ORTHOPEDIC TAMP AND BONE STABILIZATION MATERIAL DELIVERY DEVICE

摘要

An orthopedic bone tamp and bone stabilization material delivery device is operable to reduce depressed bone fragments to an elevated position and concurrently introduce to the fracture zone bone stabilization material so as to stabilize the newly positioned fragment. A bone tamp comprising a cannula having a tubular wall with outside diameter and inside diameters and defining a distal and proximal ends includes a bone displacement face associated with the closed distal end. A lumen defined by the walls of the cannula extends from the proximal end and terminates at the distal end face where it is associated with several apertures. The displacement face of the cannula is configured to operably manipulate and reduce bone fragments to an elevated position while the apertures and lumen can concurrently deliver to the fracture zone a bone stabilization material.

1. A bone tamp for use in surgical procedures, the tamp comprising:
a cannula having a tubular wall with an outside diameter and an inside diameter, a distal end, and a proximal end, wherein the distal end is closed and includes a bone displacement face with a bone displacement face diameter substantially equal to the outside diameter of the cannula; a lumen defined by the tubular wall of the cannula traversing through the proximal end and terminating at the distal end at the bone displacement face; and a plurality of apertures within the tubular wall proximate to the distal end and fluidly connected to the lumen.
