Abstract
The utility model discloses a need not root canal file of clinical preflex, it includes the file body, stalk portion and spacing pad, the file body is including transition portion, working portion, file point portion. The thick other end of working portion one end circle is sharp-pointed, and the thick end of circle of working portion passes through transition portion to be connected in the stalk portion, and the sharp end of working portion is equipped with file point portion, spacing cover is located on the transition portion. File point portion is equipped with angle of advance, and it includes two parameters: a pre-bending angle A and a pre-bending length L. The pre-bending angle has different combination forms of a pre-bending angle A and a pre-bending length L. The pre-bending operation used in clinic is avoided by arranging the root canal file with the pre-bending angle, the clinic operation difficulty is reduced, and the treatment success rate is increased; reducing patient treatment latency; the possibility of scratching of medical staff is reduced, and the iatrogenic infection probability is reduced; reduce the rejection rate of the root canal file.
Description
Technical Field
The utility model relates to a tooth root canal treatment field specifically is a root canal file that need not clinical preflex.
Background
An endodontic file is a medical instrument used to thoroughly eliminate a source of infection in a root canal in endodontic treatment. Because the root canal in the tooth generally has complicated three-dimensional walking, such as random bending, bifurcation, confluence and the like, the file body of a straight root canal file needs to be pre-bent to adapt to the root canal form when the root canal file is clinically used for preparing the complicated root canal.
The on-site pre-curved root canal file during clinical operation has the following problems: 1. because of the difficult operation, the file angle and the bending position after the manual pre-bending are difficult to control, so that the root canal form can not be well inosculated, and the failure of the root canal treatment can be caused; 2. the operation difficulty is high, and the poor pre-bending easily causes the scrapping of the root canal file and wastes; 3. the file body is tiny, and the sharp file is easy to scratch medical staff in the pre-bending operation process, so that the iatrogenic infection risk is increased; 4. the preparation time is long, the treatment time is prolonged, and the pain of the patient is increased.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model provides a root canal file that need not clinical preflex, it includes the file body, stalk portion and spacing pad, the file body is including transition portion, working portion, file point portion, for the thick other end of working portion one end circle is sharp-pointed, the thick end of working portion pass through the transition portion connect in the stalk portion, transition portion is located to the spacing pad cover.
Further, the sharp end of working portion is equipped with file point portion, file point portion is equipped with bent angle in advance, and it includes two parameters: a pre-bending angle A and a pre-bending length L.
Further, the pre-bending angle a and the pre-bending length L are respectively set with different parameter combinations for forming pre-bending angles of different specifications.
Compared with the prior art, the beneficial effects of the utility model are that:
the pre-bending operation used in clinic is avoided by arranging the root canal file with the pre-bending angle, the clinic operation difficulty is reduced, and the treatment success rate is increased; the rejection rate of the root canal file is reduced; the possibility of scratching of medical staff is reduced, and the iatrogenic infection probability is reduced; reducing patient treatment latency.

Detailed Description
The utility model provides a need not root canal file of clinical preflex will combine below the utility model discloses the embodiment in the drawing, right the utility model discloses technical scheme in the embodiment is clear, completely describe, and obviously, the embodiment that describes is only the utility model discloses a partial embodiment, rather than whole embodiment. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention. See, e.g., FIG. 2: the utility model provides a root canal file that need not clinical preflex, its includes file body 1, stalk portion 2 and spacing pad 4, file body 1 includes transition portion 101, working portion 102, file tip portion 103, the thick other end of working portion 102 one end circle is sharp-pointed, and the thick end of working portion 102 circle passes through transition portion 101 to be connected in stalk portion 2, transition portion 101 is located to 4 covers of spacing pad.
The outer side of the working part 102 is provided with threads, so that the inner wall of the root canal can be cleaned conveniently.
The sharp end of the working portion 102 is provided with a filing tip 103 to better penetrate into the narrow part of the root canal near the apical end. File point portion 103 is equipped with in advance bent angle 3, and it includes two parameters: prebending angle A, prebending length L, prebending angle A with prebending length L sets up different parameters respectively for form the prebending angle 3 of different specifications, the parameter of prebending angle can be marked at the stalk portion, makes things convenient for the dentist to the discernment that has different prebending angle root canal files.
In practice, the root canal files with different specifications of the preflex angle 3 are made into a set for selection by a clinician. So that the clinical pre-bending operation is not needed when the device is used clinically. Because the existence of angle in advance, the root canal file can go deep into crooked root canal effectively, and the root canal file has certain elasticity, after stretching into the root canal, because there is the restraint of root canal, the root canal file has some positions and hugs closely the root canal wall, because the existence of angle in advance, the root canal file can laminate the root canal wall better. Along with the rotation of root canal file with carry and carry, realize the comprehensive cleanness to root canal inner wall.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
