Abstract

La présente invention concerne un dispositif d'élimination de calcul comprenant : une unité d'endoscope dans laquelle une caméra est disposée au bout d'un tube d'endoscope inséré le long d'un organe interne ou d'une cavité corporelle et capture des images à l'intérieur de l'organe interne ou de la cavité corporelle, et qui délivre les images capturées par l'intermédiaire d'un moniteur ; et une unité d'élimination de calcul qui est insérée le long de l'intérieur du tube d'endoscope de l'unité d'endoscope et élimine sélectivement le calcul. Une règle graduée pour estimer la taille du calcul à l'aide d'une réalité augmentée est disposée dans un tube de guidage, un panier ou une sonde de broyage de l'unité d'élimination de calcul, ou sur un écran du moniteur. Etant donné que la règle graduée peut être utilisée pour estimer la taille du calcul à travers un endoscope avant la capture du calcul, le temps pour une procédure d'élimination de calcul est réduit, et l'élimination de calcul est facile.
