Width.
The utility model is designed specimen bag by original rectangle, is changed to near-end opening, Distal elongate type (i.e. open-mouth
To adapt to the circular or oval of steel ring plate shape, and bag body is slender type), to better adapt to the shape of sample, so that
During extraction bag carries outside tightening, sample is always maintained at longitudinally aligned incision of abdominal wall rather than is directed at incision of abdominal wall sidewards, this
It is simpler that sample takes out specimens from pri.
As preferred technical solution, outside link described in the utility model is equipped with outer knob handle, and fetching rod tail end is equipped with
Handle, handle is equipped with curved forceps passage, medical worker to be facilitated to operate.The steel ring piece leading portion can also be equipped with specimen bag bracing wire
Connector sleeve.
As preferred technical solution, interior loop bar front end described in the utility model is equipped with /V end, and /V end is one
" convex " type structure is provided with specimen bag bracing wire outlet, the outlet of steel ring piece and curved forceps outlet, is respectively used to limitation specimen bag and draws
The direction of displacement of line, steel ring piece and curved forceps, before unused specimen fetching device, steel ring piece is compressed in inside interior loop bar, opening
Place both ends are located at outside the outlet of steel ring piece, and pass through connector sleeve and be connected；Outside link is internally provided with annular stop convex line, with positive stop end
Head is used cooperatively, for preventing interior loop bar from stretching out outside outside link.
Endoscope-assistant surgery described in the utility model specimen fetching device, the advantage is that：It can be conveniently by large volume
Or elongated sample longitudinally takes out and expands the degree of notch without expanding operative incision or diminution, can shorten operating time,
Reduce the incidence of Abdominal Incisional Hernia and infection of incisional wound.
