Product information
Rigid endoscope is composed of two parts, the imaging system and Light guide system. The imaging system includes an objective lens system, a cylindrical lens, an eyepiece system, and a light guide system. The main component is an optical fiber. The optical fiber and the working tube are a semi-finished product. If the optical fiber is damaged or more, the optical fiber and the working tube of the mirror need to be replaced.
The cylindrical lens plays a key role in the imaging system. The cylindrical lens is a group of glass lenses whose diameter is proportional to the hard mirror working tube. The smaller the diameter of the hard mirror, the smaller the diameter of the lens and the easier it is to be damaged. Each hard mirror is composed of a group of lens components, and the focal length of the entire mirror is controlled by an inter-ring.
Common hard lens phenomena that affect clinical examination and treatment include image blur, image fogging, image blackening, one-third image rainbow image
and so on. There are many reasons for these phenomena
The most common problem that causes image blur is damage to the cylindrical lens, leakage of the lens body, and looseness of the optical system.
The most common reason for image fogging is leakage of the lens body. There is water vapor in the lens body, and the water vapor adheres to the lens to form fog.
The culprit of blackened images is also the problem of water leakage in the lens body. This phenomenon can also occur when the lens group is seriously damaged.
The crescent image can also be understood as a third image or a three-quarter image, etc. In short, the image is incomplete, mainly due to lens damage.
The rainbow image is caused by the shattering explosion of the lens.
Overall, the imaging system is the key to the above phenomena and the causes of the phenomena and failures, that is, the focal length of the cylindrical lens objective system. The hard mirror itself is an expensive and easily damaged precision instrument. Any irregular operation may cause damage to the components. Therefore, we are required to standardize every aspect of the operation, cleaning, sterilization, storage and transportation.
Common non-standard operations in clinical practice include the following
Picture Picture
Incorrect handling methods, such as taking the hard scope together with other instruments, which can easily cause the instruments to interact with each other. Collision can easily lead to loosening of the optical system and blurring of the image. Taking the working tube part of the hard mirror in the picture can easily cause the hard mirror to fall
and break the cylindrical lens in the working tube.
This mirror is a Shunkang resectoscope. During the resection process, the resection ring directly burns the ceramic head and then the working tube fiber and objective lens system of the mirror. Because it is important to remember the length of the retraction ring during electroresection surgery. Or, when retracting the resection ring, retract the resection mirror appropriately so that the mirror itself does not need to be burned.
During operation, cleaning or transportation, accidental drops or collisions may cause damage to the mirror. Therefore, it is recommended that each mirror be equipped with a special packaging box
to store or transport the mirror to avoid accidental damage. necessary damage.
When cleaning, hard mirrors cannot be cleaned with ultrasonic waves, but it is recommended that surgical instruments be cleaned with ultrasonic waves.

Transporting or cleaning together with other instruments can easily cause scratches on the mirror surface and may damage the lens. It is recommended that the special lens and box be cleaned separately.
To avoid damage to hard lenses, it is recommended to assign dedicated personnel to take care of them, handle them gently without collision or squeezing, clean them in a timely manner and avoid incorrect sterilization methods.
It is recommended that our company optionally equip the endoscopic sterilization box to protect the endoscopic endoscope, starting with professionalism!
All endoscopes sold by our company have a one-year non-human factor warranty. Lifetime paid maintenance!
