detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Fig. 1-Fig. 6, the utility model provides a kind of technical scheme:

A cervical canal scraping tissue sample collector, comprising: a scraping collection structure and an edge collection structure.

As shown in Figures 1-6, the composition of the scraping collection structure: the scratching collection structure includes a U-shaped plate 1, the U-shaped plate 1 is fixedly connected with an extending shell 5, and the inner thread of the extending shell 5 is connected with a threaded rod 3. One end of the threaded rod 3 is rotatably connected with a connecting head 13, and a plurality of connecting rods 14 are hinged inside the connecting head 13, and one end of the connecting rod 14 is hinged with a U-shaped rod 12, and the U-shaped rod 12 is movably connected to the shell 5 The inside of the U-shaped bar 12 is fixedly connected with a scraper 4, and the inside of the scraper 4 is provided with a plurality of meshes 15.

As shown in Figures 1-6, the principle of the scraping collection structure: by turning the second handle 10 to drive the threaded rod 3, the threaded rod 3 is threadedly connected with the shell 5, and pushes the connector 13 in a direction away from the second handle 10 , the connecting head 13 moves to change the angle with the connecting rod 14, and then pushes the U-shaped rod 12, pushes the scraper 4 outward, sticks to the cervical canal for scratching, and collects tissue samples conveniently.

As shown in Figure 2-Figure 3, the composition of the edge acquisition structure: the edge acquisition structure includes a tube body 2, which is sleeved on the outside of the threaded rod 3, and the tube body 2 is slidably connected to the inside of the U-shaped plate 1, and the tube body One end of 2 is fixedly connected with an open case 6, and the open case 6 is slidably connected with the U-shaped plate 1, and the outside of the open case 6 is connected with a connecting pipe 7, and the outside of the U-shaped plate 1 is fixedly connected with a collection case 8 One end of the connecting pipe 7 communicates with the inside of the collecting shell 8, and the inside of the collecting shell 8 is movably connected with tissue fluid collecting cotton 11.

As shown in Figures 2-3, the principle of the edge collection structure: by pushing the first handle 9 to drive the tube body 2, the tube body 2 drives the open shell 6, so that the open shell 6 is attached to the cervical orifice, and the The interstitial fluid flowing out from the edge that is not collected by the collection structure is scraped to collect, and part of the collected interstitial fluid flows into the collection shell 8 through the connecting tube 7, and the interstitial fluid collection cotton 11 collects it.

In order to facilitate pulling the tube body 2 , a plurality of first handles 9 are fixedly connected to the outside of the tube body 2 .
