Cable and crimp for bone surgery
View Patent ↗A surgical cable and crimp device is provided. The cable has an enlargement (bead) affixed to one of its ends. The crimp member includes two holes. One of the holes includes a slot and a cavity. The cavity is sized to accept the bead of the cable, and the slot is sized to receive the flexible cable but not allow the bead to pass through. The other hole is a simple through hole. The cable can be inserted to loop the bone isolated from the crimp member. After the beaded end of the surgical cable is fastened to the crimp, the cable is passed through the simple through hole. The cable is then tensioned by the application thereto of a tensioning tool with the tool applied to the cable and to an abutment face of the crimp member.
1. A method for fixing bone elements, comprising:
looping a flexible cable around a bone, the flexible cable having a first end, a second end, a width, and an enlargement at the first end greater than the width of the cable;
providing a crimp member including:
a first hole having a length, a proximal portion, a distal portion, and a slot running along the length of the hole, the proximal portion of the first hole including a cavity configured and dimensioned to accept the enlargement at the first end of the cable, the slot configured and dimensioned to permit the width of the cable to pass through the slot, and the distal portion of the first hole configured and dimensioned to permit the width of the cable to pass through the distal portion of the first hole and prevent the enlargement from passing through the distal portion of the first hole, and
a second hole having a length, the second hole configured and dimensioned to permit insertion of the second end of the cable through the second hole;
inserting the enlargement at the first end of the cable into the first hole of the crimp member and the width of the cable through the slot in the first hole of the crimp member;
pulling the flexible cable through the first hole of the crimp member so that the flexible cable emerges from the distal portion of the first hole and the enlargement remains within the first hole;
passing the second end of the flexible cable through the second hole of the crimp member; and
tensing the flexible cable to secure the bone.
2. The method of claim 1 , wherein the flexible cable is inserted into a patient and around the bone prior to attachment to the crimp member.
3. The method of claim 1 , wherein the first and second holes of the crimp member are parallel straight holes.
4. The method of claim 1 , wherein the first and second holes of the crimp member are coplanar.
5. The method of claim 1 , wherein the proximal portion of the first hole defines a first axis and the distal portion of the second hole defines a second axis, and the first and second axes are not collinear.
6. The method of claim 1 , wherein the proximal portion of the first hole is coplanar with the second hole.
7. The method of claim 1 , wherein the distal portion of the first hole is substantially parallel to the second hole.
8. The method of claim 1 , wherein the first and second holes of the crimp member are not parallel.
