Gutta-percha filling structure and gutta-percha filling machine

Abstract

The embodiment of the invention provides a gutta-percha filling structure and a gutta-percha filling machine, and relates to the technical field of root canal therapy, and the gutta-percha filling structure comprises a handle fixing sleeve and a needle head fixing sleeve which are detachably connected; the heating tube is arranged in the handle fixing sleeve; the needle head assembly is arranged at one end, deviating from the handle fixing sleeve, of the needle head fixing sleeve in a penetrating manner, part of the needle head assembly is detachably accommodated in the heating tube, the needle head assembly is provided with a gutta-percha cavity and a hot glue channel, the calibers of the gutta-percha cavity are sequentially reduced, and the gutta-percha cavity is communicated with the hot glue channel; and the push rod can be partially accommodated in the heating tube and the gutta-percha cavity in a reciprocating manner and is used for pushing and propping the gutta-percha, so that the gutta-percha is introduced into the hot glue channel from the gutta-percha cavity. Therefore, when the gutta-percha is replaced, the gutta-percha cavity of the needle head assembly can be directly filled with the gutta-percha only by disassembling the needle head assembly and the needle head fixing sleeve together, contact between new gutta-percha and the handle is avoided, the infection risk of a patient is reduced, and the medical experience is improved.

Description

technical field [0001] The invention relates to the technical field of root canal treatment, in particular to a gutta-percha filling structure and a gutta-percha filling machine. Background technique [0002] A human tooth contains a pulp cavity, and 1-4 root canals, through which the dental nerve and the blood vessels that nourish the nerve are derived. When infection occurs in the dental pulp due to various conditions, it will cause functional damage to the tooth, and It can cause pain, jaw infection, and other ailments. Root canal therapy, also known as endodontic therapy, is a treatment method developed in recent years to protect affected teeth. Better therapeutic and protective effects. [0003] Root canal treatment includes several main treatment stages such as root canal preparation, disinfection and root canal filling. Root canal filling is to fill the enlarged root canal with medicinal materials after completion of root canal preparation and disinfection, so that ...

Problems solved by technology

[0004] The research of the inventors has found that the existing gutta-percha filling machine is usually provided with a mouthpiece connected to the gutta-percha cavity on the side of the handle to replace the gutta-percha, which makes it inconvenient to clean up the residual gutta-percha in the residual heating tube; in addition, due to The handle contains a lot of bacteria, so bacteria are inevitably attached to the filling port. During the process of replacing the gutta-percha, the new gutta-percha will also carry bacteria, which will eventually cause the gutta-percha to fill the patient's root canal , patients are susceptible to infection, poor medical experience
