Technical Field

[0001] The utility model belongs to the technical field of dental implant drilling equipment, and more specifically, relates to a spiral dental drill. Background Art

[0002] Dental implant is very common in modern life. During the dental implant process, drilling is often required in the oral cavity. Drilling is usually processed with a drill bit. The drill bit generally includes a drill rod and cutting edges provided on the drill rod. When the drill rod rotates, drilling can be carried out through the cutting edges. However, the existing drill bits are prone to shaking during the drilling process, seriously affecting the drilling effect.

[0003] The drill bit can refer to the cutting head in (Chinese invention patent; publication number: CN117017536A; subject name: dental implant positioning assembly and its positioning method; publication date: November 10, 2023). Summary of the Utility Model

[0031] Please refer to Figures 1 to 3 , and now the spiral drill provided by the present utility model will be described. The spiral drill includes: a drill rod 1, a guiding cutting edge 2, and a side cutting edge 3; the guiding cutting edge 2 is disposed at one end of the drill rod 1 and is used to machine a guiding hole in the axial direction of the drill rod 1; the side cutting edge 3 is disposed on the side surface of the drill rod 1; the side cutting edge 3 is spirally wound around the drill rod 1.

[0032] Thus, please refer to Figure 1, Assume that the drill pipe 1 is vertically arranged, and the guiding blade 2 is located at the bottom end of the drill pipe 1; when the drill pipe 1 is driven to rotate by an external tool (external tool: for example, an external motor drives the drill pipe 1 to rotate) and the drill pipe 1 moves downward in the axial direction, the guiding blade 2 can be inserted into the original guiding hole on the external object (in one embodiment, the original guiding hole can be machined by other drill bits) to guide the axial movement of the drill pipe 1, greatly improving the stability of the drill pipe 1 and reducing the sway of the drill pipe 1; the guiding blade 2 can also machine a new guiding hole on the external object or further cut the original guiding hole, and then the guiding blade 2 is further matched with the new guiding hole or the original guiding hole; a side blade 3 is arranged on the side surface of the drill pipe 1, and when the drill pipe 1 rotates, the side blade 3 can cut the external object on the radially outer side of the drill pipe 1. The side blade 3 is spirally wound around the drill pipe 1, facilitating the discharge of debris along the spiral side blade 3. In addition, the timely discharge of debris can reduce the sway caused by the debris hitting the drill pipe 1.

[0033] Regarding the "side surface" of the drill pipe 1: We assume that the drill pipe 1 is cylindrical, and the side surface refers to the arc-shaped curved surface of the cylinder.

[0042] In one embodiment, the colored mark 4 is a coating layer with a color and coated on the drill rod 1.

[0043] In one embodiment, the color of the colored mark 4 is different from the color of the drill rod 1.

[0044] Further, please refer to Figures 1 to 3 , as a specific implementation of the spiral dental drill provided by the present utility model, the number of colored marks 4 is multiple; the multiple colored marks 4 are arranged in sequence along the drill rod 1. In this way, the user can more conveniently judge different depths of penetration of the drill rod 1 through the multiple colored marks 4.

[0045] Further, please refer to Figures 1 to 3 , as a specific implementation of the spiral dental drill provided by the present utility model, in the extending direction of the drill rod 1, any two adjacent colored marks 4 are respectively arranged at intervals. In this way, it is more convenient to judge different depths of penetration of the drill rod 1 through the colored marks 4 arranged at intervals.

[0046] Further, please refer to Figures 1 to 3 , as a specific implementation of the spiral dental drill provided by the present utility model, the drill rod 1 has a second groove 11 for dyeing; the second groove 11, the side cutting edge 3 and the guiding cutting edge 2 are arranged in sequence along the drill rod 1. In this way, the user can dye in the second groove 11 for quick identification of the types of drill rods 1 (for example, three colors represent three types of drill bits).

[0047] In one embodiment, the way of dyeing in the second groove 11 can be: coating a color layer with a predetermined color on the inner wall of the second groove 11.

[0048] In one embodiment, the second groove 11 is an annular groove. In one embodiment, the second groove 11 surrounds the drill pipe 1.
