Technical Field

[0001] The utility model relates to the technical field of dental accessories, and more specifically to a cutting device for gutta-percha points. Background Art

[0002] The gutta-percha cutting device is a tool specially designed for use in dental surgery. Its main function is to accurately and effectively cut off the gutta-percha tip during dentistry. The gutta-percha tip is the most commonly used root canal filling material, used for the treatment of pulpitis, pulp necrosis, caries, various apical periodontitis, etc.

[0003] Currently, in dental surgery, common methods for cutting off gutta-percha tips include scissor cutting and blade cutting. During the scissor cutting process, two nurses are usually required to work together: one nurse uses two tweezers to clamp the two ends of the gutta-percha tip and align it with a ruler, while the other nurse is responsible for using scissors to cut off the excess part. However, due to the different comparison angles between the gutta-percha tip and the ruler, there is a deviation in the length measurement, which may lead to low cutting accuracy. Summary of the invention

[0004] The utility model aims to solve one of the technical problems in the related art to a certain extent. To this end, the utility model proposes a gutta-percha tip cutting device, through which the dentist can cut the gutta-percha tip more accurately, ensure accurate truncation of the gutta-percha tip, and improve the operation efficiency and treatment quality.
