For human minimally invasive speculum surgery, human body tissue specimens/foreign objects are taken out and taken out of the body.
-When a single operation is to cut a plurality of specimens, one specimen bag can perform all specimen removal operations.
-Large surgical specimens(such as kidney, stomach, uterus, intestines, etc.) can be taken out and the specimens can be taken out several times after use, without the need for a large incision, so that it is truly minimally invasive.
