It is intended for application of two-row staple suture and two-level staple suture using metal staples. It can be used at gastric resection, for closure of duodenal, small and large intestines with peritonization of their ends, and for suturing of lung and other tissues.
At application of two-row staple suture a tissue or an organ in the prospective stitching zone is compressed by the matrix and the cartridge to the stitching clearance and pierced by the staples which legs, getting to the matrix small cavities, are bent to B-shaped form. At application of two-level staple suture consisting of two-row and one-row, the tissue or the organ in the prospective stapling zone is compressed by the matrix and the cartridge to the stitching clearance, it is fixed to the device by two needles and is pierced by the staples which legs, getting to the small cavities, are bent to B-shaped form. Then the removed part of the tissue is cut away, the matrix and cartridge planes are separated, two-row suture is immersed, the matrix and cartridge planes are put together with the minimum clearance, the second one-row suture is made. The suturing apparatus УТО-70 is of high functionality – the thickness of the hook of the suturing apparatus brought under short part of the organ being stitched in a narrow tunnel, can be decreased (by the way of removal of demountable part of the wedge), so the suturing apparatus УТО-70 can be used as УО type suturing apparatus for organs.
