under the normal state, the opening of the soft protective cover faces the rear direction, and when the pushing pipe pushes forwards along the fixed pipe and props against the soft protective cover, the soft protective cover turns forwards to the reverse direction (namely the opening of the soft protective cover faces the front direction).

The front end of the pushing pipe can be provided with a seam or not along the axial direction, but in order to further facilitate the pushing pipe to push the protective cover away and reverse, the front end of the pushing pipe is provided with at least 1 seam along the axial direction. When the protective cover is pushed, the front end of the pushing pipe is opened along with the opening of the flexible protective cover, so that the protective cover can be further pushed to be opposite. More preferably, the number of the slits is 4, and the slits are uniformly arranged around the circumference direction, and the front end of the pushing pipe is in a multi-petal openable structure.

Further preferably, the flexible protective cover is made of any one of flexible high polymer materials such as silica gel, rubber, silicone rubber, latex, TPE, TPU, PEBAX and the like.

For the convenience of operation, as preferred, the rear end of fixed pipe is equipped with the handle, and is equipped with the through-hole along the axial in the handle. Through which a flexible tube of a flexible endoscope can be easily inserted and extended from a front end of the fixed tube.

In order to facilitate the operation, the rear end of the pushing pipe is provided with a pushing pipe handle, and the pushing pipe handle is slidably sleeved on the fixed pipe.

The material of propelling movement pipe is any one of nylon, PC, PP, ABS, TPU, PVC, PFA, FEP, ETFE, PE, PEEK, TPE.

The utility model discloses the technological effect who gains does: when in use, the endoscope hose penetrates through the fixed tube and penetrates out of the front end of the fixed tube, and enters the human body together; after the foreign body forceps extend out of the endoscope forceps channel hole to grasp foreign bodies, the pushing pipe is pushed forwards and the soft protective cover is pushed out until the direction is opposite, so that the foreign bodies can be covered by the soft protective cover, and then the foreign bodies, the endoscope and the instrument are withdrawn from the human body channel together. Therefore, the foreign body can be prevented from scratching the intact tissue, and the protective effect is achieved. Furthermore, compared with the prior art the utility model discloses a foreign matter sheath pipe indication is got to alimentary canal is wider more, and is compatible higher to the change of the length shape of foreign matter etc. can effectively take out rectangular form foreign matter, like long blade, toothbrush handle etc. and the fixed pipe of accessible is kept apart the protection between the human body moreover.
