Surgical instrumentation

摘要

The system (1) has an ancillary unit (10) carrying a blocking unit (20) to block axial translation of a guiding rod (13) relative to a through hole (12). An elongated body (22) of a wedging part (21) of the blocking unit is elastically deformable between rest and deformed configurations by passing via an intermediate configuration in which the rod is received in the hole. A bearing surface (25A) delimited by an embossment (25) is pressed against the rod along a direction transverse to a central axis (Z-Z) by elastic return of the body from the deformed configuration to the rest configuration.
