Implant inserter

摘要

An apparatus for inserting an implant between vertebrae includes a body having a through bore, a central shaft movable within the through bore, the central shaft having a proximal end and a distal end. The apparatus includes a pair of distractor arms having proximal portions and distal portions, the proximal portions pivotally coupled to the body and distal portions for engagement between the vertebrae. Tracking slots are formed in and extend through surfaces of and along a longitudinal axes of the distractor arms and an attachment tip is operably connected to the central shaft, the attachment tip is configured to grip the implant. The apparatus includes a single guide member projecting outward from the attachment tip and the attachment tip is removably connectable to the central shaft in multiple configurations.

1. A method for inserting an implant between vertebrae, comprising the steps of:
accessing an area between vertebrae; providing an instrument comprising:
a body having a through bore;a tubular portion received in the body, wherein the tubular portion comprises at least one window;a central shaft movable within the through bore, the central shaft having a proximal end and a distal end;a pair of distractor arms having proximal portions and distal portions, the proximal portions pivotally coupled to the body and distal portions for engagement between the vertebrae;tracking slots formed in and extending through surfaces of and along a longitudinal axes of the distractor arms;an attachment tip operably connected to the central shaft, the attachment tip configured to grip the implant;a rotatable dial configured to control engagement and disengagement of the implant to the attachment tip; anda single guide member projecting outward from the attachment tip, wherein the attachment tip is removably connectable to the central shaft in multiple configurations; positioning the instrument to distract the adjacent vertebrae; positioning an implant between the adjacent vertebrae; and releasing the implant from the instrument.
