Abstract: A computer-assisted surgery system comprises a first surgical device with a tracking unit tracked during a surgical procedure and adapted to perform a first function associated to the surgical procedure. A second surgical device is adapted to perform a second function associated to the surgical procedure. A triggered unit is triggered when the first surgical device and the second surgical device reach a predetermined proximity relation. A surgical procedure processing unit tracks the first surgical device. A trigger detector detects a triggering of the triggered unit. A CAS application operates steps of a surgical procedure. A controller commands the CAS application to activate a selected step associated with the second function in the surgical procedure when the trigger detector signals a detection. An interface displays information about the selected step in the surgical procedure.

Abstract: A method for assisting in positioning the acetabular cup comprises orienting a cup positioning instrument with a cup thereon in an initial reference orientation relative to an acetabulum of a pelvis with the cup forming a joint with the acetabulum, the cup positioning instrument comprising an inertial sensor unit with pre-planned orientation data for a desired cup orientation based on at least one landmark of the pelvis, The cup positioning instrument is rotated to a desired abduction angle as guided by an interface of the cup positioning instrument, based on movements relative to at least one landmark. The cup positioning instrument is rotated to a desired anteversion angle as guided by the interface of the cup positioning instrument, based on movements relative to the at least one landmark. Upon reaching the desired cup orientation as indicated by the interface, the cup is impacted into the acetabulum.

Abstract: A computer-assisted surgery (CAS) system comprises a cup implanting device including a shaft having a tooling end and a handle end with a handle for being manipulated, the shaft having a longitudinal axis, the tooling end adapted to support a cup for being received in an acetabulum of a patient, and a rotation indicator having a visual guide representative of a device plane, wherein the device plane is in a known position and orientation relative to a center of the cup on the tooling end. A CAS processing unit includes at least one inertial sensor unit connected to the cup implanting device, the inertial sensor unit outputting three-axes readings and having a virtual preset orientation related to a reference axis of a pelvis of the patient, the virtual preset orientation being based on pre-operative imaging specific to the pelvis of the patient, the reference axis of the pelvis passing through a center of rotation of said acetabulum of the pelvis and through a reference landmark of the pelvis, wherein an instant three-axis orientation of the longitudinal axis of the cup implanting device is trigonometrically known relatively to the reference axis when the cup is in the acetabulum of the patient and the device plane passes through the reference landmark via the visual guide, the instant three-axis orientation used for calibrating the inertial sensor unit on the cup implanting device relative to the pelvis.

Abstract: A system for determining a position and an orientation of a bone of an anatomical feature includes a trackable reference device having a surgical pin at a first position being attachable to the bone. A wearable attachment attached to the trackable reference device is configured to be mounted about the outer-skin surface of the anatomical feature. A distance sensor mounted to the trackable reference device at a second position is operable to determine a distance measurement of the second position of the trackable reference device from the bone. Reference markers are fixedly mounted to the trackable reference device. A position sensing device registers position and orientation readings of the reference markers in a reference coordinate system. A processing unit determines the position and the orientation of the bone in the reference coordinate system using the position and orientation readings and the distance measurement.

Abstract: A computer-assisted surgery (CAS) system for tracking an orientation of a pelvis comprises at least one instrument, the instrument having an acetabulum abutment end adapted to be received in an acetabulum, a rim abutment adapted to be abutted against a rim of the acetabulum, and an indicator representative of a physical orientation of the instrument. An inertial sensor unit is connected to the at least one instrument, the inertial sensor unit producing readings representative of its orientation. A computer-assisted surgery processor unit comprises a coordinate system module for setting a pelvic coordinate system from readings of the at least one inertial sensor unit when the at least one instrument has the acetabulum abutment end received in the acetabulum, the coordinate system module setting the pelvic coordinate system by obtaining a plurality of orientation values from the at least one inertial sensor unit when the rim abutment is abutted against locations of the rim, one of said orientation values having the indicator aligned with a reference landmark, the coordinate system module defining an acetabular plane representative of the pelvic coordinate system from the plurality of orientation values; and a tracking module for tracking an orientation of the at least one inertial sensor unit relative to the pelvic coordinate system during movements thereof using the readings from the inertial sensor unit. An interface outputs orientation data as a function of the pelvic coordinate system.

Abstract: Systems and methods for determining position and orientation of a bone of an anatomical feature are described. These include the use of a wearable holder configured to be mounted about an outer-skin surface of the anatomical feature, such that the anatomical feature and the bone are positioned in fixed relation with respect to the wearable holder when the wearable holder is mounted about the anatomical feature. Reference marker arrays are fixedly mounted to the wearable holder, each being positioned on the wearable holder to identify a landmark of the bone within the wearable holder when the wearable holder is mounted to the anatomical feature. The position and orientation of the reference markers are trackable to determine position and orientation of the wearable holder in a reference coordinate system, thereby enabling position and orientation of the landmarks on the bone to be determined.
