Abstract:
1. A device for forming an end-to-end anastomisis on two hollow organs, which can be attached to a suturing machine with at least one motor driven needle bar with a thread-carrying needle, a shuttle cooperating with same, a needle plate, and a holding-down device for the material to be sutured accommodated by a push rod, the device comprising: a carrier comprising a hollow cylinder having a longitudinal axis that is configured to extend at an acute angle to the contact surface of the needle plate of the suturing machine and having a longitudinal slot for edge areas of the two hollow organs to be connected to one another; a bracket for connecting said carrier to the a housing shaft of the suturing machine in such a way that a longitudinal axis of said carrier runs transversely to the path of movement of the needle of the suturing machine, and a contact area for the two hollow organs is directed essentially parallel to the plane of the contact surface of the needle plate of the suturing machine; a sleeve, which is arranged coaxially to said carrier and can be rotated in relation to said carrier, said sleeve having a jacket surfact used as a contact surface for the end areas of the two hollow organs, and said sleeve having a sleeve longitudinal slot extending over at least a part of a length thereof; a clamping ring wherein said sleeve has faces and can be closed on one of said faces by means of said clamping ring, said clamping ring having a longitudinal slot corresponding to said sleeve longitudinal slot; and a sleeve drive, said sleeve being rotatable in relation to said carrier by means of said sleeve drive, and movement of said sleeve drive of said sleeve is diverted by the drive of the suturing machine in such a way that said sleeve makes an intermittent rotary movement in a phased manner depending on the movement of the needle bar or a push rod for the formation of a seam.
