[0003] In the prior art negative pressure inflatable thoracoscopic laparoscopic bag retrieval process, the negative pressure inflatable thoracoscopic laparoscopic bag retrieval bag is usually composed of a soft bag and a connecting tube. When the doctor needs to remove a foreign object, the negative pressure inflatable thoracoscopic laparoscopic bag retrieval instrument is first inserted into a smaller incision and introduced into the body cavity. The doctor will use an external air source to inject gas into the retrieval bag through the connecting tube to inflate the bag and put the foreign object into the retrieval bag.
[0004] In the prior art, when the negative pressure inflatable thoracolaparoscopic retrieval bag is working, if it is used in a private hospital or a small hospital and some informal medical institutions with many defects, the negative pressure inflatable thoracolaparoscopic retrieval bag is not properly inspected or stored before use. If the retrieval bag has tiny damage or small leaks that are not easily noticeable to the human eye, the gas from the external air source may leak into the retrieval bag, causing the retrieval bag to be unable to open. Because the external gas leaks into the organs inside the human body in the retrieval bag, the gas from the external air source may contain bacteria, which may cause organ damage and wound infection in the body, increasing the cost and time of treatment.
[0005] Therefore, it is necessary to provide a negative pressure inflatable thoracoscopic and laparoscopic retrieval bag to solve the above technical problems. Utility Model Content

If the retrieval bag has small or imperceptible damage and small leaks, the gas from the external air source may leak into the retrieval bag, causing the retrieval bag to be unable to open. Because the external gas leaks into the human body's organs in the retrieval bag, the gas from the external air source may contain bacteria, which is likely to cause organ damage and wound infection in the body, increasing the cost and time of treatment. During the process of setting up the medical catheter, the thoracoscopic and laparoscopic bag retrieval instrument is inserted into a smaller incision and introduced into the body cavity. The thrust generated by the controllable negative pressure inflation device is used to push the guide rod, so that the sealed film bag and the medical catheter are pushed out of the medical steel pipe, and slowly stretch and unfold through the elasticity and flexibility of the medical catheter itself. The sealed film bag stretches with the medical catheter, which effectively solves the problem of stretching the retrieval bag by inflating it with external gas, avoids possible damage to the human body caused by external gas, and effectively avoids the problem of the retrieval bag being unable to stretch in the body cavity.
[0024] First embodiment:
[0025] like Figure 1 , Figure 2 , Figure 3As shown, the negative pressure inflatable thoracoscopic and laparoscopic retrieval bag provided by the utility model includes: a sealed film bag 100, which is commonly used in thoracoscopic and laparoscopic retrieval bag surgery, and is a disposable specimen tissue retrieval bag, which is a small bag, usually made of soft, medical-grade material medical polyethylene or polylactic acid material, and the sealed film bag 100 is provided with a sealed bag opening 101, which is the overall structure of the sealed film bag 100, and a through hole, namely the sealed bag opening 101, is opened at the upper end of the sealed film bag 100. The bag opening slot 102 is provided inside, and the internal through hole of the sealed bag opening 101 is the bag opening slot 102. The bag opening slot 102 is hollow, and a medical catheter 103 is provided inside the bag opening slot 102. The medical catheter 103 penetrates the bag opening slot 102 inside the sealed bag opening 101. The medical catheter 103 is a TPE white injection plastic with a brand name of TEB8752. TPE is a safe, non-toxic, halogen-free thermoplastic elastomer material that does no harm to human skin and is the best choice to replace traditional PVC materials. The elasticity of TPE can prevent the medical catheter from The tube 103 is broken, and has high transparency, hygiene, good resilience, environmental protection and non-toxicity, soft and comfortable touch, excellent anti-yellowing performance and good tear resistance, etc. The requirements of medical products on raw materials are extremely strict. A fixture 104 is fixedly installed at one end of the medical catheter 103, and a medical steel pipe 115 is arranged outside the fixture 104. The medical steel pipe 115 is hollow, and the fixture 104 can move in the medical steel pipe 115.

[0030] Third embodiment:
[0031] like Figure 2 , Figure 3 As shown, a spring 107 is provided at one end of the stabilizer 106. The spring 107 is placed and laid on one end of the stabilizer 106. One end of the spring 107 is fixedly installed on a guide plug 108. The inside of the guide plug 108 is a half groove, and the spring 107 is placed in the half groove inside the guide plug 108.
[0032] By setting the spring 107, the guide column is prevented from moving too fast during the thrust process to generate impact force, which may cause the sealing film bag 100 to break through the organ tissue in the human body cavity. The spring 107 can generate a buffering force, which can effectively allow the sealing film bag 100 to move slowly into the human body cavity.
[0033] Fourth embodiment:
[0034] As shown in the figure, Figure 2 , Figure 3 As shown, a guide column 109 is provided at one end of the guide plug 108, and the guide rod 105 is welded to one end of the guide plug 108 which is in a half groove. A sealing gas plug 110 is provided on the outside of one end of the guide column 109. The sealing gas plug 110 prevents gas from entering the medical steel pipe 115.

[0039] When in use, firstly, before removing the foreign matter in the human body cavity, the laparoscopic bag removal instrument is inserted into a smaller incision and introduced into the body cavity, and the thrust generated by the controllable negative pressure inflation device is used. The negative pressure inflation device pushes the guide rod 105, so that the sealing film bag 100 and the medical catheter 103 are pushed out of the medical steel pipe 115, and slowly stretched and expanded by the elasticity and flexibility of the medical catheter 103 itself, and the medical catheter 103 forms a compression effect when moving into the medical steel pipe 115, so that the medical catheter 103 cannot be stretched inside the medical steel pipe 115. The sealed film bag 100 is stretched out along with the medical catheter 103. When other medical instruments are used to remove foreign objects in the human body cavity, the removed foreign objects are placed in the sealed film bag 100, and then the gas in the catheter 112 is extracted again through the negative pressure suction device. In the absence of gas thrust and the action of the spring 107, the sealed film bag 100 and the medical catheter 103 will enter the medical steel pipe 115. By entering the medical steel pipe 115, the medical catheter 103 will shrink and cannot continue to stretch, and then the thoracoscopic laparoscopic bag retrieval instrument is taken out of the human body cavity.
[0040] The above embodiment is only one of the preferred implementation modes of the present utility model and should not be used to limit the protection scope of the present utility model. Any changes or modifications that are made to the main design concept and spirit of the present utility model without any substantive significance, as long as the technical problems solved are still consistent with the present utility model, should be included in the protection scope of the present utility model.
