DETAILED DESCRIPTION

[0048] In order for those skilled in the art to better understand the technical scheme of the present application, the present application will be further described in detail below with reference to the drawings. Example one:

[0049] Please refer to Figures 1-7 A gastrointestinal endoscope resection polypus collector, comprising a negative pressure assembly 1 and a gastrointestinal endoscope 3, further comprising a collection assembly 2, which is sealed and detachably connected to one end of the gastrointestinal endoscope 3, and which can separate waste liquid generated during the resection polypus surgery from the polypus.

[0050] The specific implementation is that, during the surgery of resecting polypus, under the negative pressure generated by the negative pressure assembly 1, the gastrointestinal endoscope 3 sends the mixture of resected polypus and waste liquid into the inner cavity of the collection assembly 2 through its working channel, the polypus is effectively intercepted, and the waste liquid is discharged; after the surgery is completed, the doctor can easily take out the polypus in the collection assembly 2 for subsequent processing.

[0051] The collection assembly 2 comprises:

[0052] The shell 21 is sealed and detachably installed at one end of the gastrointestinal endoscope 3;

[0053] The separation assembly 22 is installed on the inner wall of the shell 21.

[0054] The specific implementation is that the shell 21 is designed with an interface matched with one end of the gastrointestinal endoscope 3, and the sealed detachable connection with the gastrointestinal endoscope 3 is realized through a sealing structure. This design not only ensures the air tightness during the surgery to prevent waste liquid leakage, but also facilitates cleaning, disinfection or replacement of the collection assembly 2 after the surgery.

[0055] The separation assembly 22 is mounted on the inner wall of the shell 21, which can realize effective separation of the waste liquid and the polyp, ensure the integrity and purity of the polyp, and avoid pollution of the waste liquid to the surgical environment or subsequent treatment process.

[0056] Before the operation, the collection assembly 2 is sealed and mounted on one end of the gastrointestinal scope 3, and the connection is checked for tightness without leakage; the negative pressure assembly 1 is started, so that a stable negative pressure environment is formed in the negative pressure pipeline, providing power for the flow of the waste liquid and polyp mixture; the doctor performs polyp resection operation through the gastrointestinal scope 3, and the mixture generated enters the inner cavity of the shell 21 through the working channel; the mixture realizes separation of the waste liquid and the polyp at the separation assembly 22, and the waste liquid is discharged and the polyp is collected.

[0057] After the operation, the negative pressure assembly 1 is closed, the collection assembly 2 is disassembled, the polyp is taken out for subsequent processing, and the collection assembly 2 is cleaned and disinfected.

[0058] The shell 21 comprises:

[0059] The shell 211 is a semi-cylindrical cavity, and one side thereof is sealed and detachably connected with one end of the gastrointestinal scope 3;

[0060] The liquid inlet hole one 212 is formed through one side of the shell 211;

[0061] The liquid inlet hole two 213 is formed through one side of the shell 211, and is located on the same side as the liquid inlet hole one 212.

[0062] Specifically, the shell 211 is designed as a semi-cylindrical cavity, which can form sufficient space inside to accommodate the separation assembly 22 and the collected polyp. One side of the shell 211 is designed with a sealed interface, through which the sealed and detachable connection with one end of the gastrointestinal scope 3 is realized. This connection ensures the airtightness during the operation, preventing leakage of the waste liquid and the polyp.

[0063] The liquid inlet hole one 212 and the liquid inlet hole two 213 are both formed through one side of the shell 211, and they are located on the same side. The design of these holes corresponds to the working channel of the gastrointestinal scope 3.

[0064] During the operation, when the gastrointestinal scope 3 performs polyp resection operation, the waste liquid and polyp mixture generated first flows out through the working channel of the gastrointestinal scope 3, and then enters the inside of the shell 211 through the liquid inlet hole two 213,

[0065] They will encounter the separation assembly 22 mounted on the inner wall; the separation assembly 22 separates the waste liquid and the polyp through its filtering and separating function.

