Abstract: A device for transplanting small diameter hair grafts using a hand-held cutting instrument having a body holding the tool, a rotary cylindrical tool and a drive assembly capable of driving the tool in rotation with respect to the body. The tool has a hollow end for cutting a graft. The cylindrical tool is a hollow needle with an axial through bore of the same diameter as the hollow cutting end to which it forms an extension. The device extracts the graft by sucking it up through the axial bore of the needle.

Abstract: The invention relates to a device for surgical cutting of strips of scalp into multiple calibrated hair grafts, of identical small size. The device has a blade holder designed to allow vertical positioning of multiple parallel and equidistant blades, so that the cutting edges of said blades are aligned in one and the same horizontal plane, these blades then projecting from a support surface, and a plate of flexible material is intended to be placed flush with the cutting edges of the blades and is associated with an applicator associated with retention or abutment and, if appropriate, guide means making it possible to apply or press this plate onto the cutting edges of the blades, parallel to said support surface, while ensuring that this plate does not move beyond a limit position set at a distance from the support surface which is greater than the thickness of the strips for which the surgical cutting device is intended.
