cylindrical hole 30 and the second cylindrical hole 31 and extend into the transparent circular tube 4, meanwhile, the spring 9 is compressed, the first guide rod 5 and the second guide rod 6 can respectively drive the moving plate 26 and the arc-shaped plate 32 to transversely move, the moving plate 26 drives the second sealing plate 27 to separate from the collecting tube 3, the arc-shaped plate 32 is contacted with the rotating plate 24 and extrudes the rotating plate 24 in the transverse moving process, so that the rotating plate 24 can rotate towards the through hole 23, the rotating plate 24 drives the transverse plate 36 to rotate, the transverse plate 36 drives the rotating shaft 34 to rotate, and the rotating shaft 34 can deform the torsion spring 35, because the distance between the top of the arc plate 32 and the bottom of the circular plate 22 is the same as the thickness of the rotating plate 24, under the action of the arc plate 32, the first sealing plate 25 can be made to cling to the circular plate 22 and seal the through hole 23, and the first guide rod 5 and the second guide rod 6 can respectively drive the third conical rubber plate 28 and the fourth conical rubber plate 29 to move and separate from the first cylindrical hole 30 and the second cylindrical hole 31, in addition, the sliding plate 15 can drive the positioning rod 18 to slide on the circular rod 11, when the positioning rod 18 moves to the position of the positioning hole 10, the tension spring 19 can make the positioning rod 18 extend into the positioning hole 10, the sliding plate 15 can be braked, meanwhile, the first conical rubber plate 7 and the second conical rubber plate 8 can respectively contact with the first cylindrical hole 30 and the second cylindrical hole 31 and seal the same, at this time, the sliding plate 15 can be loosened, the laparoscopic surgical forceps for clamping diseased tissues can be operated, the pathological change tissue is plugged into the collecting pipe 3, the circular plate 22, the rotating plate 24 and the first sealing plate 25 can separate the transparent circular pipe 4 into an upper part and a lower part, when the laparoscopic forceps are operated to cause a mistake, the pathological change tissue only falls on the circular plate 22 and the first sealing plate 25 and does not fall into the abdomen of a patient, so that the safety is ensured, at the moment, the pathological change tissue is only clamped again from the circular plate 22 and the first sealing plate 25 and plugged into the collecting pipe 3, after the pathological change tissue is plugged into the collecting pipe 3, the laparoscopic forceps are pulled again to move the laparoscopic forceps to the upper end part 20, at the moment, the pulling plate 12 is pulled, the pulling plate 12 can drive the positioning rod 18 to move and be separated from the positioning hole 10, when the positioning rod 18 is separated from the positioning hole 10, the spring 9 can reset the sliding plate 15 to the original position, the sliding plate 15 can reset the first guide rod, the first guide rod 5 and the second guide rod 6 can reset the third conical rubber plate 28 and the fourth conical rubber plate 29 and re-seal the first cylindrical hole 30 and the second cylindrical hole 31, the first guide rod 5 and the second guide rod 6 can reset the moving plate 26, the arc plate 32 and the second sealing plate 27, the moving plate 26 and the second sealing plate 27 can re-seal the collecting tube 3 to prevent the pathological change tissue in the collecting tube 3 from flowing out, the torsion spring 35 can reset the rotating plate 24 to the original position because the rotating plate 24 does not extrude the arc plate 32, the laparoscopic forceps can pass through the through hole 23 and the lower end part 21 and the lower outer tube 2.2 again and extend into the abdomen of the patient for operation, after the operation is finished, after the sleeve assembly 2 is taken down from the patient, the sealing cover 16 can be opened to take the pathological change tissue out of the collecting tube 3, in addition, the upper outer tube 2.1 and the lower outer tube 2.2 are unscrewed, can pull down from transparent pipe 4 with last outer tube 2.1 and lower outer tube 2.2, be convenient for wash and disinfect to last outer tube 2.1 and lower outer tube 2.2 and transparent pipe 4 for can practice thrift a large amount of operation time, need not install thimble assembly 2 again many times and replenish inert gas again, reduced medical personnel's intensity of labour, alleviateed the damage to patient's wound, and then can improve operation efficiency, convenient to use.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
