  • Publication number: 20240138884
    Abstract: A surgical instrument includes a body, a securement arm, a clamp lock, and a tensioning assembly. The body defines a longitudinal axis and has proximal and distal portions. The distal portion defines a recess. The securement arm is coupled to the body and translatable along the body in a direction parallel to the longitudinal axis between first and second position. The clamp lock is pivotally coupled to the distal portion of the body. The clamp lock is pivotable between secured and unsecured configurations. The tensioning assembly translatable in a direction parallel to the longitudinal axis between proximal and distal position. The tensioning assembly configured to draw a flexible band to tension the flexible band about a bony element.

  • Patent number: 11439443
    Abstract: A rod reducer includes a housing, an anvil, a locking anvil configured to engage a locking plug of a bone screw assembly, an arm assembly, a reducing screw extending through the housing and rotatably coupled with the anvil, and a locking screw extending through the housing and rotatably coupled with the locking anvil. The arm assembly includes an arm hingedly coupled to the housing, and first and second grasping members configured to engage the bone screw assembly. The first and second grasping members are hingedly coupled to the housing and extend through the anvil. Rotation of the reducing screw transitions the arm assembly between an open position, in which, distal portions of the arm and the first and second grasping members are radially expanded, and a closed position, in which, the distal portions of the arm and the first and second grasping members are radially contracted.

  • Publication number: 20220202454
    Abstract: A tether tensioner includes a handle assembly, an elongate member extending distally from the handle assembly, and an engaging portion. The handle assembly includes a stationary member, a trigger pivotably coupled to the stationary member, and a spool rotatably supported on the stationary member. The spool is configured to wrap a tether thereabout. The spool is operatively coupled with the trigger such that pivoting of the trigger relative to the stationary member causes rotation of the spool. The elongate member includes a channel configured to slidably receive a tether therethrough. The engaging portion is configured to receive a head portion of a bone screw such that a tether extends from the head portion disposed in the engaging portion to the spool through the channel of the elongate member.

  • Publication number: 20210267583
    Abstract: A surgical access system includes a connector including an arm, a coupling element, a rod, and a ridged slider. The arm includes first and second notched sections disposed in opposed lateral sides thereof. The coupling element includes a body section defining an opening therethrough, and opposed tabs protruding therefrom that are configured to receive the second notched section therebetween such that the arm is pivotably coupled to the coupling element. The rod includes a shaft having a plurality of angled grooves defined partially along a length thereof. The rod extends through the opening of the coupling element and the first notched section of the arm. The ridged slider includes a first surface having a plurality of ridges extending along a partial length thereof. The ridged slider extends through the coupling element with the plurality of ridges operably engaged with the plurality of angled grooves of the rod.
