ABSTRACT:
Disclosed is a splint or overtube device for use in keeping the sigmoid colon in a straightened position during endoscopy to facilitate advancement of the colonoscope or other types of medical endoscopes to the cecum. This device utilizes a distal seal made from a sponge-like material to close off the space between the endoscope and the splint at the distal end of the splint to prevent perforation of the colon. The distal seal can be tapered to further facilitate passage of the splint through the colon and minimize the likelihood of colon perforations. A hydrophilic lubricating substance is utilized to minimize friction between the endoscope and the splint. A second sealing member is utilized at the proximal end of the splint to prevent loss of fluids from the splint and to guide the endoscope through the splint. An injection port is provided to allow the endoscope operator to inject fluid to lubricate the distal seal, to enlarge the colon in advance of the splint and to clear a path through the colon for the splint.
