Abstract

The surgical suturing machine comprises a housing (10) on whose head piece (14) a needle holder (16) holding a needle (30), a thread catcher (18), a rotatable cylindrical body (20), a fixed foot with a plate (70) and a stretcher (22) are releasably mounted. The projecting tissue edges to be sutured together are clamped between plates (70) and cylindrical body (20). When the surgical suturing machine advances, the shaped circumferential surface (78) of cylindrical body (20) rolls along the outside of one edge of the tissue. The circumferential surface (78) of the rotating cylindrical body 'grips' the outer surface of one tissue edge and guides the two tissue edges into a clamping zone which is located in the vicinity of the shortest distance between plate (70) and circumference (78) of the cylindrical body (20). The projecting tissue edges are pierced by needle (30) in the clamping zone and sutured together with the aid of thread catcher (18) and needle (30 ). Then they are pressed flat by stretcher (22) so that the edges of the tissue are opposite and abutting one another. In a second embodiment a suction air holding device (240) which acts during each suturing process is provided in the suturing area of needle (203) for the tissue edges, said device (240) being raisable and lowerable by drive mechanism (236-239) in the vertical plane.
