Not all FUE punches for hair restoration are created equally.  Other than the punches Cole Instruments created, FUE punches have a thicker wall and are not as sharp.  Cole Instruments created the thinnest wall and sharpest punches on the market.  This is very important to the success of FUE hair transplant surgery.   

Removal of hair follicles in FUE depends on two forces.  One is the axial force or the inward pressure on the skin.  The second is the tangential force created by rotation or oscillation.  Both forces will be less with a thin wall and a sharp punch.  Lower forces create less fluid movement of the follicles.  This helps to reduce follicle transection or amputation of the follicles, which often results in such damage to the follicle that follicular survival is impaired.   

Cole Instruments recently created a new surgical punch that is serrated.  These punches reduce the surface area in contact with the skin. This reduces the force required to incise around the follicles even more.  Cole Instruments calls these new punches, the Surrounded punch.   

The Cole Instruments Graft Chiller Plate reduces the temperature of the follicles so that any follicles traumatized by extraction have a higher probability of survival. Follicle trauma with the Cole Punches and other extraction tools is very low compared to other FUE punches and extraction tools, however.
