  • Publication number: 20230233067
    Abstract: A sliding motion transfer member (22) for the kinematic chain of an actuator mechanism of an endoscope. The sliding motion transfer member (22) has a proximal end and a distal end (21). The sliding motion transfer member (22) is adapted to receive motion activation input and to move in a sliding manner in response to said motion activation input, thereby transferring motion to an elongate motion transmission member (27) extending from the distal end (21) of the sliding motion transfer member (20). The sliding motion transfer member (22) comprises a first passage (36) adapted for receiving a proximal section of said elongate motion transmission member (20) and an adhesive.

  • Publication number: 20230172439
    Abstract: A braking mechanism for a rotary operating member (9) of a medical device such as an endoscope. The braking mechanism includes at least one elastic member (18) adapted for biasing a friction element (19) into a frictional engagement between a stationary shaft arranged on the endoscope handle and the rotary operating member (9). The friction element (19) includes a curved surface and the elastic member (18) comprises a spring which, as seen in the radial direction of the rotary member (9), has a cross-sectional shape with at least one U-shaped section.

  • Publication number: 20230157519
    Abstract: A handle (4) for an endoscope (1) includes a first shell-shaped (6) housing part and a second shell shaped housing part (7) adapted for mutual engagement so as to form a housing. The shell-shaped housing parts (6, 7) include a first recess (10) and a second recess (11) so arranged and configured that when the first and second shell-shaped housing parts (6, 7) are mutually engaged, a circumferential recess is provided in the exterior surface of the housing. The handle (4) further includes a hoop (28) adapted to be received in the circumferential recess and hold the first and second shell-shaped housing parts together.

  • 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.
