Introduction
In recent decades, laboratory animals mainly used in surgical research have been used more and more frequently. This is due to the good acceptability of guinea pigs in drug trials; These models become models because they reproduce human pathologies and enable us to enhance our understanding of some of the pathophysiological mechanisms of today's known diseases. Faced with the importance of surgical research for animal use, researchers developed surgical retractors.
Objective
Surgical retractors are an innovation in their field because they allow researchers to deal with his guinea pigs independently, without the need for anyone else to assist him. Once the fractured walls of the animal under study remain fixed and supported by the present invention.
