METHOD FOR OBSERVING VISCERAL ORGANS STATE Russian patent published in 2000 - IPC

FIELD: medicine. SUBSTANCE: method involves piercing abdominal cavity wall, making laparoscopy and setting canal dilator in the abdominal cavity wall. To prevent from complications, the canal dilator is introduced in closed state into laparoscopic trocar during the primary examination. Then the trocar is removed and the secondary examination is carried out by introducing the laparoscope unit between lateral parts of the canal dilator brought apart. The canal dilator has detachable cylinder with openings to apply restrictors like clothes-pegs for longitudinal mixing. The cylinder has removable cover with core which diameter corresponds to cylinder diameter in closed state. To avoid longitudinal displacements, the cylinder parts are fixable in closed state with locking connection. Notches for placing threads cover the outer surface of the cylinder, its internal side having grooves for canal dilator branches to be fixed. EFFECT: excluded mobility restrictions and traumatic lesions of muscular aponeurotic layers of lateral regions in the abdominal cavity; enhanced effectiveness of canal treatment without removing canal dilator. 1 dwg
