SYSTEMS FOR AND METHODS OF PREPARING A SACROILIAC JOINT FOR FUSION

摘要

A surgical preparation tool for preparing a sacroiliac joint for a surgical procedure comprising a trial tool assembly and a cutting tool configured to releasably and slidably couple with the trial tool assembly, wherein the trial tool assembly is configured to guide the cutting tool during distal-proximal translation such that as the cutting tool distally advances relative to an implant trial of the trial tool assembly, at least a portion of a cutting element of the cutting tool extends generally over and perpendicularly outward from a first top surface of a body of the implant trial.

主权项

1. A surgical preparation tool for preparing a sacroiliac joint having a sacrum and an ilium for a surgical procedure, the tool comprising:
a) a trial tool assembly comprising an implant trial at a distal end of the trial tool assembly and a trial shaft coupled to and extending proximally from the implant trial, the implant trial comprising a body comprising a first length extending along a longitudinal axis from a proximal to a distal end, a first top surface, a first bottom surface generally opposite the first top surface, and a thickness defined between the first top and first bottom surfaces, the implant trial configured to be delivered non-transversely into the sacroiliac joint such that the first top and first bottom surfaces oppose either the sacrum or the ilium; and b) a cutting tool configured to releasably and slidably couple with the trial tool assembly, the cutting tool comprising a cutting element at a distal end of the cutting tool and a cutting shaft extending proximally from the cutting element, the cutting element comprising a second length extending from a proximal to a distal end; wherein the trial tool assembly is configured to guide the cutting tool during distal-proximal translation such that as the cutting element distally advances relative to the implant trial, at least a portion of the cutting element extends generally over and perpendicularly outward from the first top surface of the body of the implant trial.
