Various bone screws configured to be implanted into bone and methods of use are provided. In an exemplary embodiment, a bone screw is provided with an elongate shank and a head with a drive feature configured to couple with a driver tool for being advanced into bone and a threaded shank. The screw can have a distal end or tip that has one or more cutting edges thereon configured to cut bone as the bone screw is inserted into bone.

Bone screw

In general, surgical instruments described herein can include a handle assembly having an elongate shaft extending distally therefrom. The handle assembly can be configured to axially translate a carrier assembly that secures a stylet extending therethrough. Translation of the stylet can be made relative to a distal end of the elongate shaft. The surgical instruments can include various carrier assemblies for positioning the distal end of the stylet relative to the distal end of the elongate shaft based on a length of bone anchor to be installed by the surgical instrument.

Spinal screw insertion devices and methods

A system for delivering flowable biomaterial to an intervertebral disc space between adjacent vertebral bodies includes a delivery body defining a proximal end, a distal end spaced from the proximal end along a longitudinal direction, a cannulation extending from the proximal end to an opening adjacent the distal end, and a distal region including a tip that extends to the distal end. The distal region defines a maximum height at a location proximal of the distal end and measured along a second direction perpendicular to the longitudinal direction. The distal region is for indicating a distance between the adjacent vertebral bodies. The system includes a carrier having a longitudinally elongate channel for carrying biomaterial and being insertable within the cannulation, as well as an advancement member configured for insertion within the cannulation to forcibly advance the biomaterial from the cannulation, through the opening, and into the disc space.

Biomaterial delivery device, and related systems and methods

Screw inserter instruments and methods for implanting a bone screw are disclosed herein. In one exemplary embodiment, a screw inserter instrument can include a screw drive assembly having a first handle and a driver shaft coupled to the first handle, and a stylet assembly having a second handle and a stylet extending through the driver shaft. The first handle can have a locked configuration, in which the first handle and the driver shaft are coupled such that the first handle can maintain the driver shaft in a fixed position while the second handle is rotated relative to the first handle, and an unlocked configuration, in which the first handle and the driver shaft can rotate simultaneously in a first direction and the first handle can rotate independent of the driver shaft in a second opposite direction.

Screw inserter instruments and methods

In an embodiment, a system attaches a patient reference array of a computer-assisted surgery system to a patient. The system includes a fixation post having a shaft having proximal and distal ends that are offset from. A threaded fastener is coupled to the shaft at the distal end that rotates relative to the shaft so as to engage internal threads of a pedicle screw, thereby causing the distal end of the shaft to translate in the anchor seat and urge the pedicle screw to transition from an unlocked configuration to a locked configuration. The attachment assembly has an arm that supports the patient reference array, and a coupler supported by the arm. The coupler has a fixation body that defines a recess that receives at least a portion of the fixation post, and an actuator that secures the attachment assembly to the fixation post.

Access port cutters and related systems and methods can be used to cut an access port to a desired length based on particular patient and/or surgical procedure needs at a point of use. More particularly, an access port cutter can include a base with an opening that can receive an access port therein such that a desired length of the access port can extend from the opening. An actuation mechanism can translate a blade linearly along at least a portion of the base such that the blade can traverse the opening and cut across the access port. In some embodiments, the actuation mechanism can include a handle that can pivot relative to the base to drive the blade. One or more safety features can reduce the risk of inadvertent actuation of the blade and/or prevent debris from contaminating a surgical site or falling onto a patient.

Access port cutters and related methods

Connectors for connecting or linking one instrument or object to one or more other instruments or objects are disclosed herein. In some embodiments, a connector can include a first arm with a first attachment feature for attaching to a first object, such as a surgical access device, and a second arm with a second attachment feature for attaching to a second object, such as a support. The connector can have an unlocked state, in which the position and orientation of the access device can be adjusted relative to the support, and a locked state in which movement of the access device relative to the support is prevented or limited. Locking the connector can also be effective to clamp or otherwise attach the connector to the access device and the support, or said attachment can be independent of the locking of the connector.

Surgical instrument connectors and related methods

The present disclosure relates to methods and devices for surgically manipulating tissue. In general, the methods and devices can include an elongate retractor shaft having a distal retractor tip that is configured to manipulate tissue, for example the tip can be configured to separate muscle and nerve fibers surrounding a vertebra. The elongate retractor shaft can include an illumination source such that at least a portion of the surgical field is illuminated by the device when the device is used in the body. A sensor can also or alternatively be included on the elongate retractor shaft, for example on the blunt retraction tip, such that the sensor can monitor physiological parameters of the tissue in or adjacent to the surgical field.

Surgical retractors

Bone anchors and surgical instruments (e.g., bone taps, drivers, etc.) are disclosed herein that include integrated guide tips. Use of these anchors or instruments can eliminate one or more of the steps in a conventional bone anchor installation procedure, improving surgical efficiency and safety. For example, a surgical instrument can include a guide projection configured for insertion through a cannulation formed in a bone anchor when the surgical instrument is coupled to the bone anchor. The surgical instrument can also include various mechanisms for adjusting the position of the guide projection relative to the bone anchor. The guide projection can replace the needle, stylet, and guidewire used in typical insertion procedures. The bone anchor can also include integrated tapping features to eliminate the need for a separate bone tap instrument. Thus, in some embodiments, targeting, tapping, and driving the bone anchor can be performed in a single step.

Bone anchors and surgical instruments with integrated guide tips

A separate nub component between the plate and an intervertebral fusion cage, wherein the nub is attached to the plate. The nub lessens the undesired pivotal movement of the plate. It is believed that when the nub fits snugly between the endplates of the adjacent vertebral bodies, it acts as a stop against the undesired pivotal movement of the plate.

Nubbed plate

Surgical instruments and methods for delivering bone anchor assemblies into bone are disclosed herein. Use of these anchors or instruments can eliminate one or more of the steps in a conventional bone anchor installation procedure, improving surgical efficiency and safety. In general, a surgical instrument can include a handle assembly having an elongate shaft extending distally therefrom. The handle assembly can be configured to axially translate a carrier assembly that secures a stylet extending therethrough. Translation of the stylet can be made relative to a distal end of the elongate shaft. The surgical instruments can include various carrier assemblies for positioning the distal end of the stylet relative to the distal end of the elongate shaft based on a length of bone anchor to be installed by the surgical instrument.

The surgical instruments can include various mechanisms for adjusting the position of the stylet.
