Abstract:
1. A surgical port assembly comprising: an annular holder disposable in an opening in a patient, said annular holder having an annular wall or sleeve, said annular wall or sleeve being an outermost portion of said holder so that said wall or sleeve is in contact with soft tissues of said patient at said opening upon a disposition of said holder in said opening, said annular holder configured and dimensioned to secure directly to the soft tissues of said patient; a cannula unit removably attachable to said holder so that said cannula unit is rotatable with respect to said holder about a longitudinal axis, said cannula unit comprising: a base removably attachable to said holder so as to be disposed at least partially inside said annular wall or sleeve, said base defining a closure surface disposed inside said annular wall or sleeve so that said annular wall or sleeve surrounds said closure surface; and a plurality of cannulas connected to said base so as to intersect said closure surface within said annular wall or sleeve, said cannulas defining respective access paths passing through said closure surface at mutually spaced locations so as to enable simultaneous insertion of multiple instruments through said closure surface at said locations, said cannulas being separate and distinct tubular members each fixedly connected at one end to said base so that portions of said cannulas contiguous with said closure surface are stationary with respect to said closure surface, wherein said closure surface is located in a main plane, each of said cannulas defining a respective secondary plane to said main plane, said base having a longitudinal axis, each said secondary plane being spaced from said longitudinal axis, and wherein said cannulas are at least three in number and said secondary planes are disposed at angles relative to each other.
