Patent number: 11963700Abstract: An anchor can be coupleable to a bone, where the anchor includes a head, a shank, a first extension, and a second extension. The head can include a distal head portion and a proximal head portion, where the proximal head portion can be open at a proximal end of the head. The shank can extend distally from the distal head portion, where the shank including a threaded portion configured to engage the bone. The second extension can be opposing the first extension, and the second extension can include a second proximal support coupled to a second end of a first elongate portion, where a first proximal support can extend transverse to the longitudinal axis, and the first proximal support portion and the second proximal support portion can be separated in a first condition and can be engaged to transfer forces there between in a second.Type: GrantFiled: August 11, 2021Date of Patent: April 23, 2024Assignee: Zimmer Biomet Spine, Inc.Inventors: Heidi Farmer, Jared Parker, Randall G.

Patent number: 11678913Abstract: A surgical derotator instrument comprises a shaft, a handle and an articulating coupler. The shaft comprises a first end portion having a bone anchor coupling and a second end portion opposite the first end portion. The handle comprises a body portion and a slot extending in the body portion. The articulating coupler connects the shaft and the handle. A method for coupling a plurality of derotator instruments into a series of derotator instruments comprises: attaching a plurality of derotator instruments to a plurality of adjacent bone anchor housings, each derotator instrument comprising: a shaft for connecting to a bone anchor housing, a handle having a slot, and an adjustable coupler connecting the shaft and the handle; adjusting one or more of the adjustable couplers to align at least one of the slots of the series with other slots of the series; and inserting an elongate member through the at least one slots that are aligned.Type: GrantFiled: November 6, 2019Date of Patent: June 20, 2023Assignee: Zimmer Biomet Spine, Inc.Inventors: Heidi Farmer, Jared Parker, Chad Coxon

Publication number: 20230157735Abstract: A sleeve can be adapted to reinforce a bone anchor, and can include a body, a lock, and an actuator. The body can include a first sleeve arm and a second sleeve arm, where each can extend longitudinally along opposing sides of a longitudinal bore open at a distal end of the sleeve. The lock can be coupled to the body and releasably securable to a channel of a head of the bone anchor to secure the sleeve to the anchor.Type: ApplicationFiled: January 23, 2023Publication date: May 25, 2023Inventors: Heidi Farmer, Jared Parker

Publication number: 20230052647Abstract: A reducer comprises a reducing shaft for engaging a stabilization member, a reducer body for engaging a pedicle screw extender and receiving the reducing shaft along an axis, and one or more of a three-pawl clutch mechanism, a three-stage locking mechanism and a closure mechanism. The clutch mechanism comprises a clutch housing comprising a central passage into which the reducing shaft extends and ports intersecting the central passage, a clutch knob surrounding the clutch housing, and clutch pawls disposed within the ports. The locking mechanism attaches the reducer body to the pedicle screw extender and comprises a first pivoting lever comprising a toothed end, a second pivoting lever comprising a socket for engaging the tooth, and a protrusion configured to engage the pedicle screw extender. The closure mechanism comprises a driver shaft extending through the reducing shaft and a biasing element to bias the driver shaft to a retracted position.Type: ApplicationFiled: August 12, 2022Publication date: February 16, 2023Inventors: Douglas Brooke, Heidi Farmer, Guillaume Quetier, James Vincent Eaton, Larry T.

Publication number: 20220022925Abstract: A tool for breaking tabs of a vertebral bone anchor can include a tip, a first rail, and a second rail. The tip can be positionable over a housing of a vertebral bone anchor. The first rail can be pivotably coupled to the tip and can extend proximally away from the tip. The first rail can be configured to receive a first extended tab therein. The first rail can be pivotable with respect to the tip between a first upright position and a first outward position to break the first extended tab from the housing. The second rail can be pivotably coupled to the tip and can extend proximally away from the tip.Type: ApplicationFiled: July 22, 2021Publication date: January 27, 2022Inventors: Caleb Lee Stoll, Randall G. Mast, Allison Christine Capote, Heidi Farmer, Guillaume Quetier, Daniel Burke
