| 摘要 |
The invention concerns a gastroplasty ring comprising attachments (1d) for securely linking the ring with sutures (3) to said gastric wall, after the ring has been deformed. The diameter of the passage between the two resulting pouches is adjusted with sutures (4) inserted in the ring and tied up at each end of said ring, after calibrating element (CA) has been introduced through the oesophagus. The longitudinal orifice (1b) of the tube provided in the thickness of the ring communicates with a central orifice (1c) produced from the generatrix opposite the flat part (1a), so as to insert the non-absorbable sutures (4) tied up or otherwise attached at the rear ends at said orifice and emerging at the ends of the ring so as to be tied to fix said ring in position.
