Abstract: An orthopedic broach is disclosed. The orthopedic broach includes a cutting tip and a broach handle. The broach handle includes a lever, a spring, and a latch. The lever is movably coupled to the handle and to an end of the spring. The latch is movably coupled to the handle and the opposite end of the spring. In use, the lever is movable from an opened position, where the latch is positioned in a released position, so that the cutting tip can be inserted into the handle, to a closed position where the latch is moved to an engaged position wherein the cutting tip is securely coupled to the latch, and thus the handle. The handle includes a spring stop to prevent the spring from further deflection to prevent the latch from moving to the released position and thus prevent decoupling of the cutting tip when excessive forces are applied.

Abstract: A computer-implemented method for determining implant positions of two implant components relative to two bones that form a joint is disclosed. The method includes acquiring a set of target poses to be achieved between the two bones, assessing one or more proposed implant arrangements using the set of target poses, and selecting an implant arrangement from the proposed implant arrangements based on the assessment. Assessing an implant arrangement includes determining a real pose between the two bones for each target pose, calculating a pose deviation value for each target pose based on the target pose and the corresponding real pose, and calculating an overall pose deviation value from the individual pose deviation values. The implant arrangement may be selected based on the overall pose deviation values for the proposed implant arrangements.

Abstract: A surgical tool positioning device for positioning and holding a surgical tool is disclosed. The device includes an adjustable-friction ball and socket joint configured to provide three degrees of rotational freedom. A variable holding force may be applied to the ball via a locking member to selectively lock and unlock the adjustable-friction ball and socket joint. The socket includes a friction-inducing member housed therein and in contact with the ball. When the ball and socket joint is unlocked, this friction-inducing member provides sufficient frictional force to hold a position of the surgical tool. However, this frictional force may be overcome with intentional external forces such as during repositioning of the surgical tool.

Abstract: A method of calibrating a frontal 2D image of a pelvis of a patient is disclosed. Frontal and lateral 2D images are received, where a fiducial marker is positioned on the patient's suprapubic region during image capture. A first distance of the fiducial marker from the imaging detector is determined based on the fiducial marker's measured diameter in the frontal image. A second distance of the fiducial marker from a coronal plane of the pelvis is determined based on the fiducial marker's measured diameter in the lateral image. The second distance is corrected based on a rotational offset of the patient in the lateral image. A third distance of the coronal plane from the imaging detector in the frontal image is determined from the first distance and corrected second distance. A calibration factor for the frontal image is calculated from the third distance and used to scale the frontal image.
