Patent attributes
A derma roller apparatus has a head, which has a cylindrical member and a plurality of needles situated around the cylindrical member. The width of the cylindrical member may be in a range of four to twelve inches. Furthermore, each of the plurality of needles may have a length of at least five tenths millimeters. In addition, the derma roller apparatus has a swivel, a connector, and a handle. The connector connects to a first endpoint of the head and a second endpoint of the head. Furthermore, the handle is operably attached to the connector via the swivel. The handle is configured to move along a yaw axis with respect to a collinear plane that is collinear with the head and the handle. Finally, the first endpoint and the second endpoint of the head are transverse to the collinear plane. As an alternative, the handle may be telescopic.
