What is the origin of mattress for mattress suture pattern?

A surgical suturing strategy. The needle goes into the skin, over the incison and out through the skin on the other side; then a chomp parallel to the cut and on top of the skin; then once more through the skin, over the wound and out to the surface once more. It is attached to the closure of the suture if the example is to be an interfered with one. It may be intruded on or consistent, vertical or level, and immediate or crossed. The intruded on level example is called likewise the programmed edge suture, the four-line interfered with suture and the U-suture.
