AI Technical Summary

Benefits of technology

"The present invention provides a method and device for positioning a working device within the ear, nose, throat or cranium of a patient using an endoscope and a guide device. The guide device allows for better visualization and easier placement of the working device without the need for an assistant. The endoscope can be held with the guide device, allowing for one-handed operation and reducing the need for an operating room. The invention also reduces the amount of fluoroscopy and image guidance systems needed. The guide device includes a tubular guide and a sheath for easy placement. Overall, the invention improves the accuracy and efficiency of procedures and reduces patient and user exposure to radiation."

Problems solved by technology

Indeed, in most traditional FESS procedures, if the uncinate process is allowed to remain, such can interfere with endoscopic visualization of the maxillary sinus ostium and ethmoid bulla, as well as subsequent dissection of deep structures using the available rigid instrumentation.

Embodiment Construction

[0088] Before the present devices and methods are described, it is to be understood that this invention is not limited to particular embodiments described, as such may, of course, vary. It is also to be understood that the terminology used herein is for the purpose of describing particular embodiments only, and is not intended to be limiting, since the scope of the present invention will be limited only by the appended claims.

[0089] Where a range of values is provided, it is understood that each intervening value, to the tenth of the unit of the lower limit unless the context clearly dictates otherwise, between the upper and lower limits of that range is also specifically disclosed. Each smaller range between any stated value or intervening value in a stated range and any other stated or intervening value in that stated range is encompassed within the invention. The upper and lower limits of these smaller ranges may independently be included or excluded in the range, and each range...
