Granted: 2020-01-29
Abstract: FIELD: transportation. 
     SUBSTANCE: invention relates to lifting cranes, namely, to tower crane extension. Tower winch is used to increase tower crane and section lifting is used. Pre-assembling winch is mounted under crane boom at its bottom and locking the turn circle of crane, for example, finger-bolt joint. Boom fore part is lowered by removing connecting pin and releasing tug-and-winch mechanism relative to articulated jib and boom fore part. Boom fore part is fixed by rod. Mounting cable rope is hooked by boom lug. Winch rope is blown off until the boom rests against its wheels in the guide rails located on the crane tower sections on the counter-shots side. Wire of the mounting winch is disengaged. Crane hook lifts required number of sections of crane tower by mounting them on each other. Crane hook lifts jib and installed on last raised section of crane tower. Wireline of the mounting winch is engaged with the boom lug by passing it through the goose roller. Crane tower section and the crane header are disconnected by removing the pin from the hinge eyes, leaving the boom to hang on the wincing attachment cable. Boom is pulled by the rope of the mounting winch upwards, moving the boom wheel along the guide rails until the hinge eye is aligned on the boom and on the tower section. Pin is inserted into the hinge. Wireline winch cable is used to remove wiring cable. Valve hook is removed by crane hook. Crane boom is returned to horizontal position by rope of mounting winch and secured to upper section of crane tower by means of finger-and-bolt connection. Boom fore part is lifted by means of traction-winch mechanism. Stopper is removed from the tapping wheel. 
     EFFECT: possibility to quickly and safely expand / disassemble tower crane sections of high-height tower, as well as possibility of transportation of all mounting elements by normal vehicles within standard transport dimensions.

Abstract: FIELD: medicine.  
     SUBSTANCE: invention relates to medicine, in particular to surgery, oncology, transplantology. Cadaveric liver exteriorization is performed. The portal vein is mobilized, one’s own hepatic artery, their branches and the retro-hepatic segment of the inferior vena cava, as well as the short hepatic veins that flow into the inferior vena cava are ligated and crossed. Next, the umbilical vein is mobilized in the round ligament of the liver and its recanalization is performed. The ends of the arteries in the round ligament are sealed. Then a cholecystectomy is performed. A venous cannula with an external diameter of 6 to 12 mm is installed and fixed in the umbilical vein. Next, an arterial cannula with a diameter of 2 to 4 mm is installed in the left branch of its own hepatic artery (OHA). Then a vascular turnstile is applied to the left branch of the OHA for sealing. The left branch of the portal vein (PV) is sealed to prevent perfusate leakage. After that, sealing is performed at the level of the terminal section of the intermediate and left hepatic veins, or in the presence of their common trunk. After that, a perfusion circuit is formed by connecting the inflow system, from the perfusion tank to the drug, to the cannula in the left branch of the OHA, the outflow system, from the drug to the reservoir, to the cannula in the umbilical vein. The circuit also includes tanks with perfusion solution and for collecting it at the outlet of the circuit, a perfusion pump, a thermostatic bath and connectors. Then, to determine the interlobular border of the liver, a solution of a water-soluble dye in a volume of 20 to 150 ml is injected bolus into the arterial cannula. Further, the identified interline boundary is marked with X-ray-positive objects. After that, isolated left-sided lobar arterio-umbilical perfusion of the liver is performed in the mode: perfusate flow rate 110-350 ml/min, duration 20-60 min, perfusate temperature 4-430°C. Further, during perfusion, in order to control the spread of perfusate in the parenchyma and possible leakage, a water-soluble X-ray contrast solution with a total volume of 100-150 ml is injected and fluoroscopy is performed. After that, the liver preparation is examined.  
     EFFECT: method makes it possible to improve the treatment of multiple mono- and bilobate liver lesions, as well as to create a basis for the development of new transplantation (“ex vivo”) technologies in abdominal surgery.
