7D Machine-vision Image Guided Surgery (MvIGS) System: All about This New Technology

The Machine-vision Image Guided Surgery (MvIGS) System is a recent and promising invention in the medical field. It is the first of its kind and the only image guidance system that uses new camera-based technology and machine vision algorithms to aid surgeons during complex surgeries. The 7D Surgical System eliminates the need for those involved in the surgical procedure to be exposed during radiation, which is a notable difference from traditional image guidance systems. This innovative technology makes image guided surgery faster, more cost-effective, more accurate, and free of radiation.  

A Safer Experience 

For past years most surgeons used 2D fluoroscopy during spine surgeries, which involves the use of x-rays to get images of internal parts. Recently though, computer-assisted spine navigation systems have become the more popular pick for spine surgeries due to advancements that have led to decreases in costs and increases in user friendliness. The Machine-vision Image Guided Surgery System is a product of this trend for it was created with the intent to make complex surgeries possible without the need of intraoperative radiation exposure. This means a safer environment and experience for the surgeon, patient, and staff present during the operation. 

A More Accurate Operation 

7D’s MvIGS system uses their Flash™ Registration and Flash™ Fix technology to provide true segmental registration in regard to the spine’s vertebrates. Even if the patient happens to change positions during the procedure, the accuracy of the images will not be affected. The image is 3D and in color, and it aligns to a CT taken before the operation. In short, the Machine-vision Image Guided Surgery System takes images that are not only more accurate, but also of better quality than its predecessors. This, of course, allows surgeons to be more precise and therefore more accurate with their work, which is a huge benefit to patients as it means the chances of them having to have another surgery to correct anything that went wrong with the original one is greatly reduced. 

Faster Registration and Faster Surgery 

One of the main selling points of this system is the fact that it takes less than 20 seconds for patient registration, which is considerably less than 30 minutes a traditional image guided surgery system would take. This significantly reduces the amount of time needed for an overall surgery. Also, because the time it takes for registration is so short, re-registration is a viable option for maintained accuracy during the procedure. This Machine-vision Image Guided Surgery System provides added information during surgery so that surgeons can always make the most informed decisions possible during operations. 

More Control During the Procedure 

This technology also allows surgeons to have more control over their work while they operate. There is a conveniently located foot pedal controlled by the surgeon that they can use for automated Flash™ Registration. Line-of-sight issues that might arise are removed thanks to the machine vision technology being embedded in the surgical light part of the equipment. The degree of control the surgeon is allowed with the Machine-vision Image Guided Surgery System lessens the surgeon’s need to rely on technical staff and other equipment. 

How it Works 

The machine vision part of this equipment creates images for analyzing and processing by using light, cameras, and certain programs. These high-quality images allow for identification and can be inspected, and by combining this technology with image guided surgery, 7D Surgical was able to create the Machine-vision Image Guided Surgery System. 

During the automated registration process, a 2D light is projected with visible light onto the anatomy, and the light pattern reflected from the surface of the anatomy is digitized and optimal points are automatically picked and matched with a pre-operative CT. 

The first step to using this system for spinal registration is to attach the bone clamp reference, which can be done quickly and easily with one hand. Then, the surgeon identifies co-localized points on the 3D surface and pre-operative CT scan. After, it is time to put the Flash™ Registration to work, which is done using the foot pedal and visible light. The following 3D color image aligns itself to the pre-operative scan. To confirm that everything is as it should be and verify the registration’s accuracy, the surgeon can touch anatomical landmarks. From there the surgeon proceeds with the image guided surgery. 

A Versatile Piece of Equipment 

This technology is designed to be able to be used for a variety of image guided surgeries, and can be used for cranial navigation. With tools and software for cranial work, neurosurgeons will have more control when they work. With 7D’s MvIGS system, cranial registration is instantaneous and contactless,  and it does away with the need for fusing MRI and CT registration images, which can be excessively time consuming at time.
