Zusammenfassung:A surgical stapling device includes an anvil assembly and a shell assembly. The anvil and shell assemblies each include splines that define guide channels. Each of the anvil splines defines a distally positioned triangular tip that is defined by an apex and first and second right cam surfaces. The cam surfaces of the anvil splines are configured to engage one of the shell splines to cam or rotate the anvil assembly into alignment with the shell assembly as the anvil assembly is moved in relation to the shell assembly to a clamped position.
