A forceps for isolation of a part of a blood vessel during anastomosis comprises hinged levers and an automatic lock to hold the levers in the closed position. There are rings at one end of each lever, by which the forceps is held. The other ends of the levers bear jaws arranged at an angle toward the levers. One jaw has a longitudinal groove open on the side facing the opposite jaw, while the other jaw is made in the form of a ridge whose width is the same as that of the groove so that the ridge enters the groove as the jaws are pulled together. Each jaw has a removable part that does not extend to the jaw ends. This invention can advantageously be used to divide a part of a vessel into two parts along its longitudinal axis during anastomosis with mechanical suturing or ligation.

The instrument comprises a supporting part and a staple-receiving part connected pivotally to each other, their working ends carrying opposing longitudinal jaws. The longitudinal jaw of said staple-receiving part accommodates staple magazines. Made in said staple magazines in opposition to the staple-clinching indentations of the longitudinal jaw of the supporting part are transverse slots adapted to accommodate the members for driving said staples and said staples, and longitudinal slots adapted to accommodate bars with wedge-shaped ends facing said staple-driving members, adapted for cooperation with said staple-driving members, to drive out and insert said staples. The longitudinal slot of said staple-receiving part movably accommodates a knife blade movable jointly with said bars. The instrument includes a latch-type lock for retaining the two parts in a position where they are brought together to define a suturing gap therebetween, and means for preventing substantial traumatism of the layer-by-layer sutured organs and for ensuring the rigidity of the suturing unit of the instrument in the course of a suturing operation.
