<p>An orthopedic impactor device (50) for positioning an orthopedic prosthetic cup implant during a hip replacement surgery is described. The impactor is designed with a "one piece" elongated body portion (60), having a distal prosthetic cup engagement portion (66) which is separated from a proximal strike plate (58) by an annular sidewall (68). A handle portion (64) is positioned circumferentially around the annular sidewall of the elongated body in a slidable relationship along a longitudinal axis. A rod (62), connectable to an orthopedic prosthetic cup, is positioned within a cavity (70) of the body and connected to the proximal ring. A lever arm (108) having a distal wedge portion (122) is pivotally connected to the handle portion such that when the lever arm is pivoted towards the annular sidewall of the handle portion, the distal end of the rod moves within the body cavity. This rod movement within the body cavity enables a prosthetic cup to be selectably connected and disconnected from the rod distal end for insertion into a body during a surgical procedure.</p> |
