The Dynamis Robotic Surgical System is an integrated navigation-based robotic platform with real-time tracking capability for spine surgical procedures that include cervical, thoracic, lumbar, and sacral approaches. The system is comprised of two computer-controlled robotic arms to support surgical robotic guidance, while a third robotic arm holds and controls the Scout navigation camera. All components are integrated into one physical cart located partially underneath the surgical table. The cart employs bilateral elevator mechanisms to deploy and fold the surgical robotic arms and secure them. This system functions in conjunction with different intraoperative imaging systems by data transfer of DICOM format images by USB and/or Direct LAN transfer for intraoperative planning. The system software is responsible for all motion control, navigation, data storage, user management, case management, and safety functions. The system establishes registration between the virtual patient (points on the patient DICOM images) and the physical patient (corresponding to the patient’s anatomy). The information of the plan, coupled with the registration, provides the necessary information to give visual assistance to the surgeon during the robotic alignment of qualified instruments or during free-hand navigation. Qualified instruments that are rigid, straight, round, and concentric are permitted for use through the Dynacan or used with the Dynatracker, given they pass the Instrument Setup process. The system also supports individual vertebra tracking to maintain alignment to vertebra specific trajectories by monitoring relative vertebral motion, as well as a stabilization workflow which provides additional control of vertebral motion during instrumentation.
An assembly of electromechanical devices designed to be used during computer assisted surgery (CAS) as a functional extension of the surgeon for precise procedural movement and placement (navigation) during the procedure (e.g., placement of a pedicle screw in spinal surgery). It typically consists of an operator's console featuring a robotic surgical arm(s) and a video camera used to track the robotic instrumentation. The input to the computer is usually by means of an existing CT or MRI scan. The system tracks the instrumentation by reading the location points giving a three-dimensional (3-D) picture of the instrument's position/angulation. It can also be used as a training aid.
