摘要： A surgical stapling device (10) is disclosed for performing circular anastomoses. The surgical stapling device includes a handle portion (12), an elongated body portion (14) and a head portion (16) including an anvil assembly (30) and a shell assembly (31). The surgical stapling device includes a knife blade (188) possessing a lubricious coating which enhances the ability of the knife to cut through tissue and minimizes the knife sticking to tissue or other components of the surgical stapling device. The coating comprises at least one polydialkylsiloxane and at least one siliconization material.
