1. A device including:
- (a) a shaft having at least one flexible portion along its length between a proximal end and a distal end;
(b) at least two longitudinally bendable pulling and/or pushing elements, the at least two pulling and/or pushing elements each extending to the proximal end of the shaft and each acting on the shaft in an axial direction of the shaft at locations spaced apart from the proximal end of the shaft further than at least part of the at least one flexible portion; and
(c) a fixing device located in a fixed position with respect to the shaft adjacent to the proximal end of the shaft, the fixing device having each of the at least two pulling and/or pushing elements extending there through, and being adapted to reside alternatively in a releasing position in which the pulling and/or pushing elements are unsecured to the fixing device and are substantially free to move axially there through, or a locking position in which each pulling and/or pushing element is fixed in place with respect to the fixing device.

Abstract
The invention relates to an endoscope-type device, particularly an endoscope for emergency intubation, comprising a holding portion (7) and a shaft (1) which is configured to be flexible at least in partial areas, with at least two longitudinal bendable pulling and/or pushing elements acting on said shaft (1) in the axial direction at different distances from the proximal end, with said pulling and/or pushing elements extending as far as the proximal end and being lockably received in a fixing device.

12. A device including:
-
(a) a shaft having at least one flexible portion along its length between a proximal end and a distal end; (b) at least two longitudinally bendable pulling and/or pushing elements, the at least two pulling and/or pushing elements each extending to the proximal end of the shaft and each acting on the shaft in an axial direction of the shaft at locations spaced apart from the proximal end of the shaft; and (c) a fixing device located at or adjacent to the proximal end of the shaft, the fixing device in a releasing position leaving the pulling and/or pushing elements unsecured to the fixing device so that the pulling and/or pushing elements are substantially free to move axially through the fixing device to enable the shaft to be bent to a desired shape, and the fixing device in a locking position locking the pulling and/or pushing elements in place with respect to the fixing device to retain the shaft in the desired shape. - View Dependent Claims (13, 14, 15, 16)

17. A method for operating an endoscope-type device having a shaft with at least one flexible portion along its length between a proximal end and a distal end and at least two longitudinally bendable pulling and/or pushing elements, the at least two pulling and/or pushing elements each extending to the proximal end of the shaft and each acting on the shaft in an axial direction of the shaft at locations spaced apart from the proximal end of the shaft, the method including the steps of:
-
(a) placing the at least two pulling and/or pushing elements in a condition in which they are freely movable axially at the proximal end of the shaft and bending the shaft to a desired longitudinally bent shape; (b) with the shaft in the desired bent shape, placing the at least two pulling and/or pushing elements in a condition in which they are in a fixed position prevented from moving axially at the proximal end of the shaft to fix the shaft in the desired bent shape; (c) inserting the shaft into an inserted position in an orifice while the at least two pulling and/or pushing elements are in the fixed position fixing the shaft in the desired bent shape; (d) with the shaft in the inserted position, placing the at least two pulling and/or pushing elements in the condition in which they are freely movable axially at the proximal end of the shaft; and (e) moving the shaft from the inserted position in the orifice while the at least two pulling and/or pushing elements are in the condition in which they are freely movable axially at the proximal end of the shaft. - View Dependent Claims (18)
