ABSTRACT:
Surgical clip formed from a suture material, for end-to-end suturing of hollow organs on a mandrel, such as blood vessels from 4 to 10 millimeters in diameter. The clip holds a plurality of staples, each being formed as a strip bent relative to the lateral axis thereof at an angle of approximately 90.degree. and has two arms, of which the longer one extends from the a bending line one free end while the shorter arm extends from the same line to the other free end; and respective C-shaped cylindrical cross bars on the free ends of the arms, the generators of the cylindrical cross bars being parallel to the longitudinal axes of the respective arms while the directing curves are part of a circumference with a diameter approximately equal to the outer diameter of a hollow organ to be sutured. The center of the directing curve for the longer arm is on the same side of the plane of that arm where the shorter arm is disposed, whereas the same center for the directing curve for the cylindrical shorter arm is disposed, relative to the plane thereof, on the side opposite to that where the longer arm is disposed. One arm is longer than the other by a value approximately equal to twice the wall thickness of the hollow organ being sutured. The longer arm is provided with at least one lug for securing the staples by puncturing the walls of the hollow organ. Then the lug is bent beyond the line of the suture formed between the cross bars, thereby adding to the strength of the sutured portion of the hollow organ. The shorter arm has an expanding portion for secure fixation of the staples in the mandrel.
