Axis Surgical's EC-MOR facilitated real-time visualization of anterior spine column during surgery

Axis Surgical Technologies, Inc., reports the first evaluation of the C-MOR™ Visualization Device in a spine procedure. The C-MOR™ is a self-contained portable direct-imaging tool that functions much like a standard arthroscopic tower, yet at a fraction of both the size and cost. The handheld lightweight device offers practitioners the convenience of intraoperative visualization and complete operability in one hand. The C-MOR™ comprises a distinctive and cost-effective imaging device offering benefits to medical practitioners in a variety of applications, including lengthy surgeries requiring constant re-evaluation of the operating field over the course of the surgery.
