Patent number: 11439443Abstract: 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.Type: GrantFiled: October 17, 2019Date of Patent: September 13, 2022Assignee: K2M, Inc.Inventors: Kan Min, Brian Kunes

Patent number: 10624675Abstract: A spinal stabilization system includes a spinal rod, a plate, a set screw, and a bone screw. The plate includes a throughhole transitionable between a collapsed and expanded configuration, and a first slot adapted to receive a spinal rod therein. The set screw includes a distal portion having threads to engage with a threaded lumen of a bone screw, and the bone screw including a head portion transitionable between a first diameter and a second diameter. The head of the bone screw insertable into the throughhole and cooperatively transitions between the first diameter and the collapsed configuration to the second diameter and expanded configuration, respectively, as the set screw advances with respect to the bone screw to lock the spinal rod into the slot of the plate in the second diameter and expanded configuration.Type: GrantFiled: June 12, 2017Date of Patent: April 21, 2020Assignee: K2M, Inc.Inventors: Robert Gaines, Kan Min, Brandon Moore

Patent number: 10390861Abstract: A spinal stabilization device includes a rod receiving member, a collet, a plug, and a first bone screw. The rod receiving member defines a first throughhole, a collet recess aligned with the first throughhole, and a rod receiving slot offset from the first throughhole. The collet is insertable into the collet recess and defines an aperture, a plug recess aligned with the aperture, and a wall portion defining a rod securing slot configured to fix the spinal rod therein. The collet is transitionable between a first diameter, where the rod securement region defines a first diameter, and a second diameter, where the rod securement region defines a second diameter. The plug is insertable within the plug recess, and transitions the collet between the first and second diameters. The first bone screw includes a head portion and a threaded portion, and is insertable through the rod receiving member and the collet.Type: GrantFiled: July 26, 2017Date of Patent: August 27, 2019Assignee: K2M, Inc.Inventors: Laurel Blakemore, Robert Gaines, Rune Hedlund, Jwalant Mehta, Kan Min, Hilali Noordeen, Brandon Moore
