Summary

Surgical manipulator systems can enhance patient safety in middle ear surgery by improving precision and reducing surgeon fatigue. Further development should focus on compact systems compatible with standard instruments for wider clinical adoption.

Area of Science:

  • Otolaryngology
  • Medical Robotics

Background:

  • Middle ear surgery presents significant risks due to delicate, hard-to-differentiate structures, necessitating precise surgical techniques.
  • Human factors like tremor and environmental limitations (e.g., operating room setup, narrow access) pose challenges in middle ear procedures.

Purpose of the Study:

  • To review existing surgical manipulator systems for middle ear surgery.
  • To identify potential improvements for enhanced patient safety, surgical accuracy, and ergonomic benefits.

Main Methods:

  • Review of current literature and existing surgical manipulator technologies.
  • Analysis of clinical applications, including modified industrial robots and various master-slave systems.

Main Results:

Published on: May 23, 2021

  • Surgical manipulators offer the potential to compensate for human and systematic limitations in middle ear surgery.
  • Existing systems include modified industrial robots and master-slave configurations, with some located directly at the patient.

Conclusions:

  • Current manipulator systems often have limited instrument compatibility, requiring specialized tools.
  • Future development should prioritize compact, short-distance operated master-slave systems that integrate standard instruments to improve acceptance and usability.
  • The surgeon remains central, requiring ergonomic support and retaining responsibility; highly automated systems are not the primary research objective.
