    • The dilating device of the preferred embodiments includes a three dimensional dilating surface that functions to dilate an orifice, an alignment surface that functions to align and center the dilating device to the orifice, a coupling element that functions to couple the dilating device to the surgical instrument, a removal element that functions to facilitate the removal of the dilating device from the surgical site such as a hole and/or a grasping surface. The dilating device is preferably designed to dilate an orifice to the size of a surgical instrument, thereby facilitating the use of a surgical instrument during surgery and, more specifically, facilitating the use of a circular stapler in laparoscopic surgery. The dilating device, however, may be alternatively used in any suitable environment and for any suitable reason.
    • 优选实施例的扩张装置包括用于扩张孔的三维扩张表面,用于使扩张装置对准和对准孔的功能的对准表面,用于将扩张装置连接到手术器械的联接元件 ,用于促进从外科手术部位(例如孔和/或抓握表面)移除扩张装置的移除元件。 膨胀装置优选地被设计成将孔扩张到手术器械的尺寸,从而便于手术中使用外科器械,更具体地,便于在腹腔镜手术中使用圆形缝合器。 然而,扩张装置可以替代地在任何合适的环境中使用,并且由于任何合适的原因。
