Doctors from Scotland and the United States have accomplished what is believed to be a historic stroke surgery using robotic technology.

The medical expert, working at a medical institution, performed the remote thrombectomy - the extraction of circulatory obstructions after a cerebral event - on a donated body that had been provided for research.

The surgeon was located at a medical facility in Dundee, while the body she was operating on with the machine was at another location at the research facility.

Subsequently, a neurosurgeon from the American state used the system to perform the pioneering long-distance operation from his American facility on a human body in Dundee over 6,400km away.

The medical group has called it a potential "game changer" if it gains clearance for medical treatment.

The doctors think this innovation could transform stroke care, as a slow access to professional intervention can have a major influence on the recovery prospects.

"The experience was we were seeing the first glimpse of the future," said the lead researcher.

"Where previously this was regarded as futuristic fantasy, we showed that each phase of the operation can now be performed."

The medical research center is the global training center of the World Federation for Interventional Stroke Treatment, and is the exclusive site in the Britain where surgeons can work with medical specimens with actual blood circulated in the arteries to mimic treatment on a live human.

"This represented the pioneering moment that we could conduct the entire surgical process in a genuine medical subject to prove that each stage of the operation are achievable," said the primary researcher.

Juliet Bouverie, the head of a stroke charity, called the long-distance operation as "a remarkable innovation".

"Over extended periods, individuals from isolated regions have been deprived of access to clot removal," she added.

"Robotics like this could address the disparity which occurs in stroke treatment nationwide."

What is the operational process?

An ischaemic stroke happens when an artery is blocked by a clot.

This disrupts circulation and oxygenation to the neural matter, and brain cells cease working and die.

The optimal therapy is a clot removal, where a expert uses catheters and wires to clear the obstruction.

But what occurs when a patient is unable to reach a expert who can conduct the operation?

Prof Grunwald said the trial proved a automated system could be connected to the equivalent surgical tools a doctor would normally use, and a medic who is attending the case could readily join the instruments.

The specialist, in a separate site, could then hold and move their own wires, and the mechanical device then executes precisely identical actions in immediate sequence on the subject to conduct the clot removal.

The subject would be in a treatment center, while the specialist could conduct the operation via the advanced machine from any location - even their private dwelling.

The lead researcher and the neurosurgeon could view real-time imaging of the specimen in the trials, and monitor progress in live conditions, with the lead researcher saying it took only 20 minutes of instruction.

Tech giants prominent manufacturers were involved in the initiative to secure the communication link of the automated system.

"To operate from the United States to Scotland with a 120 millisecond lag - a blink of an eye - is absolutely amazing," stated the medical expert.

Innovations in cerebral healthcare

The lead researcher, who has received recognition for her work and is also the senior official of the World Federation for Interventional Stroke Treatment, explained there were primary challenges with a conventional clot removal - a international lack of surgeons who can do it, and intervention relies upon your physical place.

In the Scottish nation, there are merely three sites people can obtain the treatment - urban centers. If you don't live there, you must travel.

"The treatment is extremely time-critical," explained the medical expert.

"For every six minutes of waiting, you have a 1% less chance of having a successful recovery.

"This innovation would now offer a new way where you're independent of where you dwell - preserving the crucial moments where your cerebral matter is degenerating."
