Abstract
An anatomical simulator system (10) includes a synthetic anatomical torso (12) resting on a base (14). The torso includes an internal cavity (18) and a pneumoperitoneum wall (16). A selected one of a variety of procedure packs (20, 30) is placed inside the cavity for use in training in videoendoscopic surgical techniques. The torso includes a plurality of trocar apertures (22) which permit insertion of videoendoscopic instruments for manipulation, incision, dissection and suturing of synthetic anatomic structure included in the procedure packs. Each procedure pack includes simulated anatomic structures (34,36,38,40) that have a realistic appearance and density, that provide realistic tactile feedback during manipulation and incision, and that are suturable and/or electrocauterizable using endoscopic instruments. The anatomic structures included within the procedure packs are joined together with synthetic connective tissue that is severable to allow dissection of structures without damaging the underlying structures. Pressurized vessels (36) containing synthetic bodily fluids are included to simulate dissectable blood vessels, bile ducts and the like.
