Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, and further relates to an endoscope with a detachable motor box. Background Art

[0002] Endoscope is a commonly used medical device that can directly enter the natural cavity of the human body for inspection and provide doctors with sufficient diagnostic information. Traditional endoscopes have a precise structure and many tiny switches, making it difficult to disassemble the parts one by one for cleaning and disinfection. Even tiny residual microorganisms and secretions provide a possible environment for cross-infection. Disposable endoscopes are gradually used in clinical experiments and some diagnosis and treatment fields, becoming a supplement to traditional endoscopes. Disposable or single-use endoscope examinations reduce the risk of cross-contamination and hospital-acquired diseases.

[0003] During the current use of endoscopes, doctors need to manually twist the product's rotating device or turn their wrists to achieve angular rotation of the product. After the instrument is inserted into the channel tube of the endoscope, the overall rotation damping load increases, making it more difficult to rotate. After rotating to the required angle, rebound will occur, which is not conducive to positioning and affects the smooth progress of the operation.

[0004] As a disposable product, the motor accounts for a large part of the cost. Existing disposable endoscopes use motors for auxiliary transmission to improve the convenience of operation, but disposable endoscopes are disposable products. Considering the cost of the product, only low-end motors can be used, and more sophisticated motors with more functions cannot be used, thus failing to realize more intelligent telemedicine and artificial intelligence functions. Utility Model Content

[0005] The utility model aims to provide an endoscope with a detachable motor box so as to improve the convenience of operation and control the cost at the same time.
