Description

Detachable endoscope

[ field of technology ]

The utility model relates to the medical instrument technology, in particular to a detachable endoscope.

[ background Art ]

The endoscope is a commonly used medical instrument, can enter the human body through a natural cavity channel of the human body or through a minimally invasive incision, is inserted into an organ position to be inspected when in use, displays, amplifies and stores real-time images through a video connecting wire or a wireless connection endoscope image processor, and can be used for doctors to observe in real time and look back and print to form medical reports.

Endoscopy is a straightforward, gold standard for the diagnosis of many lesions and even cancers. However, the traditional repeatedly used endoscope has a complex structure and high price, and needs to be matched with complex cleaning and sterilizing equipment and professionals, so that the whole investment is large, and the endoscope is configured only in large hospitals or major departments, and primary hospitals, clinics and the like, so that a plurality of patients are not diagnosed in time in early stages, and the optimal treatment time is missed. Because the endoscope is medical equipment entering the body cavity, the front end part generally acts on the inside of the human body, and various substances such as body fluid can be adhered to the endoscope in the using process, and strict cleaning, disinfection or sterilization procedures are needed to ensure the using safety. However, because the endoscope has a complex design structure, high system integration and special used materials, places where cleaning, disinfection or sterilization is not thorough exist, and high risk of cross infection exists.

For these reasons, there are various risks associated with the use of conventional reusable endoscopes, and the use of disposable endoscopes is a priority for medical institutions and patients in performing endoscopy. In recent years, disposable endoscopes are also put forward in the market, and the disposable endoscopes can only be used once due to factors such as material selection, manufacturing process and the like, so that the disposable endoscopes are discarded integrally after being used, the energy consumption is greatly increased, the generation of medical wastes is greatly increased, and the disposable endoscopes are contrary to the concept of energy conservation and consumption reduction and earth environment protection advocated in the world at present. And the disposable endoscope can be used only once, thus increasing the purchase cost and the use cost of hospitals, being unfavorable for reducing the burden of patients and being contrary to the current national policy of increasing and reducing the burden of patients.
