The overvoltage protection circuit includes a regulation device connected between the input and output terminals. The regulation device provides the output voltage using the input voltage and the regulation signal. The overvoltage protection circuit includes a modification device to modify a value of the divided voltage using the test voltage.

Abstract: A method for robotic assisted surgery. The method includes capturing a plurality of poses of a surgical tool coupled to a robotic device at a surgical site. The plurality of poses correspond to instances of a final placement of surgical implants at the surgical site. The method also includes determining a plurality of positions of the surgical implants located at the surgical site based on the captured plurality of poses. The method also includes generating a bend curve having a plurality of bend points based on the determined plurality of positions of the surgical implants. The method also includes generating bending instructions for bends to be performed on a linking device configured for attachment to the surgical implants.

Abstract: The present invention relates to a system and methods generally aimed at surgery. More particularly, the present invention is directed at a system and related methods for performing surgical procedures and assessments involving the use of neurophysiology.

Abstract: Methods are provided for planning, performing, and assessing of surgical correction to the spine during a spinal surgical procedure. These methods are implemented by a control unit through a GUI to digitize screw locations, digitize anatomical reference points, accept one or more correction inputs, and generate one or more rod solution outputs shaped to engage the screws at locations distinct from the originally digitized locations.

Abstract: A system for use during a surgical procedure includes a control unit configured to obtain a first anatomical characteristic of a patient; measure a second anatomical characteristic of a patient; create a targeted second anatomical characteristic; and convert at least one of the measured second anatomical characteristic and the targeted second anatomical characteristics to a patient position.

Abstract: A digitizer pointer is provided as part of a system for correcting a curvature or deformity in a patient's spine based on the digitized locations of implanted screws and tracking the placement of the rod as it is placed in a minimally invasive fashion. The digitizer pointer includes an offset adjustment feature, a swivel feature, and a translation feature.

Abstract: 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.

Abstract: The present application describes computer apparatus and software programs useful to the field of corrective spinal surgery. The apparatus and software implement and facilitate methods for assessing the degree of balance and alignment achieved through corrective measures applied to the spine prior to completing a surgical procedure. The apparatus and software facilitate pre-operative planning and virtual testing of the corrective measures to be applied. The apparatus and software further facilitate intra-operative reconciliation with the pre-operative plan prior to completing the surgery.

Abstract: A delivery device for the fuel of an internal combustion engine has a fuel tank (4) from which at least one fuel pump (14, 18) delivers fuel via a fuel supply line (10) and via at least one fuel filter (12, 16) to a fuel consumer (2). The consumer (2) is connected to the fuel tank (4) via a fuel return line (20). A control device (24) is connected between the supply line (10) and the return line (20). The control device establishes a fuel-conveying connection (80) between the return line (20) and the supply line (10) when the temperature in the fuel tank (4) falls below a predeterminable threshold temperature and at a predeterminable threshold pressure in the return line (20).
