[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.
[0018] like Figure 1-Figure 5 As shown, a combined cell brush for collecting cervical cancer cells described in the present invention includes a grip rod 1 and a mounting tube 2. The grip rod 1 is a hollow structure. The mounting tube 2 is threadedly connected to one end of the grip rod 1. One end of the mounting tube 2 is fixedly connected to a bristle mounting plate 3. The bristle mounting plate 3 is connected to one side of the mounting tube 2 and abuts against one end of the grip rod 1. The bristle mounting plate 3 and the grip rod 1 are in a T-shaped structure. A through hole 4 is opened in the middle of the bristle mounting plate 3. The side of the bristle mounting plate 3 away from the mounting tube 2 is fixedly connected to an outer bristle 5. The other end of the mounting tube 2 slides inside A slider 6 is connected, a connecting rod 7 is fixedly connected to one side of the slider 6, a fixing head 9 is fixedly connected to the end of the connecting rod 7 away from the slider 6, the end of the fixing head 9 is conical and located inside the through hole 4, the diameter of the fixing head 9 is larger than the diameter of the connecting rod 7, and the diameter of the fixing head 9 is smaller than the diameter of the through hole 4, an inner bristle 8 is fixedly sleeved on the outer side of the end of the connecting rod 7 away from the slider 6, and a push rod 11 is fixedly connected to the other side of the slider 6, and the end of the push rod 11 away from the slider 6 is inserted through the side wall of the other end of the gripping rod 1.
[0019] Specifically, a limiting ring 10 is fixedly connected to one end of the grip rod 1. The limiting ring 10 is sleeved and rotatably connected to the outside of the push rod 11. The side of the limiting ring 10 away from the middle of the grip rod 1 abuts against an end of the mounting tube 2 close to the middle of the grip rod 1, which can fix the position of the slider 6 sliding into the mounting tube 2.
[0020] Specifically, the push rod 11 is slidably connected to the side wall of the other end of the grip rod 1. The diameter of the push rod 11 is smaller than the inner diameter of the mounting tube 2. The push rod 11, the slider 6 and the connecting rod 7 are located on the same center line, which is convenient for pushing the slider 6 during use.
[0021] Specifically, the inner bristles 8 are annular structures with multiple bristles installed, and the outer diameter of the annular structure is smaller than the diameter of the fixed head 9. The ends of the inner bristles 8 are all against the inner wall of the mounting tube 2, and the outer bristles 5 are symmetrically arranged in multiple rows on the bristle mounting plate 3, which is convenient for collecting exfoliated cervical cells.
[0022] Specifically, the end of the push rod 11 away from the slider 6 is fixedly connected to a push plate 12. The diameter of the push plate 12 is the same as the outer diameter of the gripping rod 1. The diameter of the push plate 12 is larger than the diameter of the push rod 11. It is convenient to squeeze the push rod 11 during collection to squeeze the fixed head 9 together with the inner bristles 8 out of the through hole 4.
[0023] Specifically, the distance between the two sides of the through hole 4 is the same as the distance between the two sides of the slider 6, and the diameter of the through hole 4 is the same as the inner diameter of the mounting tube 2. The slider 6 can be clamped during collection, thereby fixing the position of the fixed head 9.
[0024] When in use, hold the gripping rod 1, extend one end of the gripping rod 1 connected to the brush mounting plate 3 into the patient's vagina until the outer bristles 5 are attached to the outside of the cervical canal, squeeze the pushing rod 11 through the pushing disk 12, so that the pushing rod 11 drives the slider 6 to slide inside the mounting tube 2, and place the fixing head 9 against the opening of the cervical canal. The end of the fixing head 9 gradually squeezes the cervical canal until it extends into the inside of the cervical canal together with the inner bristles 8, and then rotate the gripping rod 1 to make the inner bristles 8 and the outer bristles 5 inside and outside the cervical canal at the same time, and collect the exfoliated cervical cells at the same time. The number of rotations is more than eight circles to ensure that enough cell samples can be collected, and then pull out the gripping rod 1, break the connecting rod 7 and the mounting tube 2, remove the inner bristles 8 and the outer bristles 5, and store them in a specimen liquid bottle.
