Abstract
The invention discloses a novel vascular punch employing compressive normal force for tissue separation from a targeted vessel. This invention is particularly designed for making a large round hole without massive bleeding in vascular surgery. A clean, non-frayed hole-making guided by the normal force cutting principle is realized using a site-biting punch mechanism. The side-biting vascular punch comprises a U-shaped razor blade cutter, a backstop for receiving the cutter, and a linkage mechanism, forming an aligned line of contact for normal compression force generation and thereby severing tissue out of the targeted vessel.
