Description

Handle of tooth extraction tool

Technical Field

The utility model relates to the technical field of dental instruments, in particular to a tooth extraction tool handle.

Background

Dental extraction is one of the oldest and most common procedures in oral treatment. A set of conventional tooth extraction instruments and methods has long been developed, with a dental elevator being one of the most common and leading instruments. The traditional dental extraction elevator mainly adopts the lever principle and the wedge force principle to extract teeth. When the tooth is extracted, the alveolar ridge crest is taken as a fulcrum, the dental elevator is taken as a lever, and the tooth is extracted by using a larger tooth extraction force with smaller force, but the method is easy to cause the damage of the alveolar ridge and adjacent teeth and easily causes the breakage of the tooth root. In addition, the traditional dental elevator is not easy to insert into periodontal gaps due to the fact that the edges of the working head are thick, the force is often applied by means of hammering, the vibration performance is high, the fear of the psychology of a patient is easy to generate, and complications such as peripheral hard tissue damage and mandibular joint dislocation are often caused; and traditional tooth elevator that pulls out need borrow hammering thrust augmentation because material and design restriction, therefore its handle adopts metal material usually, generally is hexagonal handle or eight corners handle, and this kind of handle surface is smooth, and the edges and corners are clear, and antiskid nature is poor, has the uncomfortable sensation that the stalk rises to the hand, in addition because hexagonal or eight corners are equallyd divide unanimously equally, and no orientation face, during the operation of pulling out the tooth, hardly judge the head work sword end correct position, bring the inconvenience for the operation.
