Orthopedic surgical pin positioning device
Abstract:
An orthopedic drill guide and surgical pin positioning device includes a primary surgical pin for insertion into a fractured bone and a longitudinal drum supported on said primary surgical pin. A set screw is also provided in said longitudinal drum for preventing the longitudinal drum from rotation about the primary surgical pin. A transverse drum is also provided and is rotatably disposed in the longitudinal drum as is a set screw for fixing the position of the transverse drum with respect to the longitudinal drum. A secondary pin extends through the transverse drum and is fixed in a second position on the hard tissue of the fractured bone. Finally, a pair of aligned openings extends through the transverse drum for guiding a drill bit and locating a surgical pin within the broken bone.
