In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," and "fixed" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally formed; may be mechanically coupled, may be electrically coupled or may be in communication with each other; they may be directly connected or indirectly connected through intervening media, or they may be connected internally or in any other suitable relationship unless expressly stated otherwise. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.
Example 1
Due to the deformability of the hose and the slender shaft characteristic of the endoscope, the insertion is inconvenient in the insertion process, and the endoscope shaft is not tightly attached to the hose after the insertion, so that the imaging effect of the front end is affected, and the insertion is not smooth.
In view of the above technical problems, referring to fig. 1 and 2, an endoscope sheath provided in this embodiment includes a flexible tube 1 extending from a proximal end to a distal end, the proximal end of the flexible tube 1 forms a connection seat 2 communicated with the proximal end, a sealing valve 5 is disposed between the connection seat 2 and the flexible tube 1, the interior of the flexible tube 1 forms a sealed chamber when an endoscope is inserted into the flexible tube through the sealing valve 5, and specifically, the sealing valve is configured to allow the endoscope to pass through so as to be inserted into the flexible tube;
