Abstract

The invention discloses a disposable nail box for laparoscopic straight-line cutting stapling apparatuses. The disposable nail box comprises a nail box base, a nail box shell is installed in the rear of the nail box base, an upper nail-abutted seat cover is rotatably installed on the nail box base, a nail-abutted seat is installed in the upper nail-abutted seat cover, a nail bin is installed in the nail box base, a knife push slice is movably installed between the nail box base and the nail box shell, and a cutting knife is fixedly installed at the front end of the knife push slice; an elastic support used for keeping the upper nail-abutted seat cover open is arranged between the upper nail-abutted seat cover and the nail box base and comprises a V-shaped elastic piece, the first end of the V-shaped elastic piece is fixedly installed on the upper nail-abutted cover, and the second end of the V-shaped plastic piece is abutted against the upper surface of the nail box base or the upper surface of the nail bin. The fixing mode of the V-shaped elastic piece is solid and reliable, bouncing-off angle of a jaw cannot be affected due to looseness of the position where the elastic piece is installed, elasticity of the elastic piece is fully utilized, and the situation that the jaw can be opened to the maximum angle so that a doctor can hold diseased tissue to be removed to the right place is guaranteed.
