Virtual Reality Based Simulation of Hysteroscopic Interventions

Abstract

Virtual reality based simulation is an appealing option to supplement traditional clinical education. However, the formal integration of training simulators into the medical curriculum is still lacking. Especially, the lack of a reasonable level of realism supposedly hinders the widespread use of this technology. Therefore, we try to tackle this situation with a reference surgical simulator of the highest possible fidelity for procedural training. This overview describes all elements that have been combined into our training system as well as first results of simulator validation. Our framework allows the rehearsal of several aspects of hysteroscopy-for instance, correct fluid management, handling of excessive bleeding, appropriate removal of intrauterine tumors, or the use of the surgical instrument.

Pressure-dependent hydrometra dimensions in hysteroscopy

“…were only recorded and did not influence the selection criteria. The acquired knowledge about the elastomechanical behavior of the uterus is essential, e.g., when building a realistic virtualreality-based simulator for surgical training in hysteroscopy [7]. Anatomic attachments of the uterus are only located on both lateral sides of the corpus and the cervix, where the tight ligaments suspend the uterus in the lesser pelvis, allowing manifold enlargement, essential for human reproduction.…”

Establishing construct validity of a virtual-reality training simulator for hysteroscopy via a multimetric scoring system

“…As a proposed first step in the validation cascade [9], face validity has been established with high ratings for both realism and training capacity for HystSim [10], a new surgery simulator for diagnostic and operative hysteroscopy [11]. The presented results demonstrate that potential trainees and trainers accept HystSim as a realistic and useful tool for the training of hysteroscopic interventions.…”

Simultaneous cutting of coupled tetrahedral and triangulated meshes and its application in orbital reconstruction

“…Preforming titanium meshes for orbital floor reconstruction combined with CAPP leads to a more individualised treatment. Using simulations to train surgeons is also of high interest [25,26].…”
