(5) Integrated interlocking screw insertion: After confirming the position of the main nail, a longitudinal skin incision was made at the entry site of the lag screw, and the lag screw drill sleeve
Abstract: Compensation of variable force performed by a spring can be compensated by a flat cam, for example by operating a drill sleeve
. For the construction of the mechanism it is essential to coordinate the movement path and to choose the appropriate possible rigidity of spring with regard to the required force and to the constant required torque
The working prototype consists of a fixed magnet that is placed inside the intramedullary nail and a handheld unit housing the sensors, electronics, and drill sleeve
. The target magnet is located on the end of a wand inside the hollow nail.
The drilling part of drill bit unexposed by drill sleeve
is measured as distance X mm.
Then take two sets of drill sleeves
and 3 mm steinmenn pins and place it in the zig and lock the proximal holes in the external nail as shown in the figure.
