Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical instruments, in particular to an improved endoscope retrieval bag. Background Art
[0002] Endoscopic retrieval bags are an indispensable tool in modern minimally invasive surgery. They assist doctors in accurately and safely obtaining and removing tissue specimens or surgical resections from the body without surgery or with minimal trauma. The bag is inserted into the body through the instrument channel using the operating handle, and the tissue specimen or surgical resection is placed into the bag. The bag is then locked by pulling the string at the end of the operating handle and removed through the instrument channel.
[0003] During abdominal surgery, if a large amount of fluid is accumulated and a bag is used to collect it, the fluid will accumulate on the bag, increasing the volume and weight of the bag. The bag with increased weight may encounter greater resistance when it is taken out through the abdominal wall channel, and may even fail to be taken out smoothly because the channel is too small.
[0004] In order to solve the above problems, this application proposes an improved endoscope retrieval bag. Utility Model Content

[0009] The closing portion of the bag body is connected with a tightening line for tightening it, and the end of the tightening line away from the bag body passes through a movable channel opened in the long tube for taking things, and a closing structure is formed between the elastic annular sheet, the bag body and the tightening line.
[0010] Preferably, the tubular suction piece includes a suction tube, which slides through the movable channel. The liquid inlet piece is connected to one end of the suction tube and communicates with it. A piston portion is slidably provided in the suction tube, and one end of the piston portion slides through the end of the suction tube away from the liquid inlet piece. A liquid discharge nozzle is connected to the bottom of the end of the suction tube away from the liquid inlet piece.

DETAILED DESCRIPTION
[0021] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.
[0022] like Figure 1-3 As shown, the improved endoscope retrieval bag proposed by the present invention includes a long retrieval tube 1 and a retrieval bag body 5;
[0023] In this embodiment, a movable channel is provided through the long tube 1 for retrieving objects. A tubular suction member 2 is provided on the long tube 1 that slides through the movable channel. One end of the tubular suction member 2 is connected to a liquid inlet member 3. The tubular suction member 2 includes a suction tube 21 that slides through the movable channel. The liquid inlet member 3 is connected to one end of the suction tube 21 and is connected thereto. A piston portion 22 is slidably provided in the suction tube 21, and one end of the piston portion 22 slides through the end of the suction tube 21 away from the liquid inlet member 3. A liquid discharge nozzle 23 is connected to the bottom of the end of the suction tube 21 away from the liquid inlet member 3. The piston portion 22 includes a piston body 221 that slides within the suction tube 21 and the liquid inlet member 3. One end of the piston body 221 is connected to a shaft 222. The end of the shaft 222 away from the piston body 221 slides through the end of the suction tube 21 away from the liquid inlet member 3. The liquid inlet component 3 includes a liquid inlet pipe 31, one end of which is connected to one end of the suction pipe 21, and the piston body 221 is slidably arranged in the liquid inlet pipe 31. A plurality of spaced liquid inlet holes 32 are opened on the outer periphery of the liquid inlet pipe 31, and both ends of the elastic annular sheet 4 are connected to the end of the liquid inlet pipe 31 away from the suction pipe 21.
[0024] In this embodiment, an elastic annular sheet 4 is provided at one end of the liquid inlet member 3 away from the tubular suction member 2. A notch is formed on the elastic annular sheet 4. Both ends of the elastic annular sheet 4 extend outward from the notch and are connected to the liquid inlet member 3. The retrieval bag 5 is sleeved on the outer circumference of the elastic annular sheet 4.
[0025] In this embodiment, the closing part of the taking bag body 5 is connected with a tightening line 6 for tightening it, and the end of the tightening line 6 away from the taking bag body 5 passes through the movable channel opened in the taking long tube 1, and a closing structure is formed between the elastic annular sheet 4, the taking bag body 5 and the tightening line 6.
[0026] It should be noted that: when the elastic annular sheet 4 and the sampling bag 5 are sent into the body through the instrument channel, the tissue specimen or surgical resection can be placed in the sampling bag 5, and then the tightening line 6 can be pulled to shrink the sampling bag 5. When there is too much fluid in the abdominal cavity, the shaft 222 can be pulled to drive the piston body 221 to slide in the suction tube 21. When the piston body 221 moves outward in the suction tube 21, negative pressure can be generated in the liquid inlet pipe 31 and the suction tube 21. The excess fluid in the abdominal cavity can enter it through the liquid inlet hole 32 opened on the outer periphery of the liquid inlet pipe 31, and then be discharged through the drainage nozzle 23 along the suction tube 21, thereby reducing the accumulation of fluid in the abdominal cavity and preventing the accumulation of fluid from being completely attached to the sampling bag 5. This structure can remove excess fluid in the abdominal cavity during the retrieval process and prevent liquid from accumulating on the sampling bag 5, thereby ensuring that the sampling bag 5 can be smoothly taken out.
[0027] In a specific embodiment, one end of the tightening line 6 away from the taking bag 5 is connected to a pull ring 7 .
[0028] It should be noted that the pull ring 7 is provided to facilitate pulling the tightening line 6 .
[0029] In a specific embodiment, a handle 8 is installed at one end of the long tube 1 close to the pull ring 7 .
[0030] It should be noted that the provided handle 8 facilitates the control of the long tube 1 for operation.
[0031] It should be understood that the above-described specific embodiments of the present invention are merely illustrative of or explanation of the principles of the present invention and do not constitute limitations of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the scope of protection of the present invention. In addition, the appended claims of the present invention are intended to cover all variations and modifications that fall within the scope and metes and bounds of the appended claims, or equivalents thereof.
