Endoscopes generally refer to medical instruments that enter the human body through various ducts to observe the internal condition of the body. The lesions that cannot be seen by X-rays can be seen with an endoscope, so that it is very useful for doctors. Such as by an endoscopist, to view ulcers or tumors in the stomach, whereby an optimal treatment regimen is established. Some endoscopes have therapeutic functions such as cystoscope, gastroscope, coliscope, bronchoscope, laparoscope, etc. The initial endoscope was made of a rigid tube and was invented more than 100 years ago. Although they have gradually improved, they have not yet been widely used. Later, endoscopes were made of flexible tubing in the 50 s of the 20 th century, and thus were able to bend easily at the corners within the human body. In 1965, harlod Hopkins endoscopes were equipped with cylindrical lenses to make the field of view clearer, today's endoscopes typically have two fiberglass tubes through one of which light enters the body, and doctors observe through the other tube or through a camera, some endoscopes even with miniature integrated circuit sensors, and feed the observed information back to a computer. However, damage or failure may occur because the objective lens group is affected by various reasons during use. If a lens in the objective lens group needs to be replaced, it is often necessary to determine the type and specification of lens to be replaced and then disassemble, clean and install.

Specifically, the medical endoscope machine assembly further comprises: an illumination optical fiber 2, an eyepiece 3, a power supply 8, a display module 9, an image processing unit 10, a light guide beam 7, and a light source 601; the light source 601 is located inside the objective lens 1, and the light source 601 is located at a position corresponding to the independent lens 501; the power supply 8 is electrically connected to the motor 27.
Specifically, the rotating rod is located at the middle position of the arc chute 15 in a natural state; when the rotating disc 5 rotates by a certain angle, the independent lens 501 rotates to the corresponding position of the preparation lens 31.
Working principle:
when the innermost individual lens 501 of the objective lens 1 is damaged, a certain angular change can be produced by rotating the rotating disc 5, so that said individual lens 501 is rotated to the corresponding position of said spare lens 31 for replacement. At this time, the connecting rod 13 slides relatively in the arc chute 15, ensuring smooth operation. Rotation of the connecting rod 13 drives the first spring 12 to press the rotating rod 18 and the third spring 17 down to keep the mechanism stable. At the same time, the rotating rod 18 is in contact with the fixed rod 19, further supporting and positioning the relevant components.
In order to ensure the accuracy and efficiency of the operation during the replacement of the individual lenses 501, the motor 27 is energized with the power supply 8 in order to activate the relevant mechanical means. The motor 27 drives the driving shaft 28 to move, so as to drive the sliding rod 25 to move forwards. The sliding rod 25 smoothly enters the carrying case 33, and continues to move forward, pushing the preparation lens 31 to press the independent lens 501. Thereby, the preliminary lens 31 is moved forward, gradually replacing the position of the individual lens 501. The replaced individual lenses 501 drop in the process to the collection bin 11 for subsequent processing.
Meanwhile, to ensure the stability and safety of the mechanism operation, the independent lens 501 further compresses the fourth spring 23 under the action of pressing down the pressing block 22. At this point, the squeeze block 22 is disconnected from the sense block 32, avoiding unnecessary interference and intervention.
After the replacement of the individual lenses 501 is completed, the motor 27 is disconnected from the power supply 8 to stop the associated actions in order to avoid accidents. The slide bar 25 is gradually returned under the action of the restraining spring 29, thereby releasing the rotary shaft 4. The rotating shaft 4 is reset under the action of the first spring 12, so that the normal function of the objective lens 1 is ensured to be recovered.
In summary, through a series of precise and orderly actions and coordinated operations, the independent lens 501 of the objective lens 1 smoothly completes the replacement process, so that the required functions and performances of the independent lens 501 can be continuously exerted, and the normal operation of related equipment and systems is ensured.
