Description

Dental car needle

Technical Field

The utility model relates to a medical apparatus field, concretely relates to car needle for dentistry.

Background

The needle is a consumable tool for stomatologists and is a fine steel needle, and the needle consists of a needle head and a needle handle, can be inserted into a slow mobile phone and a planting machine for use, and helps the stomatologists to open cavities and repair teeth. The needle is divided into a Wugang needle and a carborundum needle, wherein the tungsten steel needle is widely used abroad, the carborundum needle is mainly used by domestic dentists, and the carborundum particles are subjected to impurity removal, demagnetization, rounding and purification treatment and have excellent sharpness and wear resistance. The carborundum needle has the advantages that carborundum gradually falls off in the using process, the service life of the needle is up to the end when the carborundum falls by half, and the dental needle mainly has two ways of causing cross infection, namely, the needle contacts saliva and blood of a patient in the operating process in the oral cavity and scraps cause surface pollution; secondly, the medical needle has pathogenic microorganisms and the like which are retained in the body in the treatment process, the dental outpatient has large multifluid, the use rate and the turnover rate of the medical needle are high, and how to better avoid cross infection is one of the important contents of dental medical care workers. Meanwhile, when the existing needle is used, the tooth is often damaged to a certain extent due to large vibration swing amplitude, and when the needle is used, the resistance of the tooth is often reduced suddenly when the needle is punctured, so that the needle extends into the tooth, and the pulp cavity is seriously damaged.

Detailed Description

The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples.

The application provides a car needle for dentistry for debridement when the clinical operation of dentistry, get rid of granulation tissue, not only improved the efficiency of getting rid of granulation tissue, can also obtain better effect of cleaing away, thereby effectively shortened the operating time, the postoperative reaction is better.

As shown in fig. 1 and 2, the dental bur of the present application includes a body 1 and a debridement head 2 mounted on the body 1, the body 1 including a handle 11 and a motor 12. Wherein, body 1 mainly used installation debridement head 2 does not specifically limit to the material of body 1, uses the more light material that has corrosion resisting property to make better to alleviate holistic quality, conveniently grip and use. The motor 12 is fixedly arranged on a head 111 of the handle 11, one end of the handle 11 far away from the motor 12 forms a holding part 112 for holding by a doctor, and the holding part 112 is preferably configured to conform to the shape of a hand. The motor 12 is preferably a micro motor to reduce the overall volume of the needle for convenient use by the doctor. The motor shaft of motor 12 stretches out, debridement head 2 is fixed on the motor shaft of motor 12, debridement head 2 include the body of rod 21 with set up in needle structure 22 on the body of rod 21, needle structure 22 includes a plurality of Y type needles 221, and is a plurality of Y type needle 221 is followed the circumference and the length direction equipartition of the body of rod 21. Set up Y type needle 221 in the length direction of the body of rod 21, can guarantee to obtain sufficient debridement area, set up Y type needle 221 in the circumferential direction of the body of rod 21, can guarantee that no matter how kind uses can both obtain better result of use, needn't pay attention to the direction of gripping when using, it is more convenient, high-efficient to use.

Preferably, the needle-like structure 22 has a length of 7-8mm to ensure thorough and efficient removal of granulation tissue during debridement. The Y-shaped needle 221 is made of a nickel-titanium material, and the nickel-titanium alloy is a shape memory alloy, is a special alloy capable of automatically restoring the plastic deformation thereof to the original shape at a certain specific temperature, and has good plasticity. The expansion and contraction rate of the spring is more than 20%, the fatigue life of the spring reaches 7 times of 10, the damping characteristic of the spring is 10 times higher than that of a common spring, and the corrosion resistance of the spring is superior to that of the best medical stainless steel at present, so that the spring can meet the application requirements of various engineering and medicine, and is a very excellent functional material. In addition, the nickel-titanium alloy has the excellent characteristics of wear resistance, corrosion resistance, high damping, superelasticity and the like besides the unique shape memory function.
