Abstract
An instrument for inserting an implant between vertebral bodies, including a holder adapted to hold the implant during insertion of the implant between the vertebral bodies, a retractor adapted to retract the holder away from the implant after the insertion, and a guard adapted to prevent the implant from being removed from between the vertebral bodies during the retraction.
Claims17
An instrument for inserting an implant between vertebral bodies, comprising:
- a holder adapted to hold the implant during insertion of the implant between the vertebral bodies;
- a retractor adapted to retract the holder away from the implant after the insertion;
- and
- a guard adapted to prevent the implant from being removed from between the vertebral bodies during the retraction;
- wherein the refractor comprises a coupling adapted to couple the holder to the guard and by which relative movement between the holder and the guard is effectable during the refraction.

An instrument for inserting an implant between vertebral bodies, comprising:
- a holder adapted to hold the implant during insertion of the implant between the vertebral bodies;
- a refractor adapted to retract the holder away from the implant after the insertion;
- and
- a guard adapted to prevent the implant front being removed from between the vertebral bodies during the retraction;
- wherein:
- the guard comprises a shaft having a proximal end and a distal end;
- the holder comprises a plurality of arms, each having a distal end, the arms being adapted to cooperate to hold the implant using the distal ends of the arms such that the implant is adjacent the distal end of the shaft;
- the retractor comprises a bore and a screw that can thread within the bore and engage the proximal end of the shaft.

An instrument for inserting an implant between vertebral bodies, comprising:
- a holder adapted to hold the implant during insertion of the implant between the vertebral bodies;
- a retractor adapted to retract the holder away from the implant after the insertion;
- and
- a guard adapted to prevent the implant from being removed from between the vertebral bodies during the retraction;
- wherein the guard comprises a shaft having a longitudinal axis, a proximal end having an engagement surface, and a distal end;
- and
- wherein the holder comprises a plurality of arms, each having a proximal end and a distal end and each longitudinally extending alongside the shaft, the arms being adapted to cooperate to hold the implant using the distal ends of the arms such that the implant is longitudinally adjacent the distal end of the shaft during insertion of the implant between the vertebral bodies;
- and
- wherein the retractor comprises a bore in longitudinally fixed relation to the arms during the retraction and having a longitudinal axis coaxial with the longitudinal axis of the shaft during the retraction, and a screw that can thread within the bore and having a distal end that can engage the engagement surface of the proximal end of the shaft during the retraction.

An instrument for inserting art implant between vertebral bodies, comprising:
- a holder adapted to bold the implant during insertion of the implant between the vertebral bodies;
- and
- a refractor adapted to retract the bolder away from the implant after the insertion;
- wherein the refractor comprises a coupling by which relative movement between the holder and the refractor is effectable during the retraction.
1 more element
An instrument for inserting an implant between vertebral bodies, comprising:
- a set of tongs having a proximal end and distal ends adapted to hold the implant during the insertion of the implant between the vertebral bodies;
- and
- a central rod about which the set of tongs can open and close, having a proximal end and a distal end in front of which the distal ends of the set of tongs can hold the implant during the insertion, the rod being coupled to the set of tongs to prevent lateral movement between the rod and the set and allow longitudinal movement between the rod and the set;
- wherein the rod is coupled to the set of tongs by a coupling comprising a lateral through slot through the rod that extends longitudinally within the rod, and a pin on the set of tongs that passes laterally through the through slot.
