METHOD FOR HEPATIC TISSUE FIXATION AND LIVER CLAMP Russian patent published in 2018 - IPC A61B17/04 

FIELD: medicine.

SUBSTANCE: liver clamp consists of upper and lower rigid bars, curved towards each other, vertical supports each consisting of two parallel vertical plates, one of the vertical supports is hingedly connected to the upper rigid bar, in which there are holes of different shapes, over the lower bar, there is an elastic bar with common attachment points with the lower bar at both ends; a lock, structurally being an element of one of the vertical supports with serrated cuts of short plates that extend into the vertical support space from both of its side plates; a vertical rod with a conical-rounded form of vertex rigidly and fixedly attached to the lower bar passing through the opening in the elastic and upper bars, the rod has a movable lock with a lateral screw mechanism and a possibility of changing the position along the rod and around its axis. To fix the hepatic tissue, the upper rigid clamp bar is withdrawn up and to the side, a fixed vertical rod is directed, fixed on the lower rigid bar, through the entire thickness of the parenchyma, the upper rigid bar is returned in place, covering and pressing the liver site, snapping the free edge of this plate in the lock, then the movable lock with the lateral screw mechanism is put on the rod.

EFFECT: uniformity of compression, reduced risk of shear and slippage of the clamp.
