A stylet screw driver assembly having a screw driver/ratcheting handle assembly which houses a stylet, pre-assembled to a set length based on the screw length in use, fixed in place by a spring loaded button mechanism located on the proximal end of the ratcheting handle. The spring loaded button mates with the stylet assembly, providing various stylet protrusion lengths.

Systems, methods, and instruments for tracking localized movement of an anatomic structure at a surgical site are provided that can, for example, detect and identify movement of the anatomic structure not otherwise tracked by a global navigation system. One embodiment can include a cannula with a localized navigation sensor coupled to a distal end thereof. The cannula can be coupled to a robot arm and the localized navigation sensor can detect movement of an anatomic structure relative to the cannula. The localized navigation sensor can include one or more tines that selectively extend from the cannula to contact the anatomic structure. A controller can receive data from the localized navigation sensor and a global navigation system, and determine if movement detected by the localized navigation sensor is tracked by the global navigation system. Systems, methods, and instruments of the present disclosure can be used independently of a global navigation system.

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.

Systems and methods for percutaneously installing a vertebral stabilization system. A first anchor is positionable within a body of a patient through a first percutaneous opening and a second anchor is positionable within a body of a patient through a second percutaneous opening. A stabilization member is positionable within the body of a patient through the first percutaneous opening to engage and connect the first and second anchors.

A bone fastener assembly instrument that can assemble a two-component bone fastener during surgery is provided. The bone fastener may be of a type that comprises a threaded bolt and nut for securing an implantable device to bone, such as a spinous process. A method for using the bone fastener assembly instrument is also provided.

The shim-type implant for distraction and fusion of cervical facet joints is provided. The implant has a generally box-like shape with a blunt leading edge that may be centered or offset to the inferior face. The implant may include a graft window for enhanced osseous through-growth after implantation. The implant is coated with hydroxyapatite (HA) and/or tri-calcium phosphate (TCP) to allow for osteo-conduction, is porous, and has a roughened surface with serrations on the superior and inferior faces. The implant may be fabricated from a titanium or tantalum alloy. In an embodiment, a set of tools is provided with a chisel and one or tongs and one or more decorticators for inserting the implant.

An external adjustment device includes at least one permanent magnet configured for rotation about an axis with a first handle extending linearly at a first end of the device and a second handle at a second end of the device, the second handle extending in a direction substantially off axis to the first handle. The external adjustment device further includes a motor mounted inside the first handle and a first button located in the proximity to one of the first handle or the second handle, the first button configured to be operated by the thumb of a hand that grips the one of the find handle or second handle. The first button is configured to actuate the motor causing the at least one permanent magnet to rotate about the axis in a first direction.

Systems are described for conducting minimally invasive medical interventions utilizing instruments and assemblies thereof to stabilize and/or fixate a dysfunctional sacroiliac (SI) joint. The systems include a drill guide having a bone dislodging member adapted to create a pilot SI joint opening in the dysfunctional SI joint through an incision comprising a length no greater than 3.0 cm; portions of the pilot SI joint opening being disposed in the sacrum and ilium bone structures. The drill guide includes a tri-mode fixation system adapted to position and stabilize the drill guide during creation of the pilot SI joint opening in the dysfunctional SI joint and delivery of the SI joint prosthesis therein. The systems also include a SI joint prosthesis configured to be inserted into the pilot SI joint opening of the dysfunctional SI joint, a prosthesis deployment assembly configured to engage the SI joint prosthesis and advance the SI joint prosthesis into the dysfunctional SI joint, and a bone harvesting assembly adapted to extract and collect dislodge bone material from the bone dislodging member after creation of the pilot SI joint opening.

Systems for the minimally invasive repair, stabilization and/or fixation of a fractured bone, such as a rib, are disclosed. The systems include one or more rods/support members that are designed to extend along a dimension of a bone being repaired and secure the fractured bone. The support members can be photodynamic and are formed using an expandable member that is filled with a light-sensitive liquid that is cured to form the rigid support member. Two or more clamps are used to secure the support member(s) to the rib or other bone. Minimally invasive surgical methods for securing the systems to a fractured bone are also disclosed.

A surgical system includes an instrument portal comprising a first proximal end, a first distal end, and a first elongated member, the first elongated member comprising a first bore defining a first diameter, wherein the first bore extends from the first distal end to the first proximal end, wherein the maximum clearance of the instrument portal is the first diameter, and a drill guide reducer configured to be inserted into the instrument portal, the drill guide reducer comprising an elongated cylindrical member defining an outside diameter such that the drill guide reducer is sized to fit within the instrument portal and defining an inner diameter configured to receive a drill guide, wherein the inner diameter of the drill guide reducer is smaller than the first diameter of the instrument portal.
