An orthopedic cup impactor for use in minimally invasive hip replacement surgical procedures is described. The impactor comprises a handle, residing at a proximal end portion, and a cup engagement sub-assembly located at a distal portion. A shaft resides therebetween. The shaft portion is designed with a large radius of curvature that provides added clearance when inserting the impactor in obese patients. The cup engagement sub-assembly features a drive train that comprises a series of “U” and “H” joints deigned to provide full rotational motion. The drive train may be designed to be removable from the cup impactor to provide more efficient and thorough cleaning.
