摘要： A CAS system and method for guiding an operator in inserting a femoral implant in a femur as a function of a limb length and orientation of the femoral implant with respect to the femur, comprising a reference tool for the femur, a registration tool, a bone altering tool and a sensing apparatus. A controller is connected to the sensing apparatus to: i) register a frame of reference of the femur by calculating surface information provided by the registration tool as a function of the position and orientation of the registration tool provided by the sensing apparatus, and/or retrieving in a database a model of the femur; ii) calculate a desired implant position with respect to the frame of reference as a function of the limb length; and iii) calculate a current implant position and orientation in relation to the desired implant position with respect to alterations being performed in the femur with the bone altering tool, as a function of the position and orientation of the bone altering tool provided by the sensing apparatus and of a digital model of a femoral implant provided by the database. The database is connected to the controller for the controller to store and retrieve information relating to an operation of the controller. The computer-assisted system may be used to guide an operator in inserting a pelvic implant in an acetabulum as a function of an orientation of the pelvic implant with respect to the pelvis.

摘要： A surgical system for positioning a prosthetic component on an anatomy of a patient includes a surgical tool configured to engage the prosthetic component, a force system configured to provide at least some force to the surgical tool, and a controller programmed to compare a target pose of the prosthetic component and an actual pose of the prosthetic component engaged by the surgical tool and generate control signals that cause the force system to allow movement of the surgical tool within a range of movement and provide haptic feedback to constrain a user's ability to manually move the surgical tool beyond the range of movement. The haptic feedback resists movement of the surgical tool by the user that would cause substantial deviation between at least one aspect of the actual pose of the prosthetic component and a corresponding aspect of the target pose of the prosthetic component. The controller is programmed to generate control signals that cause the force system to maintain the haptic feedback as the user implants the prosthetic component on the anatomy.

摘要： A haptic robotic system for reaming an acetabulum prior to inserting an acetabular cup is more accurate than conventional instruments and may reduce the risk of dislocation and improve durability of a hip implant. Disclosed is a three-dimensional tool path, referred to as a haptic volume. Once the haptic volume is implemented into the software of a haptically constrained surgical robotic system, the cutting tool or reamer can only be utilized within the haptic volume. The haptic volume guides the surgeon in preparing the final reamed bone surface with a greatly reduced chance of the reaming unintended bone and greatly increases the chance that the reaming procedure may be carried out using one reaming tool, or using a single-stage reaming process.

摘要： A CAS system (50) and method (100) for measuring surgical parameters during hip replacement surgery to guide an operator (S) in inserting a hip joint implant in a femur, comprising a first trackable reference (56) in fixed relation with the pelvis and a registration tool (56). A sensor apparatus (54) tracks the first trackable reference (56) and the registration tool (56). A controller unit (52) is connected to the sensor apparatus (54) so as to receive tracking data for the first trackable reference (56) and the registration tool (56). The controller unit (52) has a position and orientation calculator (202) to calculate from the tracking data a position and orientation of the pelvic trackable reference (56) to track the pelvic frame of reference, and of the registration tool (56) to produce a femoral frame of reference at two sequential operative steps. A reference orientation adjustor (204) receives tracking data for the pelvic frame of reference, and the femoral frame of reference associated with the first trackable reference (56), to orient the femoral frame of reference in a reference orientation with respect to the pelvic frame of reference, and to produce a reference adjustment value as a function of the reference orientation. A surgical parameter calculator (206) receives tracking data from the registration tool (56) to calculate surgical parameters as a function of the reference adjustment value, the surgical parameters at the two sequential operative steps being related by the reference orientation.

摘要： A surgical bone reference assembly for communication with a CAS system, comprises a bone anchor fastenable to a bone element, an adjustable support and a trackable member that is located and tracked in three dimensional space by the CAS system. The support is removably fastenable to the bone anchor member and permits variable positioning relative to the bone anchor member. The support is intra-operatively detachable from and re-fastenable to the bone anchor member. A method of using a CT-free CAS system for determining a change in position of an un-tracked target limb is also provided. The method comprises engaging a trackable bone reference member to another bone element, locating and digitizing a landmark on the target limb, digitizing the landmark again following joint reduction, and determining at least one of a post-joint reduction limb length discrepancy and a target limb medio-lateral offset.

The device (10,10',20,20') comprises a detectable member (12,22) trackable for position and orientation by a computer-assisted surgery system (30). A body (11,21) is connected to the detectable member (12,22) in a known geometry. The body (11,21) has a coupling portion (14,14',24,25) adapted to be coupled to the hip joint implant component (A,F) in a predetermined configuration. The center of rotation of the hip joint implant component (A,F) is calculable in the predetermined configuration as a function of the known geometry and of the position and orientation of the detectable member (12,22).

摘要： A CAS system and method for guiding an operator in inserting a femoral implant in a femur as a function of a limb length and orientation of the femoral implant with respect to the femur, comprising a reference tool for the femur, a registration tool, a bone altering tool and a sensing apparatus. A controller is connected to the sensing apparatus to: i) register a frame of reference of the femur by calculating surface information provided by the registration tool as a function of the position and orientation of the registration tool provided by the sensing apparatus, and/or retrieving in a database a model of the femur; ii) calculate a desired implant position with respect to the frame of reference as a function of the limb length; and iii) calculate a current implant position and orientation in relation to the desired implant position with respect to alterations being performed in the femur with the bone altering tool, as a function of the position and orientation of the bone altering tool provided by the sensing apparatus and of a digital model of a femoral implant provided by the database. The database is connected to the controller for the controller to store and retrieve information relating to an operation of the controller. The computer-assisted system may be used to guide an operator in inserting a pelvic implant in an acetabulum as a function of an orientation of the pelvic implant with respect to the pelvis.
