SURGICAL STAPLER ANVILS WITH TISSUE STOP FEATURES CONFIGURED TO AVOID TISSUE PINCH

AThe invention provides anvils for surgical devices designed to cut and staple tissue. The anvils include tissue stop arrangements for positioning the tissue to be cut and stapled in the device so that the tissue is stapled prior to being cut. The anvils are moved between open and closed positions by a corresponding closure member. The tissue stops and/or closure members are configured to avoid adjacent tissue from being pinched between the closure member and tissue stops when the anvil is in a closed position. 本发明提供了用于被设计成切割和缝合组织的外科装置的砧座。砧座包括组织止动件布置结构，以用于将待切割和缝合的组织定位在装置中，使得组织在被切割之前被缝合。砧座通过对应的闭合构件在打开位置和闭合位置之间运动。组织止动件和/或闭合构件被构造成能够在所述砧座处于闭合位置时避免相邻组织被夹在闭合构件和组织止动件之间。
