Description

Technical Field

[0001] This utility model relates to oral medical devices, specifically a dental segmented molding clip. Background Technology

[0002] In dental filling treatment of proximal caries, a molded piece needs to be placed between the prepared cavity of the treated tooth and the adjacent tooth to isolate the affected tooth and restore the proximal surface shape and contact relationship. Traditional pliers-type and ring-shaped molded pieces create a planar proximal surface, which easily creates gaps between teeth, leading to food impaction. Segmented molded pieces, on the other hand, have a pre-formed convex shape, resulting in a convex proximal surface that more closely resembles the actual tooth shape. Segmented molded pieces need to be fixed between the two teeth using segmented molded piece clamps and wedges. Existing segmented molded piece clamps are usually U-shaped or circular, as seen in utility model patents with publication numbers CN206560476U and CN206026456U. These require special pliers to open the piece before placing it on the tooth, and after releasing the pliers, the molded piece's own elastic arms reposition and clamp the tooth, fixing it between the two teeth. The disadvantage of this type of segmented molded piece clamp is that it requires the use of pliers, increasing the operational complexity and cost of the molding system. Another design involves adding a gripping handle to the clamping arm of a segmented molding sheet, as described in the utility model patent with publication number CN210354945U. By squeezing the handle, the clamping arm is opened, thus eliminating the need for clamps. The problem with this design is that the handle and the clamping head form an equal-arm or force-intensive lever, making it difficult to squeeze. Lengthening the gripping handle would also cause inconvenience for intraoral operations. Utility Model Content

[0003] The proposed technical problem is to eliminate the clamps in the molding sheet system, thereby reducing operational complexity and cost; at the same time, to solve the problems of difficulty in clamping and pinching the molded sheet without clamps, and its large size.

[0004] The technical solution of this utility model is as follows: A dental segmented molding clip includes a first clip, a second clip, a first clip arm, a second clip arm, a first pinch handle, a second pinch handle, and an arm arch; the clip is connected to one end of the clip arm, the other end of the clip arm is connected to one end of the pinch handle, the other end of the pinch handle is connected to the arm arch, and the first clip arm and the second clip arm intersect near the first clip and the second clip.

[0005] In the above scheme, the dental segmented molding clip is integrally molded from stainless steel, elastic plastic material, or elastic nickel-titanium alloy.

[0006] In the above scheme, the clamping arm is either straight or curved.

[0007] In the above scheme, the cross-sectional shape of the clamp is semi-circular, triangular, or circular.

[0008] In the above scheme, the gripping handle is triangular, semi-circular, or square.

[0009] In the above scheme, the arm arch is semi-circular or triangular.

[0010] The beneficial effects of this utility model are: the dental segmented molding clip of this utility model has a simple structure, is easy to produce, and has a low cost. It does not require the use of clamps and can be opened by pinching with fingers, which is relatively labor-saving and convenient for placement and removal. Attached Figure Description

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments. The described embodiments are merely some embodiments of the present invention, and not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are all within the scope of protection of the present invention.

[0015] Example: See Figure 1 , Figure 2 A segmented dental clip includes a first clamp 1, a second clamp 7, a first clamping arm 2, a second clamping arm 9, a first gripping handle 3, a second gripping handle 8, and an arm arch 4. The first clamp 1 is connected to one end of the second clamping arm 9. The second clamping arm 9 intersects with the first clamping arm 2 near the first clamp 1 and the second clamp 7. The other end of the second clamping arm 9 is connected to one end of the second gripping handle 8. The other end of the second gripping handle 8 is connected to one end of the arm arch 4. The other end of the arm arch 4 is connected to one end of the first gripping handle 3. The other end of the first gripping handle 3 is connected to one end of the first clamping arm 2. The first clamping arm 2 is connected to the second clamping arm 7. 7 are connected; during use, pinch the first gripping handle 3 and the second gripping handle 8 with your fingers to squeeze the first clamping arm 2 and the second clamping arm 9. Due to the intersecting structure of the first clamping arm and the second clamping arm, the first clamp 1 and the second clamp 7 are separated. After placing them on the adjacent surface of the tooth where the molding piece 5 and the wedge 6 are installed, release your fingers. Rely on the rebound force of the arm arch 4 to clamp the first clamp 1 and the second clamp 7 tightly on the tooth. After filling is completed, pinch the first gripping handle 3 and the second gripping handle 8 with your fingers. The first clamp 1 and the second clamp 7 are separated. Remove the molding piece clamp and the molding piece 5 and the wedge 6, and continue to complete the tooth shaping and polishing operation.

[0016] The molded clip is integrally molded from stainless steel, elastic plastic, or elastic nickel-titanium alloy.

[0017] The clamping arms 2 and 9 are either straight lines or arcs.

[0018] The cross-sectional shape of the clamps 1 and 7 is semi-circular, triangular, or circular.

[0019] The grip handles 3 and 8 are triangular, semi-circular, or square.

[0020] The arm arch 4 is semi-circular or triangular.

[0021] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the scope of the technical solution of this utility model.
