Hands-free interface for surgical procedures based on foot movement patterns.

Area of Science:

• Robotics
• Surgical Technology
• Human-Computer Interaction

Background:

• Minimally invasive surgery requires precise instrument control.
• Current methods often rely on hand-held controls, limiting surgeon dexterity.
• Developing hands-free control interfaces can improve surgical efficiency.

Purpose of the Study:

• To develop and evaluate a novel hands-free interface for controlling a robotic surgical system.
• To enable a single surgeon to operate a forceps manipulating robot using foot-based input.

Main Methods:

• A pressure sensor sheet was used to measure foot pressure and center of gravity shifts.
• Pattern recognition algorithms analyzed six distinct foot movements performed by surgeons and students.
• A five-degrees-of-freedom robotic control interface was developed based on specialist foot movement patterns.

Main Results:

• The system successfully distinguished between different foot movements.
• The developed interface allowed for effective control of a robotic manipulator.
• The robot demonstrated successful manipulation of a model organ during simulated surgery.

Conclusions:

• A hands-free, foot-controlled interface is feasible for robotic surgery.
• This technology has the potential to enhance surgeon control and dexterity.
• Further development could lead to improved outcomes in minimally invasive procedures.
