Methods and systems for robotic-assisted surgery using customized bone registration guides

A method for performing an arthroplasty procedure, the method comprising:

• receiving a plurality of two-dimensional images of a patient's joint the subject of the joint arthroplasty procedure;
• generating, based on locating a plurality of mating shapes within the plurality of two-dimensional images of the patient's joint, a customized registration guide for the patient's joint for use during the joint arthroplasty procedure and comprising one or more drill bit guides;
• and
• mounting, using the customized registration guide and a plurality of registration pins based on the one or more drill bit guides of the customized registration guide, a robotic device on the patient's anatomy, the robotic device comprising:
• a controller base unit configured to activate a first link joint of the controller base and a second link joint of the controller base, the second link joint distinct from the first link joint;
• a mounting device mechanically coupled with the first link joint of the controller base unit via a plurality of configurable links comprising at least a translation link configured to translate with two degrees of freedom transversal to each other to orient the controller base unit in relation to the mounting device and corresponding to the joint arthroplasty procedure;
• and
• a configurable resection guide mechanically coupled with the second link joint of the controller base unit and oriented to provide a resection guide for the joint arthroplasty procedure;
• wherein the first link joint provides one degree of rotational freedom between the mounting device and the controller base unit and the second link joint provides one degree of rotational freedom between the resection guide and the controller base unit.
