Abstract

The embodiment of the invention discloses a telescopic and deformable gutta-percha tip cutter, which comprises a gutta-percha cutting part having a variable cutting surface, a rod piece connected to the side, away from the variable cross section, of the gutta-percha cross section. The gutta-percha cutter solves the problems that an existing gutta-percha cutter is not suitable for cutting off a gutta-percha point of a single root canal opening and cannot cut off the gutta-percha point according to the irregular shape of a root canal.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a retractable and deformable gutta-percha tip cutter. Background technique [0002] Pulp disease is a common disease in the Department of Stomatology. If it is not treated in time, it will affect people's diet, health and quality of life. In severe cases, it can cause a series of complications such as local infection, and even affect the health of the whole body. Root canal treatment is the first choice for this kind of disease clinically. It is to thoroughly clean the inflammatory pulp and necrotic tissue in the tooth pulp cavity and root canal, prepare and expand the formed root canal, and disinfect the root canal, and then tightly fill the root canal to remove the root canal. The infected contents in the tube and the adverse stimulation to the periapical tissue prevent the recurrence of infection and promote the healing of the apical lesion. [0003] At present, ...
