Abstract
A surgical punch prevents tissue debris associated with punching a hole in a patient's tissue, such as an aorta during an anastomosis procedure, from reentering the patient's bloodstream. The punch includes elements that move the debris away from the cutting site and then capture that debris inside the instrument. The punch also includes means for aligning the punch with the selected site and for atraumatically holding the tissue prior to cutting. Various means for moving the tissue debris and for trapping the tissue debris in the instrument are also disclosed.
