Cable fixation device

A counter torque locker for securing a surgical cable within a clamp housing comprising:

• a cable clamp housing;
• a lock of a cable fixation device;
• an elongated clamp base with an extended control arm for alignment with said cable clamp housing;
• a cannulated worm shaft at least partially housed within said clamp base;
• said cannulated worm shaft comprising a drive boss formed thereon for engagement with a lock of said cable fixation device;
• a worm gear situated on said cannulated worm shaft;
• a worm rod oriented generally perpendicular to said worm shaft and at least partially housed within said clamp base;
• a worm helix formed on said worm rod;
• wherein said worm helix is meshed with said worm gear.

A cable fixation device for securing bone segments comprising:

• a clamp housing;
• a surgical cable;
• said surgical cable having a butt;
• a drum channel situated within said clamp housing for securing said butt within said drum channel;
• a lock aperture within said clamp housing;
• a collet housed within said lock aperture;
• a lock cap housed within said lock aperture;
• said surgical cable formed into a cable loop with a portion of said cable residing within said collet;
• wherein said cable butt, said cable loop, said collet, and said lock cap reside in a single plane.

A cable fixation device for securing bone segments comprising:

• a clamp housing;
• a surgical cable;
• said surgical cable having a butt;
• a drum channel situated within said clamp housing for securing said butt within said drum channel;
• a lock aperture within said clamp housing;
• a collet housed within said lock aperture;
• a lock cap housed within said lock aperture;
• said surgical cable formed into a cable loop with a portion of said cable residing within said collet;
• wherein said drum channel and said lock aperture intersect.

A cable fixation device for securing bone segments comprising:

• a clamp housing;
• a collet housed within said clamp housing;
• a lock cap housed within said clamp housing;
• a surgical cable;
• a butt end of said cable secured in said clamp housing;
• said surgical cable formed into a cable loop with a portion of said cable residing within said collet and said lock cap;
• and gliding surfaces between said lock cap and said collet for minimizing twisting of said cable when advancing said lock cap.

A surgical cable fixation kit comprising:

• an implantable cable;
• a clamp housing;
• a lock for advancement into said clamp housing;
• a collet compressible about said cable;
• a counter torque locking instrument comprising a worm shaft for advancing said lock cap;
• and a worm rod generally perpendicular to said worm shaft for transmitting torsional forces on said worm rod to said lock cap.
