1. One kind be used to connect cavity or hollow internal organs at two adjacent unfolded stapling apparatus in chamber interface place, comprise woven tube of wire, it has the end that vertically separates;

  • Have the design of eclipsed wire mesh screen, said pipe can longitudinal extension, so that cause the length of said pipe to become longer;

    It is littler that diameter becomes, and said pipe is to use hot marmem, and elastic metallic yarn or compressible tinsel are processed;

    Have in the end of woven tube of wire a plurality of circumferentially and longitudinal openings, make said pipe can be when the hole of the wall on the chamber interface that is arranged in anastomotic position of inserting two adjacent cavitys distortion and turn up the terminal heat or the mechanically deform of said pipe;

    And turn up, so that form petal as follows, its compresses and keeps the wall of said two adjacent cavitys to be in involutory state;

    Wire diameter and/or material property to said pipe are selected;

    So that the mechanical force of said unfolded pipe causes said unfolded pipe temporarily to stay put, up to fully healing occurring, at this moment;

    Said unfolded pipe comes off;

    Stay coincideing of ability proper function, when said Guan Youre marmem was processed, it upon deployment can be with vertical compressed format annealing.
