Abstract

Abstract A method and an arrangement for teaching suturing techniques in surgery. A tube of plastic material is adjustably mounted on a surface by means of two clamps, the positions of which are adjustable as well as their spring tensions. A portion of the tubular wall has been cut or removed. This plastic tube simulates various tissues of the human body. A cylinder having a pair of confronting cut-outs is placed on the supporting surface on top of the tube, this cylinder simulates a body cavity of the human body in which a surgical operation is to be carried out. The separated tubular walls of the plastic tube can be sewn together by means of known suturing tools and techniques thereby simulating a natural surgical operation and teaching various suturing techniques.
