END-TO-SIDE ANASTOMOTIC STAPLING DEVICE AND METHOD FOR A TUBULAR ORGAN

摘要

An end-to-side anastomotic device for a tubular organ according to one embodiment of the present invention comprises: a guide tube having a channel formed at one side thereof and a first tube installed inside through the channel; a moving ring surrounding the outside of the guide tube, and moving along the longitudinal direction of the guide tube; a first pressurization ring surrounding the outside of the guide tube, and moving along the longitudinal direction of the guide tube towards the moving ring to get exposed outside the guide tube via an opening of the guide tube in order to fix one side of the first tube everted on the outside of the moving ring; a piston installed in a manner to surround the outside of the guide tube so as to pressurize an anastomosis ring installed on the outside of the guide tube towards the front; and a plurality of movable sliders installed on the outside of the guide tube, the sliders shifting to a first position in parallel with the longitudinal direction of the guide tube and to a second position at right angles to the longitudinal direction of the guide tube, each slider having a guide groove formed on the rear surface thereof to guide deformation of a fixing pin formed at the anastomosis ring.
