Surgical Instrument Electrical Contact Membrane Protection

The patent employs insulative membranes as flexible thin film barriers that cover electrical contacts. These membranes are flexible enough to allow insertion of sharp contacts while maintaining fluid tightness, thus preventing fluid ingress while preserving electrical connection capability when needed.

The insulative membrane acts as an intermediary element between the electrical contacts and the fluid environment. It mediates by providing a barrier that prevents direct contact between conductive elements and conductive fluids, while still allowing controlled electrical connection through sharp contact insertion.

The insulative membranes are pre-installed and positioned to cover electrical contacts before fluid exposure occurs. This preliminary protective action ensures that when fluids are present, the contacts are already protected, yet electrical connection can be established when needed by inserting sharp contacts through the membranes.

The system transitions from a static covered state to a dynamic connected state. The insulative membranes remain in place for protection, but sharp contacts can dynamically pierce through them to establish electrical connections when required, and then self-close to restore protection.

The sharp contacts are designed to self-close after puncturing the membrane. Once the electrical connection is established, the contacts automatically return to their original position, causing the membrane to self-seal around the contact point. This self-service mechanism restores fluid protection without manual intervention.

The membrane is designed with sufficient thickness and material properties to accommodate the puncture and subsequent self-closing action. This beforehand cushioning in the form of membrane elasticity and structural design ensures that the temporary breach does not compromise overall membrane integrity or fluid protection capability.
