1. A bone cement kit comprising:
a needle comprising a trocar and a stylet; said trocar for injecting a bone cement into a bone and having a hollow duct extending between an open tip and a handle, said handle having an opening communicating with an interior of said hollow duct, said stylet receivable within said hollow duct to provide a solid instrument for piercing bone; a delivery reservoir for holding said bone cement, having a first distal tip with threads along a surface of said first distal tip; a connecting tube having a proximal end with threads along a surface of said proximal end, and a distal end opposite said proximal end with additional threads connecting to said trocar for injecting said bone cement into a bone; a connector joining said first distal tip to said connecting tube, said connector having a first end with threads complementary to said threads of said first distal tip, and a second end with threads complementary to said threads of said proximal end of said connecting tube; said handle opening having threads complementary to said additional threads of said connecting tube, for connecting said distal end of said connecting tube to said opening after removal of said stylet from said hollow duct; wherein said first distal tip, said connector, said connecting tube, said opening, said hollow duct and said open tip are configured with uniform internal dimensions so as to provide a uniformly dimensioned pathway for said bone cement to travel from said first distal tip through to said open tip. |
