Abstract:
A surgical apparatus for remotely ligating a vessel using a suture loop comprising:an elongated cannula having a central axis between distal and proximal ends;a retractor, slidably supported by the cannula for translational movement substantially aligned with the central axis of the cannula and having a first portion disposed near the proximal end of the cannula and a second portion disposed near the distal end of the cannula, the second portion having a dissection cradle positioned at the distal end of the second portion,the dissection cradle comprising:a shoulder part, on the distal end of the retractor;a curved channel part, attached to a distal end of the shoulder part to allow the suture loop to abut against the distal end of the shoulder upon translation of the cannula;a manual controller disposed near the proximal end of the cannula for selectively controlling translational positioning of the cradle relative to the cannula; anda tension mount, selectively attachable to the distal end of the cannula, and extending forward of the distal end of the cannula, for selectively supporting a length of suture, and for maintaining the loop in tension for transport along the vessel.