[0066] The separation assembly 22 comprises:

[0067] a liner 223 movably mounted on the inner wall of the shell 211, and the arc surface of the liner 223 can slide along the arc inner wall of the shell 211;

[0068] a liquid inlet hole three 226 formed through the side of the liner 223;

[0069] a rotating shaft 225, the two ends of which are respectively rotatably connected to the two sides of the inner wall of the shell 211, and the outer side of which is fixedly connected to the liner 223;

[0070] a partition plate 228 fixedly mounted on the inner wall of the liner 223, and the inner cavity of the liner 223 is divided into two cavities by the partition plate 228;

[0071] a blocking net 222 fixedly mounted on one side of the liner 223;

[0072] a baffle 224, one side of which is fixedly mounted on the outer side of the rotating shaft 225, and the baffle 224 is clamped with the inner wall of the shell 211, and a sealing rubber strip is fixedly mounted at the connection between the baffle 224 and the inner wall of the shell 211;

[0073] a liquid outlet hole one 227 formed through one side of the arc surface of the liner 223;

[0074] a liquid outlet hole two 229 formed through one side of the arc surface of the liner 223, and the liquid outlet hole two 229 and the liquid outlet hole one 227 are respectively located on the two sides of the partition plate 228.

[0075] Specifically, the liner 223 is movably mounted on the inner wall of the shell 211 through the rotating shaft 225, and the arc surface of the liner 223 can smoothly slide along the arc inner wall of the shell 211. The partition plate 228 divides the inner cavity of the liner 223 into two cavities with the same volume, the first inner cavity is close to the blocking net 222, and the second inner cavity is away from the blocking net 222.

[0076] During the polyp resection surgery, the waste liquid and polyp mixture first flows out through the working channel of the gastrointestinal endoscope 3, and then enters the inside of the shell 211 through the liquid inlet hole two 213. The polyp is intercepted by the blocking net 222, and the waste liquid passes through the blocking net 222 into the first inner cavity of the liner 223 and is discharged through the liquid outlet hole two 229.

[0077] The liquid inlet hole three 226 is formed through one side of the liner 223. When the staff lifts the baffle 224 upward after the polyp resection is completed, the baffle 224 drives the liner 223 to rotate 60 degrees around the rotating shaft 225, the liquid inlet hole three 226 is aligned with the liquid inlet hole one 212 on the shell 211, the waste liquid enters the second inner cavity of the liner 223 through the liquid inlet hole one 212 of the shell 211 and the liquid inlet hole three 226 of the liner 223, and is discharged through the liquid outlet hole one 227. In this state, the top of the blocking net 222 is flush with the top of the shell 211, and the staff can easily take out the polyp.

[0078] After the operation, the doctor can rotate the inner container 223 through the baffle 224, so that it rotates along the rotation shaft 225, thereby facilitating subsequent cleaning and maintenance. At the same time, the clamping design of the baffle 224 and the inner wall of the shell 211 and the use of the sealing rubber strip ensure the stability and sealing of the inner container 223 during rotation, preventing leakage of waste liquid and polyps.

[0079] In summary, the separation assembly 22 realizes efficient separation and collection of waste liquid and polyps, and facilitates subsequent cleaning and maintenance, thereby not only improving the safety and efficiency of the operation, but also reducing the work burden of medical staff.

[0080] It also includes a liquid outlet pipe 4 which penetrates the bottom of the shell 211, and which is fixedly connected with the penetration.

[0081] The specific implementation is that when the top of the baffle 224 is flush with the top of the shell 211, it is the initial state of the collection assembly 2, and in the initial state, the liquid outlet pipe 4 is connected with the first inner cavity of the inner container 223 through the liquid outlet hole two 229, thereby discharging the waste liquid; when the top of the interception net 222 is flush with the top of the shell 211, the liquid outlet pipe 4 is connected with the second inner cavity of the inner container 223 through the liquid outlet hole one 227, thereby discharging the waste liquid.

[0082] The gastrointestinal endoscope 3 includes:

[0083] The outlet one 32 is detachably connected with the liquid inlet hole two 213 at one end;

[0084] The outlet two 33 is detachably connected with the liquid inlet hole one 212 at one end;

[0085] The main body 31 is fixedly connected with the other end of the outlet one 32 and the outlet two 33, and is connected with the outlet one 32 and the outlet two 33.

[0086] The specific implementation is that in the initial state, the mixture of waste liquid and polyps enters the inner cavity of the shell 211 through the outlet one 32 and the liquid inlet hole two 213; when the top of the interception net 222 is flush with the top of the shell 211, the outlet one 32 is blocked by the inner container 223, and the outlet two 33 coincides with the liquid inlet hole three 226 through the liquid inlet hole one 212.

