摘要

A surgical stapling device comprises a shaft 10, a surgical staple 14 slidab le longitudinally within the shaft, and a staple-firing mechanism 16, 24 for driving the staple towards the forward end of the housing, bending the stapl e to bring the free ends of the legs towards one another to close the staple, and releasing the closed staple. The device also includes a blood locator tu be 18 slidable longitudinally within the shaft between an initial extended position wherein a forward end of the tube projects beyond the forward end o f the shaft to enter a puncture site in a liquid- carrying vessel in a human o r animal, thereby to locate the forward end of the shaft at the puncture site, and a retracted position wherein the tube is retracted into the housing in coordination with the closure of the staple. The tube 18 has a longitudinal slot 20 extending rearwardly from its forward end and the back of the staple is accommodated transversely in the slot.
