this seam module has all increased first back up coat on the inner wall of first breach, second breach and third breach, and the student can carry out epidermis and sew up training, subcutaneous training and deep layer and sew up the training. The sewing notch is not easy to tear, so that the service durability of the sewing module is greatly improved. The atraumatic area that is pre-left in the middle provides incision training as well as deep suture training. In this way, the user can perform all the sewing exercises on the same sewing module, rather than just the skin sewing exercises as with other products. The wound-free area can provide the best tension in incision training, and the wound can be naturally opened during incision training by only padding any strip-shaped article below the area.
