US Patent 9808318 Robotic arthroplasty system

A robotic system for use in performing an arthroplasty procedure of a patient is provided. The robotic system includes a robotic mechanism, a cutting tool coupled to the robotic mechanism for resecting a portion of a bone of the patient through an incision in the skin of the patient, and a computer coupled to the robotic mechanism and configured to control the robotic mechanism. The robotic system also includes at least one navigation member positionable into engagement with tissue in the patient, an optical system coupled to the computer, a position sensor configured to provide movement information of the robotic mechanism relative to the bone, and an interface coupled to the computer, the interface configured to operate the computer.
