedly connected with the bonding piece; the ligation gun comprises a main body, a plurality of expansion rods and a pressing rod, one end of each expansion rod is connected into the main body through a torsion spring rotating shaft and attached to the pressing rod, the other end of each expansion rod is arranged outside the main body, one end of the pressing rod is arranged in the main body, and the other end of the pressing rod is connected with the other end of the expansion rod. And the plurality of expansion rods can move up and down relative to the main body so as to drive the plurality of expansion rods to rotate relative to the main body. Therefore, teeth can be rapidly fixed, operation and installation are convenient, and the situation that the teeth fall off due to mistaken traction can be effectively avoided.
