Minimally-invasive device, kit, and method for harvesting bone graft

摘要

A minimally-invasive bone graft harvesting device, kit, and method are provided. The device includes a hollow cutting element and an extraction element. The hollow cutting element may define a longitudinal axis and includes a distal end, a proximal end adapted to be coupled to a powered or manual-operated rotary tool, and an inner lumen extending longitudinally between the distal and proximal ends. The hollow cutting element may also include one or more blades protruding from an outer surface of the cutting element. Each blade may be arranged adjacent to an opening extending between the outer surface and the inner lumen to allow cancellous bone material cut by each blade during use to pass through the opening into the inner lumen. The extraction element may be removably received within the inner lumen of the hollow cutting element to allow withdrawal of the bone material in the inner lumen.

1. A minimally-invasive bone graft harvesting device, comprising:
a hollow cutting element defining a longitudinal axis and including:
a distal end;a proximal end adapted to be coupled to a powered or manual-operated rotary tool;an inner lumen extending longitudinally between the distal and proximal ends; andone or more blades protruding from an outer surface of the cutting element, wherein each blade is arranged adjacent to an opening extending between the outer surface and the inner lumen to allow cancellous bone material cut by each blade to pass through the opening into the inner lumen; an extraction element within the inner lumen of the hollow cutting element to allow withdrawal of the bone material in the inner lumen; a bone material collection canister, wherein the cutting element extends through the canister; and a deflection element arranged within the canister and adjacent to a hole in the outer surface of the cutting element to remove cut bone material from within the inner lumen when the extraction element is moved proximally.
