摘要:
Systems and methods of removing bacterial biofilm from a target site using a biofilm removal endoscope. The endoscope has an insertion portion including an imaging channel terminating at a viewing window and an irrigation channel terminating at a nozzle. The imaging and irrigation channels are permanently affixed relative to one another. The insertion portion is inserted into the patient, with a working end thereof being disposed proximate the target site. The target site is imaged and a flow of fluid is dispensed via the nozzle to mechanically remove bacterial biofilm from the target site.
摘要:
A surgical micro-burring instrument including an outer tubular member coaxially maintaining an inner tubular member. The outer tubular member defines a proximal section, a distal section, and a central lumen extending from the proximal section to the distal section. The distal section forms a pocket and an elevator tip. The pocket has a bottom wall and an opposed upper opening. The elevator tip extends distal the pocket. The inner tubular member forms a bur received within the pocket. Upon final assembly, at least a portion of the bur is exposed relative to the outer tubular member via the upper opening of the pocket. The elevator tip is configured to facilitate lifting of soft tissue, such as mucosa, while positioning the bur, via the pocket, in an appropriate location for cutting contacted harder tissue, such as turbinate bone or septal bone/cartilage.
摘要:
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.
摘要:
Chronic Otitis Media with Effusion (COME), Recurrent Acute Otitis Media (RAOM), cholesteatoma, and other bacterial ear conditions may be treated by applying a solvating system containing greater than 0.2 wt. % surfactant to a bacterial biofilm in the middle or inner ear, disrupting the biofilm, and applying a protective layer of a polymeric film-forming medical sealant.
摘要:
The invention provides a polymeric medical sealant. The medical sealant is useful for application to the tonsils and adenoids, wherein the sealant performs at least one of the following functions, a) inhibit the colonization of bacteria, b) inhibit the binding of bacteria to tissue, c) reduction of tissue morbidity, d) hemostasis, e) coating and protection of tissue during healing. f) promotion of healing, and g) reduction of pain.
摘要:
A method of removing bacterial biofilm from a target site of a human patient. A bacterial biofilm removal system is provided that includes an endoscope, an irrigation duct and an aspiration duct. The endoscope includes a working end. The irrigation duct includes an outlet. The aspiration duct includes an inlet. The endoscope working end, the irrigation duct outlet and the aspiration duct inlet are disposed proximate a target site that includes a layer of bacterial biofilm. The target site is imaged with the endoscope working end. The fluid is dispensed through the irrigation duct outlet toward the target site to mechanically remove at least a portion of the layer of bacterial biofilm. The removed bacterial biofilm and the dispensed fluid are collected with the aspiration duct inlet.

Chronic otitis media and other bacterial ear conditions may be treated by applying a solvating system containing a metal ion sequestering agent and surfactant to a bacterial biofilm in the middle or inner ear. The solvating system disrupts the biofilm and aids in its removal.
