Abstract
A surgical apparatus for the simultaneous resection of soft tissues and their suturing with metal staples comprises an anvil and a staple branches, hinge-connected and having longitudinal jaws situated one opposite the other. A longitudinal row of grooves is made on the jaw of the anvil branch for clinching the ends of staples, while slots for the staples with staple tappets placed therein are provided on the jaw of the staple branch opposite said grooves. A plank with a wedge bevel on its end intended for interaction with the staple tappets when ejecting the staples is situated in the slot of the staple branch, and is longitudinally movable therealong. Rotation shafts are set along each branch with needles set perpendicularly to them, intended for grasping the soft tissue. Rigidly secured on the shafts are cranks, movably connected through a link so that when the branches are being drawn together, this provides for the rotation of the shafts with the needles towards each other, resulting in the portion of the soft tissue, grasped by the needles, being forced into the clearance between the branches with the formation of a roll of soft tissue intended for excision. Situated on the s…
