Classification: CPC A  G | IPC A  G

Claim 18:
19. A medical device system, comprising:
an insertion tube;
a steering knob for articulating a section of said insertion tube;
a first articulation actuator;
a first shaft coupled to the first articulation actuator;
a first sleeve coupled to the steering knob, wherein the first shaft is received in the first sleeve and wherein the steering knob and the first sleeve are coupled, such that rotation of said steering knob causes rotation of said first sleeve;
a first braking system configured to brake the first articulation actuator, said first braking system comprising:
a first braking actuator, wherein the first braking actuator includes a pin received in the first shaft, and
at least one brake body, wherein the at least one brake body extends radially outward from said pin and is configured to move between a retracted position and an extended position, wherein the at least one brake body is configured to brake the first articulation actuator in the extended position, and wherein the at least one brake body is configured to move radially outward when transitioning from the retracted position to the extended position;

a second articulation actuator; and
a second braking system configured to brake the second articulation actuator, the second braking system comprising:
a braking lid,
a braking disc configured to move between an extended position, wherein the braking disc is engaged with the braking lid, and a retracted position, wherein the braking disc is disengaged from the braking lid, and
a second braking actuator, wherein the second braking actuator is configured to transition the braking disc between the retracted position and the extended position.
