摘要：
A tissue punch including a barrel defining a first open end, a second open end, and inner diameter, an outer diameter, and a lumen there through. A piston is at least partially disposed within the lumen and pressed against the inner diameter of the barrel, the piston being configured to create negative pressure within the barrel when the piston is retracted. A cutting element defines a proximal end and a distal end, the proximal end of the cutting element being disposed at the second open end of the barrel, the distal end of the cutting element defining a cutting edge, the cutting element is in fluid communication with the barrel. A pushing element is slideably disposed about the outer diameter of the barrel, the pushing element is movable from a biased first position away from the cutting edge to a second position proximate the cutting edge.
