Abstract

The invention discloses a novel gutta percha point trimmer. A dentist selects a gutta percha point to-be-trimmed and determines the size of a section to-be-trimmed, then, the gutta percha point is rotationally inserted into a positioning hole with the corresponding specification and size, then a sliding block is pushed by a hand, the sliding block slides on a base; further, blades cut off the redundant part of the gutta percha point, the gutta-percha point with the required size is trimmed, the accurate size of the cutting section of the gutta-percha point can be guaranteed through the positioning holes of different specifications, the blades are symmetrically arranged in a sliding groove, on one hand, bidirectional free cutting can be conducted along the base, on the other hand, the bladepoints of the blades are not exposed, and safety and reliability are higher; according to the novel gutta-percha point trimmer, the gutta percha points are cut on a guide rail, the unnecessary contact area of the blade during cutting can be reduced, the blades can be attached to the guide rail more tightly, and therefore the use effect of the novel gutta percha point trimmer is improved, and theuser experience feeling is better.

Description

technical field [0001] The invention relates to the field of oral medical instruments, in particular to a novel gutta-percha tip trimmer.
