Ancillary automates for inserting and fastening by hooking of an annular body, in particular a emerge, on an annular volume resilient

摘要

The present invention relates to an ancillary (100) automated for inserting and fastening by hooking of an annular body (200), in particular a prosthesis, on a resilient annular volume (23), ancillary (100), which are coaxial about an axis (d), the means of reception and support (8) of said body (200), coaxial with its axis of revolution, the means of radial deployment (500) about said axis (d) of the articulated supports (4) adapted to carry the staples (21), these latter are able to pass through both a thickness of material belonging to such an annular volume (23) and a thickness of material belonging to said annular body (200), under the action of means of longitudinal thrust (600) of said supports (4) with respect to said means of reception and support (8). it is characterized in that it comprises gripping means (300) of the material of the annular volume (23), and means of radial retraction (400) of these latter.
