Robotic arthroplasty system

摘要

Embodiments include a robotic mechanism that may be utilized to position prosthetic implants in a patient's body. During joint replacement surgery and other surgical procedures, prosthetic implants may be placed in a patient's body. The robotic mechanism may be utilized to control movement of a cutting tool during resection of bone in a patient's body. The robotic mechanism includes a programmable computer which is connected with the force transmitting member by a motor. A force measurement assembly is connected with the force transmitting member and the computer. The output from the force measurement assembly is indicative of a resistance encountered by the force transmitting member. A position sensor is connected with the force transmitting member and the computer. The position sensor has an output indicative of the position of the force transmitting member.

主权项

1. A robotic surgical system comprising:
a robotic mechanism having a force transmitting member, wherein the robotic mechanism is configured to perform a surgical procedure without being coupled to an operating table; a computer connected with the robotic mechanism; a navigation system comprising:
an optical sensing system connected with the computer; andat least one navigation member positionable through the skin of a patient into one or more tissues of the patient, wherein at least one navigation member has a reflective end visible to the optical sensing system,wherein the optical system is configured to determine location information of a bone relative to tissue based on the at least one navigation member, andwherein the optical system is configured to provide the determined location information of the bone to the computer for use by the robotic mechanism; and a tool configured to resect at least a portion of a joint surface of a bone in the patient, wherein the robotic mechanism is configured to control movement of the tool during resection of the joint surface in preparation for receipt of an arthroplasty component, wherein the force transmitting member of the robotic mechanism is configured to position the arthroplasty component in the body of the patient, to cover at least a portion of the resected joint surface.
