Abstract

La présente invention concerne un endoscope urétéral qui possède une section transversale semi-circulaire et un corps d'endoscope frontal à courbure réglable. Ledit endoscope comprend un corps d'endoscope (2) et un boîtier d'endoscope (10). À l'extrémité dudit boîtier d'endoscope (10) sont disposées une poignée d'actionnement multi-canal et une gaine d'endoscope urétéral à diamètre variable (11). Ledit corps d'endoscope (2) possède une section transversale semi-circulaire, et son extrémité avant (1) est semi-molle. L'angle de l'endoscope peut être réglé via une poignée de réglage d'angle d'endoscope (4) placée à l'arrière du boîtier d'endoscope (10). La gaine d'endoscope urétéral à diamètre variable (11) possède une section transversale de forme ovale. Le corps d'endoscope semi-circulaire (2) présente un encombrement réduit dans une cavité de l'urètre, ce qui accroît l'espace d'évacuation de calculs. La gaine d'endoscope urétéral à diamètre variable (11) élargit le diamètre avec le support du corps d'endoscope (2), et le passage d'évacuation de calculs est ainsi élargi, ce qui facilite l'évacuation de l'eau et des calculs.
