Method and apparatus for surgical occluding and cutting.

摘要

A surgical instrument for ligating and dividing a tubular vessel. The instrument has two spaced apart channels, each containing surgical ligatures of plastic or plastic-like material. A pusher mechanism associated with each of the channels advances the ligatures along the channels. A cutting mechanism intermediate the two channels is used to divide the tubular vessel. An actuating mechanism is connected to the pusher mechanism and to the cutting mechanism for initiating operation thereof. A sub-housing is associated with each of the channels and is movable with respect to the ligatures and with respect to the cutting mechanism. Ligatures are placed at two spaced apart positions of the tubular vessel to effect ligation. The vessel is divided intermediate the spaced apart ligatures while the vessel is advanced so as to facilitate ejection of the ligatures and prevent stretching of the tissue.
