Abstract: A method for registering one or more surfaces associated with a bone for implant revision procedures includes a digitizer used to digitize surface points on remaining cement, bone surfaces, or both. The bone is adapted to hold a primary implant and from which the primary implant was removed. The position of the one or more surfaces associated with bone is registered by computing at least one of: a generic set of one or more planes using the surface points or a best match between a known implant geometry and the surface points. A computer-assisted surgical system is also provided to execute the method.

Abstract: A protective drape for a robotic arm is provided. The protective drape may be used with robotic arm that are required to operate in varied environments that illustratively include industrial applications, a sterile surgical suite for patient care, and a clean room for manufacturing sensitive electronic components. In each of these applications, there is a need to prevent contaminants from infiltrating from the environment to the robot and affecting operation of the robot itself or the robotic system, as well to prevent contaminants from the robot from infecting a patient or contaminating an assembly or process product.

Abstract: A method for removing an implant attached to a bone during revision joint replacement surgery includes a library of implant models. A series of surface points are collected on the implant with a digitizer. A best match is computed between the collected surface points and an implant model in the library of implant models to register the position of the implant model to the implant. A location is computed of a material-implant interface based on the geometry of the implant model and the registered position of the implant model. Material is removed at the material-implant interface to separate the implant from the bone. A computer-assisted surgical system is provided for performing the method.

Abstract: A system and process for performing orthopedic surgery is provided that uses a patient's existing implant as a registration tool in an orthopedic surgical procedure. The systems and processes may be used with computer assisted systems or navigation systems to aid in the removal of bone, bone cement, or a bone prosthesis, typically a bone prosthesis used in hip replacement surgery, knee replacement surgery, and the like. The removal of the prosthesis may be done by conventional methods, with navigation systems, robotic assistance or articulating hand held systems. The removal of bone and/or bone cement may be performed with navigated systems, robotic systems, articulating hand-held systems and combinations thereof.

Abstract: A modular wrist guide is provided that aids a user in operating a hand-held surgical instrument to accurately perform surgical procedures including but not limited to joint arthroplasty. The modular wrist guide acts to constrain the orientation of a hand-held surgical instrument, or a user's wrist relative to the user's forearm to perform a procedure according to a surgical plan. A forearm embracing member is designed to secure the user's forearm to the modular wrist guide.
