Endoscope handle with frame

An endoscope comprising:

• an image sensor;
• one or more cables;
• a circuit;
• a steering actuator including trunnions, the steering actuator being rotatable about a pivot axis extending through the trunnions;
• wire tubes comprising a first wire tube and a second wire tube;
• steering wires configured to steer a distal end of the endoscope, the steering wires comprising a first steering wire extending from the steering actuator to and through the first wire tube and a second steering wire extending from the steering actuator to and through the second wire tube;
• a bending section;
• an insertion tube between the bending section and a handle, the wire tubes and the steering wires extending through the insertion tube;
• and
• the handle attached to the insertion tube and including:
• a frame comprising a single component including, as integral portions of the frame, a proximal end and a distal end, bearings at the proximal end, and a first wall portion between the proximal end and the distal end, the bearings receiving the trunnions and rotatably supporting the steering actuator;
• a second wall portion formed separately from the frame;
• a liquid-tight chamber accommodating the circuit, the liquid-tight chamber being at least partly defined by the first wall portion of the frame and the second wall portion, the liquid-tight chamber comprising a liquid-tight port, the one or more cables being connected to the circuit and extending through the liquid-tight port, the first wall portion comprising a proximal wall and a distal wall opposite the proximal wall, and the wire tubes extending longitudinally along opposite sides of the frame and proximally of the distal wall;
• and
• a first shell part and a second shell part together enclosing a cavity and accommodating the frame within the cavity,
• wherein the first shell part and the second shell part and the frame each are formed as separate components.
