Technical Field
[0001] The utility model belongs to the technical field, and particularly relates to a needle. Background Art
[0002] Medical beauty negative pressure five-speed adjustable nine needles, water light injection mesodermal therapy is to inject nutrients directly into the deep layer of the skin through the needle. Currently, there are two common categories in the industry: fixed length needles and threaded adjustable length needles: fixed length needles are the mainstream in the market and industry. The fixed length needle is 1.5 mm, and the fixed length cannot be adjusted. The disadvantage of this needle is that it cannot adjust the depth of entry into the skin according to the thickness of the skin and the efficacy of the product, and it is not flexible enough to use. Another threaded adjustable length needle is to adjust the needle between 0-4 mm by rotating the thread. By rotating the cap on the top of the needle, the thread drives the piston inside the needle to expand and contract, thereby achieving the effect of adjusting the depth of the needle.
[0003] However, the disadvantage of the current technology is that the traditional needle structure often has the technical problem of liquid leakage during use, resulting in poor overall sealing and affecting the overall use effect. Utility Model Content
