Abstract
An orthopedic surgical kit for inserting a biological material into the cancellous portion of bone by a minimally invasive technique has several components which are manually operated using a universal handle. The kit includes a docking needle used as a guide for placing a cannula in a bone. The cannula is filled with a biological material, for support or treatment of the bone, and the material is expressed from the cannula by a plunger.
Claims19
A surgical kit for orthopedic procedures comprising a docking needle for penetration of the soft tissue of the body and lodgement in a bone, a cannula having a sharpened leading end, a trailing end for carrying a connector, and a bore of sufficient size to telescope over said needle, a plurality of connectors, and a tool for sequential manipulation of said needle and said cannula, said tool having a center portion and a periphery, a first slit in said tool between said periphery and said center portion, said first slit having a first jaw and a second jaw opposed to said first jaw, said first and second jaws pivoting about said center portion, said first jaw having a first bore therethrough, said second jaw having a bore therethrough, said first bore and said second bore being aligned when said first and second jaws are closed, said first and second bores intersecting when said first and second jaws are open whereby said docking needle may pass through said aligned bores and be frictionally bound by said intersecting bores to grip said needle for removal.
A surgical kit for delivering a biological substance within the cancellous portion of a bone comprising a docking needle having a sharp end and a trailing end, a delivery cannula having a leading end, a bore sized to telescope over said needle and a trailing end with a connector, a plunger having a smaller diameter than said bore and a length to extend through said cannula to said leading end for delivery of a biological substance, and a handle for sequentially manipulating said docking needle, said delivery cannula, and said plunger, said handle having a center portion and a periphery, at least one slit in said handle between said periphery and said center portion, said slit having opposite surfaces, said opposite surfaces defining a receiver for said connector, said receiver preventing rotation of said cannula in said handle.
