Benefits of technology

The present invention is about a retractor for use with laryngoscopes. It can accommodate traditional or robotic medical instruments. The retractor has a blade that is curved to provide a cylindrical passage for the medical instruments. The retractor also has a maxilla portion that is shorter than the blade and is interconnected to the blade. The maxilla portion has first and second lateral edges and an arcuate surface that includes an outer portion having a larger length than the first and second lateral edges. The blade has a curved profile about its longitudinal axis and a tapered shape. The maxilla is adapted to fit around a patient's upper teeth and has an opening to accommodate a surgical instrument. The technical effect of this invention is to provide a specialized tool for medical procedures that can be easily and safely used with laryngoscopes.

Problems solved by technology

Alternatively, laryngoscopes are used, albeit less effectively, with jaw spreaders where mouth and larynx tissue are moved by various retractors interconnected to a peripheral structure positioned about the patient's head.
One drawback of using jaw spreaders, for example, those manufactured by Olympus® under the trade name FK-WO TORS, is that the retractors used are ineffective for endolaryngial surgery.

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...
