Bone positioning device and method

摘要

A method for positioning a bone cut on a bone may involve: coupling a bone cut positioning apparatus with a body bone; adjusting the positioning apparatus in a varus/valgus orientation relative to the body bone; adjusting the positioning apparatus in an anterior/posterior orientation relative to the body bone; and adjusting the positioning apparatus up or down to select a bone resection level.

1. A method for positioning a bone cut on a tibia, the method comprising:
coupling a bone cut positioning apparatus to a tibia, the positioning apparatus including a bone cutting guide; attaching a laser light emitter to a swing arm of the positioning apparatus, the attaching including activating the laser light emitter such that it can emit laser light; positioning the swing arm and the laser light emitter into a first orientation relative to the tibia; adjusting, with the swing arm and the laser light emitter in the first orientation, the positioning apparatus in a varus/valgus orientation relative to the tibia, including using emitted laser light from the laser light emitter to position the bone cutting guide in reference to an anterior surface of the tibia; positioning, by pivoting, the swing arm and the laser light emitter into a second orientation such that the laser light emitter can emit laser light to provide orientation along a medial or a lateral surface of the tibia; adjusting, with the laser light emitter in the second orientation, the positioning apparatus in an anterior/posterior orientation relative to the tibia, including using emitted laser light from the laser light emitter to position the bone cutting guide in reference to the medial or the lateral surface of the tibia; and adjusting the positioning apparatus up or down to select a tibial bone resection level wherein at least one of the adjusting the positioning apparatus operations includes adjusting a screw coupled with a captured ball to move a portion of the positioning apparatus about a pivot, the screw coupled with the captured ball via a threaded shaft through the captured ball.
