Neuro Arm Microsurgery Robot from the University of Calgary.

The Neuro Arm Robot is the world's first Magnetic Resonance Imaging compatible surgical robot and was developed by Dr. Garnett Sutherland and his team of Canadian scientists during the last six years in the University of Calgary, with the cooperation of MacDonald, Dettwiler & Associates. MDA is known for building the International Space Station robotic arms, Canadarm and Canadarm 2. Sutherland team made medical history at the Calgary Foothills Hospital by removing a tumor from a woman´s brain using the robot coupled with an MRI scanner for viewing the procedure.
The robot is designed to be controlled by a surgeon from a computer workstation and operates in conjunction with a real-time MRI imaging scanner. The arm’s motion is controlled by small piezo-ceramic motors that don’t interfere with the magnetic field of the imaging device. The Neuro Arm provides surgeons with incredible detail and control to manipulate tools at a microscopic scale, enhancing the spatial resolution at which they operate.
It has the advantage to move in small increments; the human hand can steady itself and move in increments of 1 or 2 millimeters, Neuro Arm can move in increments of 50 microns and is less invasive inside the brain by moving with more care than the surgeon’s hand.
Doctors use the remote controls and the imaging screen much like in a video game to guide the two-armed robot through the patient brain. The surgical instruments operate as the hands of the Neuro Arm. The brain surgery made to the first patient represented a technical achievement in the use of image-guided robotic technology to remove a relatively complex brain tumor and allowed the high field MRI scanner to move into the operating room for surgical procedure on demand.

The neuro arm provide a new degree of freedom of surgeons
1. Neuro Arm came from the need to have precise instruments in Neurosurgery
2. Neuro Arm works within a MRI machine
3. Neuro Arm provides Haptic feedback input for the Surgeon
4. The Neuro Arm is made of special plastics called Peak and Titanium. MDA was the company selected to build the robot system.
5. The robot system provides a 3D image of the tools position in the patient. The surgeon uses a 3D volume set and field cameras of the operative site.
6. Hand controls provide seven degrees of freedom and create a sense of touch and accuracy. The system is accurate to 2-3 microns.
7. Robotics are the future.
8. Neuro arm provides playback increasing the effectiveness of very complicated procedures.
What spacial virtual reality capablites exist in the system and how does haptic feedback enhance the success of the operation?
What level of dexterity did the robot provide the neurosurgeon that was not possible manually?
