The SYMBIS Surgical System is a computer-controlled electromechanical arm. The arm is performed by the neurosurgeon. It is intended to be used in the spatial positioning and orientation of a biopsy instrument guide.

Guidance is based on a pre-operative plan developed using the Medtronic StealthStation® along with fiducial marker or optical registration. The system is intended for use by neurosurgeons to guide a biopsy needle.

It is intended for use by trained physicians for needle based biopsy.

The SYMBIS Surgical System is a computer-controlled electromechanical arm. It is intended to be used in the operating room for the spatial positioning and orientation of an instrument guide. The system is intended for use by trained physicians for needle based biopsy.

The SYMBIS Surgical System consists of the a Surgeon Console, Surgical Cart, Manipulator, Robot Control Cabinet (RCC), Vision System, Platform Room Integration Kit and System Software.

The Manipulator is a master/slave robot configured with either a left arm or a right arm is mounted to the Surgical Cart. The Surgical Cart is used to transport the Manipulator to and from the operating room, as well as serve as a stationary platform for robotic surgery. The Surgical Cart has an onboard immobilization system to prevent horizontal movement when positioned for surgery. The Instrument Guide is attached to the draped Manipulator and is used by the surgeon to guide the trajectory of a stereotactic instrument (e.g. Biopsy Needle). The Manipulator has six (6) degrees of freedom (DOF). The SYMBIS System provides tremor filtering and motion scaling while the surgeon positions the Manipulator and Instrument Guide to the target position. A Vision System mounted to the Surgical Cart provides the surgeon with a high definition, three-dimensional view of the patient, surgical site, and Manipulator.

The Surgeon Console provides the surgeon with workstation console from which the surgeon controls the Manipulator. The Surgeon Console is located in the operating room. The surgeon, seated at the Surgeon Console, controls all movements of the Manipulator with a hand controller and foot pedal. The upper and middle displays on the Surgeon Console are medical grade, high definition monitors, and the middle monitor is capable of displaying 3 dimensional (3D) images The upper display provides the video output from a third-party navigation system (i.e. Medtronic Stealth station s7/i7). The middle display provides the 3D video output from the field camera, to provide situational awareness to the surgeon when moving the robot near the patient, surgical site, and OR staff. The video from the Vision System, along with the video from the third-party navigation system, is used by the surgeon to manipulate the Instrument Guide to the entry position.

The Robot Control Cabinet (RCC) is an electronics rack and contains to operate the Surgical Cart, Manipulator and Surgeon Console. It is situated in the hospital's equipment room, adjacent to the surgical suite. The RCC includes the supporting electronic, power supply, and computers for the system.

The platform room integration kit includes motor drivers to run the Manipulator, an OR Pendant with an E-Stop, cable interface mounting plates and system integration cables.
