Detachable linear cutting anastomosis device

The invention provides a detachable linear cutting anastomosis device. The detachable linear cutting anastomosis device comprises a nail closing assembly, a first gasket, a nail containing assembly and a cutting assembly. A first gasket connecting structure is arranged on the nail closing assembly, the first gasket is detachably connected with the nail closing assembly through the first gasket connecting structure, and the first gasket connecting structure can limit the position of the first gasket; the cutting assembly can move in the cutting direction relative to the nail closing assembly, and in the cutting movement process of the cutting assembly, the cutting assembly can cut the first gasket and push the first gasket out in the nail abutting direction so that the first gasket can be separated from the nail closing assembly. According to the detachable linear cutting anastomosis device, the fixing effect on the first gasket can be improved, and the push-out convenience and the assembly convenience of the
