Abstract The present invention is a surgical bone brush which provides a means to remove soft tissue from harvested autogenous and allografts bone prior to implantation of the bone into the human body. The invention is a surgical instrument with multiple fibers of surgical grade stainless steel or implantable material, wherein the fibers are held in place around a retaining ring, by a cap assembly, and extend outward forming a brush. The bone brush head, provided in a plurality of sizes and shapes, is attached at one end of a shaft, of a length and diameter providing for the insertion of the shaft into surgical grade rotary hand pieces. The bone brush provides a means to remove soft tissue from bone, decorticate, and contour bone. This is achieved when the shaft of the bone brush is inserted into a surgical rotary hand piece and the hand piece is activated thereby causing the brush head to rotate. When the fibers of the bone brush are placed into contact with the soft tissue covering bone, the rotary action of the brush head removes the soft tissue from the bone. Decortication and bone contouring are achieved in the same manner.
A method of preparing host and graft bone surfaces during a surgical bone graft procedure, the method comprising the steps of: providing a rotary bone brush device comprised of materials suitable for use within human body during surgical procedures, the bone brush device comprising a shaft, a brush head including a plurality of fibers arranged for rotary engagement with a bone, and a brush cap assembly mounted on the shaft, the brush cap assembly including a locking ring that secures the plurality of fibers around the shaft, the rush cap assembly also including a top locking cap and a bottom locking cap which are attached to the shaft and secure the locking ring and the plurality of fibers; causing the device to rotate; applying the device to a surface of a bone; moving the device along the bone during rotation of the device to remove soft tissue from the bone; moving the device along the bone during the rotation of the device to decorticate cancellous bone; and moving the device along the bone during the rotation of the device to contour the bone.
