Combined interacanal fractured instrument extracting device

Abstract

The invention discloses a combined interacanal fractured instrument extracting device and relates to the field of medical apparatuses of the dental department. The combined interacanal fractured instrument extracting device comprises a hollow handheld rod, a needle connecting seat is connected to the lower end of the hollow handheld rod, a needle sleeve is arranged on the needle connecting seat, an inner core component is arranged in the hollow handheld rod and comprises an inner core fixing seat arranged in the hollow handheld rod, a push boosting slider capable of enabling the inner core component to reciprocate is arranged on the outer portion of the hollow handheld rod, the inner core fixing seat is provided with an inner core fixedly, and the inner core extends into the needle sleeve through the needle connecting seat and is capable of moving in the needle sleeve. The combined interacanal fractured instrument extracting device has the advantages that the combined interacanal fractured instrument extracting device is compact in structure, high in stability, humanized in design, convenient and labor saving to use and locally replaceable in case of damage to an extraction end, can be used by being viewed under a microscope directly and can serve as an MTA (mineral trioxide aggregrate) biological material delivery device.

Description

technical field [0001] The invention relates to the field of dental medical instruments, and more specifically relates to a combined root canal fractured instrument extraction device. Background technique [0002] Root canal therapy is currently the most effective method for treating pulp disease and periapical disease. Root canal therapy technology has developed into a complete theoretical system including rich content, substantial theory and fine operation techniques. Root canal treatment effectively reduces the microorganisms in the root canal through mechanical-chemical preparation, and through three-dimensional filling, so as to effectively promote the healing of periapical lesions. Its treatment process includes root canal preparation, root canal disinfection and root canal filling. The quality of root canal preparation is an important factor in determining the success of root canal treatment. Canal treatment, especially root canal preparation, uses a variety of inst...

AI Technical Summary

Problems solved by technology

[0004] The existing device for extracting broken instruments in the dental root canal has poor stability during the foreign body extraction process, and cannot be operated directly under a microscope, and the extraction end of the device for extracting broken instruments in the root canal has a small diameter and low strength, and is prone to fatigue after a period of use Damaged, resulting in unusable, most of the existing extraction devices for broken instruments in the dental root canal are integral structures, once the extraction end is damaged, it needs to be replaced as a whole instead of only the extraction section of the foreign body extractor, which increases the cost, so the design A combined root canal broken instrument removal device with simple structure and detachable foreign body extraction end is of great practical significance
