  • Patent number: 11583360
    Abstract: One variation of a method for tracking objects within a surgical space during a surgery includes: based on a first image depicting the surgical space at a first time, detecting a first object and a constellation of objects in the surgical space, estimating distances from each object—in the constellation of objects—to the first object, and calculating a contamination risk of the first object based on contamination scores and distances to the first object for each object in the constellation of objects; calculating a contamination score of the first object based on a combination of the contamination risks of the first object during the surgery; and, in response to the contamination score of the first object exceeding a threshold contamination score prior to contact between the first object and a patient, serving a prompt within the surgical space to address sterility of the first object.

  • Patent number: 11534213
    Abstract: Variable angle holes in bone plates that are structured to facilitate the formation of axial compression or tension of a bone, or which can assist in bone distraction. The variable angle hole can extend about a central axis and includes an inwardly extending wedge wall. The variable angle hole can be sized to receive insertion of a fixation element at a location at which a central longitudinal axis of the fixation element is axially offset from the central axis of the variable angle hole by an offset distance at least when the fixation element is initially driven into bone at least in a transverse direction. The wedge wall can be configured to be engaged by a portion of the fixation element in a manner that axially displaces at least one of the bone plate, the fixation element, and/or bone(s) in a direction that can generally reduce or increase the offset distance.

  • Patent number: 11523852
    Abstract: A first bone portion may be secured to a second bone portion by forming a hole in the first bone portion and the second bone portion and inserting a bone screw into the hole. The bone screw may have a proximal member, a distal member, and a tension member with a proximal end coupled to the proximal member and a distal end coupled to the distal member. Torque may be applied to the bone screw to move the distal member away from the proximal member such that the tension member elongates and urges the distal member to move toward the proximal member. The torque may be transmitted from the proximal member to the distal member via a torque transmission feature. A bending transmission feature, displaced proximally or distally from the torque transmission feature, may be positioned to share bending loads between the proximal member and the distal member.

  • Patent number: 11510718
    Abstract: A universal wire driver attachment comprises a driveshaft forming a lumen extending along a longitudinal axis. The driveshaft forms a plurality of channels extending perpendicularly from the longitudinal axis. The attachment further comprises a plurality of primary jaws movably disposed at least partially within the channels. The primary jaws comprise a plurality of wire gripping surfaces facing the longitudinal axis and configured to grip the surgical wire. The primary jaws cooperate with the channels such that the primary jaws are constrained from moving in an axial direction along the longitudinal axis. The primary jaws are capable of moving outward from the longitudinal axis when the surgical wire is inserted between the primary jaws, and the primary jaws are capable of being urged inward toward the longitudinal axis by the securing mechanism to increase a grip force on the surgical wire.

  • Patent number: 11510686
    Abstract: A drill assembly for creating a reverse counterbore bone tunnel while increasing bone preservation. The drill assembly including a housing having an actuation mechanism and a cannulated shaft connected to the actuation mechanism. The drill assembly also includes a rigid rod extending through the cannulated shaft. Engaging the actuation mechanism moves the cannulated shaft along the rigid rod. The drill assembly additionally includes a distal tip connected to the cannulated shaft and the rigid rod. Proximal movement of the cannulated shaft along the rigid rod causes the distal tip to rotate from a first configuration to a second configuration. In the second configuration, the distal tip extends at an angle relative to the cannulated shaft.
