O-arm™
Surgical imaging system
For Spine, Orthopaedic Trauma, and Neurological Procedures
The O-arm™ system is an intraoperative 2D/3D imaging system that is designed to meet the workflow demands of the surgical environment. It can be used in variety of procedures including spine, cranial, and orthopedics.
O-arm™ is part of the AiBLE™ solution
O-arm™ Surgical Imaging System is a foundational component of AiBLE™, Medtronic's digital data-driven surgery ecosystem.
AiBLE™ is an integrated experience of innovative technology, software, services and people that aims to Connect, Predict and Advance.
O-arm™ 4.3 software - now available in India
Medtronic surgical imaging has reached new levels.
Introducing 3 new functional enhancements: 3D Long Scan, Spine Smart Dose and Medtronic Implant Resolution.
3D Long Scan (3DLS), with robotic gantry movement, now allows 3D imaging up to 43.8cm, adding visibility to additional levels of the patients spinal anatomy.8
The Spine Smart Dose (SSD), an AI based algorithm, only needs 70% of the dose of a standard scan, while maintaining the image quality.8
Standard Dose
Spine Smart Dose
To support surgeons in making a confident clinical decision, the new Medtronic Implant Resolution (MIR) functionality aids. It helps with evaluation of the screw placement by enhancing the visualization of the bone anatomy around certain Medtronic screw systems.8
Indications
The O-arm™ O2 Imaging System is a mobile x-ray system designed for 2D fluoroscopic and 3D imaging for adult and pediatric patients weighing 27kg or greater and having an abdominal thickness greater than 16cm, and is intended to be used where a physician benefits from 2D and 3D information of anatomic structures and objects with high x-ray attenuation such as bony anatomy and metallic objects. The O-arm™ O2 Imaging System is compatible with certain image guided surgery systems.
Product details
The O-arm™ system’s high quality, versatile imaging provides the information you need to guide your clinical decision making.
Advanced energy solutions
Along with StealthStation navigation, the O-arm™ system provides enhanced 3D visibility and surgical feedback. It also:
- Provides current patient data in the OR
- Enables advanced surgical approaches like MIS
- Provides additional information in challenging procedures, like heavier patients or patients with unusual anatomy1,2,3
- Automatic registration keeps the process simple
The O-arm™ system also offers options for workflow efficiencies, such as:
- In procedures where pre-op axial/coronal/sagittal slice data is necessary, it may be possible to use the O-arm™ system to provide the initial data set
- Eliminating the need to send patients to be scanned in radiology
Imaging protocols
The O-arm™ system provides flexibility for surgeons to achieve As Low As Reasonably Achievable (ALARA). Multiple image protocols allow the surgeon flexibility to choose the appropriate dose to the patient based upon individual clinical objectives.4
Opportunities to reduce dose
With opportunities to reduce dose to the surgeon and staff, the O-arm™ and StealthStation systems eliminate the need to wear lead protective apparel during the navigated steps of the procedure.5,6
Surgical workflow
The O-arm™ system has been designed to complement the surgical workflow with:
- Multiple surgical table options
- Inter-room mobility for concurrent cases
- On-demand imaging, no need to schedule in advance
