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.
A suture ligating device for use with an endoscope, said suture ligating device comprising: a. a long hollow tube which has a open end and a closed end and which is adapted to be slidably inserted into the endoscope, said open end having a inwardly beveled edge; b. an elongated, integral member which is adapted to be slidably inserted into said long hollow tube and which is shaped like a fork having a stem having a first end and a second end, a first elongated prong having a first end and a second end and a second elongated prong having a first end and a second end, said first and second prongs being joined at said respective first ends thereof to said stem at its said first end; c. a first scissor arm which is fixedly coupled to said long hollow tube at its said second closed end; d. a second scissor arm which is pivotally coupled to said long hollow tube at its said second closed end and which is adapted to retract said elongated, integral member from a first position; e. resilient biasing means for resiliently biasing said second scissor arm with respect to said first scissor arm so that said elongated, integral member is normally in said first position; f. suture carrying means for carrying a suture, said suture carrying means being mechanically coupled to said first prong at said second end thereof; g. suture grasping means for grasping the suture, said suture grasping means being mechanically coupled to said second prong at said second end thereof whereby said suture grasping means and suture carrying means are aligned so that they become engaged when said elongated, integral member is retracted from said first position to a second position so that a slip knot can be tied externally to the endoscope.
