Abstract: An RF hand instrument wherein the RF ablation function ceases to operate prior to any RF tip detachment occurring, in order for the hand instrument to fail gracefully and thus be considered fail-safe. A mechanical retention mechanism which is separate to the RF power delivery means so the power is delivered by a separate electro/mechanical connection.
