OSTEOSYNTHESIS SCREW WITH REDUCED RADIAL COMPRESSION |
| 摘要 |
The invention concerns an osteosynthesis screw (1) formed from a core (2) externally provided with a helical thread (3), said screw comprising a distal penetration portion and a proximal portion forming the head of the screw (6) and having a conical longitudinal section characterised in that the proximal portion comprises annular notches which are formed in the thickness of the core (2) and in the gaps between the threads of said proximal portion in such a way as to reduce the radial pressure during screwing.—Surgical device. |

1. An osteosynthesis screw (1) formed by a core (2) provided externally with a helical thread (3), said screw having a distal penetration portion (4) and a proximal portion (5) forming the screw head (6) and having a conical longitudinal section, the screw being characterized in that the proximal portion (5) includes circular notches (12) that are formed in the thickness of the core (2) and in the inter-thread gaps (13) of said proximal portion (5) so as to reduce radial pressure during screw tightening. |
