Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and specifically to a simple device for collecting hysteroscopy specimens. Background Art

[0002] Hysteroscopy surgery is a minimally invasive surgical technique widely used in the field of obstetrics and gynecology. Using hysteroscopy instruments, it enters the uterine cavity through a female's vulva, vagina, and cervix. With the aid of computer imaging technology, it can clearly and intuitively observe the morphology of the uterine cavity, the condition of the endometrium, and the condition of the bilateral fallopian tubes, and perform necessary surgical treatments on this basis. Hysteroscopy surgery has the advantages of small trauma, fast recovery, and few complications, and is widely used in the diagnosis and treatment of various gynecological diseases.

[0003] During hysteroscopy surgery, the hysteroscope needs to be inserted through the vagina and cervix into the uterine cavity, and distending fluid is injected to expand the uterine cavity, so as to clearly observe the morphology and lesions in the uterine cavity. When the lesion site is located, the lesion site can be resected or sampled. The resected sample flows out with the distending fluid. When collecting hysteroscopy specimens, a mesh bag or collection bag is usually used for filtration. The above-mentioned collection bag often has only one chamber and is only used for collecting a single specimen. When there are multiple lesion samples in the uterus, it is easy to cause specimen mixing; if the specimen collection bag is replaced during the collection process, it will increase the process, cause waste of resources, and prolong the operation time.

[0004] The prior art such as CN210673363U discloses a specimen sampling bag for gynecological hysteroscopy surgery. Although this patent sets multiple chambers in the collection bag, the device is relatively complex and the use cost is relatively high. In addition, the openings of each chamber in the collection bag are relatively small, which is not conducive to quickly collecting the samples in the distending fluid; in addition, due to the small openings, the samples are also likely to enter the wrong chamber during the collection process. Summary of the Invention

[0005] The purpose of the present invention is to provide a simple device for collecting hysteroscopy specimens, which can classify and place hysteroscopy specimens while ensuring that the opening is in a fully open position when collecting the corresponding specimens, so as to quickly and accurately classify and collect hysteroscopy specimens.

[0049] The fixing ring 2 is provided with a bag mouth fixing member 3, and the specimen collection mesh bag 1 is detachably connected to the fixing ring 2 through the bag mouth fixing member 3.

[0050] In this embodiment, the bag mouth fixing member 4 is a protruding portion 31 provided on the fixing ring 2; the number of the protruding portions 31 is multiple and they are evenly distributed along the fixing ring 2.

[0051] The top of the specimen collection mesh bag 1 is provided with a bag mouth 11, and a partition net 12 is arranged inside. The lower part and the edge position of the partition net 12 are fixedly connected to the inner wall of the specimen collection mesh bag 1. The partition net 12 divides the specimen collection mesh bag 1 into an inner mesh bag 13 and an outer mesh bag 14, and correspondingly divides the bag mouth 11 into an inner mesh bag mouth 111 and an outer mesh bag mouth 112.

[0052] During operation, medical staff can switch the opening and closing of the inner mesh bag mouth 111 and the outer mesh bag mouth 112 by adjusting the fixing position at the top of the partition net 12. As shown in the figure, when the medical staff hangs the partition net 12 on the protruding portion 31 on the right side, the inner mesh bag mouth 111 can be opened while the outer mesh bag mouth 112 is closed. When different specimens need to be collected, the partition net 12 can be hung on the protruding portion 31 on the left side, closing the inner mesh bag mouth 111 and opening the outer mesh bag mouth 112 at the same time.

[0053] Embodiment 2

[0054] This embodiment discloses a simple collection device for hysteroscope specimens.

The insertion portion 344 can pass through the mesh holes in the partition net 12, thereby effectively fixing the partition net 12.

[0059] This embodiment is a further improvement based on Embodiment 1. In Embodiment 1, when switching the opening and closing of the bag mouth 11, it is necessary to remove the partition net 12 from the protruding portion 31 and then hang it on the protruding portion 31 on the opposite side. If there are multiple protruding portions 31 on which the partition net 12 is hung, it is necessary to remove the partition net 12 at the corresponding positions simultaneously and then hang them on the opposite positions one by one, and the operation is relatively cumbersome.

[0060] In this embodiment, the extension portion 121 of the partition net 12 can be integrally fixed to the partition net fixing portion 34, and then the partition net fixing portion 34 is flipped to the left or right to complete the switching of the opening and closing of the inner bag mouth 111 and the outer bag mouth 112.

[0062] The side fixing member 35 includes a handle 351, a pull rod 352, and a hook plate 353; a sleeve 36 is provided on the pressing ring 32, the pull rod 352 is inserted into the sleeve 36, and the handle 351 and the hook plate 353 are respectively provided at both ends of the pull rod 352. An elastic snap ring 354 is provided on the pull rod 352.

[0063] The side fixing member 35 is mainly used to fix the side portion of the specimen collection net bag 1 to prevent the side portion of the specimen collection net bag 1 from retracting inward and leaving a gap between the side portion of the specimen collection net bag 1 and the pressing ring 32 during the process of collecting specimens. When in use, the handle 351 can be pushed towards the center of the pressing ring 32, the hook plate 353 is placed into the interior of the specimen collection net bag 1 through the gap of the specimen collection net bag 1, and then the hook plate 353 is rotated to hook the specimen collection net bag 1. Then the handle 351 is pulled back, so that the hook plate 353 that hooks the side portion of the specimen collection net bag 1 is retracted and the specimen collection net bag 1 is pressed against the position of the pressing ring 32 to achieve the fixation of the side portion of the specimen collection net bag 1. The elastic snap ring 354 has elasticity and can pass through the sleeve 36 and be clamped at both ends of the sleeve 36 during the process of pushing and pulling the handle 351 to achieve the self-locking effect.
