Abstract: A simulated tissue structure for practicing surgical techniques is provided. In particular, a realistic organ model or tissue portion for practicing the removal of a tumor or other undesired tissue followed by suturing a remnant defect as part of the same surgical procedure is provided. The simulated tissue structure includes an artificial tumor disposed between layers of elastomeric material and mounted on a simulated organ wall or tissue portion. The simulated tissue structure is modular and interchangeable. At least one of the layers includes a mesh reinforcement. A defect comprising two juxtapositioned surfaces defining a gap between the surfaces is created in the simulated tissue structure and the trainee practices tumor removal and closure of the gap by suturing in a laparoscopic environment.

Abstract: When a semi-automatic weapon is live fired, its firing pin is reset and is ready to be fired again. The shooter's hands remain in the firing position, and just the trigger finger and trigger are employed. But with dry fire practice, the shooter must remove a hand from the weapon and ratchet the slide to reset the firing pin, allowing the trigger to return to its unfired position. This must be done each time a shot is simulated. This invention provides, by incorporating a modified ammunition magazine in the weapon's magazine compartment, realistic muscle memory training by duplicating the action of the trigger, the feel and the sound of the release of the firing pin and the resetting of the trigger for additional trigger activations. It does not interact with the weapon's firing pin and does not require any alterations to the weapon such as disassembling and reassembling of parts.

The display board assembly further includes a display board accessory including a projection. The display board accessory is removably coupled to the mounting member in one of a first position, in which the projection is received in the first gap, and a second position, in which the projection is received in the second gap.

Abstract: An olfactory training device and method replicating one or more aromas typical of any man-caused or natural incident or accident, especially such aromas accompanied by or originating in open, smoldering, or smoking fire. Such aromas may originate from burning tissue, bones, cartilage, or other bodily materials. Such burning aromas may also originate from other synthetic or natural materials. One or more such olfactory training devices may be dispersed in a manner to engage the olfactory-sensory system of a trainee. The olfactory training device may be classroom-deployed, field-deployed, laboratory-deployed, or deployed via any type of setting-deployable training device or protocol.

Abstract: The invention provides a dental model with an artificial jawbone with cavities, at least two artificial teeth, and interfaces each connecting a corresponding tooth to the jawbone such that it extends upwards from a corresponding cavity. To enable movement of the teeth relative to the jawbone and relative to the other teeth, the teeth are connected to the jawbone via interfaces which are more elastically deformable than the teeth and jawbone. In this way, a realistic dental model can be made in a very simple and cost efficient manner, e.g. in an SLS process. The invention further provides a method of making the dental model.

Abstract: A system for training a clinician in energy-based surgical techniques that advantageously does not require the simulated tissue to be electrically conductive is provided. The simulated tissue comprises one or more materials. A heat generator is configured in the shape of a medical instrument typically encountered in energy-based surgical procedures such as electrosurgery or electrocautery. The instrument delivers sufficient heat to melt at least one of the materials in order to simulate energy-based surgical techniques such as excising target material. The one or more materials are configured in the simulated tissue such that their relative thermoplasticity defines a predetermined surgical pathway of a desired clinical outcome.

Abstract: A simulated weapon includes a mechanical counting mechanism that incrementally advances upon firing of a simulated round. When the mechanical counting mechanism reaches a state indicating that all simulated rounds have been fired, a slide of the weapon is locked back, mimicking the lockback feature of an actual weapon. The simulated weapon may be untethered, enabling realistic training in weapon handling. The mechanical counting mechanism may be actuated by motion of the slide.
