[0002] In the field of orthodontics, push springs are a common auxiliary device used to adjust the position and occlusion of teeth. During clinical operation, push springs are clamped with tweezers. Push spring devices are mostly packed in bags. During operation, you need to open the package, clamp out the entire push spring, use a ruler to measure the length required for the actual operation, cut off the required push spring length, disinfect the remaining push spring, and put it back into the packaging bag for next use. The above operations are cumbersome and take up more time. In addition, repeated disinfection will have an adverse effect on the performance of the push spring material.
