The technical scheme is as follows: the utility model provides a buffering formula dental drill of high sharpness, includes drill bit, stalk portion and pole portion, the drill bit is connected to the one end of stalk portion, other end connecting rod portion, the drill bit upper end is equipped with the cutting part, the cutting part has eight terminal surface helical teeth to the highest point of cutting edge helical teeth should be unanimous with the rotation direction when dental drill uses.
The buffer type dental drill with high sharpness reduces the rear angle of the cutting edge, so that the cutting edge is thinned, eight teeth of the dental drill are designed into inclined teeth, and the sharpness of the dental drill is improved. After the helical teeth are added, the capacity of the corresponding chip flute is also increased, so that the chip containing effect is improved. After the chip containing effect is improved, accumulated chips can be taken out of the oral cavity after the cutter is moved out, so that the cleaning is convenient.
Furthermore, the high-sharpness buffer dental drill is characterized in that the handle part is in a hexagonal column shape and is fixedly connected with the drill bit.
Further, in the high-sharpness buffer dental drill, the rod portion is cylindrical, and the rod portion is machined through centerless grinding, and the roughness Ra0.4 of the rod portion is achieved.
Further, the high sharpness buffer dental drill, the drill bit, the handle and the rod are integrally formed.
Further, the high sharpness buffer dental drill is characterized in that the handle part and the rod part are connected through a fillet.
Furthermore, in the high-sharpness buffer dental drill, the tail end of the rod part is provided with the mounting part, the mounting part is also provided with the clamping groove, and the clamping groove is opposite to the step surface.
The beneficial effects of the utility model are as follows:
(1) The high-sharpness buffer type dental drill is reasonable in structural design, and eight helical teeth are arranged on the blade part, so that the thickness of the drill and the rear angle of the cutting edge are reduced, the contact area between the drill bit and the operation surface is reduced, and the sharpness of the dental drill is improved;
(2) According to the high-sharpness buffer type dental drill, the handle is designed into the hexagonal column shape, the connection area of the handle and the drill bit is increased, the hexagonal structure plays a role in fixing, and the drill bit part is ensured to be more stable when the dental drill rotates to work.
(3) After the helical teeth are added, the capacity of the corresponding chip flute is increased, so that the chip containing and removing effects of the dental drill are improved, and a doctor can clean accumulated chips conveniently.
Drawings
FIG. 1 is a schematic view of a high sharpness buffer dental bur according to the present utility model;
Fig. 2 is a schematic view of the structure of the drill shank of the high sharpness buffer dental drill according to the present utility model.
In the figure: drill 1, blade 11, end bevel 111, shank 2, shank 3, mounting portion 31, engagement groove 311, and step surface 312.
Detailed Description
The utility model will be further elucidated with reference to the figures 1-2 and the specific examples.
In the description of the present utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," "outer," and the like indicate or are based on the orientation or positional relationship shown in the drawings, merely to facilitate description of the present utility model and to simplify the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present utility model.
Examples
As shown in fig. 1-2, the high sharpness buffer dental drill according to the present utility model comprises a drill bit 1, a shank 2 and a shank 3, wherein one end of the shank 2 is connected with the drill bit 1, the other end is connected with the shank 3, the upper end of the drill bit 1 is provided with a blade 11, the blade 11 has eight end-face helical teeth 111, and the highest point of the cutting-face helical teeth should be consistent with the rotation direction of the dental drill when in use. The sharpness of the dental drill is related to the thickness and the contact area of the cutting edge, the thinner the thickness of the cutting edge is, the smaller the contact surface of the dental drill and the surgical site is, the better the sharpness of the dental drill corresponds to, and the less harm is caused to a patient, otherwise; in order to better improve the sharpness of the cutting edge, the rear angle of each tooth is properly reduced by the cutting edge, so that the cutting edge is thinned; the end surfaces of the eight teeth of the dental drill blade part 11 are designed to be inclined teeth, the inclined teeth are inclined at a certain angle properly, and the highest point of the inclined teeth 111 on the end surface of the cutting edge is consistent with the rotation direction of the dental drill in use, so that the contact area between the dental drill and an operation surface is reduced, and the injury of the operation part of a patient is reduced as much as possible.
