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° 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.
A surgical clip formed from a suture material, to make an end-to-end suture on a mandrel in two axially aligned sections of a hollow organ, the latter having an outer diameter between 4 and 10 millimeters and a corresponding very small wall thickness, comprising a plurality of staples formed from pairs of sections of a strip, that are bent about a bending line, relative to a laterial axis of said strip, each staple comprising a. two arms constituted by said strip sections, extending from said bending line of the strip to respective free ends of the same staple, having different lengths, and respective planes substantially at an angle of 90° with respect to each other; b. substantially C-shaped cylindrical cross bars for said arms on the respective free ends; cylindrical surfaces of said cross bars having straight-line generatrices that are parallel to longitudinal axes of the respective arms; the difference in length between the longer one of said arms and the shorter other arm allowing at least one of the hollow organ sections to be grasped between said cylindrical surfaces of said cross bars when the latter are folded in use into a substantially overlapping position; said generatrices continually intersecting directing curves of the respective cylindrical surfaces; said directing curves being part of a circle substantially equal to the outer diameter of the at least one hollow organ section being grasped; and c. said shorter arm having an expanding portion for secure fixation in said mandrel; wherein 1. the center of said directing curve of the cross bar of said longer arm is on the side of the latter where said shorter arm is disposed; 2. the center of said directing curve of the cross bar of said shorter arm is on the opposite side of the latter, where said longer arm is disposed; 3. said cross bars provide for suturing by clamping therebetween the hollow organ sections when aligned on said mandrel and when said cross bars are folded into the overlapping position; and wherein 4. said longer arm is provided with at least one lug for securing said staple by puncturing the wall of at least one hollow organ section, said lug to be bent beyond the line of the suture formed between said cross bars, thereby increasing the strength of the suture in the hollow organ.

A surgical clip formed from a suture material, to make an end-to-end suture on a mandrel in two axially aligned sections of a hollow organ, the latter having an outer diameter between 4 and 10 millimeters and a corresponding very small wall thickness, comprising a plurality of staples formed from pairs of sections of a strip, that are bent about a bending line, relative to a laterial axis of said strip, each staple comprising a. two arms constituted by said strip sections, extending from said bending line of the strip to respective free ends of the same staple, having different lengths, and respective planes substantially at an angle of 90° with respect to each other; b. substantially C-shaped cylindrical cross bars for said arms on the respective free ends; cylindrical surfaces of said cross bars having straight-line generatrices that are parallel to longitudinal axes of the respective arms; the difference in length between the longer one of said arms and the shorter other arm allowing at least one of the hollow organ sections to be grasped between said cylindrical surfaces of said cross bars when the latter are folded in use into a substantially overlapping position; said generatrices continually intersecting directing curves of the respective cylindrical surfaces; said directing curves being part of a circle substantially equal to the outer diameter of the at least one hollow organ section being grasped; and c. said shorter arm having an expanding portion for secure fixation in said mandrel; wherein 1. the center of said directing curve of the cross bar of said longer arm is on the side of the latter where said shorter arm is disposed; 2. the center of said directing curve of the cross bar of said shorter arm is on the opposite side of the latter, where said longer arm is disposed; 3. said cross bars provide for suturing by clamping therebetween the hollow organ sections when aligned on said mandrel and when said cross bars are folded into the overlapping position; and wherein 4. said longer arm is provided with at least one lug for securing said staple by puncturing the wall of at least one hollow organ section, said lug to be bent beyond the line of the suture formed between said cross bars, thereby increasing the strength of the suture in the hollow organ.
