What is the O-ARM 2 scanner?

O-ARM 2 device is an intraoperative surgical navigation system that, by taking scanned images, allows surgeons to visualize the patient's anatomy in the surgical position, pinpoint the precise location for the implants in the spine and monitor the status of the surgery at all times.

Instituto Clavel began using the O-ARM 2 scanner in 2015, making us the first to use this imaging system in Spain. Thanks to this system, which allows us to work with an extremely high degree of precision, the surgery is less invasive, takes less time, and is more effective.

 

What are the benefits for the patient?

The intraoperative scanner has been a great advance for minimally invasive surgeries, and increases their effectiveness. The primary benefits to the patient of using this technology during the surgery are: 

1

The O-arm® 2 scanner reduces patient trauma in comparison with open surgical intervention, which is associated with a greater degree of muscle trauma and comorbidity.

2

It allows minimally invasive techniques to treat spinal pathologies such as degenerative diseases, injury, spinal tumors and deformities, such as scoliosis, which have not been able to benefit from such techniques until now.

3

This navigation system guarantees the most precise image quality during the surgery to achieve the best outcome for the patient.

4

Provides superior real-time visualization of the patient’s anatomy, which facilitates greater precision in the placement of the implants and a significant improvement in the patient’s safety.

5

Shows 3D imaging of the finished surgery prior to closure, giving the opportunity to confirm the correct placement of the implants, which reduces the likelihood of needing later corrective surgery and other complications.

6

Unlike traditional intraoperative systems, all movements are robotic, and are controlled by a simple dashboard.

7

The motorized system makes it possible to easily move the device from one operating room to another, while still providing the reliability of image quality at the level of a fixed installed diagnostic CT.

8

The motorized re-positioning reduces the need for manual movements and the need to take additional images.

How does it work?

Intraoperative image-guided surgery facilitates the surgical workflow by providing the surgical team with real-time radiological images of the patient. This is how it works:

  • The scanner is placed over the patient and the images are taken.

  • The software converts the specific images of the patient taken before the surgery to a data set and shows them on a monitor as seen from various perspectives: axial, sagittal, coronal, surgical trajectory, and “probe’s eye” view.

The surgeon can use the scanner both before and during the operation:

  • Prior to the operation, it can be used to create, store, and simulate progress along one or more surgical trajectories. As an imaging tool it can also be used to create and manipulate one or more 3D models automatically, either contoured or manual, of the patient’s anatomy (skin, cortex, tumors, blood vessels, skull…), and the surgeon can visualize the form in 2D imaging from various perspectives.

  • During the operation, the arm system provides surgical imaging of the position of all the instruments that are used to place the implants in, or on, the patient’s anatomy, continuously updating its location, providing real-time dynamic imaging.
