Anti-slipping-falling positioner of tooth extraction knife and method of using anti-slipping-falling positioner

Abstract

The invention relates to an anti-slipping-falling positioner of a tooth extraction knife and a method of using the anti-slipping-falling positioner. The anti-slipping-falling positioner of the tooth extraction knife comprises a fixed protective sleeve and a connecting rod, wherein the fixed protective sleeve is provided with a cavity for accommodating and fixing a tooth extraction knife handle; and the connecting rod is arranged at the bottom of the fixed protective sleeve and is fixedly connected with the fixed protective sleeve, and a positioning pin is arranged at the end part of the connecting rod. When tooth extraction is performed, the positioning pin is fixed in the center of an occlusal surface of a tooth which is expected to be extracted, and then the tooth extraction knife is used for drawing an arc by taking the connecting rod as a shaft and taking the positioning pin as a circle center to cut the periodontal ligaments and separate the tooth root and the alveolar bone.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an anti-slip positioner for dental extraction knives and a method for using the same for preventing dental extraction knives from slipping off. Background technique [0002] Minimally invasive tooth extraction has gradually become a routine method of tooth extraction, which avoids percussion and other malignant stimuli during tooth extraction, so it has been accepted by most patients and stomatologists. In minimally invasive tooth extraction, the use of tooth extraction knife has played an irreplaceable role. [0003] The sharp edge of the dental extraction knife is good for cutting the periodontal ligament, compressing the alveolar bone and making it gap open. If the extraction knife is used properly, the tooth can be dislocated on the basis of cutting and tearing the periodontal ligament, and the alveolar bone can be damaged to a minimum, and the relatively complete structure of...

AI Technical Summary

Problems solved by technology

In the process of using the tooth extraction knife, if you do not hold the tooth extraction knife firmly or use improper force on the tooth extraction knife, it may cause the tooth extraction knife to slip off

However, the blade of the tooth extraction knife is sharp, and it is very easy to accidentally injure the surrounding soft tissues after the tooth extraction knife slips off. In severe cases, it may be fatal due to cutting blood vessels and nerves, or cause irreversible damage.
