[0021] See also Figure 1-Figure 4 The illustrated device for extracting connective tissue of rat oral mucosa includes an extraction tube 1 and two symmetrically arranged cutting knives 2 at one end of the extraction tube 1. The two cutting knives 2 are arranged in a cone shape. The two cutting knives 2 are connected to the extraction tube 1 through a connecting component. A scraping knife 3 for scraping connective tissue is arranged in the two cutting knives 2. A driving mechanism for driving the cutting knives 2 is arranged on the extraction tube 1.

[0022] The connection assembly includes a connection hole 401 opened at one end of the extraction pipe 1 close to the cutting knife 2, a connection plate 403 is connected to the connection hole 401 via a rotating shaft 402, and one end of the connection plate 403 is connected to the cutting knife 2;

[0023] It should be noted here that: through the combined use of the cutting knife 2 and the scraping knife 3, under the driving action of the driving mechanism, the cutting of the rat oral mucosa and the scraping of the connective tissue can be completed in a continuous operation, and there is no need to exchange and use multiple tools during the extraction process, thereby improving the convenience of the extraction operation while ensuring the efficiency of the extraction of the rat oral mucosa connective tissue.

[0024] See also Figure 2 and Figure 3 , a torsion spring is sleeved on the side wall of the rotating shaft 402 shown in the figure;

[0025] It should be noted here that: by providing the torsion spring, it is convenient to drive the two cutting knives 2 to move closer to each other.

[0026] See also Figure 2 and Figure 3 The driving mechanism shown in the figure includes a driving ring 501 slidably connected in the extraction tube 1, the driving ring 501 is connected to a driving rod 502 through a rotating assembly, one end of the driving rod 502 is fixedly connected to a mounting rod 503, one end of the mounting rod 503 is connected to the scraping knife 3, and the other end of the driving rod 502 is arranged to penetrate the extraction tube 1 and is fixedly connected to a driving plate 504;

[0027] It should be noted that: by setting the driving mechanism, it is convenient to push the two cutting knives 2 to rotate away from each other with the rotating shaft 402 as the center.

[0028] See also Figure 4 The rotating assembly shown in the figure includes an annular rotating groove 601 formed on the inner wall of the driving ring 501, and a plurality of rotating plates 602 are rotatably connected in the annular rotating groove 601, and one end of each rotating plate 602 is connected to the driving rod 502;

[0029] It should be noted here that: through the setting of the rotating assembly, it can provide guidance and limit functions for the rotation of the driving rod 502, and can also drive the driving ring 501 to move synchronously during the movement of the driving rod 502.

[0030] Working principle: When extracting connective tissue from the rat oral mucosa, first, place the rat in an anesthesia induction box for general anesthesia, then fix it on the operating table and keep its head stable. After the rat is fixed, the mouth of the rat is opened by using a mouth opener.

[0031] After the rat's oral cavity is opened, the extraction tube 1 is held, and the cutting knife 2 at one end of the extraction tube 1 is pressed against the position to be extracted, and then the rat's oral mucosa is cut by sliding the cutting knife 2. After the rat's oral mucosa is cut, the cutting knife 2 is pressed against the incision, and then the driving plate 504 is pushed, and under the action of the driving rod 502, the driving ring 501 is pushed to move close to the cutting knife 2;

[0032] When the driving ring 501 is against the inner walls of the two cutting knives 2, the two cutting knives 2 will be pushed to rotate away from each other with the rotating shaft 402 as the center under the mutual force, so that the mucosa at the cutting position will be stretched open. With the continuous pushing of the driving plate 504, when the scraping knife 3 at one end of the mounting rod 503 is against the connective tissue under the mucosa, the scraping knife 3 is driven to rotate on the connective tissue by rotating the driving plate 504, so that the connective tissue is scraped by the rotation of the scraping knife 3. After the scraping of the connective tissue is completed, the pushing of the driving plate 504 is released. At this time, under the action of the resetting component, the scraping knife 3 will be driven to retract into the extraction tube 1, so as to realize the extraction of the connective tissue of the rat oral mucosa. There is no need to exchange and use multiple tools during the extraction process, so that the cutting of the rat oral mucosa and the scraping of the connective tissue can be completed in a continuous operation, thereby improving the convenience of the extraction operation while ensuring the efficiency of the extraction of the rat oral mucosa connective tissue.
