US 2026/0294448 A1 · SYSTEM AND METHOD FOR ALIGNING A CUT GUIDE ON A BONE

Abstract

A guide is provided that includes a first guide tube having a first bore sized to accommodate a first bone pin and a bone contacting surface configured to contact a bone surface. A second guide tube having a second bore sized to accommodate a second bone pin or a surgical boring tool is also provided. A cross-bar portion interconnects the first guide tube and the second guide tube and is configured to space the first bore a pre-determined distance from the second bore. A process for aligning a cut guide on a bone at a pre-determined location using the guide is also provided. A system is also provided that includes the guide, a robotic device, and a computing system operative for forming holes in the bone for receiving a portion of a cut guide therein for aligning the cut guide on the bone at a pre-determined location.

A system, comprising:

the guide of claim l;
a robotic device configured to removably couple to a first tool and a second tool and control movement of the first tool and the second tool;
and
a computing system comprising one or more processors configured to:
generate first control signals for the robotic device to maintain alignment of an axis of a first tool, when coupled to the robotic device, coincident with a virtual plane having a pre-defined location with respect to the bone for inserting the first pin in the bone coincident with the virtual plane;
and generate second control signals for the robotic device to maintain alignment of an axis of a second tool, when coupled to the robotic device, coincident with the virtual plane for inserting the second pin in the bone coincident with the virtual plane, wherein the alignment of the axis of the second tool is maintained with the virtual plane while at least a portion of the first tool inserted in the bone is positioned inside the first bore and at least a portion of the second tool is positioned inside the second bore for inserting the second tool in the bone at a pre-defined distance from the first tool inserted in the bone, and wherein the first tool and the second tool inserted in the bone each form a hole in the bone for receiving a portion of a cut guide therein for aligning the cut guide on the bone at a pre-determined location.
