Methods and devices for treating spinal deformities are provided. In one exemplary embodiment, a low-profile spinal anchoring device is provided for receiving a spinal fixation element, such as a tether, therethrough. The device generally includes a staple body that is adapted to seat a spinal fixation element, a fastening element for fixing the staple body to bone, and a locking assembly for coupling a spinal fixation element to the staple body. In one embodiment, the locking assembly includes a washer that is adapted to couple to the staple body such that the spinal fixation is disposed therebetween, and a locking nut that is adapted to engage the staple body to mate the washer to the staple body.

A surgical inserter includes a shaft, a lever, a bolt, and a locking mechanism. The shaft includes a shaft body and an engaging head. An end of the lever is adjacent to an inner side of the engaging head. The bolt is mounted on the end of the lever and passes through the engaging head to connect a medical device. The locking mechanism is movably disposed on the other end of the shaft body for selectively locking or releasing angular movement of the lever relative to the shaft body. When the lever is bending relative to the shaft body, the end of the lever pries the bolt, so that the medical device is driven by the bolt to abut against an outer side of the engaging head tightly.

An orthopedic implant screw driver includes drive shaft. A first gear is operably coupled to the drive shaft and in meshing engagement with a hollow gear which rotates in response to rotation of the drive shaft. The hollow gear includes a passage defining an inwardly facing screw engagement periphery configured to receive and drivingly rotate a threaded portion of the screw. A method of securing an orthopedic implant to a bone includes positioning a screw within the passage which is configured to drivingly engage a threaded portion of the screw and rotating a drive shaft in driving engagement with the gear causing the gear to engage the screw along the threaded portion of the screw and rotatably drive the screw via the threaded portion.

The present invention relates to a surgical tool system, to support prosthetic surgery for determining an optimal balance point of the ligamentous complex or ligament capsule of a joint, based on and visualized in a real-time stress-strain curve (SS curve) of the ligaments, comprising: a screwdriver suitable for determining stress and strain, comprising: two or more sensors, a motor, a coupling element, a control unit, suitable for reading out a torque exerted by the coupling element and an executed rotation angle of the coupling element measured by the sensors and forwarding them to an interface; the interface on which software runs, suitable for reading out a torque exerted by the coupling element and an executed rotation angle of the coupling element measured by the sensors, and interpreting and forwarding them to an interface suitable for visually displaying a stress value and strain value in an SS curve.

Disclosed herein is a guide device and a driver, which allows for the preparation of an anatomic cavity for screw fixation of an implant or spacer, including the guidance for hole preparation, and guidance for insertion of screws, and or anchors, while selecting the amount of rigidity, and selecting the amount of visibility.

Apparatus for positioning a fusion implant into a sacroiliac joint, the apparatus comprising: a directional cannula comprising: a main body having a distal end, a proximal end and a lumen extending between the distal end and the proximal end; two cannula prongs extending distally from the distal end of the main body; a distal cut-out formed in the distal end of the main body; and a proximal notch formed in the proximal end of the main body so as to define a first proximal end surface and a second proximal end surface, wherein the first proximal end surface is disposed distal to the second proximal end surface; and a combined implant tamp and joint locator configured to be disposed in the lumen of the directional cannula, the combined implant tamp and joint locator comprising: a tamp body having a distal end and a proximal end; two tamp prongs extending distally from the distal end of the tamp body; and a proximal stop formed at the proximal end of the tamp body so as to define a first stop surface and a second stop surface, wherein the first stop surface is disposed distal to the second stop surface.

A system for surgically repairing a rib of a patient is described. The system can include a first rib bracket, one or more fasteners, a driver and a caddy. The first rib bracket can be configured to be fixedly attached to a first side of the rib that faces a thoracic cavity of the patient. The one or more fasteners can be configured to fixedly attach the first rib bracket to the rib. The driver can have an end effector configured to drive the one or more fasteners into the rib. The caddy can be configured to retain the one or more fasteners and deliver these to a position adjacent the rib. The end effector can engage the one or more fasteners to drive the one or more fasteners from the caddy and into the rib to fixedly attach the first rib bracket to the first side of the rib.

A self-drilling bone fusion screw apparatus is disclosed which includes at least first and second sliding boxes. A first screw member having a tapered end and a threaded body is disposed within the first sliding box, and a second screw member having a tapered end and a threaded body disposed within the second sliding box. An adjuster adjusts the height of the sliding boxes. The screw members are screwed into vertebral bodies in order to fuse the vertebral bodies together. A plurality of the self-drilling bone fusion screw apparatuses may be attached together and/or integrated via a plate or cage. Also disclosed is a cervical facet staple that includes a curved staple base and at least two prongs attached to the bottom surface of the curved staple base.