[0087] The negative pressure assembly 1 includes:

[0088] Two waste liquid bottles 12, one of which is connected with the liquid outlet pipe 4 in a sealed manner;

[0089] The connecting pipe 14 is connected with the two waste liquid bottles 12 in a sealed manner at both ends;

[0090] The gas outlet hole 13 penetrates the top of the other waste liquid bottle 12, and is fixedly connected with the penetration.

[0091] The negative pressure host 11 sucks the waste liquid generated during the polyp resection surgery through the suction tube and transports it to the waste liquid bottle 12 for temporary storage, and sucks the polyp resected during the polyp resection surgery into the inner cavity of the shell 211 through the suction tube.

[0092] Specifically, the negative pressure assembly 1 generates suction force through the negative pressure host 11, and uses the suction tube to suck out the waste liquid and the resected polyp generated during the surgery, respectively. At the same time, the waste liquid bottle 12 and the connecting pipe 14 form a closed loop system for temporary storage and treatment of waste liquid. The air outlet hole 13 is responsible for balancing the pressure in the waste liquid bottle 12 to ensure the stable operation of the negative pressure system. This is prior art and will not be described in detail here. Embodiment Two:

[0093] This embodiment provides a technical solution based on embodiment one: the shell 211 and the inner container 223 are internally provided with a plurality of magnets 221, which are distributed in a circumferential array, and the acute angle between the connecting lines of adjacent magnets 221 and the center is 60 degrees. The magnets 221 built-in the shell 211 and the magnets 221 built-in the inner container 223 can attract each other, and in the initial state, they are one-to-one corresponding.

[0094] Specifically, through the mutual attraction between the magnets 221, the shell 211 and the inner container 223 can be tightly fixed together, and the close fit of the magnets 221 also helps to improve the sealing between the shell 211 and the inner container 223. When the two are tightly connected through the magnets 221, the gap between them will be greatly reduced, thereby preventing the penetration of liquid. This is crucial for medical devices that need to maintain a clean or sterile internal environment. Although the attraction of the magnets 221 tightly fixes the shell 211 and the inner container 223, it is convenient to disassemble, and the shell 211 and the inner container 223 can be easily separated for cleaning and maintenance.

[0095] The circumferential array distribution of the magnets 221 also helps to achieve precise positioning and alignment between the shell 211 and the inner container 223. During assembly, the attraction of the magnets 221 will guide the inner container 223 to automatically align with the corresponding position in the shell 211, thereby ensuring the accuracy and reliability of the device.

[0096] In summary, the built-in magnets 221 of the shell 211 and the inner container 223 not only enhance the stability and sealing of the device, but also improve the convenience of disassembly and cleaning.

[0097] Working principle: when using, the collecting assembly 2 is in the initial state, before the operation starts, connect the outlet one 32 and the liquid inlet hole two 213, connect the outlet two 33 and the liquid inlet hole one 212, and check whether the connection is tight and has no leakage; start the negative pressure assembly 1, so that a stable negative pressure environment is formed in the negative pressure pipeline, and power is provided for the flow of the waste liquid and the polyp mixture; the doctor performs the polyp resection operation through the gastrointestinal endoscope 3, the mixture generated is introduced into the inside of the shell 211 through the outlet one 32 and the liquid inlet hole two 213, the polyp is intercepted by the intercepting net 222, the waste liquid passes through the intercepting net 222 and enters the first inner cavity of the inner container 223, and is discharged to the waste liquid bottle 12 through the liquid outlet pipe 4;

[0098] When the polyp resection is completed, the staff lifts the baffle 224 upward, the baffle 224 drives the inner container 223 to rotate 60 degrees around the rotating shaft 225, the liquid inlet hole three 226 is coincided with the liquid inlet hole one 212 on the shell 211, the waste liquid enters the second inner cavity of the inner container 223 through the liquid inlet hole one 212 on the shell 211 and the liquid inlet hole three 226 on the inner container 223, and is discharged through the liquid outlet hole one 227, in this state, the top of the intercepting net 222 is flush with the top of the shell 211, and the staff can easily take out the polyp.

[0099] The above only describes some exemplary embodiments of the present application by way of illustration, without doubt, for ordinary skilled in the art, the described embodiments can be modified in various ways without departing from the spirit and scope of the present application.
