Robotic Surgery

  • “Robot-assisted surgery was developed to overcome limitations of minimally invasive surgery, Instead of directly moving the instruments the surgeon uses a computer console to manipulate the instruments attached to multiple robot arms. The computer translates the surgeon’s movements, which are then carried out on the patient by the robot.”

Robotic surgical simulator l.jpg
Robotic Surgical Simulator

  • Stand-alone surgical simulator

  • No consumables or disposables required

  • Allows performance analysis and measurement

  • User does not require monitoring

  • New surgical procedure modules can be added

  • Does not require an operating room environment and can be set up in a location most advantageous to access and training needs

  • Monitor allows a user or tutor to observe the procedure

  • Comprehensive curriculum to train for motor, and cognitive skills
