[0034] In the figure: 1 outer sleeve, 2 retrieval bag, 3 housing, 41 first rotating shaft, 42 second rotating shaft, 43 first gear, 44 second gear, 51 air guide cover, 52 suction member, 53 intake pipe, 54 exhaust pipe. Specific implementation manner

[0035] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0036] Referring to Figures 1-4 , an endoscopic specimen retrieval bag includes an outer sleeve 1, and further includes: a retrieval bag 2, which is accommodated inside the outer sleeve 1 and has a double-layer structure; a housing 3, which is fixed on the side of the outer sleeve 1 and has an opening on its side;

[0037] The endoscopic specimen retrieval bag further includes a driving structure, which is arranged inside the housing 3. The driving structure includes: a first rotating shaft 41, which is rotatably installed inside the housing 3, and one end extends to the outside of the housing 3. A knob is fixed at the end of the first rotating shaft 41 located outside the housing 3; a second rotating shaft 42, which is rotatably installed inside the housing 3; a first gear 43, which is fixedly sleeved on the first rotating shaft 41; a second gear 44, which is fixedly sleeved on the second rotating shaft 52 and meshes with the first gear 43. The transmission ratio of the first gear 43 to the second gear 44 is greater than 1. When the endoscopic specimen retrieval bag proposed by the present utility model is in use, the staff first inserts the outer sleeve 1 into the patient's body, and then pushes the retrieval bag 2 out from inside the outer sleeve 1. When the unfolding of the retrieval bag 2 is blocked, the staff rotates the knob, so that the knob drives the first rotating shaft 41 to rotate. When the first rotating shaft 41 rotates, it can drive the second rotating shaft 42 to rotate through the meshing of the first gear 43 and the second gear 44. It is worth noting that the transmission ratio between the first gear 43 and the second gear 44 is greater than 1. Under the action of the first gear 43 and the second gear 44, the rotation speed of the second rotating shaft 42 can be accelerated, which enables the second rotating shaft 42 to drive the suction member 52 to rotate at a high speed. The high-speed rotation of the suction member 52 can ensure the air supply effect to the double-layer structure on the retrieval bag 2;

[0038] The endoscopic specimen retrieval bag further includes an air supply structure disposed inside the housing 3. When the driving structure operates, the air supply structure inflates the retrieval bag 2. The air supply structure includes: an air guide hood 51 fixed inside the housing 3, with an avoidance opening formed in the air guide hood 51, and the second rotating shaft 42 passes through the avoidance opening and extends into the interior of the air guide hood 51; an air suction member 52 fixedly sleeved on the part of the second rotating shaft 42 located inside the air guide hood 51. The air suction member 52 includes a sleeve and a plurality of axial flow blades, and the plurality of axial flow blades are all fixed on the sleeve and are circumferentially arrayed; an air inlet pipe 53, one end of which is connected to the air guide hood 51 and the other end extends into the opening; an exhaust pipe 54, one end of which is communicated with the air guide hood 51 and the other end is communicated with the space between the two layers of the retrieval bag 2. When the rotating shaft 42 rotates, it can drive the air suction member 52 to rotate. Since the air suction member 52 includes a plurality of axial flow blades, the air suction member 52 can perform an air extraction action when rotating, and extract the air in the external environment through the air inlet pipe 53. Further, the air suction member 52 discharges the gas into the double-layer structure of the retrieval bag 2 through the exhaust pipe 54, so that the double-layer structure of the retrieval bag 2 is inflated and expanded. The inflated retrieval bag 2 can be fully unfolded, avoiding the obstruction of internal tissues to the full unfolding of the retrieval bag 2, which is beneficial for the staff to put foreign objects into the interior of the retrieval bag 2.

[0039] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
