[0025] As shown in Figure 1 and Figure 2 A kind of animal pathological examination tissue sample fast sampling tool, including roller 1, roller 1 is uniformly surrounded with sampling port 11 around, the lower end of sampling port 11 is equipped with adjusting structure 2, sampling port 11 is equipped with sampling groove 13, sampling port 11 is fixedly connected with connecting rod 14 on the side close to roller 1, the end close to adjusting structure 2 of roller 1 is fixedly connected with protective shell 15 of the sleeve set in the outside of adjusting structure 2, adjusting structure 2 includes and roller 1 fixed connection rotating rod 21, the other end of rotating rod 21 is movably connected with push rod 22, the outside of push rod 22 is equipped with and the outer shell 12 corresponding to rotating rod 21.

[0026] In this embodiment, by setting a push rod 22, the push rod pushes the rotating rod 21 forward under the control of the operator, thereby driving the rotating rod to advance along a predetermined trajectory. The advancing action of the rotating rod 21 is matched by the outer shell 12, so that the rotating rod 21 generates a rotating motion. This rotating motion is further transmitted to the roller shaft 1, causing the roller shaft 1 to rotate, achieving gentle contact and sampling of the animal's skin. The sampling port 11 is fixed on the roller shaft 1 and performs a circular motion with the rotation of the roller shaft, contacting the animal's skin in a manner similar to combing, thereby effectively collecting skin debris and hair samples without causing discomfort or stress reaction to the animal.

[0027] During sampling, the linear motion of the push rod 22 is converted into the rotating motion of the rotating rod 21, and this motion conversion mechanism ensures the smoothness and consistency of the sampling action. The design of the sampling port 11 allows it to gently contact the animal's skin during rotation, reducing the stimulation to the animal while effectively collecting the required tissue samples. In addition, the geometry and material selection of the sampling port 11 aim to minimize damage to the skin while ensuring the representativeness and integrity of the sample. Through this design, the utility model not only improves the efficiency and quality of sampling, but also reduces the potential harm to the animal, providing a more humane and scientific sampling method for animal pathology examination.

[0028] As shown in Figure 3 and Figure 4 , the outer diameter of the outer shell 12 and the inner diameter of the protective shell 15 correspond, the outer shell 1 is provided with a sliding groove 16 penetrating itself, the two sides of the sliding groove 16 are provided with a limiting groove 17 placed inside the outer shell 1, the push rod 22 is fixedly connected with a sliding member 23 corresponding to the sliding groove 16 and the limiting groove 17 on the side close to the sliding groove 16, the sliding member 23 is fixedly connected with a push member 24 sleeved outside the outer shell 12 on the side away from the push rod 22, the rotating rod 21 is fixedly connected with a T-shaped limiting member 25 placed inside the push rod 22 on the end close to the push rod 22, the rotating rod 21 is sleeved with a spiral protrusion 26, the outer shell 12 is provided with a track groove 27 corresponding to the protrusion 26.

[0029] In this embodiment, the outer diameter of the outer shell 12 precisely matches the inner diameter of the protective shell 15, ensuring the stability and accuracy of the push rod 22 when pushing the rotating rod 21. The outer shell 12 is provided with a sliding groove 16 that penetrates itself, and the sliding groove is provided with limiting grooves 17 on both sides, which are used to fix and guide the movement of the sliding piece 23, ensuring the smoothness and accuracy of the push rod 22 during pushing. The sliding piece 23 is fixedly connected to the side of the push rod 22 close to the sliding groove 16, which corresponds to the sliding groove 16 and the limiting groove 17, ensuring the stability of the push rod during pushing. The sliding piece 23 is fixedly connected to the pusher 24 away from the push rod 22, which is sleeved outside the outer shell 12, further enhancing the stability of the push rod and the convenience of operation. The rotating rod 21 is fixedly connected to the T-shaped limiting piece 25 close to the push rod 22, which is placed inside the push rod 22 and is used to limit the rotation angle of the rotating rod, ensuring that the rotating movement of the rotating rod is within the predetermined range, thereby ensuring the consistency and repeatability of the sampling process. The rotating rod 21 is sleeved with spiral protrusions 26, which correspond to the track grooves 27 inside the outer shell 12. When the rotating rod rotates, the protrusions move along the track grooves, realizing the conversion between the rotating movement of the rotating rod and the linear movement of the push rod. At the same time, it ensures that the protrusions 26 maintain a small degree of tightness, ensuring that the rotating rod 21 can rotate normally.

[0030] In use, first, place the sampling tool in the appropriate position of the animal to be sampled, ensuring that the roller shaft 1 can contact the surface of the animal's skin. Adjust the contact pressure between the sampling port 11 and the animal's skin by adjusting the structure 2 to adapt to the thickness and sensitivity of different animal skins. The operator holds the push rod 22 and pushes it forward, and the linear movement of the push rod 22 is transmitted to the sliding piece 23 through the sliding groove 16 and the limiting groove 17 of the outer shell 12, and the sliding piece 23 is engaged with the limiting groove 17, ensuring the smooth advancement of the push rod 22. The pushing of the push rod 22 makes the rotating rod 21 move along the predetermined trajectory and generates a rotating movement through the cooperation of the outer shell 12. The rotating movement of the rotating rod 21 is transmitted to the roller shaft 1, causing the roller shaft 1 to rotate, and the sampling port 11 performs a circular motion, gently contacting the animal's skin, achieving an action similar to combing, effectively collecting skin debris and hair samples. As the roller shaft 1 rotates, the sampling groove 13 on the sampling port 11 collects skin debris and hair samples. After sampling is completed, remove the sampling tool from the animal, and fix the rotating rod 21 in the appropriate position through the cooperation of the T-shaped limiting piece 25 on the rotating rod 21 and the track groove 27 inside the outer shell 12, in order to safely extract the sample from the sampling port 11. Finally, the collected samples are subjected to pathological examination for disease diagnosis or other related research.

[0031] During the whole sampling process, the cooperation between the spiral protrusions 26 outside the rotating rod 21 and the track grooves 27 inside the outer shell 12 ensures the smooth conversion between the rotating movement of the rotating rod and the linear movement of the pushing rod, while ensuring the consistency and repeatability of the sampling process. In addition, the design and material selection of the sampling port 11 aim to minimize the damage to the skin, ensuring the representativeness and integrity of the sample. Through this design, the sampling tool of the utility model not only improves the efficiency and quality of sampling, but also reduces the potential harm to animals, providing a more humane and scientific sampling method for animal pathological examination.

[0032] Although the utility model has been disclosed as above with preferred embodiments, it is not intended to limit the utility model, and anyone skilled in the art can make various modifications and modifications without departing from the spirit and scope of the utility model, therefore the protection scope of the utility model should be defined by the claims.
