Multi-purpose robotic operating system and method

A dynamically configurable robotic system and method for performing surgical operations using a plurality of robotic arms remotely controlled by at least one operator console. The system comprises a track system configured for mounting to a patient support table, such that the track system provides a stable operating platform for the robotic arms and for facilitating placement of a proximal end of each of the arms at a selected position about a periphery of the patient support table. the system and method also have a plurality of base stations for operatively coupling each of the robotic arms to the track system, such that each of the base stations include a housing, a first connector for coupling the housing to the track system, the first connector configured for facilitating movement of the housing along the track system while coupled thereto, and a second connector for coupling the housing to the proximal end of at least one of the robotic arms, the second connector configured for providing at least one of power supply, control signalling, and data communication with respect to the coupled robotic arm. The system and method also have a control unit for coupling to at least two of the base stations and configured for dynamically connecting operative remote control between the coupled base stations and a first operator console of the at least one operator console.

Method and apparatus for positioning a bone prosthesis using a localization system

Methods and apparatus using a surgical navigation system to position the femoral component of a prosthetic hip during hip joint replacement surgery without separately affixing a marker to the femur. The navigation system acquires the center of rotation of the hip joint as well as at least one point on the femur in the pelvic frame of reference. From these two points, the navigation system calculates the position and length of a first line between the center of rotation of the hip joint and the point on the femur. Optionally, a second point on the femur that is not on the first line is palpated. The system can calculate the position and length of a second line that is perpendicular to the first line and that runs from the first line to the second palpated point on the femur. The prosthetic cup is implanted and its center of rotation is recorded. A tool for forming the bore within which the stem of the femoral implant component will be placed is tracked by the navigation system. While the tool is fixed to the femur, the surgeon re-palpates the same point(s) on the femur that were previously palpated. The navigation system calculates the position and length of a first line between the center of rotation of the prosthetic cup and the re-palpated first point. If a second point on the femur was re-palpated, the navigation system also calculates the position and length of a perpendicular line between the first line and the second point. The surgical navigation system uses this information to calculate and display to the surgeon relevant information about the surgery, such as change in the patient's leg length and/or medialization/lateralization of the joint.
