Abstract

<p>Object. Pulsed water jet surgical instrumentation is intended to achieve both maximal lesion resection and functional maintenance through preservation of fine vessels and minimal surrounding damage. To proceed to clinical application in neuroendoscopic surgery, the aim of the present study was to develop the experimental set up to quantify the amount of debris dispersion under water application and to reduce the amount of debris.Methods. Brain phantom stained by methylene blue dye was dissected with ADPJ in the water. The net weight of brain phantom was calculated by spectrophotometer. The relationship between jet strength, suction rate, structure distance between suction tube and target, the effect of adding outer suction tube, and amount of dispersion was evaluated.Results. The net weight of dispersed debris could be measured by absorbance of methylene blue dye. The amount of dispersion decreased adding outer suction tube and increased the suction rate.</p>
