Abstract
The device comprises a first part able to be provided on the free side of one of two hollow biological tissues bearing against each other and a second part able to be provided on the free side of the other of the two hollow biological tissues bearing against each other, the first part comprising two rows of needles enabling the walls of the two hollow biological tissues to be pierced to bring a first suturing thread, and optionally a cut for incising both walls, the second part comprising means for providing a second suturing thread in the loops of the first suturing thread.
Claims18
A device for suturing two hollow biological tissues bearing against each other, characterised in that it comprises a first part able to be provided on the free side of one of the two hollow biological tissues and a second part able to be provided on the free side of the other of the two hollow biological tissues, the first part and the second part cooperating together and comprising means for positioning them with respect to each other by grasping walls of the two hollow biological tissues bearing against each other,
- the first part comprising:
- a first reserve for a first suturing element,
- needles aligned along two rows located on either side of an axis of the first part, the needles having their sharp ends directed to the second part, the sharp ends of the needles each having means for receiving a loop the first suturing element, each needle having a hole located so as to lie in the loop of the first suturing element received by the needle and substantially in the loop plane, the hole communicating with an exterior edge of the needle through a slot called outlet channel,
- means for actuating the needles to bring them from a low initial position to a high final position, to pierce the walls of the two biological tissues through the sharp ends of the needles, and then to bring the needles back to their initial position,
- the second part comprising:
- a second reserve for a second suturing element,
- driving means for driving a first part of the second suturing element into the holes of the needles in one of the two rows of needles and for driving a second part of the second suturing element into the holes of the needles of the other row of needles when the needles are in the high position.
