Description

High-speed mobile phone with spraying and sucking functions and dental drill

Technical Field

The invention relates to the technical field of medical instruments, in particular to a high-speed mobile phone with a spraying and sucking function and a dental drill.

Background

Impacted teeth are teeth that cannot erupt at all or partially because of the obstruction of adjacent teeth, bones, or soft tissue, and cannot erupt later. For impacted teeth or tooth embryos buried in jawbone, the traditional tooth extraction needs to cut the jawbone in a large range to remove resistance, and the problems of puncture of maxillary sinus or nerve injury of lower alveolus, large postoperative reaction, low tooth extraction matching degree of children and the like exist, so that the minimally invasive tooth extraction is promoted. The minimally invasive tooth extraction is a method for keeping soft and hard tissues as much as possible by adopting a minimally invasive tooth extraction means and instruments so as to reduce the damage to a patient as much as possible, improve the comfort level in the treatment process and facilitate the postoperative restoration and reconstruction.

The minimally invasive tooth extraction instruments commonly used in clinic at present are mainly a turbine and an ultrasonic osteotome. The turbine is a traditional minimally invasive tooth extraction instrument which is mainly used as a cutting tool to cut teeth into a plurality of small blocks so as to relieve resistance and facilitate extraction. The ultrasonic osteotome is a relatively novel minimally invasive tooth extraction instrument at present, has smaller trauma compared with a turbine, but has lower cutting efficiency, and can not further reduce the adverse reaction rate after operation for a longer operation time. The fundamental limitation of the existing minimally invasive tooth extraction instruments is that the cutting edge parts of the instruments are small in diameter, about 1-2 mm, the third molar tooth germ cannot be smashed in a massive and integral manner, large tooth fragments still need to be cut into the jaw bone in a large range to remove resistance, and the jaw bone needs to be extracted by matching with other tooth extraction instruments. The small diameter and the long and thin structure make the utility model have the functions of horizontal cutting and vertical drilling in a small range, and the function of vertical crushing in a large range is limited. They do not have the function of sucking and discharging debris and need a saliva sucking pipe to be arranged aside. The clinical operation has a series of disadvantages of blocking the sight, requiring additional assistant operation, causing discomfort due to the retention of excessive waste liquid in the oral cavity of a patient, and the like.

Disclosure of Invention

The invention aims to provide a high-speed mobile phone with a spraying and sucking function and a dental drill, and solves the technical problems that in the prior art, the cutting edge part of a minimally invasive tooth extracting instrument has small diameter, so that the minimally invasive tooth extracting instrument only has the functions of horizontal cutting and vertical small-range drilling, and the function of vertical large-range crushing is limited.

The invention discloses a dental drill which comprises a blade part, wherein the blade part is cylindrical, one section of the blade part is connected with a handle part, the other end of the blade part is an end blade, and the side surface of the blade part is provided with a peripheral blade.
