Description
Technical field
The utility model relates to a kind of blunt needles for micro-shaping.
Background technique
Micro-shaping field, it will usually be related to injecting beauty, and inject the beauty early stage of development, most doctors are infused using sharp needle
It penetrates.Sharp needle injection is to carry out medical fluid push after directly being punctured on the skin to appropriate depth, can be injected into subcutaneous relatively deep tissue,
Sharp needle is injected because of easy to operate and syringe needle accurate positioning, is not easy to run the characteristics such as needle, and the highest injection side of global utilization rate is become
Formula, suitable for injecting treatment as masseter muscle hypertrophy, filling smoothing wrinkle and the treatment for filling the delicate areas such as nasolabial groove.But sharp needle note
Skin histology is easily squeezed or is torn by needle tubing during penetrating, and thorn sense is strong, can generate feeling of pain or secondary insult, skin injury compared with
Weight easily causes extravasated blood or green even more serious complication of becoming silted up after injection.
And in recent years, there is a kind of blunt needle (to be usually made by flexible flexible stainless steel material, needle point is in
It is arc-shaped) injection system.Blunt needle injection is first to carry out aperture on the skin using common sharp needle (hollow needle tubing, angle syringe needle)
Afterwards, it reuses blunt needle and penetrates into inside skin and injected.Blunt needle inject easily and fast, it is seamless painless, be mainly used for injection fill out
Sodium hyaluronate is filled, blunt needle can be made smoothly to advance in soft tissue, can be reduced postoperative swelling, and its flexible needle tubing can expire
The demand of sufficient face's camber line gets uniformly naturally face's lines with least inserting needle hole.But since blunt needle is flexible big, note
Injection polarization needle is poor during penetrating, and especially when human body deep tissues are injected, more difficult control, injection time are longer.
CN205268203U discloses a kind of blunt needle for micro-shaping, including needle stand and syringe needle tube, the syringe needle tube
Bottom end is connected with the needle stand, the top closure of the syringe needle tube, is provided with side opening by proximal portion on the syringe needle tube, described
