Description

Special autogiration of deciduous teeth pulls out broach

Technical Field

The utility model relates to the technical field of oral medical instruments, in particular to an automatic rotating broach special for deciduous teeth.

Background

Pulpitis and periapical inflammation are common diseases in children's stomatology, and are usually caused by degeneration and necrosis of pulp tissues in root canals due to bacterial infection. The common clinical treatment method is root canal treatment, and an important step in the root canal treatment operation is marrow extraction.

The basic pith extraction procedure is as follows: the broach is inserted into the root canal to about two thirds of the depth, and the broach is rotated gently to wind the root canal marrow on the broach and then withdrawn. However, for dental pulp with chronic inflammation, tissues are relatively bad and fragile, the dental pulp is difficult to be completely extracted by using a common pulp extracting needle, incomplete pulp which is not completely extracted is easy to cause pain of teeth, and the next treatment effect is influenced.

The patent with the publication number of CN201888852U discloses a novel short dental broach with a handle, which comprises a broach front part and a broach rear part, wherein the broach front part is a conical thin needle, the surface of the thin needle is provided with a barb for extracting pulp, the broach rear part is provided with a handle, the device is very convenient for a dentist to operate, but the device is a broach, which is difficult to extract clean pulp for deciduous anterior teeth and deciduous molar teeth with thick and big root canals and brings inconvenience to clinical operation, therefore, the special automatic rotary broach for deciduous teeth is provided.
