Ultrasonic wave syringe needle for dental department and medical treatment and manufacture method thereof

Abstract

The invention provides an ultrasonic wave syringe needle for a dental department and medical treatment and a manufacture method thereof, wherein the durability and reliability of the ultrasonic wave syringe needle can be improved, and the ultrasonic wave syringe needle is easy to manufacture. The manufacture method of the ultrasonic wave syringe needle for the dental department and the medical treatment comprises the following steps: ejecting shaped mixture comprising powder to manufacture a middle shaping body, wherein the middle shaping body comprises a syringe body and a plurality of syringe bulges, and the syringe bulges are integrated on the surface of the syringe body and form a bulge; and sintering the middle shaping body.

Description

technical field [0001] The present invention relates to a dental and medical ultrasonic needle and its manufacturing method, more specifically, relates to a dental and medical ultrasonic needle which can improve durability and reliability and is easy to manufacture and its manufacturing method. Background technique [0002] Ultrasonic needles used in dentistry are used to vibrate needles using ultrasonic vibration energy to remove tartar and other attached foreign matter deposited on teeth or to perform nerve treatment (root canal surgery), in addition to being widely used in dental implant surgery , periodontal surgery, oral surgery and maxillofacial surgery and other dental treatments. In addition, ultrasonic needles for medical use are used for plastic surgery on bones, such as osteotomy, drilling, saucerization of cortical bone, etc. And for cosmetic surgery, that is, when performing all operations such as vibration (oscillation), reciprocation (reciprocation) of mechan...

AI Technical Summary

Problems solved by technology

[0004] However, the existing ultrasonic needles used in dentistry are made by conventional machining such as cutting and grinding, so there are problems of difficulty in precision machining and a high incidence of defective products

In addition, in the past, the surface of ultrasonic needles used in dentistry required additional processing to form a coating, so there was a problem of increased production man-hours and costs.

[0005] As mentioned above, conventional ultrasonic needles used in dentistry are manufactured by machining, so there are following problems, that is, it is difficult to increase the machining precision beyond a certain level, there is a limitation that only materials that can be easily machined can be used, and the production unit price is high and expensive. Slow processing speed, not conducive to mass production

[0006] In addition, the existing ultrasonic needles used in dentistry have the problem of partial shedding of the coating on the surface of the needle due to repeated contact and friction with the teeth, so there will be problems of low treatment efficiency and low medical safety

In particular, the coating particles (diamond particles) of ultrasonic needles used in conventional dentistry have the problem that they are easily detached from the coating, which leads to a decrease in durability and service life, and hinders the accuracy and convenience of treatment.
