Abstract: A quick release mechanism for detachably interconnecting a bronch tube with a laser micromanipulator. The bronch tube is provided with a channel aligned transversely to the tube axis and opening downwardly at an angle of approximately 45 degrees. The micromanipulator bracket includes a complementary pin adapted to receive the bronch tube channel thereon and to guide and position the tube in proper orientation. The micromanipulator bracket further includes an externally threaded barrel and bevelled locking nut which is threaded downwardly onto the bronch tube thereby locking the bronch tube against the bracket pin.
