Abstract
Paired vascular clamps simplify laparoscopic vascular reconstruction surgery by providing an instrument for bringing vessel ends together to a reasonable working distance under a controlled fashion. A first clamp, with a pivoted connecting arm, and a second clamp with a lock/release device for attaching the second clamp to the connecting arm, can be inserted through an trocar or other port into a surgical field and then positioned on with the first clam and the second clamp in side-by-side and substantially parallel relationship, so that said first clamp and said second clamp can hold and position one or more vessels or elongated tissues. A laparoscopic approximator-everter has extendable blades for gripping blood vessel edges or other tissue to be anamosted, and an extendable sheath that can be advanced to surround the blades. Notches in the end of the sheath automatically evert and approximate the blood vessel edges for laparoscopic clip application or suturing when the sheath is advanced to surround the blades.
