A drill guide fixture may be configured to prepare a skull for attachment of a cranial insertion fixture. The drill guide fixture may include a central drill guide and a bone anchor guide at a base of the drill guide fixture. The central drill guide may define a central drill guide hole therethrough, wherein the central drill guide hole has a first opening at a base of the drill guide fixture and a second opening spaced apart from the base of the drill guide fixture. The bone anchor drill guide may define a bone anchor drill guide hole therethrough, and the bone anchor drill guide hole may be offset from the central drill guide hole in a direction that is perpendicular with respect to a direction of the central drill guide hole. Related cranial insertion fixtures, robotic systems, and methods are also discussed.

A low-profile cranial device is adapted for covering and protecting electrical leads. The cranial device includes a static cranial implant shaped and dimensioned for housing a functional neurosurgical implant including electrical leads. The static cranial implant includes an outer first surface along an exterior side of the static cranial implant, an inner second surface along an interior side of the static cranial implant, and a peripheral wall extending between the outer first surface and the inner second surface. A cavity is formed along the outer first surface of the static cranial implant, the cavity being shaped and dimensioned to house the functional neurosurgical implant in a manner allowing the electrical leads to be wound up to store excess electrical lead length.

This disclosure relates to drill guides and depth control apparatus for use with a variety of customized or standardized surgical instruments. In embodiments, the apparatus comprises at least a body portion and a collar portion, one or more of which are configured to be coupled to a cutting instrument, such as a drill bit, in a specified location and manner to prevent unwanted movement. In embodiments, the assembly of the body and collar portions may be incrementally adjusted to alter the desired depth of the cutting instrument. Methods for using the foregoing apparatus are also disclosed herein.

Methods and systems for providing treatment planning information for a neurology procedure, including neurosurgical procedures. A database containing historical data about historical procedures is accessed. Historical data relevant to a neurology procedure is determined, based on a determination of similarity to a set of data characterizing the neurology procedure. Historical instances of procedure parameters relevant to the neurology procedure are determined and displayed.

An OCT (Optical Coherence Tomography) handheld device is provided comprising: a housing configured for handheld OCT scanning during a surgical procedure, the housing comprising an OCT scanning end and a proximal end opposite the OCT scanning end; an OCT scanning device inside the housing, the OCT scanning device configured for one or more of OCT polarized scanning and Doppler OCT scanning from the OCT scanning end, the OCT scanning device further configured to receive and convey OCT light between the proximal end and an OCT analysing system; and a tip extending from the OCT scanning end, the tip being removably attached to the OCT scanning end, the tip configured to receive and collect the OCT light therethrough. The OCT handheld device is configured to be removably draped around the tip, for use in the surgical procedure.

Disclosed is a brain implant placement apparatus, which includes a base member contoured to rest against a cranium of a patient. The brain implant apparatus including a pivot arm hingedly coupled to the base member and configured to rotate from a first configuration to a second configuration. The brain implant placement apparatus including an implant attachment member coupled to the pivot arm via a rotating attachment mechanism and further comprising a receiving portion configured to removably couple with a brain implant and rotate the brain implant. In the first configuration, the pivot arm is positioned such that the receiving portion of the implant attachment member is facing upward. In the second configuration, the pivot arm is positioned such that the receiving portion of the implant attachment member is facing substantially downwards.

A surgical access assembly and method of use is disclosed. The surgical access assembly comprises an outer sheath and an obturator. The outer sheath and obturator are configured to be delivered to an area of interest within the brain. Either the outer sheath or the obturator may be configured to operate with a navigational system to track the location of either within the brain. Once positioned at a desired location, the obturator is removed, leaving a distal end of the outer sheath adjacent an area of interest, and creating a working corridor. Interrogation of the area of interest may be performed to evaluate a disorder and/or abnormality, as well as evaluate treatment regimes. Interventional devices may also be introduced to the area of interest, as well as a variety of treatments.

The navigation systems and methods facilitate aligning a tool in relation to a trajectory in real-time to receive input data from a pre-operative plan image, at least one multi-modal image, and at least one real-time multi-modal image; interactively track at least one neural fiber, whereby interactively tracked fiber data is obtainable; automatically generate output data by way of data transformation using the input data and the interactively tracked neural fiber data; and transmit the output data to at least one of: at least one display device for rendering at least one real-time interactive navigation display for facilitating neural navigation, and at least one drive device for positioning at least one tracking device in relation to the tool in real-time, whereby real-time alignment data is achievable, and whereby at least one neurological structure is preservable.

Disclosed is a guide or alignment system. The system may be used to at least assist in a procedure. The system may assist in aligning objects and/or determining physical boundaries for a selected portion of the procedure.

In an illustrative embodiment, an adjustable cradle assembly for adjusting a head position of a patient relative to a patient platform includes a base portion with a pair of vertical support members and a cradle portion. The vertical support members may each include at least one position aperture for setting a vertical height of the cradle portion relative to the base portion. The cradle portion may include a channel for receiving a head fixation ring. The cradle portion may include at least one set of adjustment connection points for aligning with position apertures of each vertical support member. The cradle may be pivotably connected to the vertical support members such that a pitch angle of a head position of a patient secured in the head fixation apparatus may be adjusted. A set of adjustment mechanisms may releasably secure the cradle to the base at a selected lateral and/or pitch position.
