  • Patent number: 8449563
    Abstract: Fragmentable compression device for the anastomosis of hollow organs consisting of a pot-shaped body composed of two elements (1, 2), inserted one into the other and consisting of a plurality of composable sectors (5, 6), a third ring-shaped or hollow cylinder-shaped element (3) intended to be inserted into said pot-shaped body to clamp the edges of the organs to be anastomized, and a fourth element (4) also ring-shaped or hollow cylinder-shaped which is pressure-inserted into element (3) to compress said edges. Also elements (3, 4) consist of a plurality of composable sectors (7, 8). The axial dimension of the device is notably short so that, when it is applied in the vicinity of the anal canal of the patient, tenesmus is considerably reduced.

  • Patent number: 8337401
    Abstract: A composite anoscope for ano-rectal diagnostic and surgery, wherein the anoscope (2) also comprises an internal component (1), to be inserted therein, and a suitably shorter external component (3), ending with a conic frustum mantle (18), wherein the anoscope (2) is to be inserted. The three components (1, 2, 3) are all conic frustum shaped hollow bodies having circular cross-section. The internal component (1), when inserted in the anoscope (2), forms therewith a single body having a compact and smooth external surface and an ogival tip. The external component (3) is provided close to its mouth with slotted wings (19, 20), to be fixed to the perianal skin for securing the whole composite anoscope during the diagnostic and surgical operations.

  • Patent number: 5290298
    Abstract: A fragmentable compression device for the anastomosis of hollow organs of the human body comprising free cylindrical members that are composed of sectors. The edges of the hollow organs to be anastomosed are compressed between the first and second members by means of the third member, which presses the second member against the first one. The first member is in turn composed of a first and second sub-members, said sub-members being composed of sectors the second one of said sub-members being locked within the first one by means of teeth that are present on the outer surface of the second sub-member, said teeth being inserted into notches that are carved out of the internal surface of the first sub-member.

  • Patent number: 4966602
    Abstract: A compression device for the anastomosis of hollow organs comprising three members having a hollow cylinder shape suitable to compress the edges of the hollow organs that are to be anastomosized. Each one of these members is formed by sectors that remain solidly connected to one another until the edges of the hollow organs are present, and separate into fragments when the edges break off from the seat of anastomosis, as they, necrotizing, lose their consistency.

  • Patent number: 4915107
    Abstract: This invention relates to an automatic instrument for purse-string sutures for surgical use, comprising two toothed jaws provided with openings having side slots for through passage of the needles carrying the ends of a suture thread fastened thereto. Said jaws are integral with a pair of support members adapted to be opened in order to be able to introduce the part to be sutured therebetween. Said support members carry a pair of flexible wires having one end wound around a pair of coaxial drums controlled by means of a knob, while the opposite ends are each connected to a needle, in such a way that by actuating the knob, the flexible wires unwind from the drums and push the needles through the jaw openings all the way to make the needle ends to project out of the ends of the jaws.

  • Patent number: 4681108
    Abstract: A mechanical gun for circular anastomosis of hollow organs by which the elements of a particular suturing device are engaged one into the other compressing between their walls the tissue edges of two resected hollow organs. The gun also comprises a circular cutting member which trim outside the compression area inside the device the edges of the compressed tissues, and then releases the circular mechanical gun from the suturing device which will be maintained until a natural suture forms between the connected hollow organs.

  • Patent number: 4598712
    Abstract: A new device for the anastomosis of hollow organs to be used by means of a suitable mechanical circular anastomotic gun, is described consisting essentially in three elements fixed one inside the other, and compressing between two of them the tissue edges of the hollow dissected organs, thus enabling the natural sealing of a suture between the organs themselves.
