Abstract
A microsurgery tool for use in anastomosis of small vessels has a thin shaft with a pair of forwardly projecting tines defining a throat for receiving the pointed end of a suture needle. The microsurgery tool is inserted between confronting ends of vessels into engagement with the inner wall of one vessel for receiving a suture needle point passing through the outer wall of the vessel and thereafter is withdrawn from the space between the vessels to engage the outer surface of the other vessel where it receives the pointed end of the same suture needle passing through the inner wall of the other vessel.
