The use in one example of scraping collected cartilage tissue is described in detail below.
Holding scraping and collecting device 1
If the user uses the scraping and collecting device 1 including the guide needle 1000, the guide needle 1000 is inserted into the receiving space formed by the connecting portion 130 of the scraping element 100, the connecting member 200 and the holding element 200A, and the guide needle 1000 is used to guide the scraping and collecting device 1 to enter the cartilage tissue surface of the knee joint through the skin incision. Next, the user pulls out the guide needle 1000, and then sequentially mounts the collection bottle 500, the mesh 400, and the extension 600 on the scraping and collecting device 1, thereby starting scraping and collecting the cartilage pieces.
The user holds the connecting part 200 of the scraping and collecting device 1 and drives the scraping part 100 to scrape by operating the connecting part 200. The source of the collecting suction force of the scraping and collecting device 1 is from a suction tube and a dedicated pump connected to the extension piece 600 of the scraping and collecting device 1.
First, the cutting part 122 provided on the scraping part 120 of the scraper 100 is first brought into contact with the cartilage tissue, and the cartilage tissue is scraped by the first curved surface P1 and the second curved surface P2 and/or the upper surface UP of the cutting part 122, and the support part 110 can well receive and accommodate the scraped cartilage tissue in order to prevent the scraped cartilage tissue from falling. The scraped cartilage tissue is then transferred to the collection bottle 500 by being sucked through the opening 121 and through the connector 200. After the scraped cartilage tissue is transferred to the collection bottle 500, the cartilage tissue with a size larger than the aperture size of the screen 400 is retained and collected in the collection bottle 500 by the screen 400, and impurities such as cartilage tissue with a size smaller than the aperture size of the screen 400 and other liquids are filtered out and then completely removed by the suction tube.
Scraping and collecting device 2
The user holds the holding part 200A of the scraping and collecting device 2, and operates the holding part 200A to drive the scraping part 100 to scrape. The scraping and collecting device 2 collects the waste water through opening and closing actions.
First, the user pushes the push button 200C, so that the holder 700 and the scraper 100 do not form an accommodation space, i.e., an open state. The cutting part 122 disposed on the scraping part 120 of the scraping member 100 is firstly contacted with the cartilage tissue, and scrapes the cartilage tissue through the first curved surface P1 and the second curved surface P2 and/or the upper surface UP of the cutting part 122, and the support part 110 can well receive and accommodate the scraped cartilage tissue in order to prevent the scraped cartilage tissue from falling. Then, the user pushes the push button 200C again, so that the holder 700 and the scraper 100 form a receiving space, i.e., a closed state. The scraped cartilage tissue is accommodated in the accommodating space formed by the holder 700 and the scraping member 100, and collected.
The foregoing is by way of example only, and not limiting. All equivalent modifications and variations without departing from the spirit and scope of the present disclosure should be considered as included in the claims.
