Systems and methods for removal of bacterial biofilm from a target site of a human patient includes a surgical instrument having an introducer for bodily insertion and maintaining an irrigation duct and a nozzle. A distal portion of the introducer is transitionable between a plurality of bend angles relative to a proximal portion thereof. In particular, the instrument is adapted to independently maintain the distal portion at each of the plurality of bend angles relative to the proximal portion. The nozzle is maintained relative to the distal portion of the introducer and is adapted to dispense pressurized irrigant from the irrigation duct toward a layer of bacterial biofilm.

L'invention concerne des systèmes et des procédés pour éliminer un biofilm bactérien d'un site cible chez un patient humain, qui comportent un instrument chirurgical équipé d'un introducteur à insérer dans le corps et à maintenir un conduit d'irrigation et une buse. Une partie distale de l'introducteur peut passer entre plusieurs angles de cintrage par rapport à une partie proximale de celui-ci. Plus précisément, l'instrument est conçu pour maintenir de manière indépendante la partie distale à chacun des angles de cintrage par rapport à la partie proximale. La buse est maintenue par rapport à la partie distale de l'introducteur, elle est également destinée à distribuer un agent d'irrigation sous pression provenant du conduit d'irrigation en direction d'une couche du biofilm bactérien.
