Publication number: 20120302834Abstract: A cover for a laparoscope having a substantially gas-impermeable, flexible membrane defining an interior space adapted to receive at least a distal-most portion of the laparoscope; and at least one valve for allowing gas to flow into and/or out of the interior space. By providing a substantially gas-impermeable, flexible membrane, the membrane can conform to the camera in use, ensuring that the cover can be used with both rigid and flexible laparoscopes and in particular those with cameras at their distal end. The valve allows gas to flow into or out of the interior space. This may be used to remove gas from the interior space so that the cover conforms more closely to the profile of the endoscopic camera. It may also be used to check that there has been no damage to the cover during the operation, and thus no breach of the sterile barrier.Type: ApplicationFiled: February 2, 2011Publication date: November 29, 2012Applicant: SURGICAL INNOVATIONS LIMITEDInventors: Michael White, Michael John McMahon

Patent number: 8262561Abstract: An endoscope provided with hygiene protection includes a cover, which is closed at its distal end and which is transparent for optical information, at least on the front side thereof, and which can be rolled thereon in the direction of the axis of the endoscope. The endoscope further includes one or more working channels extending in a parallel position in relation to the endoscope and terminating in an open manner on the distal end of the cover. The working channels are only connected to the distal end of the cover. There are also one or more vacuum channels having one or several openings, which terminate on the side facing away from the patient and are in addition to the one or more working channels. The working channels are positioned in between the outer side of the endoscope and the inner side of the cover. A method for adding hygiene protection to an endoscope, which includes the application of sub-atmospheric pressure between the endoscope and the cover, is also disclosed.Type: GrantFiled: December 5, 2003Date of Patent: September 11, 2012Inventor: Jürgen Kress
