ABSTRACT:
A microsurgery tool for use in anastomosis of small vessels has a thin arcuate shaft or tube with a tubular distal end having its tubing cut away to define a trough for receiving the pointed end of a suture needle. The microsurgery tool is inserted between confronting ends of vessels into a first vessel for receiving a suture needle point passing through the outer wall of the first vessel. Thereafter the tool is withdrawn from the space between the vessels and the convex outer surface of the trough engages the outer surface of the second vessel where it supports the wall of the second vessel while the point of the same suture needle is passed through the inner wall of the second vessel.
