Abstract: A multi-functional soft tissue wound protective sleeve includes: a waste collection bag including a bottom patch and a surface patch connected to form a cavity; a bottom ring to be inserted into a human body, to push away human tissues surrounding the bottom ring to form a surgery space; a flip ring located above the waste collection bag and having an adjustable distance with the bottom ring, to prevent waste from touching a surgical surface; a medical inner membrane connecting the bottom ring to the flip ring and defining a surgery channel to the surgery space; a positioning ring sealed with a hole edge of the surgery through-hole on the bottom patch; and a medical outer membrane connecting the positioning ring to the flip ring so as to guide waste escaping the surgery channel over the flip ring to flow into the waste collection bag.
