Intended Use

The device is intended for the spatial positioning and orientation of instrument holders or tool guides to be used by neurosurgeons to guide standard neurosurgical instruments (biopsy needle, stimulation or recording electrode, endoscope). The device is indicated for any neurosurgical procedure in which the use of stereotactic surgery may be appropriate.

Device Story

ROSA Brain is a robotized, image-guided platform for neurosurgical instrument positioning. Input: preoperative MRI/CT images. Surgeon performs surgical planning (target/entry points, instrument length) using ROSANNA BRAIN 3.0 software. During surgery, the device uses a 6-axis robotic arm to provide rigid, accurate mechanical guidance for instruments (biopsy needles, electrodes, endoscopes) based on the plan. The system includes a touch screen for user communication and commands. The device is used in the neurosurgical operating room by neurosurgeons. It provides real-time visualization of instrument position relative to preoperative images, ensuring reproducible guidance. Benefits include increased accuracy and stability in stereotactic procedures.

Clinical Evidence

No clinical data or animal studies were provided. Substantial equivalence is supported by bench testing, including biocompatibility (ISO 10993), electrical safety (IEC 60601-1), electromagnetic compatibility (IEC 60601-1-2), and comprehensive software verification and validation.

Technological Characteristics

6-axis electromechanical robotic arm; mobile stand with 4 stabilization feet; touch screen interface; 1-pedal footswitch. Integrates with preoperative 3D MRI/CT (DICOM 3.0). Registration via fiducial markers, optical laser telemeter (Class 2), or stereotactic frame. Software: ROSANNA BRAIN 3.0. Sterilization: Not specified (standard surgical instrument guidance).

Indications for Use

Indicated for neurosurgical procedures where stereotactic surgery is appropriate, including biopsy, stimulation/recording electrode placement, and endoscopy. For use by neurosurgeons.

Regulatory Classification

Identification

A stereotaxic instrument is a device consisting of a rigid frame with a calibrated guide mechanism for precisely positioning probes or other devices within a patient's brain, spinal cord, or other part of the nervous system.

The touch screen ensures the communication between the device and its user by indicating the actions to be done as well as by offering various commands.

ROSA Brain is an image-quided device that assists the surgeon in planning the position of instruments or implants on preoperative or intraoperative images. It provides a stable, accurate and reproducible mechanical guidance in accordance with the planning.

An image acquisition of the patient's head (MRI / CT images) is performed prior to surgery and loaded into the device.

In the preoperative phase, the surgeon carries out the surgical planning on the patient images using the device software. The desired surgical parameters for positioning of the surgical instruments are defined (for example: target point, entry point and instrument length).

During surgery, the device provides accurate and rigid quidance of the required instrument according to the previously completed planning.

#### > INDICATIONS FOR USE
