Abstract
Device for fixing a bony structure to a support member, the device comprising a first connecting member which comprises: a main body provided with a first passage configured for receiving the support member, and with a first opening configured for passing a flexible member therethrough; and a rod fixed to and/or monobloc with the main body and protruding therefrom. The device further comprises a first flexible member passing through the first opening of the main body and extending beyond the main body for attachment to the bony structure.

A fixing device for fixing a bony structure to an elongate support member and a first flexible member, the fixing device comprising:
- a first connecting member which comprises:
- a main body provided with a first passage configured for receiving the elongate support member along a first axis, and with a first opening configured for passing the first flexible member therethrough, and
- a rod extending from the main body and protruding therefrom along a second axis, and
- at least one clamping mechanism for simultaneously clamping the elongate support member and the first flexible member together within the main body,
- wherein the first axis of the first passage passes through the main body in a first direction and wherein the second axis of the rod extends in a second direction, wherein the second axis is substantially parallel to and laterally offset from the first axis.
A system for stabilizing a bony structure with an elongate support member and a first flexible member, the system comprising:
- a fixing device comprising:
- a first connecting member including a main body provided with a first passage configured for receiving the support member, a first opening configured for passing the first flexible member therethrough, and a first rod extending from the main body and protruding therefrom, and
- a hinge member disposed within the main body to form a clamping mechanism configured for clamping the elongate support member and the first flexible member together within the main body,
- wherein the first passage passes through the main body in a first direction and wherein the rod extends in a second direction substantially parallel to and laterally offset from the first direction;
- and
- a first anchor coupled to the first rod, the first anchor configured to affix to the boney structure;
- a second fixing device comprising:
- a second connecting member including a main body provided with a second passage configured for receiving the support member,
- a second opening configured for passing a second flexible member therethrough, and
- a second rod extending from the main body and protruding therefrom, and
- a second anchor for affixing to the bony structure,
- wherein the support member is U-shaped and defines two branches, and
- wherein the first and second connecting members are adapted to receive the two branches, respectively.
A fixing device comprising:
- a rod extending along an axis;
- and
- a clamp connected to the rod offset from the axis such that the rod protrudes from the clamp, the clamp comprising:
- an upper member comprising:
- a first clamping surface on an inner surface of the upper member;
- and
- a first ligature socket extending through the first clamping surface transverse to the axis;
- a lower member comprising:
- a second clamping surface on an upper surface of the lower member, the second damping surface disposed opposite the first clamping surface;
- and
- a second ligature socket extending through the second clamping surface transverse to the axis, the second ligature socket disposed opposite the first ligature socket;
- and
- a hinge pivotably connecting the upper member and the lower member.
