Abstract:
Operating room setup, patient positioning and operating port placement are essential to operative success in minimally invasive surgery (MIS). Errors in judgment and or execution of these steps increase the difficulty of performing a procedure and ultimately lead to prolonged operations, conversions to open surgery and increased surgical morbidity. Immersive virtual reality training allows residents to prepare for operative procedures in an environment that provides feedback and monitors their individual progress The ultimate goal is to decrease the impact of resident training on healthcare cost and patient morbidity.
We've developed an application that
allows residents to learn the proper operating room configuration for MIS
procedures and practice procedure specific patient alignment, surgeon position,
and port placement. The simulation
operates on a Silicon Graphics Octane workstation connected to an immersive
three dimensional projection system (ImmersaDesk). Residents are able to master these setup tasks for each of 10
common MIS procedures.
Three-dimensional models and hanging menues are included on the
ImmersaDesk. Visual and audio feedback
are given, identifying potential problems.
Resident performance data is collected on a separate computer. Elapsed time to accurately complete each
phase of the training along with the number of errors committed are
recorded.
The ImmersaDesk and other
three-dimensional displays have been shown to be very effective methods of
teaching positional skills. We believe
that this application is an excellent use of the spatial capabilities of the
ImmersaDesk. We also wish to stress
that this is just the first stage of a complete Minimally Invasive Surgery
simulation program. When we have
perfected our techniques for realistic models of organs, tissues, and
laparoscopic instruments we will include them in this application.
Benefit in Attending
Session:
The need to control healthcare costs and
maintain economy in the operating room mandates that surgical residents acquire
minimally invasive surgical skills prior to participating in actual
procedures. Operating room setup,
patient positioning and operating port placement are essential to operative
success. Errors in judgment and or
execution of these steps increase the difficulty of performing a procedure and
ultimately lead to prolonged operations, conversions to open surgery and
increased surgical morbidity. Imersive
virtual reality training allows residents to prepare for operative procedures
in an environment which provides feedback and monitors their individual
progress, and should decrease the impact of resident training on healthcare
cost and patient morbidity.
