AI Technical Summary
Traditional injection needles have difficulty controlling the depth of needle penetration into the skin, resulting in uneven penetration depth and unsightly phenomena such as excessive local bulging.
A cosmetic injection needle was designed, comprising a positioning structure and a limiting component. The insertion depth of the injection needle is changed by moving the sliding sleeve and the protective sleeve through the nut, and the depth is judged by contacting the skin through the positioning ring. After the injection is completed, the protective sleeve is used to protect the needle to avoid exposure and puncture.
It achieves uniform control of the injection needle depth, avoiding excessive local protrusion and skin punctures for medical personnel, thus improving the cosmetic effect and safety.
