A surgical device includes a plurality of cameras integrated therein. The view of each of the plurality of cameras can be integrated together to provide a composite image. A surgical tool that includes an integrated camera may be used in conjunction with the surgical device. The image produced by the camera integrated with the surgical tool may be associated with the composite image generated by the plurality of cameras integrated in the surgical device. The position and orientation of the cameras and/or the surgical tool can be tracked, and the surgical tool can be rendered as transparent on the composite image. A surgical device may be powered by a hydraulic system, thereby reducing electromagnetic interference with tracking devices.

A minimally invasive spinal instrument and method for use of the same are disclosed. In some embodiments, a body includes an outer shaft and an inner shaft. A passageway accepts the inner shaft such that the outer shaft at least partially encloses the inner shaft. Each of the outer shaft and the inner shaft have spaced rings with locking grooves interleaved therewith. Each set of locking grooves is sized to accept a clamp such that the spaced rings mitigate longitudinal sliding of the clamp. A locking knob selectively secures the outer shaft and inner shaft thereto. A tip is removably secured to the inner shaft. In a single shaft configuration, in response to the locking knob being selectively disengaged from the outer shaft, the inner shaft and the locking knob are separated from the outer shaft such that the passageway is accessible to accept a metallic wire therethrough.

The invention provides a targeting device suitable for use in removing a femoral implant from the surrounding tissue, wherein the device comprises: (A) an anterior guide member (1), (B) a posterior guide member (4), (C) an engagement member (7), (D) a first pair of parallel connector rails (509, 510), and (E) an adjustment system (13). When the anterior guide member and the posterior guide member are connected by the first pair of connector rails, via the engagement member, the angled channels of the anterior guide member and the posterior guide member converge in the direction of a distal end, with the convergence angle of the angled channels being in the range of from 2 to 6 degrees, such as from 2 to 5 degrees.

In general, orthopedic instrument adapters and methods of using orthopedic instrument adapters are provided. In an exemplary embodiment, an adapter is configured to releasably attach to an end effector configured to impact bone. The end effector can be a broach, chisel, or other surgical implement. The adapter includes a spring-loaded hook that is configured to releasably seat in a cut-out formed in the end effector. The adapter is also configured to releasably attach to a surgical impacting tool, such as an orthopedic impactor, configured to drive impacting of the end effector relative to bone.

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.

Disclosed herein is a surgical tool for debulking hard tissue. The surgical tool includes: (i) an elongated hollow member including a distally located bent section; (ii) a cable extending within the hollow member, along a predetermined length thereof; (iii) a headpiece positioned at, or distally to, the bent section; (iv) a rotation actuator coupled to the cable proximal end and configured to rotate the cable about a longitudinal axis thereof; and (v) a motion converter coupled to a distal end of the cable and to the headpiece, at least part of the motion converter is positioned in, and/or distally, to the bent section, the motion converter being configured to transform rotational motion of the cable into an axial, reciprocating motion of the headpiece. The headpiece is configured to break up hard tissue by hammering thereof, when effecting axial, reciprocating motion, while simultaneously minimizing damage to soft tissue if struck.

An example method includes obtaining, a virtual model of a portion of an anatomy of a patient obtained from a virtual surgical plan for an orthopedic joint repair surgical procedure to attach a prosthetic to the anatomy; identifying, based on data obtained by one or more sensors, positions of one or more physical markers positioned relative to the anatomy of the patient; and registering, based on the identified positions, the virtual model of the portion of the anatomy with a corresponding observed portion of the anatomy.

A device for accessing and guiding at least one fixation device to a spine may include a distal portion configured to fit in a facet of the spine and a proximal portion extending from the distal portion. The proximal portion may be detachable from the distal portion and may be hollow or solid. A system for accessing and guiding at least one fixation device to a spine may include a distal portion configured to fit in a facet of the spine, a proximal portion extending from the distal portion, and a slidable guide device for sliding over the facet guide device to guide at least one instrument to the spine.

In various embodiments, an implant for interfacing with a bone structure includes a web structure including a space truss. The space truss includes two or more planar truss units having a plurality of struts joined at nodes and the web structure is configured to interface with human bone tissue. In some embodiments, a method is provided that includes accessing an intersomatic space and inserting an implant into the intersomatic space. The implant includes a web structure including a space truss. The space truss includes two or more planar truss units having a plurality of struts joined at nodes and the web structure is configured to interface with human bone tissue.

A driving pin can be used for installing a bone plate on a bone. In some examples, the driving pin has a driving pin body extending from a proximal end to a distal end. The driving pin body may define at least three regions of different cross-sectional thickness, including a bone penetrating region adjacent the distal end, a driving region adjacent the proximal end, and a bone plate orienting region between the bone penetrating region and the driving region. In general, the bone penetrating region has a smaller cross-sectional thickness than the bone plate orienting region and the bone plate orienting region has a smaller cross-sectional thickness than the driving region. The bone plate orienting region may be sized to conform to the size of a fixation hole extending through bone plate.
