Description

Benting Structure of Dental Instruments {BANDING STRUCTURE OF DENTAL INSTRUMENTS}

The present invention relates to a structure of a bent portion of a dental instrument, and more particularly, when diagnosing or treating a tooth in the oral cavity, a three-dimensional bending effectively bent so that the extension part does not interfere with the lips even when the instrument is used in any direction. It's about structure.

In general, the dental instruments are divided into diagnostic instruments, periodontal instruments, surgical instruments, etc. according to the purpose of use, which can be seen through FIG. 1.

The first picture of FIG. 1 is a diagnostic explorer, which is used for detecting caries and calculus, the state and branching of pockets, and the examination of restorations. , Gingival bleeding, etc. The third picture is to be used as a hammer (Mallets) to impact the teeth.

The common features of such diagnostic instruments, periodontal instruments, and surgical instruments include an end portion (or action portion) in contact with a tooth, a handle portion (or bag) that is easy to hold by hand, and an extension portion therebetween. The extension usually has a bend to ensure that the tip does not interfere with the patient's lip when the tip contacts the tooth.

However, the bends of these instruments have one or two bends, but based on the axis of the handle, they are planar bends but not three-dimensional bends.

For example, as shown in FIG. 2, the instruments T may be easily used to contact the teeth D inside the lips M, but each of the instruments T may be used for diagnosis or treatment. Most of the instruments have their own orientations, that is, the ends (or acting portions) of the respective instruments have a directionality that acts according to the purpose of scraping, cutting or digging.

In order to effectively use the directional end portion along the various parts of the tooth at that time, it may be rotated or rotated at various angles. When the instrument is rotated from the state of FIG. There are many instances where M) is disadvantageous due to greater interference.

Therefore, the present invention is to devise to solve the above-mentioned conventional problems, the main object of the invention is to turn the instrument in any direction by placing a bent at a new angle in the extension between the handle portion and the end of the dental instrument Even though it is intended to prevent interference with the lip of the patient, it is more difficult to go out and reduce the difficulty of opening the mouth to the patient, to facilitate access to places that are difficult to access the dental instrument, and it is convenient for the operator. It is to provide.

A characteristic configuration of the present invention for achieving the above object is a dental instrument having a handle portion, an end action portion, and an extension therebetween, wherein the extension portion is in an arbitrary direction and at an arbitrary angle at the primary bend point. A first bent portion bent at an angle of α ° with respect to the axial direction of the handle; Bend at any angle and in any direction at the second bending point of the point that guarantees any length from the first bending point, in the axial direction of the handle without being parallel to the extension and the primary bent portion A secondary bent portion that is bent at an angle of α ° in the longitudinal direction away from it; At the third bending point of the point that guarantees an arbitrary second length from the second bending point bend at any angle and in any direction, unless the parallel to the extension, the first bent portion, the secondary bent portion And a third bent portion bent at an angle of α ° in the longitudinal direction closer to the axial direction of the handle, wherein α is about 90 ° to 120 °.

Hereinafter, the configuration and operation of the present invention will be described in detail with reference to the accompanying drawings.

Figure 3 is an exemplary view of a dental instrument bending the extension in accordance with an embodiment of the present invention, Figure 4 is a front view and a plan view showing the bent state in more detail.

The present invention can be implemented as long as the handle portion 10, the extension portion 30, and the end action portion 20 of the extension end is integrally configured among the dental instruments.

That is, in all the dental instruments having the handle portion 10, the end action portion 20, and the extension portion 30 therebetween, the extension portion is the primary bending portion 31 and the secondary bending. It is an important structure that it forms by bending the part 32 and the tertiary bent part 33. FIG.

The primary bent part 31 bends the extension part 30 in any direction and at an angle at the primary bend point A, and is bent at an angle of α ° with respect to the axial direction of the handle. The secondary bent part 32 is bent at any angle and in an arbitrary angle at the second bent point B at a point that guarantees an arbitrary length from the primary bent point A, but the extension part 30 and the first bent part 31 is bent at an angle of α ° in the longitudinal direction away from the axial direction of the handle, and the third bent part 33 is the second bent point ( B is bent in any direction and at an angle at the third bending point C at a point guaranteeing an arbitrary length, and the extension part 30, the primary bent part 31, and the secondary bend. It is bent at an angle of α ° in the longitudinal direction closer to the axial direction of the handle without being parallel to the part 32.

Herein, the above α ° is about 90 ° to 120 °, preferably 110 °. And this is as shown in FIG.

The present invention may be implemented as in FIG. 5 in some cases.

That is, in the case of FIG. 5, the primary, secondary, and tertiary bent portions are sequentially formed, and in forming the tertiary bent portion 33, the tertiary bent point C is formed on the secondary bent portion 32. When it is bent from, it is characterized in that the bent axial direction thereof is concentric with the axial direction of the extension portion 30 described above.

In the dental instrument of the present invention configured as described above, since the extension part 30 is bent as a bent portion extending from 1st to 3rd, as shown in FIGS. 6A and 6C, no matter what direction the tooth approaches. Likewise, the procedure can be performed without causing much interference to the side of the lips.

That is, as shown in Figure 6a, the end action portion 20 is in a state approached to face the upper surface of the tooth, in this case the second bending point (B) of the extension portion 30 is the outermost, this Because the lips touch the part, the patient can be treated without having to open her mouth as before.

In addition, as shown in Figure 6b, the end action portion 20 is approached toward the lower side of the outer side of the tooth, in this case, because the primary bending point (A) is the outermost to the lips The tip touches. Therefore, even in this case, the patient can be treated without opening the mouth very much.

In addition, as shown in Figure 6c, the end action portion 20 is in a state approaching toward the front side of the tooth, in which case the second bending point (B) or the third bending point (C) toward the outermost This also means that the mouth is less open than conventional instruments.

Meanwhile, as shown in FIG. 5, the axial direction of the tertiary bent portion 33 that is bent at the tertiary bent point C on the secondary bent portion 32 is concentric with the axial direction of the extension portion 30 described above. If the force is to be transmitted from the handle portion 10 to the end action portion 20 through the extension portion 30, for example, the force may be effective when the price (Mallets) and the like.

For reference, in the case of various handpieces (electrical tools used with tooth cutting tools and grinding tools) installed in the dental chair unit, the extension part of the present invention may be used in addition to the diagnostic device and the surgical device shown in the drawings. Applicable to the extension of.

The dental instrument of the present invention as described in detail above bends the extension portion leading to the handle rotor end action two or more times, and its direction is three-dimensionally deflected so that any interference with teeth and soft tissues in any direction greatly affects the side of the lips. It is possible to access without causing it.

Therefore, the patient's difficulty in opening the mouth greatly is reduced, and it is possible to more easily access the difficult part for access to the incision in the oral lingual area, and improve the condition for the operator to be convenient for various procedures.
