A surgical instrument comprises a first portion defining a cavity configured for disposal of a first implant support member. A second portion defines at least one passageway aligned with the cavity and including a guide engageable with a second implant support member to orient the second implant support member with the at least one passageway such that the second implant support member is connectable with the first implant support member. Systems, spinal constructs, spinal implants and methods are disclosed.

Minimally invasive compressor / distractor

A compressor/distractor instrument that provides internal set screw engagement for threaded reduction capabilities while also providing bending support of the screw extenders during compression or distractor manipulation. Threaded reduction is performed by engaging compressor/distractor support tubes at the proximal end with a compressor/distractor driver. A removable locking pull pin secures the left and right handles of the compressor/distractor driver together during use, and removal of the pin releases the compression and tension built up in the device for ease of removal.

An assembly for performing surgical procedures may include a sleeve comprising: an elongate main body, a channel extending within a length of the elongate main body; a fixation member having been preloaded in the sleeve; and a bone fastener comprising: a shaft configured to engage bone, a tulip configured to receive a rod, a retention feature and extended tabs extending from the tulip.

Surgical instrument with integrated compression and distraction mechanisms

Embodiments disclosed herein provide compression/distraction methods and tools useful for fitting a spinal stabilization system in a patient through minimally invasive surgery. The spinal stabilization system may comprise screws anchored in vertebrae. The vertebrae may need to be compressed or distracted. One embodiment of an instrument disclosed herein may comprise a shaft for engaging one of the screws through an extender sleeve. A driver may engage another screw through an opening of the instrument. Through this engagement, a surgeon may use the rack and pinion of the instrument to compress or distract one or more levels of the vertebrae in a parallel motion, which can be advantageous clinically in certain situations.

Percutaneous spinal cross link system and method

A percutaneous spinal cross link system for interconnecting a spinal fusion construct on one side of the longitudinal axis of the spine with a spinal fusion construct on the other side of the longitudinal axis may include a cross bar connected at each end by a respective connector to a respective spinal fusion rod of each of the spinal fusion constructs. The connector may include a rod receiving portion adapted to receive one of the spinal fusion rods and a cross bar receiving portion adapted receive the cross bar in an orientation generally perpendicular to the spinal fusion rod. A cannula defined by two spaced apart blades may be connected to the connector for defining a minimally invasive pathway through body tissue for introduction of the cross bar to the connector. Other tools for use with the system are also disclosed.

POLYAXIAL BONE ANCHOR WITH NON-PIVOTABLE RETAINER AND POP-ON SHANK, SOME WITH FRICTION FIT
20170333086 · 2017-11-23 ·

A polyaxial bone screw assembly includes a threaded shank body having an integral upper portion receivable in a receiver, the receiver having an upper channel for receiving a longitudinal connecting member and a lower cavity cooperating with a lower opening. The upper portion expands a retaining member in the receiver cavity to capture the shank upper portion in the receiver. In some embodiment either the retaining member or an insert provide for a friction fit of the shank upper portion in the receiver resulting in non-floppy placement of the shank with respect to the receiver. Some retainers and inserts have a lock-and-release feature. Final locking of the polyaxial mechanism is provided by frictional engagement between the shank upper portion and the retaining member. A pre-assembled receiver, retaining member and optional insert may be popped-on or snapped-on to the shank upper portion prior to or after implantation of the shank into a vertebra.

SPINAL STABILIZATION DEVICE, SYSTEM, AND METHOD OF USE

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.

POLYAXIAL SCREW AND LOCKING CAP

Systems, methods, and devices for securing a spinal rod are provided. A clamp assembly comprises a tulip comprising an opening comprising an inner surface, wherein the inner surface is threaded; and a threaded locking cap disposed in the opening, wherein threads of the locking cap and the inner surface include various geometries.

SURGICAL IMPLANT POSITION DETECTION
20230165606 · 2023-06-01 ·

Systems, methods, and devices are disclosed for surgical systems comprising an applicator having a first shaft, an implant having a first member pivotably and detachably coupled to the first shaft, and a second member for converting rotational motion of the implant to a translational offset, and at least one of a sensor for determining the offset or an indicator for indicating the offset, provided that the indicator is not a protrusion located at an end of the applicator. A controller may be provided, the controller being configured to receive offset data from the sensor, determine an angle of the implant in a patient using dimensions of the implant and the offset, and display a current position of the implant relative to patient anatomy. The applicator may have a second shaft slidably disposed on the first shaft along an axis defined by a longitudinal axis of the applicator.

Dynamic spinal stabilization assemblies, tool set and method
09788868 · 2017-10-17 ·

A hinged bone screw and tool set is used for implanting such bone screws in a human spine, followed by the implantation of a longitudinal connecting member into the bone screws. The hinged bone screw includes a shank with an upper portion and a receiver with integral arms forming a U-shaped channel. A lower curved seat partially defining the U-shaped channel cooperates with an upper portion of the bone screw shank for hinged movement of the shank with respect to the receiver. The tool set includes an insertion tool, a bone screw driver, a reduction tool and a closure starter. The insertion tool includes a bone screw attachment structure and a laterally opening channel. The insertion tool further includes a threaded portion for cooperation with the reduction tool to provide synchronized placement of a closure structure in the bone screw receiver while reducing and capturing a longitudinal connecting member within the receiver. Further alternative bone screws are hinged, polyaxial or fixed and include lordosing or kyphosing lateral surfaces.
