ABSTRACT:
A surgical apparatus for suturing vessels with metal staples comprising an anvil part having two hinged halves, forming, when joined together, a working head at the end, with a through hole for the passage of the vessel to be sutured, and a bell mouth for the vessel spreading, and a staple part. The staple part includes two hinged L-shaped plates encompassing the working head on the outside. Recesses are provided on the outer surface of the working head's bell mouth for clinching the ends of the staples, and secured on the ends of the plates of the staple part are magazines with slots for staples and staple tappets, the slots of the stapple magazines are opposite the grooves on the bell mouth. The bell mouth of the working head is shaped, in section, as a polygon elongated in the direction of its two opposite apices lying on the split line of the working head.
The proposed apparatus provides for the suturing of vessels end-to-end, end-to-side and at an angle less than 90.degree., ensuring the suturing of vessels, both of the same and of different diameters, along the entire perimeter in a single stroke.
