Abstract
A system for securing a spinal rod to a bone structure using a connector is provided. The connector functions by modulating friction on a band in two band channels and locking the spinal rod in a separate rod channel. An instrument is also provided for tensioning the band.
Claims20
A device for tensioning a band connected to a connector, the device comprising:
- an elongate shaft having a distal end and a proximal end;
- an engagement feature at the distal end of the elongate shaft, the engagement feature configured to engage the connector;
- and
- a band holder comprising a band connection ring having two band slots configured to receive the band and a band locking ring having two indentations, wherein, in a first configuration of the band holder, each of the two indentations is aligned with a respective one of the two band slots to allow the band to pass through one of the two band slots, and in a second configuration of the band holder, each of the two indentations is rotated relative to the respective one of the two band slots to restrict movement of the band.

- an engagement feature at the distal end of the elongate shaft, the engagement feature configured to engage the connector;
- and
- a band holder comprising a band connection ring having two band slots configured to receive the band and a band locking ring having two indentations, wherein, when the band locking ring is rotated such that the two indentations are not aligned with the two band slots, longitudinal translation of the band relative to the band holder is restricted or prevented.
