Patent ID: 8777888

Claim:
A method of applying a liquid or powder in a body cavity of a living body, the method comprising: positioning a distal portion of an applicator in the living body by advancing the distal portion of the applicator through a trocar in a wall of the body cavity, the applicator comprising: a nozzle including an elongated nozzle main body and a nozzle head at a distal end side of the nozzle main body, the nozzle main body possessing a distal end portion that is curved or bent without application of a force to the distal end portion so that the distal end portion of the nozzle main body is configured as a curved section, the curved section being flexible; and an outer tube in which is positioned at least a part of the nozzle main body, with the nozzle head and the curved section extending distally beyond an open distal end of the outer tube, and a longitudinally extending gap between an inner surface of the outer tube and an outer surface of the nozzle main body; relatively moving the outer tube and the nozzle so the curved section moves proximally relative to the outer tube and enters the outer tube to adjust a direction in which the nozzle in the cavity body is facing; conveying the liquid or powder through the nozzle main body and to the nozzle head; expelling the liquid or the powder from the nozzle head toward a surface in the body cavity; and discharging gas in the body cavity into the longitudinally extending gap and to outside the body cavity.
