Purpose

We assessed the applicability of a new multidirectional videoendoscope digiCAMeleon, Karl Storz GmbH, Tuttlingen, Germany in various neuroendoscopic procedures.

Methods

A 4-mm-diameter rigid videoendoscope digiCAMeleon, Karl Storz GmbH, Tuttlingen, Germany with 1 sensor and an internal LED light source was tested. The device offers a resolution of 1920 x 1080 pixels and weighs ≈ 215 g. The prototype was tested on three cadaveric heads using three different approaches: a endoscopic endonasal transsphenoidal; b frontal transcortical intraventricular; c supraorbital.

Results

We identified several major benefits of the integrated system as applied to endoscopic endonasal, transcortical intraventricular, and endoscopic supraorbital keyhole approaches. These included improved maneuverability of the scope on account of reduced bulk and integration of the camera and fiberoptic light components, a variable angle of view from 0–70 degrees, and a novel feature that can be activated to maintain orientation of the surgical horizon. Our preliminary report highlights the potential for handling the videoendoscope in one hand, as one would a microsurgical instrument. The videoendoscope harbors all its electronic and lighting data into a unique and thin cable, thus resembling a modern -all-in-one- computer technology. Because of its reduced weight and ergonomic shape, controlling its movements is very easy and comfortable, even in the microsurgical environment. Furthermore, the videoendoscope offers the unique feature of orienting the horizon of vision, thanks to the possibility of offering angled views while working; this helps the surgeons to stay oriented with direct visualization and improved control of the instruments over a specific area of interest.

Conclusions

The videoendoscope prototype represents an HD-image quality versatile tool in a neurosurgical environment, thanks to its reduced weight and dimensions; in these preliminary simulations, we have identified optimized visibility and maneuverability as major benefits of this novel surgical adjunct.
