Description

Technical Field

[0001] The utility model relates to the technical field of microneedle therapy, in particular to a microneedle head and an implantable microneedle roller device. Background Art

[0002] Microneedle therapy, also known as microneedle treatment, is a medical technique that uses fine needle-like instruments to mechanically or physically and minimally invasively stimulate skin soft tissues in order to obtain therapeutic or cosmetic effects. It can be accompanied by synchronous or stepwise administration of drugs or functional ingredients, and with the help of microneedles, its transdermal / absorption efficiency can be improved, thereby enhancing the therapeutic or cosmetic efficacy. Common microneedles on the market include roller microneedles, whose main body consists of a handle and a roller, and microneedles are arranged on the roller (usually with a length of 0.5 mm to 3 mm). As the roller rolls on the skin, the microneedles can form micropores on the skin or stimulate skin cells to initiate injury repair and regeneration effects, and at the same time introduce effective drugs or functional ingredients into the skin tissue.

[0003] When using a roller microneedle, the rolling of the wheel surface will cause the liquid on the skin surface to roll from one side to the other side, and it is impossible to keep the liquid on the skin surface all the time during treatment to maximize absorption. Moreover, when the microneedle head of the roller microneedle flips with the roller, the paths of its extraction and insertion are not the same. This difference in paths may not only cause the deflection of the microneedle head, but also increase the skin wound, thus affecting the treatment effect and safety. For this reason, we propose a microneedle head and an implantable microneedle roller device. Summary of the Utility Model
