Description

Technical Field

[0001] This utility model relates to a collection device for polyps cut under endoscopy on a negative pressure pipeline, belonging to the field of surgical instrument technology. Background Technology

[0002] With the advancement of medical technology, the removal of polyps in the bladder and gastrointestinal cavities is now performed endoscopically via a main incision channel that inserts a miniature observation lens and a miniature cutting device. A negative pressure tube is then inserted through this main incision channel to aspirate the removed polyp along with intracavitary secretions, blood, and externally administered flushing fluid. This eliminates the need for an abdominal incision, thus reducing the size of the surgery, lowering surgical risks, and alleviating patient suffering.

[0003] Polyps extracted using the above methods usually require pathological examination to check for malignant lesions. The traditional method involves collecting the aspirate in a container, filtering it with gauze, washing the filtered polyps, and then temporarily storing them in a formaldehyde-based preservation solution for later testing.

[0004] The process of collecting polyps and placing them in formaldehyde is too cumbersome. Sometimes it is even necessary to manually sort out the polyps one by one, wash them, or put them into formaldehyde, which increases the workload and delays the operation time.

[0005] A search revealed that application number CN202323645493.8, entitled "A Negative Pressure Suction Tube and Negative Pressure Suction Assembly for Gastrointestinal Endoscopy Polyps," discloses the following technical solution: A negative pressure suction tube for gastrointestinal polyps is disclosed, used to connect and communicate the negative pressure suction interface of a gastroscope or colonoscope with the negative pressure suction bottle of a negative pressure aspirator, thereby filtering out the removed polyps during gastrointestinal polyp removal surgery. The tube includes a tube body and a mesh bag. This invention also provides a negative pressure suction assembly, including a negative pressure suction tube for gastrointestinal polyps and a negative pressure aspirator. This invention allows surgeons to have high selectivity and control over whether to filter, when to filter, the filtration time, and the sample size of the human tissue fluid containing polyps extracted during gastrointestinal polyp removal surgery. It also facilitates the surgeon's rapid filtration and separation of the extracted polyp tissue containing blood or tissue fluid, thereby obtaining the removed polyp sample.

[0006] According to paragraph 0038 of the utility model specification, the drawback of the above technical solution is that after the extraction operation is completed, the tube connection needs to be disassembled, and then surgical forceps need to be inserted into the mesh bag inside the tube to remove the polyp clamp, and then subsequent cleaning treatment is performed. If it is found that there are still polyps that have not been completely suctioned, the tube needs to be replaced and suctioned again. Utility Model Content

[0007] The technical problem to be solved by this invention is: how to filter and collect polyps directly during the polyp removal process, and how to conveniently remove the collected polyps directly, clean them, and then pour all or part of them into a formaldehyde-based preservation liquid.

[0008] To address the above problems, the technical solution proposed by this utility model is as follows: A device for collecting polyps cut under endoscopy on a negative pressure pipeline includes a filter screen and a detachable filter container fitted between the front and rear sections of the negative pressure pipeline. The filter screen is located at the bottom of the filter container. The suction flow containing polyps through the negative pressure pipeline passes through the filter container, and the polyps are filtered and retained in the filter container by the filter screen.

[0009] It also includes a front connecting sleeve located between the front section pipe and the filter container. The front end of the front connecting sleeve is an inner interface one that can be sealed and fitted onto the front section pipe, and the rear end is an outer section one with a set diameter. The front end of the filter container is an inner interface two that can be sealed and fitted onto the outer section one of the front connecting sleeve.

[0010] It also includes a rear connecting sleeve between the downstream pipeline and the filter container. The filter container has an external connecting section two at its rear end. The front end of the rear connecting sleeve is an internal interface three that can be sealed and fitted onto the external connecting section two of the filter container, and its rear end is an external section three that can be sealed and fitted into the downstream pipeline.

[0011] The filter container and the rear connecting sleeve are integrally formed.

