Image capturing assembly and related endoscope

An endoscope comprising:

• an insertion tube;
• and
• an image capturing assembly connected to the insertion tube, the image capturing assembly comprising:
• a fixture comprising:
• a fixture body comprising a first end surface, a second end surface opposite to the first end surface, and a peripheral surface located between and connected to the first end surface and the second end surface, an accommodating space being formed on one of the first end surface and the second end surface of the fixture body, the accommodating space being defined by a recess structure on the one of the first end surface and the second end surface of the fixture body;
• and
• at least one first contact disposed on the fixture body;
• a lens assembly having an optical axis and engaged with the first end surface of the fixture body along the optical axis;
• an image sensing device disposed inside the accommodating space, the image sensing device comprising at least one second contact electrically connected to the at least one first contact;
• and
• a circuit board comprising:
• a board body detachably engaged with the second end surface of the fixture body along the optical axis, and the board body comprising a side surface;
• and
• at least one third contact disposed on the side surface of the board body and electrically connected to the at least one first contact;
• wherein the first end surface and the second end surface of the fixture body are arranged in order along the optical axis, the first end surface engaged with the lens assembly is perpendicular to the optical axis, and the side surface of the board body is parallel to the optical axis.
