Endoscope device with off axis view

An endoscope device, comprising:

• an operation processor;
• and
• a detection module electrically connected with the operation processor, the detection module comprising:
• a tube;
• an optical transmission component having a first part and a second part bent to each other, a predefined included angle being formed between a structurally longitudinal direction of the second part and a structurally longitudinal direction of the first part;
• an optical detector located above the first part;
• a signal transmission component coupled with the optical detector, having a structurally longitudinal direction parallel to the structurally longitudinal direction of the second part, and the predefined included angle being formed between the structurally longitudinal direction of the signal transmission component and a detection planar normal vector of the optical detector;
• a first holder, comprising a first accommodating structure being a first chamber configured to accommodate the optical detector;
• and
• a second holder, comprising a second accommodating structure being a second chamber, two opposite ends of the first part respectively being embedded into the second chamber and abutting against the optical detector, the optical transmission component and the optical detector being assembled between the first holder and the second holder to install inside the tube.
