Abstract

The present invention relates to a disk needle roller (100) for forming micro-holes in a surface of skin by using micro-needles (220) to stimulate and assist regeneration of the skin. The disk needle roller (100) includes a handle (110) having one pair of supporting bars (120) extended therefrom, and a roller (200) including a plurality of circular spacers (232, 233) placed on a rotation shaft (130) having opposite ends supported on the supporting bars (120) of the handle (110), a plurality of circular disks (210) each between adjacent circular spacers (232, 233) so that the circular disks (210) are rotatable around the rotation shaft (130) independent from one another, a plurality of needles (220) projected from an outside circumference of each of the disks (210) in a radial direction, each with a tip formed sharply for forming micro-holes in skin of a human body.

Claims

1. A disk needle roller comprising:

a handle having one pair of supporting bars extended therefrom; and

a roller including;

a plurality of circular spacers placed on a rotation

shaft having opposite ends supported on the supporting bars of the handle,

a plurality of circular disks each between adjacent circular spacers so that the

circular disks are rotatable around the rotation shaft independent from one another,

a plurality of needles projected from an outside circumference of each of the disks in a radial direction, each with a tip formed sharply for forming microholes in skin of a human body.

2. The disk needle roller as claimed in claim 1, wherein, in a front view of the disk, the needle has a right angular triangle, with perpendicular surface on an extension line from a center of the disk, and a sloped surface from a tip of the perpendicular surface to the disk.

3. The disk needle roller as claimed in claim 2, wherein one pair of adjacent needles has perpendicular surfaces and sloped surfaces arranged to face each other, respectively.

4. The disk needle roller as claimed in claim 1, further comprising a head mounted turnable around a rotation shaft at an angle with respect to a length direction of the handle, and the roller is mounted rotatable around a supporting shaft arranged perpendicular to an extension line of the rotation shaft of the head.

5. The disk needle roller as claimed in claim 4, wherein one of the head and the handle has projections, and the other one of head and the handle has recesses in conformity with the projections so that the head is secured to the handle after the head is turned step by step at a desired angle.

6. The disk needle roller as claimed in claim 1, wherein one or more than one disks is mounted between adjacent spacers.
