A dampener device configured for incorporation into a downhole tool in a drilling system for absorbing axial, lateral and torsional shocks and vibrations to protect instrumentation during a drilling process includes a main sleeve having a main cavity containing a main spring and a first elastomeric ribbon interleaved between coils of the main spring. An adapter is connected to or formed monolithically relative to the main sleeve. The adapter is configured for connection to a first tool component. A plunger is configured to compress the main spring and a connector is configured for connection to a second tool component. The connector is attached to or formed monolithically relative to the plunger. A shaft extends between the adapter and the connector. The shaft is provided with an anti-rotation structure.
