Abstract: Systems, devices and methods may include a device for feeding an endoscopy operating instrument into an endoscope. The device may include a housing coupled to a proximal end of the endoscope. The device may include a mechanism to advance the medical instrument in a rotational manner through the housing. The device may include a member forming an internal working channel and having an entry port, exit port, feeding system, and coupling structure.

Abstract: Disclosed are a system, a device, and a method of a lubricant applicator device to be used with an insertion tube of an endoscope. In one embodiment, a video system center having a processor and a memory; a monitor coupled with the video system center; a light source coupled with the video system center; an endoscope coupled the video system center having a control section; an insertion tube having a camera at a distal end of the insertion tube that permits viewing of an area of an internal structure that is directly in front of the camera; and a mirror to be mechanically extendable at a distance from the camera and reflected backward, so that the camera permits viewing of an area behind the camera through a reflection of an image produced by the mirror when an operator of the endoscope utilizes the control section of the endoscope.

Abstract: Disclosed are a system, a device, and a method of a lubricant applicator device to be used with an insertion tube of an endoscope. The lubricant applicator device includes a tubular member to surround a portion of an endoscope insertion tube such that the tubular member is extendable over the portion of the endoscope insertion tube to snugly surround the portion of the endoscope insertion tube. An enlarged bulbous region adjacent to a distal end of the tubular member is pre-filled with a gel material that is releasable onto a surface area of the endoscope insertion tube encompassed by the enlarged bulbous region. A handle region adjacent to a proximal end of the tubular member that extends from the enlarged bulbous region provides a non-slip exterior surface to enable a human hand of an operator to grasp the handle region and manipulate the endoscope insertion tube.
