Description

{TREATMENT INSTRUMENT FOR DENTAL}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a dental surgery apparatus, and more particularly, to a dental surgery apparatus improved in convenience of operation by being easily replaced by various tip units.

Tooth decay, or dental caries, is a milky white, translucent, hard material that protects tooth dentin that covers the surface of the head of a tooth. Tooth enamel is caused by acid in the mouth, It is said to be damaged.

After cavities are formed, dental handpieces are used to form vortices for removing a portion of the teeth. Then, amalgam, light-cured resins, self-polymerizing resins, glass ionomers, gold inlays, resin inlays, zirconia Or the like as a filler. At this time, the filling material filled in the cavity is smoothed and condensed, and then smoothly polished, whereby the cavity treatment is completed.

During the course of this cavity treatment, a plugger to fill the filler, a burnisher to smoothen the filler, a carver to shape the filler to the tooth shape, Such as a mirror, a nerve removal file, and the like, are used.

Meanwhile, various dental tips as described above are formed in various sizes and shapes and selectively used by a therapist. However, a common dental tip is provided with tips of different sizes on both ends of one treatment instrument in the form of a handle. Therefore, in order to perform the dental treatment of the therapist, a plurality of tips must be provided, and there is a disadvantage that the different tips must be replaced and replaced. Therefore, in recent years, there have been various studies on a dental treatment apparatus that can increase the therapeutic convenience of a therapist.

The first to third tip brackets 33, 43 and 53 have an outer diameter smaller than that of the bridge bracket 12 so that a part of the first to third tip brackets 33, 43 and 53 can be inserted into the hollow bridge bracket 12.

The coupling unit 60 selectively couples the bridge unit 10 and the tip unit 20 to each other. The coupling unit 60 includes an engagement groove 61 provided in either the bridge unit 10 or the tip unit 20 and a bridge unit 10 or a tip unit 20 And an engaging protrusion 64 provided on the other one of the engaging projections 64a and 64b. In this embodiment, the coupling groove 61 is provided in the bridge unit 10, and the coupling protrusion 64 is provided in the tip unit 20.

More specifically, the engaging groove 61 is provided in the bridge bracket 12 provided inside the bridge cover 11, and the engaging projection 64 is engaged with the tip bracket 33 (43) of the tip unit 20, (Not shown). At this time, the coupling grooves 61 are provided at both ends of the bridge bracket 12, and the coupling protrusions 64 are provided at the respective tip portions 30, 40, and 50.

The coupling groove 61 has a first groove 62 formed in the direction in which the tip unit 20 is inserted with respect to the bridge unit 10, that is, the longitudinal direction of the bridge unit 10, And a second groove 63 extending in a direction orthogonal to the first direction, that is, in the circumferential direction of the bridge unit 10, so as to guide the engaging projections 64 not to move in the inserting direction. The first and second grooves 62 and 63 of the coupling groove 61 are interconnected in an "a" shape.

The coupling protrusions 64 are provided on the first to third tip brackets 33, 43 and 53 of the first to third tips 30, 40 and 50 and more specifically, 33, 43, and 53, which are coupled to both ends of the first to third tip brackets 12, respectively. These engaging projections 64 engage the tip unit 20 with respect to the bridge unit 10 by sequentially passing through the first and second grooves 62 and 63 and conversely, Grooves 62 in order to guide the tip unit 20 to be separated from the bridge unit 10.

The coupling unit 60 includes an O-ring 65 provided between the bridge unit 10 and the tip unit 20 for sealing between the bridge unit 10 and the tip unit 20, . The O-rings 65 are provided in a pair to seal both ends of the bridge bracket 12 of the bridge unit 10 and the tip unit 20. More specifically, an O-ring 65 is interposed between the end of the bridge bracket 12 and the plurality of tip brackets 33, 43,

The first to third tip brackets 33, 43 and 53 have smaller outer diameters than the bridge bracket 12 so that the first to third tip brackets 33 43) 53 are inserted into the bridge bracket 12 along the coupling groove 61 to a predetermined depth. The first to third tip brackets 33, 43 and 53 are provided with first to third tip fixing projections 34, 44 and 54 protruding to correspond to the outer diameter of the bridge bracket 12, Respectively.

With this configuration, in a state where the engaging projections 64 provided on the first to third tip brackets 33, 43, 53 are inserted and seated along the engaging grooves 61, An O-ring 65 is closely attached to the first to third tip fixing jaws 34, 44, and 54 provided on the respective tip brackets 33, 43 and 53 to seal the bridge unit 10 .

The assembling operation of the dental treatment apparatus 1 according to the present invention having the above-described structure will be described with reference to Figs. 2 to 4. Fig.

2, the first and second tip portions 30 and 40 are inserted into the bridge unit 10 in the longitudinal direction. At this time, the engaging projections 64 provided on the first and second tip brackets 33 and 43 of the first and second tips 30 and 40 are engaged with the bridge bracket 12 of the bridge unit 10, Are inserted along the first grooves 62 of the engaging grooves 61 provided at both ends of the engaging groove 61. [

Thereafter, as shown in Fig. 3, the first and second tip portions 30 and 40 are rotated by a predetermined angle in the illustrated arrow direction, respectively, and the first and second tip brackets 33 and 43 The engaging projections 64 are moved along the second grooves 63 of the engaging grooves 61 provided at both ends of the bridge bracket 12. [ Accordingly, the first and second tip portions 30 and 40 are engaged with the bridge unit 10 and are fixed without being moved in the insertion direction. At this time, an O-ring 65 is sealed between the first and second tip portions 30 and 40 and the bridge unit 10, respectively.

On the other hand, when the therapist wishes to replace the tip with a tip other than the first and second tips 30, 40, any one of the first and second tips 30, 40 coupled to the bridge unit 10 From the bridge unit (10). More specifically, in order to replace the first tip portion 30 with the third tip portion 50 shown in FIG. 4, the therapist rotates the first tip portion 30 in the direction opposite to the arrow shown in FIG. 3 And moves the engaging protrusion 64 along the second groove 63. Thereafter, the therapist moves the engaging projection 64 along the first groove 62 by moving the first tip portion 30 in the direction opposite to the arrow shown in Fig. 2, that is, in the direction opposite to the inserting direction, Thereby releasing the binding force of the first tip portion 30 with respect to the unit 10.

4, the engaging protrusion 64 provided on the third tip portion 50 is engaged with the engaging groove 61 provided in the bridge unit 10 in a state in which the first tip portion 30 is removed from the bridge unit 10, The third tip portion 50 is coupled to the bridge unit 10 by sequentially passing through the first and second grooves 62, At this time, an O-ring 65 is interposed between the bridge unit 10 and the third tip portion 50 which are mutually coupled to seal each other.

As described above, the tips 30, 40, 50 of the first to third tips 50 having the first, second, third, and fourth tips 31, 41, The bridge unit 10 can be easily replaced by inserting it into the bridge unit 10 and rotating the bridge unit 10 by a predetermined angle.
