Tool assemblies, system, and methods for manipulating tissue and methods for performing a surgical procedure on a vertebral body adjacent soft tissue. A manipulator moves an end effector, and a screw is coupled to the end effector. A sleeve is disposed coaxially around the screw, and the screw and the sleeve are releasably engaged to one another. A navigation system is configured to track the vertebral body, and one or more controllers control the end effector to advance the screw relative to the sleeve along an insertion trajectory defined with respect to a surgical plan. The screw disengages the sleeve during advancement, and the screw is secured to the vertebral body. A distal working portion of the screw may be freely slidable through a distal end of the sleeve when disengaged. The screw may be a tap marker removably couplable with a tracking device of the navigation system.

Tool assembly, systems, and methods for manipulating tissue

A tool for creating an incision at a surgical site includes a body for use with a robotic end effector having a proximal end and a distal end, and a blade positioned at the distal end of the body, the blade having a proximal end and a distal end, the blade having a cutting edge defining a first portion extending outwardly from or adjacent to the proximal end to a maximum width and a second portion extending inwardly from the maximum width to a sharp distal tip.

Incision tools and methods of use

A stylet control system for selectively advancing and retracting a stylet includes a stylet having a first end and a second end, the second end being threaded, a screwdriver defining a bore for receiving a portion of the stylet and having a screw-engaging end for engaging a screw, the stylet being rotationally fixed relative to the screwdriver. The system includes a control device having a passage for receiving the screwdriver and having an inner portion defining a lumen for receiving the portion of the stylet, the inner portion being threaded for engaging the threaded second end of the stylet, when the screwdriver is rotated in the first rotation direction and the control device is prevented from rotating, the screwdriver advances the screw in the first axial direction and the stylet retracts in a second axial direction, opposite the first axial direction.

Bone screws, instrumentation, and methods of using of same

An angled fixation device, such as an angled screw. This angled fixation device may be used by the surgeon to secure a spacer to a spinal disc space. The proximal end portion of the angled fixation device is driven perpendicular to the anterior wall of the spacer, and so is parallel to the vertebral endplates and in-line with the inserter. The distal end portion of the angled fixation device is oriented at about a 45 degree angle (plus or minus 30 degrees) to the vertebral endplate it enters.

Stand alone intervertebral fusion device

Disclosed herein are devices and methods for removing tissue. In one aspect, a device for removing tissue includes a hollow elongate member having an outer wall and a lumen, a selectively deployable tissue-cutting element extending from the hollow elongate member, and an actuation member extending through the lumen and coupled to the hollow elongate member at a location that is distal to the tissue-cutting element. Movement of the actuation member can cause the tissue-cutting element to move from the insertion configuration where the tissue-cutting element is not deployed to a tissue-cutting configuration where the tissue-cutting element is deployed such that it is radially extended relative to the insertion configuration.

Disc nucleus removal devices and methods

Driver instruments are disclosed herein with various features for improving usability, easing the task of cleaning or sterilizing the instrument, reducing patient trauma associated with use of the instrument, and/or reducing the cost and assembly burden of the instrument. For example, a driver instrument can include a guide sleeve to protect patient tissue from damage caused by rotating components of the instrument or a bone anchor assembly coupled thereto, and to protect extension tabs of the bone anchor assembly from inadvertent separation. By way of further example, an instrument can include a preload assembly for maintaining engagement of a driver shaft of the instrument with a bone anchor assembly. As yet another example, an instrument can consist of a small number of components which are configured for simple, tool-free assembly and disassembly. An instrument can also be configured for use with bone anchor assemblies with and without extension tabs.

Driver instruments and related methods

A spinal marking system includes a marker having a threaded member and a flexible member connected to the threaded member. The flexible member has a length longer than that of the threaded member. The system also includes a navigation tool having a shaft configured to connect to the threaded member. The navigation tool also includes a navigation array connected to the shaft. The navigation array having a plurality of fiducials that are configured to communicate with a robotic system.

Tap marker with flexible extension and associated instruments

A method of replacing a nucleus pulposus material wherein curable nucleus pulposus material is injected into a balloon in an intervertebral space.

Method of implanting a curable implant material

Devices and methods for aligning the components of polyaxial screws are described herein. In one embodiment, an alignment instrument includes an elongate frame having a longitudinal axis and a plurality of connection caps slidably disposed along the elongate frame. Each connection cap can removably couple to a polyaxial screw extension tube and selectively lock relative to the elongate frame such that a distance between the plurality of connection caps and an angular orientation of each connection cap relative to the elongate frame is maintained. The instrument can also include a transverse angle indicator to indicate an angular orientation of the elongate frame in a plane transverse to the longitudinal axis of the elongate frame. The device can, for example, capture the orientation of a plurality of polyaxial screws during spinal surgery such that the screws can be returned to the same orientation after manipulation to correct a spinal deformity, etc.

Methods and devices for polyaxial screw alignment

Methods and devices are provided for using a bone anchor driver for driving inner and outer set closure mechanisms or set screws into a bone anchor assembly. In one embodiment, a bone anchor driver is provided that includes an outer shaft configured to engage an outer set screw coupled to a bone anchor assembly, an inner shaft disposed within the outer shaft and configured to engage an inner set screw coupled to the bone anchor assembly, and a torque limiting mechanism configured to automatically switch between a first position in which it is disengaged from the inner shaft and is engaged with the outer shaft, and a second position in which it is disengaged from the outer shaft and is engaged with the inner shaft.

Bone anchor driver and methods

A method of replacing a nucleus pulposus material wherein curable nucleus pulposus material is injected into a balloon in an intervertebral space

Devices and methods for selectively converting polyaxial bone screws into monoaxial screws are described herein. In one embodiment, a spinal screw extension instrument is provided having an outer component configured to engage a receiving member of a polyaxial screw. The instrument further includes an inner component disposed within an inner lumen of the outer component and configured to translate longitudinally relative to the outer component such that the inner component can apply a distal force to a compression member of the polyaxial screw disposed within a distal portion of the receiving member to thereby convert the polyaxial screw to a monoaxial screw.

Devices and methods for monoaxial screw conversion

Bone anchor assemblies and methods are provided having a multi-component bone anchor that is configured to allow the shank of the bone anchor to be bottom loaded into a receiver member. In one embodiment, a bone anchor assembly is provided having a shank with a distal threaded portion and a proximal head portion, a ball having a spherical exterior surface and a central lumen sized to receive the head portion of the shank, and a clip configured to be engaged between the head portion and the ball such that the clip is effective to lock the ball in engagement with the shank.
