Introduction. Knotting is one of the essential surgical skills and vitally important processes that depends on its correct execution. The acquisition of these skills requires motor work, friendly and realistic environments. A strategy to facilitate learning the knotting technique is to generate accessible simulation instruments. Methods. A surgical knot simulator is presented, built with low-budget materials and affordable for the general population, with a budget of approximately $5,000 COP (US$ 1.23). Results. A surgical knot simulator has been developed in a way that, when attached to the thigh of a lower extremity from a seated position, provides a stable surface to effectively perform knot tying practice. Conclusion. Modern surgery considers patient safety as the top priority, so it is no longer appropriate to adopt a "see one, do one, teach one" training method. Constant practice using simulators is the most appropriate method. This work presents an alternative for uninterrupted learning of surgical techniques related to knots. [ABSTRACT FROM AUTHOR]
