SURGICAL INSTRUMENT CONTAINING FLEXIBLE SYSTEM OF HINGED JOINT Russian patent published in 2020 - IPC A61B17/72 

FIELD: medical equipment.

SUBSTANCE: invention relates to surgical stapling and cutting tools and cassettes with staples intended for use with them. Surgical stapling instrument comprises a rod, an end effector, a hinged joint, a trigger system and a hinged wire. Rod includes a core frame. End effector comprises a frame of the end effector and a branch. Branch is movable relative to the frame of the end effector. Hinged joint includes a hinged joint frame, a first hinged joint and a second hinged joint. Hinged joint frame comprises a proximal end of the hinged joint and a distal end of the hinged joint. First hinged joint connects the proximal end of the hinged joint with the core frame. Second hinged joint connects the distal end of the hinged joint with the frame of the end effector. Starting system is movable relative to the core frame, the hinge joint frame and the end effector frame. Starting system comprises a cutting element movable relative to the frame of the end effector. Hinged wire is rigidly fixed to the frame of the end effector. Hinged wire is configured to receive a compressed configuration when applying a compressive load and transfer force in the hinge joint to the frame of the end effector when applying a compressive load.

EFFECT: invention makes it possible to ensure use of wire for hinged rotation of end effector.
