Description

Technical Field

[0001] This utility model relates to the field of dental resin delivery technology, and in particular to a novel dental flow resin delivery head. Background Technology

[0002] In dental restorations, flowing resin is widely used to fill cavities and repair tooth defects. To precisely deliver the flowing resin to specific areas of the tooth, a specially designed delivery tip is required. Previously, flowing resin delivery tips struggled to deliver resin at certain tooth corners because the tip was a fixed metal material at approximately 135 degrees, often failing to reach the desired location and proving inconvenient to use. Therefore, we propose a novel dental flowing resin delivery tip. Utility Model Content

[0003] The main objective of this invention is to provide a novel dental flow resin delivery head that can effectively solve the problems in the prior art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A novel dental flow resin delivery head includes a needle insertion connector and a reinforcing ring. The end of the needle insertion connector is connected to a first plastic conduit, the other end of the first plastic conduit is fixedly connected to a universal corrugated tube, and the other end of the universal corrugated tube is fixedly connected to a second plastic conduit. A shaped copper wire is fixedly installed through eight equal divisions on the inner side of the universal corrugated tube wall, and the two ends of the shaped copper wire extend to the inner sides of the first plastic conduit and the second plastic conduit, respectively.

[0006] Preferably, there are two reinforcing rings, which are respectively disposed on the inner side of the wall of the first plastic conduit and the second plastic conduit.

[0007] Preferably, the same end of the eight shaped copper wires is fixedly connected to the same reinforcing ring, and the other end of the eight shaped copper wires is fixedly connected to another reinforcing ring.

[0008] Preferably, a sealing gasket is fixedly installed on the edge of the insertion port of the needle connector.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] In this invention, the novel dental flow resin delivery head replaces the conventional fixed metal angle delivery head with a flexible plastic and metal composite delivery head. This delivery head structure can be twisted and adjusted to various directions, thus bending to reach various corners of the teeth, making it more convenient to use. Attached Figure Description

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0016] Example 1:

[0017] like Figure 1-3 As shown, a novel dental flow resin delivery head includes a needle insertion connector 1 and a reinforcing ring 6. The end of the needle insertion connector 1 is connected to a first plastic conduit 2, and the other end of the first plastic conduit 2 is fixedly connected to a universal corrugated tube 4. The other end of the universal corrugated tube 4 is fixedly connected to a second plastic conduit 3. A shaped copper wire 5 is fixedly installed through eight equal parts on the inner side of the universal corrugated tube 4. The two ends of the shaped copper wire 5 extend to the inner sides of the first plastic conduit 2 and the second plastic conduit 3, respectively.

[0018] Two reinforcing rings 6 are provided, and are respectively set on the inner side of the tube wall of the first plastic conduit 2 and the second plastic conduit 3; the same end of the eight shaped copper wires 5 is fixedly connected to the same reinforcing ring 6, and the other end of the eight shaped copper wires 5 is fixedly connected to another reinforcing ring 6. The eight shaped copper wires 5 are designed to bend and shape when the angle of the second plastic conduit 3 is adjusted, so as to avoid springback; a sealing gasket is fixedly installed on the edge of the insertion port of the needle tube connector 1, and the sealing gasket plays a sealing role when connecting the needle tube.

[0019] It should be noted that this utility model is a novel dental flow resin delivery head. In use, the needle connector 1 is first inserted into the delivery needle. Then, the doctor can use a sterile gloved hand to pinch the second plastic catheter 3 and move it to a specified angle. At this time, the universal corrugated tube 4 will bend. In this way, when the resin in the needle is delivered, the resin will enter the universal corrugated tube 4 through the first plastic catheter 2, and then be led out to the specified position in the oral cavity through the second plastic catheter 3, thereby completing the resin filling.

[0020] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
