AI Technical Summary
Existing root canal files are processed by horizontally cutting one surface, which results in stress concentration points, easy breakage and poor cutting ability.
A root canal file for a circular cutting machine is designed, comprising an integrally formed non-threaded portion and a threaded portion. The threaded portion is provided with a circular cutting surface, which continuously spirally extends from the head of the threaded portion to the root. The circular cutting surface is a curved surface and extends to the non-threaded portion, which is cylindrical.
Improve the cutting ability of root canal files, reduce surgical difficulty, reduce the risk of breakage, and improve surgical efficiency.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to medical instrument technical field, concretely relates to a root canal file for ring cutting plane machine. BACKGROUND
[0002] At present, the root canal file for machine is all adopted horizontal cutting plane processing method, for example, the root canal file disclosed in CN115337120A, the horizontal cutting plane processing method has the problem of stress concentration point, is easy to break, and the root canal file is used as cutting tool, and the horizontal cutting plane cutting capacity is poor. SUMMARY
[0003] In view of the deficiency in the prior art, the utility model provides a root canal file for ring cutting plane machine, which can disperse stress concentration, improve the cutting capacity of the root canal file and reduce the risk of root canal file breakage.
[0004] The utility model is realized through the following technical schemes:
[0005] The utility model provides a root canal file for ring cutting plane machine, which comprises a root canal file main body, the root canal file main body comprises an integrally-formed non-threaded part and threaded part, a ring cutting plane is formed on the threaded part, and the ring cutting plane continuously spirally extends from the head of the threaded part to the root of the threaded part.
[0006] In a preferred embodiment of the utility model, the ring cutting plane is a curved surface.
[0007] In order to facilitate processing and operation, the non-threaded part is in a cylindrical structure, and the diameter of the non-threaded part is the same as that of the head of the threaded part.
[0008] In order to facilitate use, the ring cutting plane extends to the non-threaded part.
[0009] The root canal file for ring cutting plane machine has the advantages that the root canal file is processed in the form of a ring cutting plane, the cutting capacity of the root canal file is improved, the difficulty of surgery is reduced, and the efficiency of surgery is greatly improved; the unique ring cutting surface can effectively disperse stress concentration and reduce the risk of root canal file breakage.

[0012] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.
[0013] like Figure 1 、 Figure 2 The illustrated embodiment of a circular cutting machine-use root canal file comprises a root canal file body, the file body comprising an integrally formed non-threaded portion 1 and a threaded portion 2. The threaded portion 2 is provided with a circular cutting surface 3, which is a spirally wound structure. The circular cutting surface 3 continuously spirally extends from the head of the threaded portion 2 to the root of the threaded portion 2, and the circular cutting surface extends about 3 mm into the non-threaded portion 1. The circular cutting surface 3 is an inwardly concave curved surface, and its depth is about one-fifth of the diameter of the threaded portion 2. The non-threaded portion 1 is a cylindrical structure, and the diameter of the non-threaded portion 1 is the same as the diameter of the head of the threaded portion 2.
[0014] The annular section machine-used root canal file adopts an annular section processing form to improve the cutting ability of the root canal file, reduce the difficulty of surgery, and greatly improve the efficiency of surgery; the unique annular section can effectively disperse the stress concentration problem and reduce the risk of root canal file breakage.
[0015] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the concept of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
