Claims23
A device for reducing a rod into a head of an implant, said device comprising:
- an implant having a bone engaging portion connected with a generally U-shaped head having a core including a generally U-shaped channel extending transversely therethrough and defined by generally parallel side walls and a bottom wall, said U-shaped channel sized and configured for receiving said rod;
- a rotating member rotatably engaged with the head of the implant in a non-threaded manner;
- and
- a ram for reducing said rod into said U-shaped channel of said implant head core, said ram being threadably engaged with said rotating member while being restrained from rotation and being moved by rotation of said rotating member.
A method for reducing a stabilization member into a head of a medical implant, said implant having a bone engaging portion connected with a head having a core for receiving said stabilization member, said method comprising:
- providing a rotating member;
- threadably engaging a ram with said rotating member;
- torquing said rotating member to rotate said rotating member relative to said implant head to threadedly engage the rotating member along said ram while rotatively restraining said ram to prevent rotation of said ram to thereby move said ram to reduce said stabilization member into said implant head.
A device for reducing a rod into a head of an implant, said device comprising:
- an implant having a bone engaging portion connected with a generally U-shaped head having a core including a generally U-shaped channel extending transversely therethrough and defined by generally parallel side walls and a bottom wall, said U-shaped channel sized and configured for receiving said rod;
- a rotating member rotatably engaged with the head of the implant in a non-threaded manner;
- and
- a ram for reducing said rod into said U-shaped channel of said implant head core, said ram being threadably engaged with said rotating member while being restrained from rotation and being moved by rotation of said rotating member, wherein said ram includes a rod engagement head positioned within said U-shaped channel of said implant and configured to engage said rod to reduce said rod along said U-shaped channel.
