Further, the aiming link block is fixed on handle by guide rod lockwheel, and the guide rod passes through guide rod
Lockwheel, which is fixed on, to be aimed on link block, and distal end diopter is fixedly mounted by guide rod lockwheel in the other end.
In order to preferably install intramedullary nail, make installation elasticity of the intramedullary nail on handle just, the utility model also wraps
Tight-hanged screw is included, the lower part of the handle is connect by tight-hanged screw with intramedullary nail.
The beneficial effects of the utility model are: the seal wire of the utility model is oriented to hollow lock screw intramedullary nail tool, packet
It includes handle, intramedullary nail, aim at link block and guide rod, the lower part of the handle connects intramedullary nail, and top connection aims at link block, institute
It states guide rod to connect with the aiming link block, the other end is connected with distal end diopter, fixed peace on the distal end diopter
Equipped with the first sheath, bone conduction draw pin is equipped in first sheath, the bone conduction draw pin wears the positioning on the intramedullary nail
Hole is equipped with hollow lock screw in the bone conduction draw pin, at the distal end of fixed intramedullary nail, first squeezes into bone conduction draw pin in marrow
The positioning hole of nail, bone conduction draw pin is thinner, is easy to position and squeeze into, hollow locking spiral shell is then squeezed under the guiding of bone conduction draw pin
Nail, bone conduction draw pin provide positioning and guiding effect for hollow lock screw, save operating time, reduce bleeding.
