Abstract
The present invention relates to a brace installation instrument placement that is mounted to anchors secured in an animal subject. The installation instrument includes anchor extensions coupled to the anchors. The instrument is movable with respect to the anchors to position a brace in a position more proximate the anchors. The brace can be indexed for insertion at a predetermined orientation with respect to the installation instrument. Methods and techniques for using the installation instrument are also provided.
Claims98
A brace installation instrument, comprising:
- first and second anchor extensions, each having at least one proximal end and at least one distal end for mounting with a corresponding anchor secured to a bony structure;
- and
- a pivoting brace inserter having a proximal end and a distal end, and including support arms mounted adjacent the proximal end of said anchor extensions and a pivot arm extending to a brace mounting portion at the distal end of said inserter, said pivoting brace inserter pivotable about a pivot axis relative to said anchors.
A device for use in a surgical procedure on an animal subject, comprising:
- a pair of anchors securable to the animal subject;
- an installation instrument mountable on said pair of anchors, said installation instrument movable in a fixed geometrical relationship with respect to said pair of anchors;
- and
- a connecting element coupled to said installation instrument, wherein said installation instrument moves said connecting element into a position more proximate to said pair of anchors.

A device for use in a surgical procedure on an animal subject, comprising:
- a pair of anchors securable to the animal subject;
- an installation instrument mountable on said pair of anchors, said installation instrument having a pivot axis in a fixed spatial relationship with respect to said pair of anchors when mounted thereto;
- and
- a connecting element coupled to said installation instrument, wherein said installation instrument is rotatable about said pivot axis to guide said connecting element into a desired position relative to said pair of anchors.

A minimally invasive surgical system, comprising:
- at least a pair of anchors positionable within a body of a patient;
- a connecting element having a geometry configured for connection with the pair of anchors, the connecting element movable between a first position corresponding to a percutaneous insertion position of the connecting element with respect to the body, and a second position within the body, the second position having a predetermined relationship with respect to the position of the pair of anchors;
- and
- an inserter referenced to the pair of anchors, the inserter being operable to move the connecting element along a predetermined path between the first position and the second position.

A minimally invasive surgical system, comprising:
- a connecting element having a predetermined geometry comprising at least a first connector point and a second connector point;
- an instrument having a coupling mechanism for holding the connecting element in a predetermined relationship with the instrument, and wherein the instrument is operable to guide the connecting element along a predetermined path, the predetermined path comprising at least a first path point, a second path point and a third path point, the first path point and the second path point respectively positionable in a predetermined orientation within a body of a patient, the third path point positionable external to the body, wherein the predetermined path comprises a percutaneous insertion path;
- and
- at least a first anchor and a second anchor, the first anchor at a first position corresponding to the first path point and affixable to a first structure within the body, the second anchor at a second position corresponding to the second path point and affixable to a second structure within the body.
