Telerobotic surgery using the Robot-Assisted MicroSurgery (RAMS) system shows feasibility for vessel manipulation. Further development is needed to enhance its application in complex microsurgical procedures.

Area of Science:

  • Robotics in Medicine
  • Microsurgery
  • Surgical Technology

Background:

  • Telerobotic surgery offers potential for enhanced surgeon dexterity and improved microsurgical outcomes.
  • Novel microdexterity enhancement systems are being developed to advance surgical capabilities.

Purpose of the Study:

  • To evaluate the feasibility and performance of a prototype Robot-Assisted MicroSurgery (RAMS) system.
  • To compare telerobotic surgery with conventional microsurgical techniques in a preclinical model.

Main Methods:

  • A prototype RAMS system was tested on 10 rats undergoing carotid arteriotomy creation and closure.
  • Procedures were compared based on time, technical quality (vessel patency, suture integrity), error rate, and subjective difficulty.

Main Results:

  • The RAMS system successfully manipulated vessels but not needles or sutures.
  • Telerobotic surgery demonstrated comparable precision, technical quality, and error rates to conventional methods.
  • The RAMS system use resulted in a twofold increase in procedure length.

Conclusions:

  • The prototype RAMS system is feasible for surgical applications, particularly vessel manipulation.
  • Future iterations incorporating stereotelevisualization and haptic feedback could enable telerobotic neurosurgery.
  • Further development is essential to optimize telerobotic systems for broader surgical use.
