METHOD FOR DEVELOPING A SLIDING KNOT Russian patent published in 2006 - IPC A61B17/04 

FIELD: medicine, surgery.

SUBSTANCE: the present innovation could be applied in the course of endoscopic operations dealing with extracorporal development of a flat knot loop, spiral and a knot. The spiral should be formed out of 3 coils. One should wind one end of ligature around a flat knot loop with a coil to locate both ends at one side. Then the same end of ligature should be introduced into a coil to be tightened at simultaneous tension of another end to develop a knot. Then one should tighten two knots as a counter-tightening lock around each loop's branch successively with free end of ligature. As a result, formation of a spiral out of three knots enables to deform a flat loop that enhances friction power and makes the knot to be more compact and stronger. The innovation decreases the chance of a sliding knot for unbinding due to tissue pressure upon it from inside.

EFFECT: higher efficiency.
