Abstract: A full-vagina sleeve cylindrical expansion and pneumoperitoneum integrated device, includes: an elastic embedded ring (1) and a sleeve (2). The elastic embedded ring (1) is made of elastic material and embedded inside a pelvic outlet. The elastic embedded ring (1) is capable of expanding in a natural state inside a vagina to tightly adhere to wall of the vagina, or being inflated into an annular ring which tightly adheres to the vagina wall so as to elastically expand a vagina tissue. The sleeve (2) is made of elastic material or a non-elastic material and is cylinder-shaped. A front end ring of the sleeve (2) is connected with the elastic embedded ring (1), and a rear end ring extends out of the vagina. An operation mask (3) is fixedly provided on the rear end ring.

Abstract: A protection device for preventing tumor dissemination and tumor metastasis in a laparoscopic surgery includes a soft bag (1) for containing a resected tumor during the surgery provided in an abdominal cavity through a puncture in an abdominal wall, and a sealing thread (2) provided around a mouth of the soft bag (1). An instrument is able to be put into the soft bag in the abdominal cavity through the mouth of the soft bag (1) outside the abdominal cavity for inflating and crushing, or the instrument is able to be put into the soft bag in the abdominal cavity for operation and observation through a conduit shaped structure for a breaking operation (3) or a conduit shaped structure for an auxiliary operation (4) or a conduit shaped structure for peering (5).
