  • Patent number: 7926401
    Abstract: A tissue harvesting method and device for obtaining micrograft tissue particles within the size range of 50-1500 microns, and more preferably 500-1000 microns, and most preferably 600 microns. The particles may be processed after a piece of donor tissue has been excised from the donor site, or processed into the desired size directly at the donor site, and thereafter excised. Cutters having blades or cutting edges spaced in the range of 50-1500 microns are utilized to obtain particles within the desired size range. An elastomer is positioned between the cutting edges to push the excised particles out of the blades for ease of use.

  • Patent number: 5257567
    Abstract: A sheet cutting apparatus is provided for cutting sheets from one or more media supply rolls. A rotary cutter bar cooperates with a stationary bar to sever the media as it is fed between the two bars. The rotary cutter bar is driven by a motor whose output is monitored by a speed control circuit. During a cut cycle, the motor speed may decrease with an increasing load caused, for example, by a thicker weight media being cut. Uncorrected, the motor speed would decrease, causing a deviation in the straightness of the cut. The speed control circuit senses the changes from the normal speed of the motor during the cutting cycle and generates a feedback signal to the motor to raise the speed to the operation level.
