Punches designed for precise excision of vascular wall segments of pre-determined length during surgical procedures. These punches are typically handheld, manual instruments with two blades including concentric matching sharp rings at the distal end that work together as a jaw, operated by manipulating pivoted ring handles configured at an angle (e.g., 90 degrees) to the blades. The jaws are frequently calibrated (e.g., in millimeters); vascular punches may be used for removal of vein or artery segments, frequently during anastomosis procedures.
