The invention provides an endoscope and a head end device thereof. The head end device comprises a circuit board assembly, an illumination circuit board, an image acquisition part and an illumination part, a connecting end of the image acquisition part and an image acquisition cable are respectively and fixedly connected to the circuit board assembly, and the image acquisition part and the image acquisition cable are conductive through a conductive material arranged on the circuit board assembly; the illumination circuit board is provided with a groove edge used for forming a first groove, the image acquisition part penetrates through the first groove and is assembled with part or all of the groove edge, the illumination part is arranged on the first surface of the illumination circuit board, the illumination cable is located on one side of the second surface of the illumination circuit board, and the image acquisition part is arranged on the second surface of the illumination circuit board. The second surface and the first surface are distributed along a first direction, the first direction is the orientation of the image acquisition end of the image acquisition part, and the illumination part and the illumination cable conduct electricity through a conductive material arranged on the illumination circuit board.
Description
technical field [0001] The invention relates to the field of medical instruments, in particular to an endoscope and a head end device thereof. Background technique [0002] With the development of science and technology, endoscope technology based on flexible tubes has been widely used in the medical field, which can help medical personnel to check internal organs of the human body by inserting the endoscope into the human body. [0003] In the related art, an endoscope may include a flexible controllable bending tube and a head end device formed at one end of the controllable bending tube. The head-end device includes an image acquisition unit and an illumination source, and the connection terminals of the image acquisition unit and the illumination source can be welded with other wires by welding to realize electrical transmission. [0004] However, due to the small size of the image acquisition unit, the size of its wires is also small, and its welding with other wires m...
