Abstract:The design for our epidural simulator aims to tackle the issues previously identified. Novel aspects of our epidural simulator include 3D graphics, modeled vertebrae, spine flexibility, patient variation and accurate haptic force feedback based on measured needle insertion data.
The simulation contains all 26 spinal vertebrae as 3D models. The simulated needle can be inserted at any spinal position from L5 – T2. The 3D graphics allow a close up real time view of the needle internally during insertion.
The virtual patient can adjust to various body shapes, sizes, weights and heights. Body size considerably affects insertion force. The haptic device can recreate forces for each body size based on data from our clinical trial.
The spine in our 3D model can bend and flex in real time, to allow simulation of various patient positions including sitting, lying on the side, lateral decubitus and flexing, which increases the spacing between vertebrae.
