Access assembly

摘要

An access assembly is provided. The access assembly includes an access member defining a central longitudinal axis and having a longitudinal opening therethrough for reception and passage of surgical instrument, the access member dimensioned for positioning within tissue to provide access to underlying tissue, and first and second seal members mounted to the access member in juxtaposed relation, the first seal member defining an opening therethrough, the second seal member defining an elongated arcuate passage, wherein the first and second seal members are adapted for rotational movement about the central longitudinal axis whereby the opening of the first seal member is axially alignable with the elongated arcuate passage of the second seal member to permit reception and passage of the surgical instrument in substantial sealed relation therewith, the first and second seal members further adapted for relative rotational movement whereby the first seal member is capable of rotating relative to the second seal member during manipulation and traversal of the surgical instrument through the elongated arcuate passage of the second seal member to maintain the substantial sealed relation about the instrument.

1. An access assembly comprising:
an access member defining a central longitudinal axis and having a longitudinal opening therethrough for reception and passage of first and second surgical instruments, the access member dimensioned for positioning within tissue to provide access to underlying tissue; and first and second seal members each defining a substantially circular base mounted to the access member in juxtaposed relation, the first and second seal members each having first internal surfaces defining an opening therethrough and second internal surfaces spaced from the central longitudinal axis and defining an elongated arcuate passage extending through an arc which subtends an angle greater than 0° with respect to the central longitudinal axis, the opening of the first seal member and the elongated arcuate passage of the second seal member being radially spaced from the central longitudinal axis, the elongated arcuate passage being arranged to at least partially circumscribe the central longitudinal axis; the first and second seal members adapted for rotational movement about the central longitudinal axis whereby the opening of the first seal member is axially alignable with the elongated arcuate passage of the second seal member to permit reception and passage of the first surgical instrument in substantial sealed relation therewith and the opening of the second seal member is axially alignable with the elongated arcuate passage of the first seal member to permit reception and passage of the second surgical instrument in substantial sealed relation therewith, the first and second seal members further adapted for relative rotational movement whereby the first seal member is capable of rotating relative to the second seal member during manipulation and traversal of the first surgical instrument through the elongated arcuate passage of the second seal member to maintain the substantial sealed relation about the first surgical instrument.
