Area of Science:

  • Surgical robotics
  • Medical engineering
  • Human-machine interface

Background:

  • The human hand-arm system has seven degrees of freedom for object manipulation.
  • Open surgery utilizes all seven degrees of freedom for surgical instruments.
  • Endoscopic procedures are limited to four degrees of freedom due to trocar insertion, reducing instrument functionality.

Purpose of the Study:

  • To investigate the use of robotics and telemanipulator technology to restore full spatial mobility for endoscopic instruments.
  • To develop and experimentally evaluate a functional model of an endoscopic master-slave manipulator system.

Main Methods:

  • Development of a functional model for an endoscopic master-slave manipulator system.
  • Experimental surgical evaluation of the developed system.

Related Experiment Videos

  • Investigation of allied technologies such as tactile sensors and vision systems.

    • Main Results:

    • A functional model of an endoscopic master-slave manipulator system has been created.
    • The system is currently undergoing experimental surgical evaluation.
    • New tactile sensor and vision systems are being explored to enhance robotic surgery applications.

    Conclusions:

    • Robotic and telemanipulator technology can effectively restore the lost degrees of freedom in endoscopic surgery.
    • The developed master-slave manipulator system shows promise for enhancing instrumental functionality in minimally invasive procedures.
    • Advancements in sensor and vision technology will further improve the application of robotic systems in future surgeries.
