Technical Field

The invention relates to the technical field of endoscopes, in particular to an oblique focusing digital endoscope.

Background

Endoscopes are photographing devices for visually inspecting inaccessible places such as body cavities of human bodies, which can enter the stomach through the oral cavity or enter the body through other natural ducts, and can see lesions which cannot be displayed by X-rays by using the endoscopes, and therefore, the endoscopes are widely used in modern medical examinations. However, the endoscope in the prior art can only be focused in the straight direction, so when the endoscope is used for medical examination, medical staff need to hold the endoscope by hands to enable the lens to be directed to the examination part, and because the structure of the inner cavity of a human body is complex, when the endoscope meets a complex inner cavity, the endoscope with the structure is inconvenient to operate, and even cannot extend into the complex inner cavity for shooting examination. Therefore, there is a need for a digital endoscope that is convenient to use and can be focused obliquely.

Further, the range of contained angle β between the through-hole of direction shell and the axial of tubular metal resonator is 0 (< β < 90%), the preceding terminal surface of direction shell is equipped with the recess, be equipped with L ED lamp plate in the recess.

Furthermore, the upper end face of the lens is parallel to the upper end face of the metal tube, and the lens and the photosensitive element are coaxially arranged in parallel.

Furthermore, inner grooves are symmetrically formed in the inner wall of the handheld portion of the handle shell, a PCB is clamped on the inner grooves, the lower end of the PCB is connected with a transmission interface, a single chip microcomputer and a plurality of function keys are connected to the PCB, and the transmission interface is electrically connected with the single chip microcomputer; the transmission interface passes through the tail cover and is exposed outside.

Furthermore, limiting salient points are arranged on two sides of the lower end of the PCB, the PCB moves upwards under the limitation of the limiting salient points, and the PCB moves downwards under the limitation of the tail cover.

Furthermore, the focusing moving part comprises an adjusting plate and a connecting block fixedly connected to the adjusting plate, a connecting rod inserted through hole is formed in the upper end of the connecting block, and screw rods for locking the connecting rod are arranged on two sides of the connecting block.

Compared with the prior art, the invention has the beneficial effects that: the endoscope has the advantages that a certain included angle is formed between the guide shell sleeve of the endoscope and the axial direction of the metal tube, the focusing movable piece is driven to pull the guide sliding plate through the rotation of the focusing ring, so that the photosensitive element on the guide sliding plate can only move along the axial direction of the lens, the oblique focusing observation is realized while the good optical relation and the image effect are kept, the endoscope can shoot and observe in an oblique corner, the use is more convenient, the use flexibility is higher, the shooting requirements of various complex inner cavities can be met, and a new technical support is provided for endoscopic examination.
