First Claim
Patent Images
1. A device for obtaining a skin graft, the device comprising:
- a hollow body, the body having a distal end configured for placement on skin, the body further adapted to be coupled to a vacuum source, such that a negative pressure can be generated within the device when the body is placed on a donor'"'"'s skin to raise at least one blister; and
a harvesting member integrated in said body for cutting said blister produced on said skin, the harvesting member comprising a bottom plate, a cutter plate and a top plate, each plate having at least one hole, said holes forming an aligned hole array such that a raised skin blister can be pulled through the holes in each of the plates by the negative pressure, the harvesting member further comprising an actuator for moving the cutter plate to disrupt the alignment of holes and cut the raised blister.
