Abstract
A surgical apparatus for suction attachment to a body tissue. The apparatus includes a tissue-engaging component defining a concave vacuum compartment. The vacuum compartment is connectable to a vacuum source. A valve selectively allows and prevents the generation of a vacuum in the vacuum compartment. The peripheral edge of the vacuum compartment is attachable by suction to the body tissue when the vacuum is generated. A valve closing arrangement automatically closes the valve upon the peripheral edge being separated from the body tissue so as to maintain vacuum generating efficiency for the other tissue-engaging components coupled to the same vacuum source.
