[0004] In summary, there is a need for a rotating endoscope tube structure that can improve the observation range. Utility Model Content

[0005] The utility model aims to overcome the shortcomings of the prior art that only the image in front of the endoscope can be observed and displayed, the observation range is small and the limitation is large, and provides a rotating mirror tube structure of an endoscope capable of increasing the observation range.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

Under the transmission action of spur gears 1 and spur gears 2, the rotating block and the mirror tube on it can be driven to rotate, thereby increasing the observation range and enabling a more comprehensive observation of the internal tissues of the human body. The operation is simple and the control is convenient.

[0009] Preferably, a slide groove is provided on the handle, and the spur gear 2 is located at the end of the slide groove. A sliding pressure block matching the spur gear 2 is provided in the slide groove, and the sliding pressure block is slidably connected to the slide groove. A pressure block locking device is also provided at the end of the slide groove. In a natural state, the sliding pressure block is pressed against the spur gear 2, and the position of the sliding pressure block is fixed by the pressure block locking device, so that the spur gear 2 is in a locked state, thereby preventing the deflection of the mirror tube during observation by the doctor, and ensuring a good observation effect. When the mirror tube needs to be rotated and adjusted, it is only necessary to control the pressure block locking device to release the fixation of the sliding pressure block, and push the sliding pressure block to separate from the spur gear 2, so that the spur gear 2 can be smoothly turned, thereby rotating and adjusting the mirror tube, and the operation is simple and convenient.

[0010] Preferably, the pressure block locking device comprises a card slot located on the end wall of the slide slot, the card slot and the second spur gear are located at the same end of the slide slot, a card head matching the card slot is fixed on the sliding pressure block, and the card head and the card slot are engaged. In a natural state, the sliding pressure block is pressed tightly against the second spur gear, and at this time, the card head on the sliding pressure block is also stuck in the card slot on the end wall of the slide slot, thereby achieving a position fixing effect on the sliding pressure block.

Through the cooperation of the annular inclined surface and the arc-shaped concave surface, the contact area between the sliding pressure block and the rotating pressure block on the spur gear 2 is increased, thereby improving the clamping effect and preventing the spur gear 2 from deflecting.

[0012] Preferably, a friction layer is provided on the surface of the arc-shaped concave surface. The friction layer is designed to further increase the friction between the sliding pressure block and the rotating pressure block, thereby better improving the clamping effect to prevent the spur gear 2 from deflecting.

[0013] Preferably, one end of the mirror tube is fixed on the rotating block, the end face of the other end of the mirror tube is an inclined face, and a CCD camera and a color-changing light source are installed on the end face of the other end of the mirror tube. By using a color-changing light source to provide light illumination and using a CCD camera to take pictures of internal tissues of the human body, the imaging quality is greatly improved, and the diagnostic efficiency is improved. In addition, the CCD camera and the color-changing light source on the inclined end face of the mirror tube are rotated 360 degrees, which greatly increases the observation range of the CCD camera and improves the diagnostic efficiency.
