Linear cutting element with E-shaped guiding element

A linear cutting element with an E-shaped guiding element enables the suture and cutting of surgery to be simultaneously conducted when being loaded in a linear cutting anastomat. The linear cutting element comprises a knife underlaying plate, a nail abutting seat, an assembly cover, suture nails, a nail cartridge, a push sheet, a guiding element, a pin for the guiding element, a cutting knife, a knife stand, a positioning needle, a positioning needle holder and a blank cap. The knife underlaying plate and the nail abutting seat are fixedly connected through a front-end groove and rear-end agnails of the knife underlaying plate. The nail abutting seat is fixedly connected to the guiding element through the pin for the guiding element. The guiding element is placed at the open end of the nail cartridge, and the guiding element enables nail grooves at the two sides of the nail cartridge to remain parallel vertically, which enables the nail cartridge in an open state to be in a closed state. The assembly cover is arranged between the nail abutting seat and the nail cartridge, and can be removed from the linear cutting element. The linear cutting element is replaceably loaded into the linear cutting anastomat.
