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, when the two indentations are in a first position relative to the two band slots, the band is configured to pass through the two band slots, and when the two indentations are in a second position relative to the two band slots, longitudinal translation of the band relative to the band holder is restricted.
A device for inserting a connector to a spinal rod and for tensioning a band connected to the 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 is configured to reversibly 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 the engagement feature comprises a ramped contour that is wider in a distal direction, a boot element configured to translate longitudinally relative to the elongate shaft, a detent member configured to translate longitudinally and radially relative to the ramped contour.
A device for inserting a connector to a spinal rod and for tensioning a band connected to the connector:
- 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 reversibly 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 two indentations and the two band slots are aligned, the band is configured to pass freely through the two band slots, and when the two indentations and the two band slots are not aligned, longitudinal translation of the band relative to the band holder is restricted or prevented, and
- wherein the band is positioned around a bone structure and reversibly connected to the connector.
