Technical Field

[0001] This utility model relates to the field of facial plastic surgery technology, and in particular to an improved needle structure for facial micro-plastic surgery. Background Technology

[0002] Traditional syringes have a single function, requiring either blunt or sharp needles for injection, making it difficult for doctors to control the puncture depth during the injection process. Sharp needles can easily reach the desired puncture depth and location, but there is also a risk of puncturing nerves or blood vessels. In particular, if cosmetic agents are accidentally injected into a blood vessel, it can seriously endanger the patient's life and health.

[0003] Existing technology CN216495418U discloses an improved needle structure for facial micro-plastic surgery, including a cosmetic needle comprising a needle body and a needle tail; and a depth-fixing sleeve comprising an external depth-fixing tube and a positioning tail sleeve connected as an integral unit; the cosmetic needle is inserted into the depth-fixing sleeve, meaning the front end of the cosmetic needle body protrudes outside the front port of the external depth-fixing tube of the depth-fixing sleeve, while the needle tail of the cosmetic needle and the positioning tail sleeve of the depth-fixing sleeve are mutually positioned and engaged. The front port of the depth-fixing sleeve of this invention can rest against the patient's skin to prevent excessive puncture, meeting the needs of the modern medical aesthetics industry for puncture instruments.

[0004] However, the depth setting sleeve on existing cosmetic needles is usually fixed to the needle body. When performing cosmetic injections, the required puncture depth varies in areas such as the forehead, cheeks, around the eyes, and nasolabial folds due to their unique anatomical structures. This makes it impossible for existing cosmetic needles to adjust the position of the depth setting sleeve according to actual needs, making it difficult for medical personnel to understand the puncture depth of the needle body, which can easily lead to excessive puncture. Utility Model Content

[0005] The purpose of this invention is to provide an improved needle structure for facial micro-plastic surgery. It aims to solve the problem that the depth-fixing sleeve on existing cosmetic needles is usually fixed to the needle body. However, during injection cosmetic procedures, the required puncture depth varies in areas such as the forehead, cheeks, around the eyes, and nasolabial folds due to their unique anatomical structures. This makes it impossible for existing cosmetic needles to adjust the position of the depth-fixing sleeve according to actual needs, which makes it difficult for medical personnel to understand the puncture depth of the needle body and easily leads to excessive puncture.

[0006] To achieve the above objectives, this utility model provides an improved needle structure for facial micro-plastic surgery, comprising a syringe and a needle body, wherein the needle body is disposed on the syringe and located on one side of the syringe.
