Cirq® is a lightweight, versatile and modular robotic surgical system designed to assist surgeons precisely when and where support is needed. Cirq can be used for safe and effective sEEG electrode placement 1 for epilepsy. The sEEG workflow is based on clinically proven optical navigation that enables surgeons to monitor accuracy and increase efficiency.

Cirq in a functional neurosurgery workflow
Streamlining epilepsy workflows through collaborative robotics
Brainlab assists surgeons with the alignment and placement of sEEG electrodes by offering solutions with advanced planning features, accurate registration options and real-time optical tracking. When these solutions are combined with Cirq, users can benefit from steady, unified and uninterrupted support.
For example, surgeons can first manually align the Cirq Arm System in the vicinity of the patient’s head and then use the Cirq Robotic Alignment Module to automatically align to the preplanned trajectory. This also removes the need to fixate the patient to a frame before the surgery, thereby increasing patient comfort.
Accuracy and stability through tracking and navigation
The real-time tracking of instruments with deviation monitoring enables accurate bone anchor placement while the sEEG Drill Kit minimizes movement during the procedure and enables controlled drilling through the Alignment Guide Tube. Advanced Alignment Software Cranial features also allow for assisted skull thickness measurement for each trajectory.
In addition, by using the buttons on the Cirq Robotic Alignment Module, the navigation system can be controlled from the sterile field O.R. without screen interaction. The pointer measurement feature also uses information from the navigation system to automatically measure the required length of the electrodes.

Interchange modules for more flexibility
The future of robotic surgery is modular. With its interchangeable modules, Cirq is a highly adaptable and versatile robotic surgical system.
Kinematic Unit
Precisely translates motor movement of Cirq Robotic Alignment Module with zero mechanical backlash
Cirq Robotic Alignment Module
Application specific, interchangeable module that enables precise robotic alignment to preplanned trajectories
Tracking array
Highly accurate tracking array with locking mechanisms for rotational and longitudinal movement of guide tube
Alignment Guide Tube Cranial
Guides the Drill Bit, Bone Anchor and Screwdriver while securing the entry point by docking the tip on the patient’s skull
Drill Bit Cranial
Optimized design with centering tip to reduce skiving effects. Balanced depth control securely stops Drill Bit at a set distance
High clearance between robot and skull
After implantation, sEEG anchor bolts are quite fragile and may protrude from the patient’s skull. As a result, any collision with the anchor bolts must be avoided.
During manual pre-alignment, the Cirq Alignment Software Cranial accounts for the height of the anchor bolts. This results in a high clearance between the skull, implanted sEEG anchor bolts and the Cirq Robotic Alignment Module.
Modify anchor bolts and trajectories with ease
Surgical plans including anchor bolt placements and trajectories may need to change due to unforeseen circumstances in the O.R.
When necessary, the entry point of the anchor bolt or trajectory can be easily modified with the navigation pointer. The updated trajectory can then be reviewed and integrated into a seamless intraoperative workflow.
Effortlessly integrate Cirq into unique workflows
When it comes to highly accurate registration workflows, Alignment Software Cranial is agnostic and can effortlessly integrate into other workflows such as Automatic Image Registration and landmark registration.
