The utility model relates to a surgical stapling device. The surgical stapling device comprises a tool assembly which is provided with a U-shaped frame, an anvil block assembly and a staple cartridge assembly. The U-shaped frame has a proximal transverse portion, a longitudinal portion, and a distal transverse portion. The distal and proximal transverse portions of the U-shaped frame have a common shape with the cartridge assembly, the common shape including a first linear portion defining a first axis, a second linear portion defining a second axis, and a third linear portion defining a third axis, the first axis being transverse to the longitudinal axis of the elongate body. A first radius of curvature is defined between the first linear portion and the second linear portion such that the first axis and the second axis define an angle [beta], and a second radius of curvature is defined between the second linear portion and the third linear portion such that the second axis and the third axis define an angle
