Description

Technical Field

[0001] The utility model relates to the technical field of endoscopes, in particular to an endoscope outer sleeve. Background Art

[0002] After each use, the endoscope needs to go through a strict disinfection and sterilization process. It is very likely that it is taken out for a second use without being soaked for the specified time, which makes its use unreliable and causes cross infection. Therefore, disposable endoscope overtubes are used to protect the endoscope.

[0003] However, the length of the existing endoscope outer sleeves on the market is generally customized, and each sleeve can only be used with an endoscope of a specified length. During the operation, it takes time to search and install the outer sleeve of the specified model with the endoscope, which will delay the operation. For this reason, we propose an endoscope outer sleeve. Utility Model Content
