FIELD: medicine, surgery.
SUBSTANCE: the present innovation deals with intraoperational diagnostics of benign lesions in extrahepatic biliary ducts. The suggested device has got a hollow chlorovinyl tube with a fixing ligature applied through tube's lumen. Fixing ligature is designed to be a metal one: its one end is in the form of a hook the external diameter of which corresponds to internal tube's diameter. The device suggested enables to loosely fix and remove the drainage of cystic duct in case of laparoscopic cholecystectomy by not applying conventional operational accesses.
EFFECT: higher efficiency of diagnostics.
