Patent ID: 7189236

Claim:
A vertebral arthrodesis equipment, comprising: two shoring rods adapted to be placed parallel to each other on either side of vertebrae to be treated; anchoring members to attach said rods to the vertebrae; at least one two-part cross-piece; and attachment members to attach said two-part cross-piece to said shoring rods, each attachment member comprises a one-piece member, wherein, each one-piece member comprises: a recess crossing said one-piece member and forming two lateral clamping walls for receiving and tightening around a shoring rod; an L-shaped slot running in the same direction as said recess, such that said L-shaped slot has a part roughly parallel to said clamping walls that opens laterally into said recess and a part roughly perpendicular to said clamping walls; said perpendicular part of said L-shaped slot being sufficiently long, so that each clamping wall is connected to said one-piece member by a section sufficiently narrow to provide elasticity; and two coaxial bores, wherein a first non-threaded bore passes through a first part of said one-piece member, defined by a surface of said one-piece member opposite said recess and by said L-shaped slot part perpendicular to the clamping walls, and a second threaded bore passes through a second part of said one-piece member, defined by the L-shaped slot part perpendicular to the clamping walls and by the recess.
