Embodiment Construction

[0020]FIGS. 1-5 show the retractor 2 of one embodiment of the present invention that includes a blade 6 interconnected to a handle 10 that selectively interfaces with a gallows support 14. The blade 6 is curved about its longitudinal axis (A) to provide a semi-cylindrical profile. The blade 6 is also curved at the tip 18 at an angle (ϕ) relative to the longitudinal axis of the retractor 2. The retractor includes a maxilla portion 22 configured to maintain a patient's 26 mouth open, while the blade 6 keeps the patient's tongue 30 away from the roof of the mouth. The maxilla portion 22 is generally cylindrical, thereby providing an opening 34 and a passage 38 that receive and accommodate surgical instruments.

[0021]In operation, the handle 10 is positioned outside the patient's mouth and the blade 6 is positioned in such a way to ensure a clear path to the patient's oral cavity and, thus, the pharynx, larynx, and associated structures.

[0022]The tip 18 of one embodiment of the present i...

Abstract

A retractor used in inner-oral surgery is provided that includes a maxilla portion configured to maintain a patient's mount in an open state. The retractor also includes a blade that maintains the position of the tongue so that surgical tools are not obstructed. The maxilla portion of one embodiment only extends a portion of the length of the blade.

Description

[0001]This application claims the benefit of U.S. Patent Provisional Patent Application Ser. No. 62 / 307,333, filed Mar. 11, 2016, the entire disclosure of which is incorporated by reference herein.FIELD OF THE INVENTION[0002]Embodiments of the present invention are generally related to retractors used with laryngoscopes. More specifically, one embodiment of the present invention is a retractor supported by a gallows laryngoscope holder that facilitates the use of traditional or robotic medical instruments.BACKGROUND OF THE INVENTION[0003]Laryngoscopes are routinely used to facilitate endotracheal intubation of patients, to provide an air passage for administration of anesthesia, and / or to establish an airway. In addition, laryngoscopes are commonly used in surgery to displace pharyngeal tissues to permit direct inspection of the larynx (i.e. direct laryngoscopy). Many laryngoscopes are L-shaped having a handle connected to single curved or straight blade. Otolaryngologists typically...
