Problems solved by technology
Additionally, some endoscopic systems leave droplets on the imaging device and / or lenses, and these droplets may obstruct the view through the lens and / or imaging device
Application of irrigation fluid and suction removes debris and items that obstruct viewing, but irrigation fluid may remain on lenses or imaging equipment even after suction is applied such that irrigation fluid continues to obscure the surgeon's field of view

An endoscope sheath comprising: (a) a proximal end, (b) a distal end having a distal end region, (c) extending between the proximal end and the distal end and a surface connecting the proximal end and the distal end, (d) a plurality of positioning devices positioned along the surface; and (e) one or more droplet retention features; wherein said A sheath is configured to: (i) accommodate all or a portion of an endoscope and (ii) provide a conduit for inserting the endoscope into the endoscope sheath when the endoscope is inserted into the interior of the sheath. communicating fluid between the proximal end of the endoscope sheath and the distal end of the endoscope sheath; and wherein the plurality of positioning devices are positioned at the distal end of the endoscope sheath in a distal end region of the endoscope such that the endoscope is secured within the endoscope sheath; and wherein the one or more droplet retention features are configured to create a The scope sheath and the endoscope define an area to hold a volume of fluid via capillary action.
Description
technical field [0001] The present teachings generally relate to a system including an endoscope sheath that facilitates washing the lens and / or imaging device of the endoscope and prevents fluid and / or droplets that distort the user's field of view Formed and / or retained on a lens and / or imaging device. Background technique [0002] Endoscopes are commonly used in minimally invasive surgical procedures, or to provide access to internal locations in a patient, allowing visual access for a physician. During use, the endoscope may be inserted into a location that may include debris that may cover the endoscope end, and in particular cover the imaging device positioned at the endoscope end such that imaging is obscured. For example, an endoscope used in surgery may be covered with blood, and the blood may affect the surgeon's field of view, making surgery more difficult. Attempts have been made to provide various devices and systems to assist the surgeon in removing debris fr...
