Drill bit for tooth root bone hole drilling

Abstract

The invention discloses a drill bit for tooth root bone hole drilling, and belongs to the field of biomedicine instruments. A rotary cutting drill is included, the rotary cutting drill comprises a root tip part, a body part, a neck part and a head part, the root tip part is provided with double arc-shaped cutting blades, the double arch line cutting blades are connected with the body part to forman overflowing groove, the neck part is cylindrical, the neck part is connected with the body part to extend to the head part, the head part is hexagonal, the head part is fixedly connected with the neck part, and the centers of the root tip part, body part, neck part and head part are provided with connected fluid inlets. The drill bit has the advantages that the problem of the feed of the drillbit is solved by the specially designed double arch line cutting blades, the drill bit cooperates with the fluid inlets formed in the rear sides of the double arch line cutting blades, cooling liquidenters a hole drilling part through the fluid inlets to perform cooling, the fluid inlets are not blocked by chips due to the existence of the front-side double arch line cutting blades, a better cooling effect can be achieved, and the treatment efficiency and effect of a dentist are greatly improved.

Description

technical field [0001] The invention relates to the technical field of biomedical instruments, in particular to a drill bit for drilling root bone. Background technique [0002] Dental implant technology has been widely used in oral treatment. Drill bits are usually used in artificial dental implant technology, and the drill bit needs to rotate at a high speed, and the temperature of the alveolar bone during the dental implant process should not exceed 42 degrees, otherwise the bone tissue will die, and the implant and the surrounding bone tissue will not be able to grow. Integral effect; the existing internal cooling drill bits have internal cooling holes pierced at the top of the drill bit. This kind of internal cooling hole is pierced at the top of the drill bit. When in use, it faces the bone being drilled and receives axial pressure. , the cooling hole is prone to be blocked, which affects the normal discharge of the coolant and reduces the cooling effect, and because ...

AI Technical Summary

Problems solved by technology

Drills are usually used in artificial dental implants, and the drills need to rotate at high speed, and during the process of dental implants, the temperature of the alveolar bone drilled should not exceed 42 degrees, otherwise the bone tissue will die, and the growth of the implant and the surrounding bone tissue will not be achieved. The effect of integration; the existing internal cooling drills have internal cooling holes at the top of the drill. This kind of internal cooling hole is pierced at the top of the drill. When in use, it faces the bone being drilled and receives axial pressure. , it is easy for the cooling hole to be blocked, which will affect the normal discharge of the coolant and reduce the cooling effect, and because the cooling hole is opened on the top of the drill bit, the cutting edge of the drill bit will be damaged, which will reduce the cutting effect of the drill bit and increase the cutting force. The cutting heat of the bone makes it difficult for the dentist to grasp the feeding force, resulting in slow drilling and even the death of the surrounding bone tissue, which affects the effect of the dental implant.
