Technical Field
The utility model belongs to the technical field of medical equipment, concretely relates to a get sample device for through vagina NOSES.
Background
In recent years, minimally invasive techniques and minimally invasive concepts have been widely developed and popularized, and are gradually rooted in the heart of colorectal surgeons. Under the promotion of the minimally invasive technology and the minimally invasive concept, a new technology of Natural Orifice Specimen Extraction Surgery (NOSES) is generated.
NOSES refers to a surgical operation with excellent minimally invasive effect in which a specimen, an abdominal wall, or other body surface is removed through a natural orifice (rectum, vagina, oral cavity, or the like) without an auxiliary incision, and is called "minimally invasive surgery in minimally invasive surgery". The NOSES has the advantages of no incision, less wound and the like on the basis of ensuring radical treatment of tumors. However, how to take out the surgical specimen from the vagina or anus successfully becomes one of the technical difficulties of NOSES. For female patients with large specimens and unable to take specimens through anus, the vagina has good ductility, so that the vagina becomes an important way for taking specimens for the patients. However, the existing medical instruments cannot effectively and conveniently take out the specimen from the vagina.
