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 secured to the animal subject;
- an installation instrument mounted 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 secured to the animal subject;
- an installation instrument mounted on said pair of anchors, said installation instrument having a pivot axis in a fixed spatial relationship with respect to said pair of anchors;
- and
- a connecting element coupled to said installation instrument, wherein said installation instrument is rotated about said pivot axis to guide said connecting element into a desired position relative to said pair of anchors.
A device for use in a surgical procedure on an animal subject, comprising:
- an installation instrument coupled to a brace, said brace having an indexed portion coupling said brace in a predetermined orientation with respect to said installation instrument.
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 an anchor securable to a bony structure;
- a brace inserter having a proximal end and a distal end, said brace inserter mounted to said first and second anchor extensions at said proximal end of said anchor extensions, said brace inserter movable about a pivot axis;
- and
- a brace releasably coupled to said distal end of said brace inserter.
A device for use in a surgical procedure on an animal subject, comprising:
- at least one anchor secured to the animal subject, said anchor including a set screw having a break-off portion;
- and
- an instrument mounted on said anchor movable to position a brace relative to said anchor, said instrument being released from said anchor when said break-off portion is severed from said set screw.
A method of installation of an orthopedic brace in an animal subject, comprising:
- placing first and second anchors mounted on first and second anchor extensions, respectively, in first and second bony parts of the body;
- mounting a brace inserter of an installation instrument on the first and second anchor extensions, the installation instrument having a pivot axis relative to the anchors;
- swinging the brace inserter relative to the anchors about the pivot axis and thereby moving the brace through an arc centered on the pivot axis of the instrument;
- and
- introducing an end of the brace to the location of the anchors.
A method of installation of a connecting element in an animal subject, comprising:
- placing first and second anchors in first and second bony parts of the body;
- mounting an installation instrument on the first and second anchors, the installation instrument having the connecting element secured thereto;
- and
- moving the installation instrument to position the connecting element more proximate the first and second anchors.
A method of installation of a brace in an animal subject, comprising:
- placing first and second anchors mounted on first and second anchor extensions, respectively, in first and second bony parts of the body;
- mounting a brace inserter on the first and second anchor extensions;
- and
- guiding the brace into a desired position relative to the anchors with the brace inserter.
A method for stabilizing at least one vertebral level of an animal subject, comprising:
- inserting at least one interbody fusion device in the disc space between the vertebrae;
- engaging first and second anchors to corresponding ones of the vertebrae through first and second percutaneous punctures in the subject;
- mounting an installation instrument on the first and second anchors;
- and
- positioning a brace proximate the first and second anchors through a third percutaneous puncture in the subject using the installation instrument.
