If the outer sleeve remains stationary, pushing the inner sleeve forward can fully expand the opening device and the mouth of the bag, but it may cause serious damage or even breakage of the bag, resulting in tissue fragments of the bag leakage).

4. Put the diseased tissue removed during the operation into the bag (note: the volume of the included object should not exceed the maximum capacity of the bag of each specification in the above table).
