AO AXON — Anatomical EXplorer for Optimal Navigation

Robotic navigation. Redefined for neurosurgery.

Over the last three decades, Alpha Omega has relentlessly pursued innovation, propelling us to the forefront of biomedical robotic technology.

AO AXON, our latest neurosurgical robot, has elevated the standards of robotic assistance in neurosurgery. Through combining our world-class light registration technology and an advanced surgical planning suite, we provide neurosurgeons with a remarkably accurate, unparalleled surgical experience.

Clinical Applications

Through substantial technical expertise, a wealth of clinical experience, and collaborative efforts with medical professionals, AO AXON excels in procedures treating a wide variety of diseases. Our robot's open platform facilitates future expansion, ensuring its adaptability to evolving clinical needs.

  • Deep Brain Stimulation (DBS) — Precise and stable surgical platform allowing for real-time verification and fine-tuning of surgical paths, facilitating the accuracy of electrode implantation within 0.5mm.*
  • Stereoelectroencephalography (SEEG) — Optimizes electrode implantation efficiency. Combined with vascular avoidance technology, minimizes the risk of intracranial hemorrhage during implantation.
  • Stereotactic Biopsy — Precise biopsy of tiny lesions, without restriction on age or patient position. Rapid scan and registration combined with vascular avoidance technology helps surgeons effectively reduce the risk of intracranial hemorrhage and infection.
  • Cerebral Hemorrhage / Drainage — One-click hematoma contouring, lesion volume calculation, 3D structured light registration, and robotic arm guided positioning. Fast, accurate and minimally invasive surgical procedures can bid farewell to the era of "blind punctures."

3D Structured Light Registration Technology
In robot-assisted neurosurgery, patient registration is pivotal for the entire surgical process. The main role of this process is to map out the surgical path from virtual plans into reality. The accuracy of patient registration dictates the accuracy of the final navigation; positioning of the robot and its efficiency impact overall operation time.

Markerless Registration
No preoperative markers or registration CT scanning needed. Our 3D structured light technology is designed for contact-free registration in under 2 minutes, which is 5 to 10 times faster than that of marker registration.*

Comprehensive Head Scan, No Limits
Our 3D structured light technology captures detailed point cloud data of the patient's head and face from almost all angles. It obtains over 3 million points of point cloud data, facilitating rapid marker-free registration from any position.

Registration Accuracy of 0.5mm
Our 3D structured light technology can achieve a registration positioning accuracy of less than 0.5mm, surpassing laser registration by 300 times due to the large amount of point cloud data we can obtain.*

3D Structured Light Localization
No markers or manual assistance required during patient registration. AXON's robotic arm is designed for achieving precise localization of the entire brain, easily adapting to the needs of different surgical methods and positions while eliminating light path occlusion and placement problems.

High Tech Vision Obstacle Avoidance
Through the combination of data from the 3D structured light registration and preoperative CT scans, our robot acquires and establishes the patient's head and surrounding environment into an obstacle model. This allows the robotic arm to calculate the optimal obstacle avoidance path for safe and efficient positioning.

Safe and Efficient Robotic Arm
The robotic arm is a core component of any surgical robot, and neurosurgery demands peak performance from this crucial point. Alpha Omega commits to always upholding strict standards regarding safety, developing products that support safer and more accurate robotic surgeries for both doctors and patients alike.

Six-Dimensional Force Sensor
Real-time monitoring of force exerted on the robotic arm is ensured by six-dimensional force sensors. Instantaneous braking occurs if the abnormal stress exceeds 1N, with a reaction time under 30 milliseconds, prioritizing the intraoperative safety of both doctors and patients.

Power Off Emergency Stop, Static Lock
Our robot employs an advanced lock-brake system. In emergencies or power failures, the robotic arm can lock instantaneously, stabilizing the end effector of the arm like a rock, providing doctors with a greater sense of stability.

Integrated Surgical Planning Suite

The surgical planning system is the soul of any intelligent surgical robot. The robotic system comes equipped with a surgical planning system tailored to the clinical needs of specialists, enabling comprehensive, accurate, and fast planning, coupled with simulated execution.

Modern 3D Reconstruction
The surgical planning software accomplishes 3D modeling and simulated resection of skin, skull, blood vessels, brain parenchyma, focal tissue, and more. Doctors benefit from multi-modal image display when making critical surgical decisions.

Vascular Reconstruction, Clear View
3D vascular depiction technology offers a clear and intuitive multidimensional view of the patient's intracranial blood vessels. Doctors can visualize trajectories through complex vascular structures and minimize the risk of intracranial hemorrhage during surgery.

Multitude of Surgical Planning Functions
The system combines professionalism and ease-of-use, tailored to the needs of each procedure. Supporting DBS, SEEG, Hematoma, and Biopsy workflows.
