ROBOT SURGICAL PLATFORM FOR CRANIAL SURGERY
A cranial surgery planning system including at least one network interface connectable to obtain radiological patient images generated by a radiological image scanner, a display device, at least one processor, and at least one memory storing program code that is executed by the at least one processor. The operations include obtaining through the at least one network interface a first radiological patient image of cranial structure of a patient along a first plane and obtain a second radiological patient image of the cranial structure of the patient along a second plane that is angularly offset to the first plane. Operations also include merging the first and second radiological patient images to an image coordinate system. Operations also include obtaining a surgical trajectory plan defining an entry point on the patient's skull and a target point in the patient's brain captured in the merged first and second radiological patient images.
SYSTEM FOR NEURONAVIGATION REGISTRATION AND ROBOTIC TRAJECTORY GUIDANCE, ROBOTIC SURGERY, AND RELATED METHODS AND DEVICES
A system for robotic surgery makes use of an end-effector which has been configured so that a drill connected thereto is guided in its trajectory and limited in its advancement into an associated anatomical feature by a drill guide. The drill guide may be adjusted manually to engage a corresponding surface of the drill after its advancement by a pre-selected amount. The drill guide likewise includes features to guide the drill during trajectories having oblique angles relative to the surface of the anatomical feature associated with the medical procedure.

Drill guide fixtures, cranial insertion fixtures, and related methods and robotic systems
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.
SYSTEMS AND METHODS FOR A STEREOTACTIC COORDINATE ADJUSTER
Various embodiments of a stereotactic coordinate adjuster system and associated method for positional adjustment of components of a stereotactic system are disclosed herein. The system provides fine adjustment to the stereotactic system by providing form-fitting components that encapsulate components of the stereotactic system and allow for fine positional adjustment of an arc support member and a slide portion of the stereotactic system.
SELF-BIASING ANKLE CLAMP TIBIAL ALIGNMENT GUIDE
The self-biasing ankle clamp tibial alignment guide includes a clamp body, at least one lever arm outwardly extending from the clamp body, and an alignment rod generally upwardly extending toward a proximal end of a patient tibia and movable relative to the clamp body. A strap couples to the lever arm to exert a force thereon offset from a contact point where the clamp body pulls into engagement with a patient, thereby generating a moment about the contact point that causes the alignment rod carrying a cutting guide to bias forward into engagement with the patient.
UPPER COIL ASSEMBLY OF AN RF PROBE FOR USE IN AN MRI SYSTEM
An upper coil assembly for use with a lower RF coil assembly mounted to provide an RF probe arranged to be engaged with a head of a patient in MRI includes a plurality of coil loops arranged in a row defining a phase shift coil array with each coil loop including an independent output conductor for communicating signals to a respective preamplifier for independent amplification and each coil loop including a plurality of capacitors at spaced positions therearound. To decouple the loops each coil loop partly overlaps a next coil loop with a first decoupling capacitor shared on a common portion of each coil loop and each next coil loop. The first and third coil loops are also decoupled by using third decoupling capacitor in a connecting conductor between the first and third coil loops.
