A computer-implemented method to improve the point collection process during registration of a bone for a computer-assisted surgical procedure is provided. Based on bone digitization data, a simulation is performed to confirm the accuracy of the registration for different digitization regions. Results are tested to identify which digitization regions meet a predefined accuracy requirement. The resulting information is used to perform a computer-assisted surgical procedure. A computerized simulation method for registration of a bone for a computer-assisted surgical procedure is also provided based on processor executing random stroking an expected exposed surface of a bone model with multiple of stroke curves to cover most of the bone model surface with uniform noise and a random sample consensus is applied to remove outlying point to yield the best registration results, to find the top subset as to overlap. A method to perform computer-assisted surgery is also provided.

Bone registration methods for robotic surgical procedures

A system and process is provided for dynamically positioning or repositioning a robot in a surgical context based on workspace and task requirements, manipulator requirements, or user preferences to execute a surgical plan. The system and method accurately determines and indicates an optimal position for a robot with respect to a patient's anatomy before or during a surgical procedure. Optimal positions for a robot are intuitively indicated to a user. surgical procedures can illustratively include surgery to the knee joint, hip joint, spine, shoulder joint, elbow joint, ankle joint, jaw, a tumor site, joints of the hand or foot, and other appropriate surgical sites.

Method and system for guiding user positioning of a robot

A system and method of use thereof are provided for dynamically generating an environmental map for use in robotic assisted surgery. The generated environmental map is used to plan a recovery tool path that an end-effector tool can safely and efficiently follow to re-position the tool back to a cutting position following the displacement of the tool from the cutting position. Additionally, the environmental map is used to update a virtual representation of a bone to provide a user with visual feedback as to the progression of the end-effector tool as the tool removes material from the bone during a surgical procedure.
