Supplementary vascular clamp for the tool kit of an open approach stapler

The present invention relates to medicine, in particular, to clamps used in vascular surgery for occlusion of blood vessels during a surgical operation, such as vascular clamps used in aortic aneurysm repair. The claimed supplementary vascular clamp comprises a pair of pivoting arms, each of them having a proximal end and a distal handle end. Each pivoting arm contains clamping jaws rigidly attached to a respective proximal end of this arm and shaped as a concave semi-cylindrical or semi-oval cavity. The clamping jaws are movable between the open position and closed position and define a through cylindrical or oval cavity in their closed position. The clamping jaws of the vascular clamp are also provided with a tightening means to provide intra-aortal bending of the ends of staples of an open approach stapler. The tightening means is shaped as plates or a strip of resilient material. The strip may be provided with a tensioning device. The vascular clamp may be also provided with a compensating means for correcting non-uniformity in the thickness of aorta walls. The vascular clamp may be further provided with a compensating means for correction of irregularity in wall thickness of the aorta, a first and a second sealing means for providing secure enclosure of aorta walls, as well as a means for providing regular ejection of staples.
