Publication number: 20230148844Abstract: 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.
