  • Publication number: 20230263375
    Abstract: An endoscope including a handle and an insertion cord having a bending section body, a first steering wire portion, and a second steering wire portion. The bending section body includes segments and hinges keeping together, and formed integrally with, the segments, a center axis and a center plane traversing the center axis, the center plane dividing the bending section into a first bending section side and a second bending section side, and the segments including passages that together form a working channel lumen having a non-circular cross-section. Steering wire lumens are displaced with respect to the center plane towards the first side and configured to accommodate the first and second steering wire portions.

  • Publication number: 20230148844
    Abstract: An endoscope including steering and braking mechanisms. The braking mechanism includes a manually operable braking control element, a friction element which is axially translatable along a control axis to engage or disengage with the steering mechanism, and a cam pairing transmitting force between the braking control element and the friction element and transforming the braking input into an axial translation of the friction element. The cam pairing has a cam surface and a cam axially contacting the cam surface. The cam surface forms a first ramp section for translating the friction element from a first braking position to an intermediate braking position, a second ramp section for translating it from the intermediate braking position to a second braking position, and an intermediate section forming a tactile structure arranged between the first ramp section and the second ramp section and defining the intermediate braking position.
