Background

Currently, endoscopes are widely used in clinic for examination and treatment of lung, stomach, intestine, etc. At present, the inserting part of the endoscope is inserted into a part of a human body to be checked and treated, and then the endoscope can be reused only by cleaning and disinfecting, so that the cleaning and disinfecting steps are complicated, the consumed time is long, and the endoscope is difficult to rotate. And the condition of incomplete disinfection exists, so that cross infection is easily caused. At present, the insertion part of the disposable endoscope is discarded after use, and the disposable endoscope is expensive to use. In the treatment process, the head end of the endoscope can shift due to the entering of instruments, so that the treatment position is deviated. The insertion part of the endoscope adopts a disposable endoscope sleeve, and after the endoscope is used up, the endoscope sleeve can be reused only by being replaced, so that the endoscope is convenient and cheap, and the treatment position is more accurate.

When the endoscope sleeve is used together with an endoscope, the endoscope sleeve can only be used for examining organ parts, and if excessive body fluid such as blood, sputum and the like is found during examination and use, the body fluid cannot be sucked. The scope and limitation of the use of the endoscope sleeve is small. And the use of doctors is inconvenient, and other medical instruments are needed for suction. The head end of the endoscope also moves during treatment, so that the treatment position is deviated.

Therefore, the above endoscope sleeve is improved, and a novel endoscope sleeve having a function of sucking a body fluid such as sputum or blood and fixing a tip end of an endoscope at the time of treatment is added.
