Problems solved by technology

This is especially serious if the bleeding is severe and if time is wasted removing, cleaning and reinserting the lens
If a clean, unobstructed lens is not available quickly enough to identify and control the source of bleeding, the procedure is more likely to convert to an emergency "open" procedure requiring a large surgical incision

Embodiment Construction

[0095] figure 1 Various embodiments are shown in FIG. 24 . In one embodiment, the invention is a device comprising a hollow device body (6) designed to fit on an endoscope. The body of the device can be rigid or flexible. The body of the device may be sufficiently flexible to conform and mold to the shape of the endoscope. This flexibility can be achieved through the use of soft, elastic materials such as latex, rubber, plastic, or fabrics containing latex or other elastic fibers. The hollow device body defines a lumen shaped and sized to receive an endoscope of a particular desired size. The distal end of the device body can be opened or closed by means of a transparent window or lens cover (22). The device body (6) may define one or more internal guide channels (9), some of which pass through the lens cover film (3). The lens cover film is exposed through the first guide slit (7), passes in front of the lens cover (22) and the objective lens (2), and passes back into th...

Abstract

The invention encompasses devices and methods used to keep the objective lens of a viewing or illuminating device, specifically an endoscope, free from obstructive fluid and dirt; specifically a device having a hollow body designed to fit over an endoscope, a transparent lens cover film that is retained within the device and that is threaded in front of the objective lens of an endoscope, thereby maintaining a clear and unobstructed transparent window in front of the endoscope lens, and an endcap configured to engage opposing edges of the lens cover film in a sealing manner.

Description

[0001] 【Related application】 [0002] This application is a continuation-in-part of a related application, U.S. Provisional Patent Application Serial No. 61 / 918,855, filed December 20, 2013, and U.S. Patent Application Serial No. 12 / 663,573, filed December 8, 2009 (which Claiming rights and priority to PCT / US08 / 06923, filed May 31, 2008, and U.S. Provisional Patent Application No. 60 / 933,693, filed June 8, 2007). 【Technical field】 [0003] The present invention relates to a device which keeps the objective lens of a viewing or illuminating device, in particular an endoscope, free of debris during use without the need to remove it from the patient's body. Furthermore, variations of the invention prevent direct contact of the endoscope surface with body tissue surfaces, thereby eliminating the need to sterilize the endoscope. 【Background technique】 [0004] Certain medical procedures require a viewing device ("endoscope") to be inserted into a body cavity in order to view fea...
