Patent number: 11622671Abstract: A movement transfer mechanism for a surgical scoping device, wherein a rotational proximal input force is transformed into a longitudinal force that is conveyed down the length of an instrument channel of the scoping device, where it is transformed again into an operational movement of a distal instrument. The operational movement can be rotational movement, but may be any movement that changes the orientation or configuration of the distal instrument. By conveying a linear force along the instrument channel rather than a twisting force, the problems of slipping and discontinuous operation of the distal instrument due to friction between the instrument and the instrument channel can be reduced or eliminated.Type: GrantFiled: May 16, 2017Date of Patent: April 11, 2023Assignee: CREO MEDICAL LIMITEDInventors: Christopher Paul Hancock, George Ullrich, David Webb, Louis Turner
