Abstract
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. The present device utilizes an elongated member having a tight distal end or seal to close off the annular space between the endoscope and the elongated member at the distal end of the splint to prevent perforation of the colon. A hydrophilic lubricating substance can be utilized to minimize friction between the tight distal end or seal and the splint. An injection port is provided to allow the endoscope operator to inject fluid to lubricate the distal end or seal, to deflect away the colonic wall in advance of the splint and to remotely lubricate the scope distally. A second sealing member can be utilized at the proximal end of the splint to prevent loss of fluids from the splint.
