Endoscopic light refraction imaging techniques are described for configuring a viewing trocar and/or angled endoscope with a light refracting element, such as glass and/or plastic prism for instance. The light refracting element can be utilized in and/or with the viewing trocar to refract (i.e., bend) light passing into the trocar through the trocar's window. As a result, the angled endoscope's field of view can be substantially aligned with the field of view of the trocar's window, thus allowing the angled endoscope and viewing trocar to be used together to create ports in a patient, including initial ports of endoscopic surgical procedures.

An atomizing nozzle structured particularly for nasal therapy. Preferred embodiments include a 2-piece atomizing nozzle structured to couple with luer-locking structure carried by a syringe. Such an atomizing nozzle includes a nasal stopper and a stem. A preferred nasal stopper includes a distal tip sized for insertion into a nostril of a human child, with a proximal shield portion being structured to resist over-insertion of a discharge orifice into the nostril. A nasal stopper desirably provides a centering function to urge the discharge orifice away from a nasal wall. One operable stem is structured to couple with the stopper and desirably carries unitary thread structure at a proximal end. A second operable stem is structured as a unitary part of the nasal stopper and also desirably carries unitary thread structure at a proximal end. Certain embodiments may also include spacer structure configured to reduce a dead volume inside the atomizing nozzle. Other embodiments may also include spacer structure configured to reduce dead volume inside a syringe that is coupled to the atomizing nozzle.

An anesthetic dispensing device () particularly adapted to apply anesthetic agent to the oral cavity and upper tracheal area of a medical patient prior to intubation of such patient. An exemplary dispenser () includes a handle () operably connected to a retractor () that carries an anesthetic dispensing device (). A currently preferred dispensing device () includes a fluid-dispersing nozzle () in fluid communication with a syringe (). Sometimes, an optical device () is coupled to the dispenser () to permit direct visualization of the application of anesthetic agent.
