Researchers at EPFL, a public analysis college in Lausanne, Switzerland, have developed a robotic system that permits surgeons to carry out laparoscopic surgical procedures with 4 arms by controlling two robotic arms utilizing haptic foot interfaces. The outcomes had been printed in The Worldwide Journal of Robotics Analysis.

The analysis was a collaboration between the analysis group REHAssist and the Studying Algorithms and Techniques Laboratory (LASA). It was led by EPFL Ph.D. college students Jacob Hernandez and Walid Amanhoud, who developed a system that permits surgeons to manage two robotic arms utilizing haptic foot interfaces with 5 levels of freedom. On this setup, every of the surgeon’s arms controls a manipulative instrument, whereas one foot controls an actuated gripper whereas the opposite controls an endoscope or digital camera. 

“Actuators within the foot pedals give haptic suggestions to the person, guiding the foot in the direction of the goal as if following an invisible field-of-forces, and likewise restrict power and motion to make sure that faulty ft actions don’t endanger the affected person,” Mohamed Bouri, head of REHAssist, stated. “Our system opens up new potentialities for surgeons to carry out 4-handed laparoscopic procedures, permitting a single particular person to do a job that’s normally carried out by two, generally three individuals.”

One key facet of the system is that management is shared between the surgeon and robotic assistants. The researchers designed a management framework that ensures the surgeon and robots can work collaboratively inside a concurrent workspace whereas nonetheless assembly the precision and calls for of laparoscopic surgical procedure. 

This characteristic helps to reduce fatigue for surgeons, because the robots can generally lead the surgeon’s management of an instrument because it predicts the place the surgeon desires to maneuver. 

“Controlling 4 arms concurrently, furthermore with one’s ft, is much from routine and will be fairly tiring. To cut back the complexity of the management, the robots actively help the surgeon by coordinating their actions with the surgeons via lively prediction of the surgeon’s intent and adaptive visible monitoring of laparoscopic devices with the digital camera. Moreover, help is obtainable for extra correct greedy of the tissues,” Professor Aude Billard, head of LASA, stated. 

Specialists have already been educated on the system and medical trials are at present ongoing in Geneva. The analysis staff carried out a complete person examine with training surgeons. 

In response to Dr. Enrico Broennimann, who has participated within the trials in collaboration with the Swiss Basis for Innovation and Coaching in Surgical procedure (SFITS), “The concept to actively use one’s ft to carry out robotic-assisted surgical procedure is a good suggestion, and it’s undoubtedly a learnable talent. I’d prefer to see it carried out within the working room, maybe as a cockpit effectively away from the affected person to extend ergonomics.”
