A surgical device for joining severed body vessel walls comprises a pair of annular flanges each formed of a plastic material which is compatible with the human body. Pointed pins on one of the flanges are pierced through the vessel walls and inserted into apertures in the other flange to hold and locate the vessel walls. Threaded mounted pins on one of the flanges are inserted through openings in the other of the flanges and threaded nuts are threaded onto the threaded pins to clamp the vessel walls together with a clamping pressure. The clamping pressure may be adjusted by turning the threaded nuts. Clamping pressure may be relieved to prevent a necrotic condition by turning the nuts in the turn off direction.
