Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a resin repair pen. Background Art

[0002] The dental resin restoration brush is a tool specially used in the process of dental resin restoration. It is widely used in the clinical restoration treatment of dental teeth. Its main functions include: shaping. After the resin is filled into the tooth, the brush can be used to shape it so that the resin material better conforms to the shape of the tooth and the shape of the occlusal surface; polishing. After the restoration is completed, the brush can also be used to polish the resin surface to make it smooth, improve the beauty of the tooth and reduce the adhesion of plaque; cleaning. During the resin restoration process, the brush can be used to clean the tooth surface, remove residual resin or other debris, and ensure the cleanliness of the restoration area; detail processing. The brush can help dentists process the fine parts of the tooth surface, such as texture, edges and corners, to achieve a more natural restoration effect; uniform coating. Before resin restoration, the brush can be used to evenly apply adhesive or acid etching agent to ensure that the tooth surface is evenly treated, which helps the bonding of the resin.

[0003] Because the current brush heads have a single shape and angle and cannot meet the targeted treatment and restoration needs of different tooth positions, during clinical treatment, dentists need to select brush heads of different specifications and angles according to the patient's specific situation to complete the treatment. Then, they need to prepare a variety of restorative brushes with different brush head shapes to meet the treatment needs, which makes the treatment process cumbersome and increases the treatment cost and time cost. Utility Model Content

[0004] The purpose of the utility model is to solve the above technical problems and provide a resin repair pen, wherein a straight head and a curved head are respectively provided at both ends of the pen body, and a brush is provided on the straight head and the curved head.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] This embodiment provides a resin repair pen, such as Figures 1 to 9 As shown, the pen body 1 comprises a straight head 2 and an elbow 3 at each end, each of which is provided with a brush 8. Dentists can choose different ends of the brush 8 (the brush 8 at the straight head 2 or the brush 8 at the elbow 3) to treat different tooth locations based on the patient's specific condition. This dual-use brush improves treatment efficiency. The term "dual-use brush" refers to having two usable brush heads, not just two uses.

[0029] In one embodiment, if Figures 1 to 9As shown, the brush 8 on the straight head 2 is detachably connected to the straight head 2. The brush 8 on the elbow 3 is also detachably connected to the elbow 3. This detachable connection offers two advantages: First, as the brush 8 is repeatedly used, it loses its original shape due to repeated cleaning and use, significantly reducing the repair effect. With this detachable connection, the brush 8 can be replaced with a new one as needed. Second, various types of brushes 8 can be replaced as needed, such as brushes of different lengths and bristles of varying hardness, to meet different treatment purposes. Third, the brush 8 can be used as a single-use consumable and can be replaced by one person, avoiding cross-infection and brush head deformation caused by repeated use that could affect the repair effect.

[0030] In one embodiment, if Figures 1 to 9 As shown, the elbow 3 includes a first elbow section 4 and a second elbow section 5. One end of the first elbow section 4 is connected to the brush 8, and the other end of the first elbow section 4 is connected to one end of the second elbow section 5. The other end of the second elbow section 5 is connected to the end of the pen body 1. The first elbow section 4 and the second elbow section 5 bend in opposite directions, giving the elbow 3 a double-bend structure. While the double-bend structure not only meets the full functionality of a traditional elbow, it also places the end point of the brush 8 closer to the axis of the pen body 1 than a single-bend elbow, making it more user-friendly and improving the accuracy of elbow 3 operation. This is because the second elbow section 5 bends the brush 8 outward away from the axis of the pen body 1, but then the second elbow section 5 bends the brush 8 back toward the axis of the pen body 1. A single-bend elbow only bends the brush 8 outward away from the axis of the pen body 1. When the brush 8 deviates far from the axis of the pen body 1, it can cause deviations in visual and tactile judgment, resulting in operational errors.

[0031] In one embodiment, if Figures 1 to 9 As shown, the brush 8 comprises a brush head 9 and a socket 10. The brush head 9 is positioned within one end of the socket 10, and the other end of the socket 10 is adapted to connect with the straight head 2 or the elbow 3. Preferably, the brush head 9 and the socket 10 are coaxially arranged, with the socket 10 coaxially positioned with the connection point of the straight head 2 or the elbow 3. The brush 8 can be purchased directly from a commercially available, mature, and compatible resin aesthetic restoration brush.

[0032] In one embodiment, if Figures 1 to 9 As shown, the first elbow section 4 and the second elbow section 5 have a bend angle of 120°. This angle design makes the elbow 3 easier to target the posterior maxillofacial area, lingual area, and adjacent axial angle area. Of course, this bend angle is only one setting method, and different bend angles can be set according to different targeting locations.

[0033] In one embodiment, if Figures 1 to 9 As shown, the cross section of the pen body 1 is triangular, that is, the pen body 1 is roughly in the shape of a triangular prism, which is more suitable for pinching with fingers, and the pen body 1 can be rotated to adjust the angle during use.

[0034] Further, in one embodiment, if Figures 1 to 9 As shown, the three corners of the triangle are arc-shaped corners, so that the edges of the triangular prism-shaped pen body 1 are rounded, which improves the comfort of finger pinching.

[0035] In one embodiment, if Figures 1 to 9 As shown, the pen body 1 includes a first grip section 6 and a second grip section 7. One end of the first grip section 6 is provided with a straight head 2, the other end of the first grip section 6 is connected to one end of the second grip section 7, and the other end of the second grip section 7 is provided with an elbow 3. The first grip section 6 and the second grip section 7 are both streamlined with small ends and large middle, which is convenient for holding and pinching.

[0036] In one embodiment, if Figures 1 to 9 As shown, the pen body 1 is made of a high-temperature resistant polymer material, which allows the pen body 1 to be sterilized at high temperatures. The high-temperature resistant polymer material can be made of nylon (polyamide fiber), PEEK (polyetheretherketone), PC plastic (polycarbonate), TPE (thermoplastic elastomer, also known as artificial rubber or synthetic rubber), and other high-temperature sterilizable materials.

[0037] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
