Quantification of the stress generated by the endoscopic movement in the brain parenchyma during intra ventricular surgical procedure

Figures & data

Figure 1. Personalized position of the model: mesh of the endoscope (blue) and the surrounding cerebral layer (red). The center of rotation of the endoscope (CR) corresponded to the enter point in the head. (Adapted from Netter 2002).
