Features of the Nasco Life/form Suture and Stapling Practice Trainer Set: Made with a soft vinyl skin over a core of stitchable foam to provide a lifelike suturing experience for students or a realistic suturing demonstration by an instructor. Realistic skin texture with wrinkles, pores, and visible fingerprints. Soft and pliable for easy sewing, the skin is tough enough that sutures will not pull out when tightened. Each unit provides three pre-existing “wounds.” These “wounds” can be sutured repeatedly until the skin around them is finally worn out; then, new “wounds” can be cut. Although disposable, the trainers provide hundreds of suturing experiences before wearing out. Conservatively, over one hundred cuts can be made on each trainer and each of these cuts can be sutured several times. Set consists of one Practice Arm (LF01028U) and one Practice Leg (LF01034U). Each trainer comes with a starter package of sutures and instruction booklet. Three-year warranty.
