Tether clamp and implantation system
View Patent ↗A clamp housing assembly and method for providing stabilization as a bone anchor during an operation. The assembly includes a housing, a locking element and a band. The housing defines a longitudinal axis, a center recess, and at least one slot. The housing has two opposing arms extending from a base. At least a portion of the inside surface of each arm may be threaded and at least a portion of the outside surface of each arm may be planar. The locking element is positionable within the recess in a co-axial relationship to the housing. The band is sized for travel along a predetermined path defined in part by the at least one slot in the housing.
1. A method of securing a clamp assembly comprising:
providing a clamp assembly including a housing, a locking element, a band, and a surgical rod;
positioning the housing at a targeted location adjacent a bone;
wrapping the band about the bone and about the housing, the band along a predetermined path;
positioning the surgical rod within the housing;
inserting the locking element within the housing to surround the rod;
engaging a tensioning instrument onto the clamp assembly;
inserting the band through a carriage of the tensioning instrument;
manipulating the tensioning instrument to move the carriage, whereby the band is tightened about the bone; and
locking the locking element into the housing, wherein said locking includes inserting a locking tool through the tensioning instrument and engaging the locking element with the locking tool.
2. The method of claim 1 wherein the surgical rod is positioned within the housing with at least a portion of the band between the housing and the surgical rod.
3. The method of claim 2 , wherein said locking includes driving the locking element toward the surgical rod and the housing.
4. The method of claim 1 , wherein the clamp assembly includes a mounting pin mounted to the clamp assembly, wherein one end of the band is mounted to the mounting pin.
5. The method of claim 4 , further comprising inserting the band through at least one slot in the housing.
6. The method of claim 1 , further comprising attaching the band to the housing prior to said inserting.
7. The method of claim 6 , wherein said attaching includes mounting the band to a pin and mounting the pin to the housing.
8. The method of claim 1 further comprising provisionally locking the locking element into the housing prior to engaging the tensioning instrument.
9. The method of claim 1 wherein the locking element is inserted into the housing along a common longitudinal axis.
10. The method of claim 1 wherein the tensioning instrument is engaged with the spinal clamp assembly along a common longitudinal axis.
11. The method of claim 1 , wherein said manipulating includes rotating a threaded member attached to the carriage to move the carriage.
12. The method of claim 1 , wherein said locking includes compressing the surgical rod and the band between the locking element and the housing.
13. A method of securing a clamp assembly comprising:
providing a clamp assembly including a housing, a locking element, a band, and a surgical rod;
positioning the housing at a targeted location adjacent a bone;
wrapping the band about the bone and about the housing;
positioning the surgical rod within the housing;
inserting the locking element within the housing to surround the rod;
provisionally locking the locking element into the housing;
engaging a tensioning instrument onto the clamp assembly;
inserting the band through the tensioning instrument;
manipulating the tensioning instrument to tighten the band about the bone; and
locking the locking element into the housing.
14. The method of claim 13 , wherein the clamp assembly includes a mounting pin mounted to the clamp assembly, wherein one end of the band is mounted to the mounting pin.
15. The method of claim 14 , further comprising inserting the band through at least one slot in the housing.
16. The method of claim 13 , wherein said locking includes inserting a locking tool through the tensioning instrument and engaging the locking element with the locking tool.
17. The method of claim 13 , wherein the locking element is inserted into the housing along a common longitudinal axis.
18. The method of claim 13 , wherein the tensioning instrument is engaged with the spinal clamp assembly along a common longitudinal axis.
19. The method of claim 13 , wherein the surgical rod is positioned within the housing with at least a portion of the band between the housing and the surgical rod.
20. The method of claim 13 , wherein said manipulating includes rotating a threaded member attached to the carriage to move the carriage.
