The innovative laryngological cannula facilitates the precise collection of highly diagnostic material from the nose and sinuses in order to improve the diagnostic and therapeutic process

Abstract

Despite the use of state-of-the-art methods of pharmacological and surgical treatment, patients with chronic sinusitis suffer from recurrent infections which do not respond to treatment. The presence of bacteria in the sinuses structures is confirmed by microbiological tests. The subject of the application is a set of three cannulas dedicated to collecting microbiological samples, a biological material of high-diagnostic value originating from paranasal sinuses. Traditionally the collection of samples is associated with a risk of contamination resulting from presence of randomly collected microorganisms. Sometimes antibiotic therapy is based on the random microorganisms, driving attention away from the proper causative factor of the disease. The application of the invention allows for a non-invasive and quick collection of highly diagnostic samples for proper microbiological testing. The dedicated tip makes it possible to precisely reach natural sinus ostium or sinus ostium created during surgery without contacting other tissues. The samples obtained through the application of the invention reflect the microbiological condition of the sinuses. An incorrectly collected smear from the sinus mucosa surface may misdirect the therapy. The use of advanced model will effectively reduce such errors. In addition, it will contribute to the precise collection of material for testing, without artifacts or contamination by microorganisms present in other structures outside the sinuses. Therefore in the next step application of targeted antibiotic therapy based on antibiogram profile eliminates bacteria that penet
