Apparatus and methods for inserting an implant

摘要

A system and method for inserting an implant into a cavity is disclosed, which may include advancing an implant insertion instrument toward a pair of adjacent bodies, the implant insertion instrument having two opposed ramps, wherein each ramp has a distal tip and wherein the longitudinal axes of the opposed ramps are separated by an initial angle; inserting the distal tips of the opposed ramps between the adjacent bodies, thereby creating an initial interbody cavity between the adjacent bodies; expanding the interbody cavity while maintaining the initial angle between the longitudinal axes of the opposed ramps; placing the implant in a final location between the adjacent bodies; transferring a compressive force urging the adjacent bodies together from the opposed ramps to the implant; and extracting the implant insertion instrument from the interbody cavity.

主权项

1. A surgical system comprising:
an implant having opposing sidewalls and a proximal wall, at least one of the walls having a tool engaging feature; and an insertion tool including:
a handle,a rod having a first end coupled to the handle and a second end releasably attachable to the implant, the implant configured to cooperate with longitudinal advancement and retraction of the rod when attached to the rod,an elongate member having a lumen extending therethrough such that the rod is longitudinally translatable in the lumen,opposing first and second jaws defining an angle, the first and second jaws disposed in a distal region of the elongate member, the implant located between the jaws and longitudinally movable relative to the jaws such that a distance between the jaws increases as the implant is moved distally, and a first mechanism engaging the first and second jaws, the first mechanism configured to maintain the angle between the first and second laws.
