Sacroiliac fusion system

摘要

An undercutting system for preparing a region between an ilium and a sacrum for sacroiliac fusion. The undercutting system includes an insertion apparatus, a probe assembly and a cutting assembly. The probe assembly is operably mounted to the insertion apparatus. The probe assembly is moveable with respect to the insertion apparatus between a retracted configuration and an extended configuration. In the extended configuration at least a portion of the probe assembly extends from the insertion apparatus. The cutting assembly is operably mounted with respect to the probe assembly and the insertion apparatus. The cutting assembly is movable with respect to the insertion apparatus between a retracted configuration and an extended configuration. In the extended configuration at least a portion of the cutting assembly extends from the insertion apparatus.

1. An undercutting system for preparing a region between an ilium and a sacrum for sacroiliac fusion, wherein the undercutting system comprises:
an insertion apparatus; a probe assembly that is moveable with respect to the insertion apparatus between a retracted configuration and an extended configuration, wherein in the extended configuration at least a portion of the probe assembly extends from the insertion apparatus; and a cutting assembly that is movable with respect to the insertion apparatus between a retracted configuration and an extended configuration, wherein in the extended configuration at least a portion of the cutting assembly extends from the insertion apparatus, wherein the cutting assembly extends over at least a portion of the probe assembly, wherein the cutting assembly is sharper than the probe assembly and wherein the cutting assembly has a plurality of kerfs formed therein.
