Abstract:
A spreading instrument includes instrument fingers which can be spread to partially define a cylindrical passage between the instrument fingers. A rounded groove on the interior surface of each instrument finger is tapered lengthwise, becoming shallower towards the distal end of the finger. When the fingers are spread, the opposing grooves partly define a cylindrical passage adapted to receive a tubular structure.
