Abstract
The invention relates to devices and methods for creating a curvilinear cavity within a vertebral body or other body structure. An example method of forming a void in bony structure includes accessing a bony structure with a cannula, inserting a distal end of a combined drill and reaming device through the cannula and into the bony structure, manipulating the distal end of the combined drill and reaming device to create a void in the bony structure, and removing the distal end of the combined drill and reaming device from the cannula.
Claims8
An apparatus for forming a void in bony structure comprising:
- a handle having at least one lever;
- and
- a flexible drill shaft assembly extending from a distal end of the handle, comprising:
- a pivotable blade located at a distal end of the flexible drill shaft assembly, wherein the pivotable blade is configured to cut in both a non-deployed and deployed position;
- a flexible rotatable drive shaft coupled to the pivotable blade;
- and
- a flexible, moveable and non-rotatable housing,
- wherein the at least one lever in a depressed position is configured to straighten the pivotable blade into the non-deployed position and wherein the at least one lever in a released position is configured to allow the pivotable blade to remain in the deployed position,
- wherein the apparatus includes a ratchet mechanism when engaged to a rotatable knob allows the pivotable blade to only be translated proximally and when disengaged from the rotatable knob allows the pivotable blade to be translated proximally and distally.
