Abstract
A system for tibial bone resection, comprising a device including a handle and a rasp coupled to the handle. The rasp includes a top surface, a bottom surface, a first side surface, and a second side surface. A portion of the top surface includes a first rough surface, a portion of the first side surface includes a second rough surface, and a portion of the second side surface includes a third rough surface. A first smooth curved surface separates the first rough surface from the second rough surface, and a second smooth curved surface separates the first rough surface from the third rough surface.
Claims43
A device comprising:
- a handle;
- and
- a rasp coupled to the handle, wherein the rasp includes a top surface, a bottom surface, a first side surface, and a second side surface, wherein a portion of the top surface includes a first rough surface, wherein a portion of the first side surface includes a second rough surface, wherein a portion of the second side surface includes a third rough surface, wherein a first smooth curved surface separates the first rough surface from the second rough surface, and wherein a second smooth curved surface separates the first rough surface from the third rough surface.
A system comprising:
- a first bushing configured to be removably coupled to a tibia of a patient, wherein the first bushing includes a first plurality of through-holes;
- and
- a second bushing configured to be removably coupled to the tibia of the patient wherein the second bushing includes a second plurality of through-holes.
A system comprising:
- a first bushing configured to be removably coupled to a tibia of a patient, wherein a first bushing includes a first plurality of through-holes;
- a patient specific disposable surface that is configured to be removably coupled to a first side of the first bushing;
- and
- a patient specific depth guide that is configured to be removably coupled to a second side of the first bushing, wherein the patient specific depth guide includes a plurality of through-holes that align with the first plurality of through-holes of the first bushing.
A method comprising:
- removably coupling a first bushing to a tibia of a patient, wherein the first bushing includes a first plurality of through-holes;
- plunging a reamer through the first plurality of through-holes and into the tibia;
- removably coupling a second bushing to the tibia of the patient, wherein the second bushing includes a second plurality of through-holes;
- and
- plunging the reamer through the second plurality of through-holes and into the tibia.
A method comprising:
- removably coupling a first bushing to a tibia of a patient, wherein the first bushing includes a first plurality of through-holes;
- removably coupling a patient specific disposable surface to a first side of the first bushing;
- removably coupling a patient specific depth guide to a second side of the first bushing, wherein the patient specific depth guide includes a plurality of through-holes that align with the first plurality of through-holes of the first bushing;
- and
- plunging a reamer through the first plurality of through-holes, through the patient specific disposable surface, and into the tibia of the patient.
