Anatomical simulator for videoendoscopic surgical training
First Claim
1. An anatomical simulator for surgical training, comprising:
- a synthetic anatomical structure including at least one vessel having a resilient wall, the vessel being filled with a fluid; and
a synthetic connective tissue bonding the vessel wall to the synthetic anatomical structure and defining a tissue plane having a predetermined thickness and tear strength, the connective tissue being incisable to permit selective dissection of the vessel from the anatomical structure while maintaining the integrity of the vessel wall.

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.
