ENDOSCOPE WITH A BENDING PORTION

摘要

An endoscope (1) comprising a control handle (2), a flexible insertion portion (3) having length L1 and being attached to the distal end of the control handle, a bending portion (4) having length L2 and being attached to the distal end of the flexible insertion portion, a rigid tip portion (5) having length L3 and being attached to the distal end of the bending portion, a control mechanism arranged to control the bending of the bending portion, and an elastic covering member (12) which is arranged to cover the bending portion and where the distal end of said elastic covering member is attached to the distal end (16) of said bending section and/or to said rigid tip portion (14) and where the proximal end of said elastic covering member is attached to the flexible insertion portion (18) and/or to the proximal end of the bending portion. The elastic covering member is arranged such that it is stretched when the bending portion is in its neutral position. In this way a low cost and flexible bending portion is provided.
