Referring to fig. 1 and 2, an endoscope protection sleeve according to an embodiment of the present utility model is used to sleeve a connection endoscope, and includes a fixing sleeve 100, a protection tube 200, and a fixing buckle 300.

A fixed sleeve 100 for being sleeved on the handle of the endoscope. An endoscope is a common medical instrument and generally comprises a handle and an insertion tube, one end of the insertion tube is connected to the handle, the insertion tube is mainly used for being inserted into a human body cavity, and the handle is used for being gripped and fixed; for flexible endoscopes, a turning knob is also typically provided on the handle for manipulating the bending of the insertion tube. Specifically, the fixing sleeve 100 is generally sleeved on a tapered sheath of the endoscope, where the tapered sheath is a portion of the handle connected to the insertion tube, so the fixing sleeve 100 also generally has a tapered inner cavity, and in this embodiment, the fixing sleeve 100 is generally funnel-shaped.

The protection tube 200 is used for being sleeved on the insertion tube of the endoscope, and one end of the fixing sleeve 100 is connected with one end of the protection tube 200. The protective sleeve is sleeved on the insertion tube, so that the insertion tube can be isolated from contacting with the external environment, and mainly, when the insertion tube is inserted into a human body, the insertion tube is isolated from contacting with various tissues and body fluids in the human body, so that the endoscope is prevented from being polluted; therefore, the endoscope protection sleeve can be applied to a reused endoscope product, a disposable endoscope with higher overall cost is not needed, the medical cost is reduced, after the endoscope is used, only the endoscope protection sleeve is required to be detached, a new endoscope protection sleeve is sleeved and connected, the endoscope can be reused, the cleaning, disinfecting and sterilizing cost is low, and the risk of cross infection can be effectively reduced.
