Abstract: An orthopedic button assembly providing the ability to perform a soft tissue repair or bone repair using a method for securing sutures or fixation members in a knotless manner is described. The orthopedic button assembly of the present disclosure is designed in a manner to as to not rely on an additional component to perform the locking. The orthopedic button assembly of the present disclosure includes the ability to optimally tension the repair by pulling the tensionable fixation members (e.g. sutures) in the tensioning direction and prevent slippage of the tensionable fixation members in the opposite direction by capturing the tensionable fixation members in a manner such that pulling on the tensionable fixation members in the direction opposite of the tensioning direction (e.g., if connected tissue or bone were to attempt to “pull away” from the button assembly under tension) actually increases the tension, resulting in a tighter locking interface to increase the security of the repair.

Abstract: In one embodiment, a computing system may receive an uncompressed image from a camera. The computing system may generate a compressed image by performing a compression process on the uncompressed image, wherein a decompressed image may be generated as a byproduct during the compression process.

The computing system may generate, by the machine-learning model, an output based on the decompressed image. The computing system may provide operational instructions to a vehicle based on the output.

Abstract: A locking device or button configured for use with a tensionable fixation member to stabilize, fix, repair bone or soft tissue is described herein. By way of example, the locking device of the present disclosure allows for optimal tensioning of the repair or construct. The locking device of the present disclosure provides repair security and prevents loosening of the repair construct by allowing passage and tensioning of the tensionable fixation member when the tensionable fixation member is pulled through the locking device in a first direction (e.g., the “tensioning direction”), and preventing passage and loosening of the tensionable fixation member (e.g. locking the tensioning member) when the tensionable fixation member is pulled in a second direction (e.g., the “opposite direction” or “loosening direction”), without the need for a secondary locking element.

Abstract: A modular polyaxial bone screw includes a poly-axial bone screw, a polyaxial tulip head, and a collet disposed within the tulip head, the collet interacting with the bone screw and tulip head providing an interference fit with the bone screw head to lock orientation of the tulip head on and relative to the bone screw. Inner configurations of the tulip head interact with outer configurations of the collet to lock axial and/or rotational position of the collet within and relative to the tulip head, and thus about the bone screw head. The collet also has a resilient, tapered base with a plurality of slots in and about its end that allow the end to splay outwardly over and upon the head of the bone screw to create a snap or frictional interference fit between the splayed collet and the bone screw head when a spine rod is fixed in the tulip head.

Abstract: A system and method comprising an anchor assembly including an anchor and a locking element, a tensionable fixation member (e.g., surgical suture, tape, etc.), and a release member, wherein the anchor further comprises a first end, second end and anchor body. This re-tensionable anchor is designed to be implanted into bone. One end of a suture or other tensionable fixation member is attached to the tissue on one end to assist with fixation of soft tissue. Once the anchor has been seated in the bone, the second end of the suture or tensionable fixation member is pulled through a “one-way only” passage in body of the anchor. When the tensionable fixation member enters the body of the anchor, it traverses past by bending or deflecting out of the way a locking element within the anchor that will permit passage of the suture and will stay in contact with the fixation member via elastic compression that results from the elastic bending or deflection but prevent it from passing back.