[0012] While keeping the aperture size of the second inner interface at the front end of the filter container unchanged, the volume of the filter container and the diameter of its filter screen can be set as needed.

[0013] The filter container is also provided with a handle on one side. Beneficial effects

[0014] 1. The process of filtering, removing, washing, and placing polyps into preservation solution is simple and convenient; 2. The entire device or the filter container in the device can be reused repeatedly; 3. Each component is small in size, simple in structure, and easy to manufacture. Attached Figure Description

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings:

[0018] Example 1 like Figure 1 As shown in Figure 4, a collection device for polyps cut under endoscopy on a negative pressure pipeline includes a filter screen 4 and a detachable filter container 1 fitted between the front section 601 and the rear section 602 of the negative pressure pipeline 6. The filter screen 4 is located at the bottom of the filter container 1. The suction material containing polyps through the negative pressure pipeline 6 passes through the filter container 1, and the polyps are filtered and retained in the filter container 1 by the filter screen 4. After the suction material from the endoscope is removed, the filter container 1 can be directly removed, and the retained polyps along with the filter container 1 can be placed in water for washing. Then, all or part of the washed polyps can be poured into a formaldehyde-based preservation solution for preservation. Since the filter container 1 is detachable, it can be cleaned, disinfected, and reused repeatedly. In this way, from the filtration of polyps to the washing and placement in the preservation solution, no additional clamping instruments or containers are needed, making the operation very convenient and allowing for repeated use, thereby saving on operating costs.

[0019] The aforementioned collection device 100 further includes a front connecting sleeve 2 disposed between the front section pipe 601 and the filter container 1. The front end of the front connecting sleeve 2 is an inner interface 201 that can be sealed and fitted onto the front section pipe 601, and its rear end is an outer section 202 of a set diameter. The front end of the filter container 1 is an inner interface 101 that can be sealed and fitted onto the outer section 202 of the front connecting sleeve 2. The aforementioned collection device 100 also includes a rear connecting sleeve 3 disposed between the rear section pipe 602 and the filter container 1. The rear end of the filter container 1 has an outer section 102. The front end of the rear connecting sleeve 3 is an inner interface 301 that can be sealed and fitted onto the outer section 102 of the filter container 1, and its rear end is an outer section 302 that can be sealed and fitted into the rear section pipe 602.

[0020] Before leaving the factory, the inner interface 2 101 at the front end of the filter container 1 is pre-sealed and fitted onto the outer section 202 of the front connecting sleeve 2, and the outer section 2 102 at the rear end of the filter container 1 is pre-sealed and fitted into the inner interface 301 of the rear connecting sleeve 3. During application, the inner interface 201 of the front connecting sleeve 2 is pre-sealed and fitted onto the front section pipe 601, and the outer section 302 of the rear connecting sleeve 3 is pre-sealed and fitted into the rear section pipe 602. In this way, the connection of the collection device to the negative pressure pipe 6 is simply completed during application.

[0021] After the material inside the cavity has been removed, the filter container 1 can be directly pulled out from the front docking sleeve 2 and the rear docking sleeve 3.

[0022] The filter container 1 and the rear connecting sleeve 3 are integrally formed, which makes assembly easier.

[0023] While keeping the aperture size of the inner interface 101 at the front end of the filter container 1 constant, the volume of the filter container 1 and the diameter of its filter screen 4 can be set as needed. This allows the filter container 1 to filter out all the polyps that need to be removed at once.

[0024] A handle 5 is also provided on one side of the filter container 1, which allows the filter container 1 to be held and inserted into the water to clean the filtered polyps, making the operation more convenient.

[0025] Example 2 like Figure 5 As shown, the difference between this embodiment and the first embodiment is that the filter container 1 and the rear connecting sleeve 3 are integrally formed, which makes it easier to assemble and disassemble.

[0026] The above embodiments are only for explaining this utility model. Any improvements or modifications made by others without departing from the principle of this utility model should be considered to fall within the protection scope of this utility model.
