ABSTRACT:
A suture ligating device for use with an endoscope includes a long hollow tube and an elongated, integral member, a resiliently-biased scissoring mechanism, a suture carrying mechanism and a suture grasping mechanism. The long hollow tube has a open end which has a inwardly beveled edge and a closed end and is adapted to be slidably inserted into the endoscope. The elongated, integral member is adapted to be slidably inserted into the long hollow tube through the open end and is shaped like a fork having a stem having a first end and a second end. A first elongated prong has a first end and a second end. A second elongated prong has a first end and a second end. The first and second prongs are joined at the respective first ends thereof to the stem at its first end. One scissor arm of the resiliently-biased scissoring mechanism is fixedly coupled to the long hollow tube at its closed end and the other scissor arm is pivotally coupled to the long hollow tube at its closed end in order to be able to retract the elongated, integral member from a first position. The suture grasping mechanism and the suture carrying mechanism are mechanically coupled to the first and second prongs at their second ends and are aligned so that they become engaged when the elongated, integral member is retracted from the first position to a second position so that a slip knot can be tied externally to the endoscope.
