Abstract: A fluidthight surgical staple for a surgical stapling device comprises a deformable back that comprises two parts that are hinged with respect to each other and at least four rows of anchoring pins. The back remains substantially flat when the staple is in place, so that it does not protrude from the wall of the organ; when the back is in the open position, the axes of the pins of the two central rows tend to align parallel to each other and the tips of the pins are separated by a gap larger than in the closed position. At least a second row of converging second anchoring pins is placed towards the outer side of each hinged part of the back. The staple is provided with gripping points for keeping the staple in open or closed position.

Abstract: A surgical clamping device for hollow anatomical structures such as, essentially, blood vessels, but also tracheas, intestines, etc. This device comprises three initially independent parts, namely two jaws, each jaw being formed of an elongate member having distal and proximal ends, and a mandrel that can be slipped over the proximal ends of the two jaws and that is able to bring the axes of the two jaws closer together, thus pinching an anatomical structure. The mandrel comprises a distal, pinching part and a proximal, handling part, these two parts being joined together by a locking part, the jaws being bendable at the level of the locking part when the clamp is activated, the distal, pinching part of the mandrel remaining in place by friction on the jaws when it is unlocked from the proximal, handling part. This surgical clamping device applies more particularly to the clamping of the aorta.

Abstract: A Surgical retractor, designed in particular for minimally invasive operations, consisting essentially of an elastic plate rolled up about an axis so as to form the side wall of a substantially truncated cone shape, the narrowest cross section of the truncated cone constituting the distal part of this retractor, when the retractor is in place, and delimiting an operating field, the widest cross section of the truncated cone forming the proximal part, through which instruments can be introduced, said plate being able to be rolled up into a substantially cylindrical shape with a diameter smaller than or equal to the narrowest cross section of its truncated cone shape.

Abstract: A surgical clamping device for hollow anatomical structures such as, essentially, blood vessels, but also for tracheas, intestines, etc. This device comprises a flexible guide and two jaws, each jaw being formed of an elongate member pierced with a longitudinal canal and having a distal end and a proximal end. These jaws can be slipped over the guide with their proximal end facing toward each of the ends of the guide. A mandrel is slipped over the two ends of the guide and brings the axes of the two jaws closer together, thus pinching the anatomical structure. This surgical clamping device applies more particularly to the clamping of the aorta.

Abstract: A combined device for plugging and fluidthight puncturing of a wall of a hollow organ, comprising a head bearing a surgical staple for the wall of the hollow organ, a fluidthight puncturing system comprising a puncturing device and a hollow channel, a keeping means for bringing the said staple from its open position to its closed position, a support connected to a traction member extending towards the distal part of the device. The device comprises an introducer capable of introducing the head of the device inside an organism. A staple particularly designed to fit this device is also described.
