A metal and/or plastic hand-held manual surgical instrument designed to position an orthopaedic implant within the body by transmission of an impact force that drives the implant into its final position. The proximal end of the instrument is a handle usually designed to absorb the impact from a surgical hammer or mallet, and the distal end is usually shaped to conform to the implant shape (flat or anatomically curved) or is shaped like a chisel handle to facilitate implant positioning. This is a single-use device.
