Area of Science:

  • Medical Education Technology
  • Surgical Simulation
  • Augmented Reality Applications

Background:

  • Suturing proficiency requires consistent practice and expert guidance, which is often limited.
  • Augmented reality (AR) shows promise in aiding procedural skill development for learners.
  • This study investigates an AR application for independent suturing practice.

Purpose of the Study:

  • To evaluate the effectiveness of a novel AR suture guidance application.
  • To assess AR's impact on medical students' independent suturing practice and skill acquisition.
  • To gather user feedback on the AR application's usability and limitations.

Main Methods:

  • A Microsoft HoloLens-based AR application with holographic step-by-step guidance was developed.
  • 30 medical students were randomized into a control (independent practice) and experimental (AR guidance) group.
  • Both groups underwent pre- and post-test wound closure assessments; statistical analysis used t-tests.

Main Results:

  • Both groups improved in overall time and time per stitch.
  • The AR group showed significant improvements in total stitches, bisecting stitch ratio, and stitch bite symmetry.
  • User feedback indicated the AR application effectively guided suture placement and spacing, with suggestions for hologram stability.

Conclusions:

  • Augmented reality holds potential for facilitating independent suturing practice in simulated environments.
  • AR guidance can enhance specific metrics of suturing technique, such as stitch accuracy and symmetry.
  • Further development is needed to address user-identified limitations for optimal AR surgical training.
