  • Publication number: 20220183725
    Abstract: Systems, instruments, and methods for performing a medical procedure. The methods comprise: obtaining a surgical instrument that combines a head positioner and a driver into a single integrated part (the driver being at least partially inserted through an elongate aperture formed in the head positioner so as to extend from a proximal end of the head positioner to a distal end of the head positioner); using an actuable structure of the head positioner to limit an amount that the driver can linearly travel in a first direction within the elongate aperture formed in the head positioner; causing a screw to threadingly engage an object via rotation of the driver in at least a first direction around a central axis of the surgical instrument; and changing an orientation of a receiver via rotation of the head positioner about a portion of the driver.

  • Patent number: 11291477
    Abstract: An implant system is disclosed. The system may include an implant receiver having a base and a first arm and a second arm extending from the base in a longitudinal direction towards an open end. The first arm and second arm may define a receiving cavity therebetween. The first and second arm may each include an outside thread pattern for rotatably supporting a nut movable in the longitudinal direction and an inside thread pattern for rotatably supporting a set screw movable in the longitudinal direction. A rod may be selectively positioned within the receiving cavity at an intermediate elevation between the base and the open end and the rod may be supported by the nut. The set screw may be tightened against the rod thereby locking the rod and nut at the intermediate elevation. In some embodiments, the first and second arms may include a plurality of breakoff locations.

  • Patent number: 11219473
    Abstract: A spinal-surgery system having a receiver for receiving a rod and/or a receiver cap. The cap has a generally cylindrical body and a set of opposing splay-resisting flanges extending radially from the body. The receiver has arms each having an inner proximal protrusion at or adjacent the proximal end, and an inner sloped splaying surface distal of the proximal protrusion. Each cap flange has a proximal-facing cap splay-prevent surface, and a distal-facing cap pop-on surface. Each receiver proximal protrusion has a proximal-facing sloped receiver pop-on surface, and a distal-facing sloped receiver splay-prevent surface. The receiver pop-on surfaces are spaced so each cap pop-on surface contacts a respective receiver pop-on surface in operation. Each splaying revision surface extends distally and radially inward toward the longitudinal axis and into a cylindrical plane defined by an inner diameter of the cap. The cap inner diameter is greater than a rod width.

  • Publication number: 20210401473
    Abstract: A spinal-surgery system having a rod receiver and/or a cap for use insertion and removal from the receiver. The cap has a generally cylindrical body, a set of opposing splay-resisting flanges, and set of opposing rotation-preventing wings, the flanges extending radially from the body along a first radial line of the body, and the wings extending radially away from the body along a second radial line of the body generally orthogonal to the first radial line. Each cap flange has a proximal-facing cap splay-resisting surface, and a distal-facing cap pop-on surface. Each receiver proximal protrusion has a proximal-facing sloped receiver pop-on surface, and a distal-facing sloped receiver splay-resisting surface. The receiver pop-on surfaces are spaced such that each cap pop-on surface contacts a respective receiver pop-on surface when the cap is centered, with the cap wings aligned between receiver arms, and moved distally to contact the receiver.

  • Patent number: 11191574
    Abstract: Systems, instruments, and methods for advancing a set screw in an object. The methods comprise: disposing a shank tip of a set screw reducer in a socket of the set screw; causing a sleeve integrated with the set screw reducer to slidingly engage a shank of the set screw reducer and move in a direction towards the shank tip; transferring torque from the set screw reducer to the set screw such that the set screw is advanced in a threaded hole of the object; and using the sleeve of the set screw reducer to substantially prevent splaying of at least one sidewall of the object while the torque is being transferred from the set screw reducer to the set screw.

  • Publication number: 20210298800
    Abstract: A spinal-surgery system having a rod receiver and/or a cap having a generally cylindrical body, a set of opposing splay-resisting flanges, and a set of opposing rotation-preventing/rotation-resisting wings. Each wing has a lateral rotation-preventing portion and a lateral rotation-resisting portion. A receiver proximal end forms a wing-receiving cavity having a lateral rotation-preventing side and a lateral rotation-resisting side. Each flange has a proximal-facing splay-resist surface, and a distal-facing pop-on surface. Each receiver proximal protrusion has a proximal-facing sloped receiver pop-on surface, and a distal-facing sloped receiver splay-resist surface. Each rotation-preventing portion contacts a corresponding rotation-preventing side and each rotation-resisting portion contacts a corresponding rotation-resisting sides when the cap is popped on. The rotation-preventing portions contacting the rotation-preventing sides prevents cap rotation in a first direction.
