Suture techniques and knots
In this work, we use the reinforcement of learning feedback using graphic animation.The student stands up, with relaxed shoulders and arms slightly bent at an angle of 45 to 50°. Movements should be performed with low amplitude for the purpose of more delicate and precise movements.Regarding the positioning of the trocars for the execution of the suture, it must be such that the camera is in the middle, between the two trocars, positioned laterally so that the instruments pass through the trocars at an angle of 45° to each other.Initially, the student receives guidance as to the positioning of the suture thread for apprehension and placement inside the black box, using the Maryland forceps, with the hand opposite the hand of the needle holder.The needle was placed on a surface to facilitate its grasp, due to the lack of depth in the video, which works in two dimensions. The auxiliary forceps must hold the thread 3cm from the needle to position it.The needle after grasping can be adjusted in three different ways in the needle holder: by the thread, by the needle or using the surface used in the training, touching the needle tip and opening the needle holder jaw a little for a brief rotation (
