    摘要: Systems, methods and processes for computer-assisted soft tissue balancing, including ligament balancing, determining surgical cuts, and positioning or placement of the components of the prosthetic knee during TKR. The improved methods, systems and processes resolve several problems related to the prosthetic knee component positioning and soft-tissue balancing during computer-assisted TKR. The improved methods, systems and processes are flexible and versatile, provide reliable recommendations to the surgeon, and improve restoration of the knee function and patient recovery.

    摘要: A probe for data input for a computer-assisted surgical system, comprising a body; one or more movable fiducials operably associated with the probe; and one or more stationary fiducials operably associated with the probe; wherein the movement of the one or more movable fiducials relative to the one or more of the stationary fiducials triggers data input on a position or an orientation of the probe, or both. The probe is particularly suitable for minimally invasive surgery. Also provided is a method of using the probe to input data during computer-assisted surgery.

    摘要: A pedicle access system including a cannula, a stylet, and a removable T-handle. The pedicle access system may be used to percutaneously approach the pedicle, initiate pilot hole formation, and conduct a stimulation signal to the target site for the purposes of performing a pedicle integrity assessment during the pilot hole formation. To do this, the cannula and stylet are locked in combination and inserted through an operating corridor to the pedicle target site, using the T-handle to facilitate easy movement and positioning of the cannula/stylet combination. A stimulation signal may be applied during pilot hole formation to conduct the pedicle integrity assessment. In a significant aspect, the T-handle may be detached from the cannula/stylet combination to facilitate the use of various surgical tools as necessary.

    摘要: Systems and methods for performing minimally invasive incisions may provide guidance for performing a surgical incision by tracking and comparing the position, in real time, of an incision device with a suggested incision path and length. A computer aided surgical navigation system may track the incision device and calculate the suggested incision path and length by tracking the positions and/or orientations of surgical references exhibiting fiducial functionality associated with the incision device and the individual to be incised.
