Title (EN) METHOD OF SIZE MEASUREMENT IN MONO-VISION SCOPE IMAGE
(FR) PROCÉDÉ DE MESURE DE TAILLE DANS UNE IMAGE ENDOSCOPIQUE MONO-VISION
Abstract:
(EN) An embodiment in accordance with the present invention provides a method for accurate and objective quantification of stone fragment size. The method includes intraoperative measurement of objects during URS. The method analyzes URS procedures for ureteral and renal stones during basket extraction of fragments. An instrument is passed through an instrument channel of the ureteroscope and advanced until it is adjacent to the stone fragment to be measured. The measurement of stone fragment size is based on the known distance of a tip of the instrument in the ureteroscope's visual field.
(FR) Selon un mode de réalisation, la présente invention concerne un procédé de quantification précise et objective de la dimension d'un fragment de calcul. Le procédé comprend la mesure peropératoire d'objets pendant une URS. Le procédé analyse des procédures URS pour des calculs urétéraux et rénaux pendant l'extraction en corbeille de fragments. Un instrument est introduit dans un canal pour instrument de l'urétéroscope et avancé jusqu'à être adjacent au fragment de calcul à mesurer. La mesure de la taille du fragment de calcul est fondée sur la distance connue d'une pointe de l'instrument dans le champ visuel de l'urétéroscope.
