Closed channel anchor device for bone implantation during surgical procedures

An anchor device for insertion into a bone, comprising:

• a post suitable for implantation into a bone, and
• a cord housing coupled to the post, comprising:
• a pair of cord channels comprising a first cord channel extending through the housing and a second cord channel extending through the housing;
• a cavity open from a top surface of the housing, the cavity comprising a socket extending into the housing, the socket comprising:
• socket threads for receiving a threaded fastener,
• a first socket aperture opening into the first cord channel, and
• a second socket aperture opening into the second cord channel;
• the socket threads disposed to allow a threaded fastener, comprising fastener threads, to be threaded into the socket and
• protrude into the first socket aperture to enter the first cord channel such that the fastener threads press against a first cord inserted through the first cord channel and at least partially compress the first cord against an opposing inner wall of the first cord channel, and
• protrude into the second socket aperture to enter the second cord channel such that the fastener threads press against a second cord inserted through the second cord channel and at least partially compress the second cord against an opposing inner wall of the second cord channel, and
• hold each of the cords within their respective cord channel,
• further comprising a threaded fastener comprising fastener threads mated to the socket threads, wherein the socket terminates at a stop against which the threaded fastener is tightened to hold each of the cords within their respective cord channel, wherein the threaded fastener comprises means for biasing the threaded fastener within the socket.

• a cord housing coupled to the post, comprising:
• a cord channel extending through the housing,
• a cavity open from a top surface of the housing, the cavity located adjacent the cord channel, the cavity comprising a socket extending into the housing, the socket comprising:
• socket threads for receiving a threaded fastener, and
• a socket aperture opening into the cord channel;
• the socket threads disposed to allow a threaded fastener, comprising fastener threads, to be threaded into the socket and
• protrude into the socket aperture to enter the cord channel such that the fastener threads press against a cord inserted through the cord channel and at least partially compress the cord against an opposing inner wall of the cord channel, and
• hold the cord within the cord channel;
• further comprising a threaded fastener comprising fastener threads mated to the socket threads, wherein the threads of the threaded fastener comprise sharp crested threads near a tip of the fastener, rounded crested threads in a middle portion of the fastener, and sharp crested threads near a head of the fastener.
