  • Patent number: 10568631
    Abstract: The head of a stapler for mucosectomy comprises an external goblet-shaped body (1) wherein an internal goblet-shaped body (2) is concentrically and slidingly located, at the edge of which a circular blade (3) is fixed. The internal goblet-shaped body (2) is provided with a central hole (5) wherein a rod (6) is slidingly inserted, at the end (7) of which an anvil (8; 8?) is fixed. One or more annular grooves (11), which are parallel and suitably spaced one from the other, are formed on the lateral surface of the rod (6) perpendicularly to the axis thereof. Said grooves (11) are intended to receive a portion of mucosa (9a) which is included in a purse string suture as the mucosa is tied around the rod (6). By retracting the rod (6) in the central hole (5) of the stem (2a) of the Internal goblet-shaped body (2) the mucosa to be removed is carried into the internal goblet-shaped body (2).

  • 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.
