PURPOSE: A microneedle roller is provided, which can be tightly connected to the skin surface while the roller revolves automatically according to the flexuosity of the body part. CONSTITUTION: A microneedle roller includes: a handle(10) where a user or a surgical operator can catch with his/her hands; a connector(20) which is combined to the end part of the handle; and a roller assembly(30) which is combined to the end part of the connector. The connector is installed between the handle and the roller assembly and then disassembles the roller assembly from the handle. The connector restrains the rotation of the roller assembly combined to the connector or cancels the restrained state. A support rod is integrally formed at the upper part of the handle. A guide tube is integrally formed to accept and support the support rod inside the connector. |
