Intervertebral implant with integrated fixation

摘要

A surgical instrument and method are provided for removal of a spinal implant from the intervertebral disc space. The instrument includes a carriage body for interfacing with the implant, a housing for interfacing with the vertebrae, and a handle portion having a first portion rotatably coupled with a proximal end of the housing and a second portion rotatably engageable with a proximal attachment portion of the carriage body. A central passage of the housing extends between the proximal end and a distal engagement surface of the housing. The central passage is dimensioned to mate with the carriage body. Rotation of the handle portion about an axis causes translational movement of the carriage body along the axis. A modular inserter/distractor apparatus and method and an anchor remover and method are also provided.

1. A surgical instrument for removing a spinal implant from the intervertebral disc space between two adjacent vertebrae, the instrument comprising:
a carriage body having a distal engagement surface for interfacing with the implant and a proximal attachment portion; a housing having a distal engagement surface for interfacing with a proximally facing surface of at least one of the adjacent vertebrae when removing the spinal implant, a proximal end, and a central passage extending between the proximal end and distal engagement surface, the central passage dimensioned to mate with the carriage body; and a handle portion having a first portion and a second portion, the first portion being rotatably coupled with the proximal end of the housing about one degree of rotational freedom defined by the axis, and the second portion being rotatably engageable with the proximal attachment portion of the carriage body; wherein rotation of the handle portion about an axis causes translational movement of the carriage body along the axis.
